.....the wing's the thing!

By monty stone

a trike,  is  basically a wing, and a bunch of 'other stuff' hung under it. during flight at altitude, to me it is an object of 'adulation' and awe! (with a tinge of 'don't fail me now!). however many air mollecules hit it they are ignored!, but, UV will attack it. we in washington state run screaming for our 'moms' when the sun DOES come out. we don't 'TAN' we 'RUST', one month it came out TWICE! we all stayed indoors both days!  until recently when the trike wing 'gurus' finally began to blurt out the TRUTH about THE  WING! we sure had to squeeze them! , we, average trike drivers were abyssmally ignorant of the 'true nature of 'flex wing flight, now we are ALL eggspurts, more or less, and each of us could convert a stack of tubing and a roll of bedsheet into a wing, that somebody else should be willing to test-fly! !. we are completely at peace with them little engine pishkins hurrying to and fro 80 times a SECOND, just behind our heads. no problem, but that wing is our personal magic carpet, enableing us to enjoy the SECOND most pleasureable experience known to mankind, next only  , of course to sugar coated cream-filled do-nuts. the alluminum parts start to die as soon as they are born, though slowly. the plated fasteners pretty gold stuff starts to 'go somewhere else ' in a few months, but doesn't leave the fitting degraded, only 'unprotected' till the ensuing rust film will then protect from corrosion  . the wire bits get 'longer' but, unless kinked or cut, would probably outlast the other stuff, though mfrs, and wire co's reccommend replacement periodically. the 'jesus' bolt, the most feared and respected bolt in history, is also replaced, periodically, though a 'used' bolt has already been 'tested' and works, whereas a 'new' bolt is an 'unknown' quantity, to each his own. if replacing a 7$ bolt takes your mind off a 'looming' mega $$ wing fabric replacent cost then it works! so, how can we extend the life of our wing. don't ding the leading edge, (or any other wing tubeing), ONLY fly at night, i tried this, using a hand held flash light to help with the landings, and though fun, it has it's limitations.  but if you INSIST on flying in daylight then, realizing the insideos nature of UV degradation we cover, when possible, though it often 'aint possible all the time. i seem to remember some magic 'potion-lotion' that mega$$ yacht sails use to repel uv rays?? i paint my leading edges and outer two panels with a secret latex paint i get from my local hardware store, i tell 'em it's to paint my dogs kennel, i lied, i don't even have a dog, if i told them it was for my wing they would double the price and make me sign a 12page 'waiver', plus a seven day 'waiting' period, credit ck and homeland insecurity interview  . this 'secret' paint seems to accept being frequently rolled up by not cracking or peeling. this is on my 'lowly' northwing, my chronos repels it and looks like a 'molting python'. the french 'trilam' is slightly shiney and doesn't like being painted. when 'observers' point to the 'flakes' i put my finger to my lips and whisper ' prototype boundery layer test'. i recently sent a test patch from my morthwing to the factory and they said i had 10% of life left.  i took this as a  'kind' gesture, but at 82 they are being 'optimistic!,  for the wing also! . kamron said they usually 'retire' the wing fabric at 50% but the frame lives on! so, anyone out there in 'flexwingflyingthingamyland' got any ideas to prolong my life, i meant my wing's life let's have it,.............freazier nutszoff

Motorkite Dreaming (Cool Video Link)

By Rizwan Bukhari

Hi All,

 

Here is a cool link for you to enjoy some trike flying fun video. I own the Motorkite Dreaming dvd (which is different than this, some parts are the same). Fun video for all trike pilots :D

 

I hope you enjoy it

Sun N Fun or Oshkosh or just the Flyins?

By Rizwan Bukhari

Hi all,

 

I live in Boise, ID and have never been to Sun N Fun or Oshkosh and was wondering for someone who has prime interest in Sports/Recreational flying which event (Sun N Fun or Oshkosh) is better.

 

I might visit one of these events this year and was wondering if anyone could give me some tips about their experience to either of the events and what did they like, what were some of the challenges of either of the event.

 

Or, is it just better to attend the local flyins?

 

Regards,

Firesleeve or No Firesleeve, that is the question

By Rizwan Bukhari

Hi all,

 

I was reading up on Rotax 912 engines and realized that same 912s come with Firesleeve and  some without Firesleeve. Which got me thinking why some engines on trikes have Firesleeves and some do NOT? Is this a manufacturer's discretion and some order engines with Firesleeves installed and some without it? and is this an important safety concern?

 

Following is the picture of an engine with firesleeve on it's fuel lines. (The firesleeve is orange in color in this picture).

 

My limited understading is that the purpose of firesleeve is to sustain an engine fire for 5- 15 minutes. Hopefully enough time for you to take necessary steps for your safety.

 

Now my question is

1) Howcome in the above picture, there is no firesleeve on the fuel lines running to the carbs? Are there only few critical areas where a firesleeve is needed?

2) Howcome some trike engines come with them and some don't?

3) Are they important safety item for trike pilots?

4) And the most important question is that can a Firesleeve prevent a Fuel Line Vapor Lock? Or does the Firesleeve NOT play any role in preventing a Fuel Line Vapor Lock?

 

Thanks for your help.

 

Regards,

 

Rizzy

I LOVE 'TECH', BUT........

By monty stone

i consider BALLISTIC RECOVERY SYSTEMS' technology level to be 'stuck' in the '1950' s auto era;  plate glass still used to look through, seat belts not used, or available, no crush zones, steel dashboards, rigid steering columns that ran from behind the front bumper to the chest ,minimalistic door catches that allowed doors to fly open going over a bump,remember 'suicide' doors that hinged at the back ? hoods that slammed back, to de-capitate front seat occupiers, air-bags only a dream of the future. remember 'hitlers revenge' the vw, 8gals of gas sitting on your lap, the vw bus had NO leg protection, a minor parking lot 'prang' resulting in MAJOR leg injuries, ford pinto with a gas filler pipe pushed into the gas tank through a rubber 'o'ring, and then mounted behind the rear 'bumper', in the 'rear end me here, position. (my own pinto had 'flammable' signs riveted all round it till a h/way patrol cop made me drill the rivets out and take 'em off! he probly was a shareholder!)  all these, and many other 'flaws' were fixed, finally, after much blood shed, and 'hand-wringing' of corporate 'penny-counters in the then to be , future.  well, the future  is HERE! the tech is available to take the human deployment out of the equation. it's just gotta be 'modified and adapted to fit the BRS. but, bussiness accumen of , if it costs more, it'll reduce our 'profit margin', and any way, we're selling all these the market can bear, will endure, unless enough pressure is bought to bear! so what if the price doubles from $5k to $10k, if it will STOP ME FROM 'DEADING' MYSELF, it's worth it!  my van has a 'knock' sensor that instantly senses a low octane gulp and retards the next few ignition sparks etc, to avoid damage, or inconvenience to the system. obviously, relying on the human to assess the threat, and  risk, decide and deploy 'AINT WORKING'! of all the trike tragedies that have occured in recent memory most, apparrently were equipped with 'the safety net' of an on-board recovery system, yet not one has saved the occupants. sure, if USED they possibly would have, but NOT relying on the human to deploy. yeah, i know that 'shxt' happens close to the ground, etc, but purchasers of these systems, for considerable $$ should have a better chance of success, than winning the lottery. if i were the 'high mucky-muck of one of these companies i would lock my chief designer in a cage, feed him on 'red meat' only until he comes out with a viable system to use TECH to overcome the human shortcomings of F.T.D. (failure to deploy). until then i'd replace that 'puny' little T handle with a 10 inch dia red 'panic' button mounted directly in front of the pilot's face hooked to a 'loud scream detector' wired to the deployment device as 'backup'. WHEN IS SOMEBODY GONNA WAKE UP? ..............................................................                                                                                                                         freazier nutszoff                                                                                                                                                                                 ps. hell! i might even buy one myself!

Fuel filter for trikes

By Rizwan Bukhari

Today I have a question about fuel filters. Can anyone tell me what kind of a fuel filter do you use for your 912 trikes.

 

My 912 came with a glass filter and I believe my first Airborne trike (582 Bluehead) also had a similar to the picture below,

My filter looked in pretty poor condition and very dirty so I order a new one from Aircraft Spruce, I wasn't entirely thrilled with it's quality. The one on Aircraft Spruce comes with different size plastic fittings.

 

 

I read up a little bit on this particular fuel filter (above) and it seems that the mesh is much finer then what Rotax recommends and in some cases this filter was responsible for clogging the fuels flow causing engine outs. One guy had picture of his completly destroyed aircraft, the cause was clogging by this filter that starved the fuel. 

 

Which brings me to this question, what brand fitlers do you use on your trikes, does anyone know if Rotax has a preferred filter? Does anyone know of issues caused be the fuel filters.

another sad day for trikers.

By monty stone

 one in australia, one in california.            are we experiencing more trike fatals lately? is there any connection between 'transitioning' ga pilots and 'first' solo  crashes? are high performance trikes more likely to be involved? i'm not 'knocking' any particular form of trikes, like any other device, be it motorcycle, dump-truck or bicycle, in the right hands, with sufficient instruction of the correct kind they should be able to be safely opperated. is there a 'central' depositary where CORRECT accident info can be accessed in order to learn from these tragedies to maybe reduce them. we don't get much from the 'papperatzy' publishing their 'if it bleeds it leads' accounts of these events. after all, if they are relying mainly on 'eye-witness' accounts, with the close-up of an excited face of a suddenly famous 'eye-witness' who is more interested in being seen by their buddies than they are recounting an accurate account of what they saw. the ntsb and faa don't seem to be too interested in 'ultralight' accidents, especially pilot only involved. i do realize that every time i challenge gravity and take-off that this might result in 'gravity 1, monty 0, and accept that risk. passengers often don't, or didn't have the info necessary for them to assess the mortal danger of aviating. if sport pilot has done anything good, it maybe flushed the 'wide-seat' ultralights from taking up uninformed passengers on sometimes tragic flights. the house i bought in arizona sold by a lady who's husband, a ga pilot took her grandaughter up in his luscombe, showing her a loop and crashed, killing them both. she still curses him! i guess it all boils down to what happened, why it happened, and what could have prevented it, and how can we learn from it. also, brs were probably carried in these recent events, but sadly, as usual not deployed. my boring 'rants' on 'recovery' systems that rely on the pilot to deploy are too repetative to repeat, so i won't repeat them, LIKE HELL I WON'T! WHEN ARE THE CHUTE MFRS GONNA ' GET WITH IT' AND AUTOMATTICALLY DEPLOY, AS DO AIRBAGS ON AUTOS!  . quote' those that forget the past are doomed to repeat it'.'again and  again..............                                                                                                                                         ps. as the 'big boys' ntsb and faa usually refer 'ultralight' accidents to local police agencies perhaps they could 'encourage' them to ask that the closest 'trike flight instructor' be invited to help with the investigation, with, i'm sure a more accurate outcome.  pps. the use of the word-age  'trike' and 'ultralight' is simply because that's what they are perceived to be by ' non triking' earthlings! ', of course, we 'flex wing opperators' know better, don't we'? ,though, if it looks like a trike, flyes like a trike, it just might be a trike! somehow, 'flex wing pilot social' just doesn't 'cut it'. 'eliptical winged aircraft'? nah! SPITFIRE!                                                                                                                          freazier nuttszoff

Replacing Rotax 912 Fuel Pump

By Rizwan Bukhari

Hi all,

So, I may have to replace my fuel pump soon and I was doing some research, which I would like to share with you and then I have a few questions that I hope you can help with.

 

In my search for Fuel Pumps for the Rotax 912 80hp, I found two different choices on CPS

 

893-110

https://www.cps-parts.com/catalog/rtxpages/cps15-02530.php

 

And then you have 893-115

https://www.cps-parts.com/catalog/rtxpages/fuelpumpassy.php

 

Both of these are mentioned in the Rotax Service Bulliten below as viable replacement pumps.

 

http://www.airborne.com.au/images/aw_directives/SB-015-912-063ul.pdf

 

What is the benefit of the 893-115?

There is this website that explains the benefit of 893-115

 

http://rotaxnews.net/?p=673

 

And I am still confused, but what I understood is that it (893-115) is just a fuel pump by itself and you can buy the accessories that are needed for your 912 engine (because apparently there is a few different types of fuel pump out there so this fuel pump allows you to buy only the needed accessories).

 

Following are some more questions that I have for anyone who can help here, I am getting together with my A & P to replace fuel pump on mine and would like to be prepared with answers to some of the issues others have faced.

 

Fuel Pressure Issues?

I have read on many Forums that when the fuel pump was replaced, they had Fuel Pressure issues, did any of you notice that in your trikes (after replacing your fuel pump) and if so what was the fix?

 

Does Rotax reimburse you any costs for following the Service Bulletin and changing the fuel pump?

On the online forums, some people claim that they got half of the replacement costs by sending in the old fuel pump back. Most say they didn't. Does anyone know anything about it? 

 

What if there is no indication of a problem with fuel pump, should it be replaced?

Well if it is an SLSA then I guess you don't have a choice, but what if it is an Experimental? On some forums a few people said that they called Lockwood Aviation and asked them that if their existing fuel pumps were working fine and there was no indication of an issue with the fuel pump (such as leaking weep holes), should they still replace it and the Lockwood Aviation told them NOT to replace them. What is your view on it?

 

Lastly I watched this video on youtube, I believe the captions are in Italian so it is hard to understand but is this scientifically a correct demonstration of pressure issues? in this video I think they are demostrating that the old pump doesn't have enough pressure and should be replaced.

And as always thank you for helping.
