Spiral diving claims another victim

By Rizwan Bukhari

There is a lively discussion on www.alltrikes.com . Apparently an Airborne crashed killing the pilot and the passenger. This is a different Airborne than the one we heard about crashing recently.

According to the dicussion on Alltrikes.com the pilot spiraled into the ground from 500 feet.

 

This is very tragic and sad. My condolences to the family and friends. I think, going forward spiral recovery should be made part of PTS manuvers.

Trike Shimmying at landing

By Rizwan Bukhari

I went with my friend for a flight today, I fly a Northwing Navajo with HKS 700e. We did a few touch and gos, on two of the landings we felt a significant shimmy.

Now on my trike, I already have a dampner, I am tyring to figure out what could have caused the shimming, the only thing I can think is that my tundra tires were a bit low on air and also the second landing was done probably a bit faster, with about 6 mile cross wind.

Has anyone who owns a Navajo trike exprienced this? sometimes I think due to a four stroke engine, maybe the rear part of the trike already is heavy to begin with, add a 215 pound passenger and slightly deflated tire, coupled with a cross wind landing and all of the above could have contributed to the shimmy.

The first time my speed during the shimmying was around 20s or so, so I punched the throttle and took off again, the second time I applied the brake and that kind of stopped the shimmying.

None the less, I would like your input. For those of you who have tundra tires, what is the pressure you keep in those tires?

I spoke to trike pilot friend, he recommended to check my axles and rear gear assembly, for any cracks or damage and also to land slow and keep the nose wheel up as long as possible at landing. I couldn't find any damage on the trike, so I was hoping for anyone else who has experienced the same shimmying, that could shed some light on this topic and share their solution.

Oil For 582 Rotax

By Dick Hall
About a year ago Paul Hamiliton gave recommendations for 2 stroke oils.  A clip from the article is below:

Use a good well know reliable oil. Many engine failures are from some new oil mixture, some magic new oil or someone trying to save money on cheap oil. I recommend three types of oil. The most reliable over history is the Pennzoil - 2-cycle Air-Cooled Engine Oil. This has been tested and is proven to be the best dinosaur oil. This is the preferred oil if you are in a humid area and/or go for longer periods without running your engine. Pennzoil - 2-cycle Air-Cooled Engine Oil produces the least amount of carbon deposits (for dinosaur oil) and keeps oil on internal components with so they do not corrode when sitting in a humid environment  for longer periods without being run.

The new Aero Shell Sport PLUS 2 has been recently developed specifically for Rotax 2 stroke engines and has been tested and provides the same protection as the Penzoil. This is another recommended viable option.


I just installed Oil injection on my low hour 582 grayhead and wanted recommendations for 2 stroke oil which I got from the above blog.  The only problem is this.  Aero Shell Plus 2 is no longer made and is discontinued according to the supplier.  As is Pennzoil 2 Cycle air cooled oil.  The only replacement is Pennzoil Outdoor Multipurpose 2 Stroke oil. See discription below: 

Pennzoil® Premium Outboard and Multi-Purpose 2-Cycle Engine Oil is a high-performance 2-cycle engine oil meeting or exceeding the warranty requirements of all leading manufacturers of 2-cycle products including chain saws, lawn mowers, motorcycles and string trimmers, as well as outboard engines made by: Johnson/Evinrude, Mercury Marine, Yamaha, Suzuki, Nissan, Force/US Marine, Mariner, Sears and all other manufacturers requiring NMMA TC-W3® oil.

Any opinions on this using this oil would be appreciated.  It seems there isn't much of any other choices other than the oils found in the Walmart aisle.  It appears that manufacturers like Shell, Pennzoil and Castrol don't have enough of a market to justify producing a specialized oil such as Aero Shell Plus 2, as they only produced this for a little over a year.  Comments are welcomed

Nothing like being a pilot

By Abid Farooqui
We take a lot of things for granted in our lives. People here who fly, take flying for granted. We should always remember what a select group of individuals we are to break the bounds of gravity just because we can and for having fun.

Find the time to cherish things you love and find the time to fly, safely.

'it's a little airyplane'

By monty stone

i frequently trailer my trike, and often, inquisitive earthlings ask 'what is it'?  well, trike don,t cut it. their little kiddie has a trike, and it don't fly!  using fed-speak 'flex-wing' only makes it seem dangerous! so, i usually tell 'em 'it's a little airyplane', which seems to satisfy the average proleteriat, but one little snot-nosed pre-adolescent asked 'who flyes it for you? obviously his part-formed logic-center (centre to my anglo buds)  couldn't equate how a pot-belly, bald, funny-talking octogenerian could possibly master this fearsome array of tubes and wires, when i admitted " i do" he walked away muttering 'lying old coot! another time when i was busy 'fettling' my trike a feminine  voice behind me said  "it's bigger than i expected". well! it's been a LONG time, if ever, that i,ve heard similar words! the voice belonged to a little old lady out walking her dog, which had not stuffed its snout into my crotch, nor had 'it' tried to hump my leg, so i didn't know she was there. she lived locally and said she enjoyed watching me fly my 'little airyplane' and that it 'looked like fun'. i agreed, it was fun 'flying my little airyplane'.. ps. for the non-anglophiles 'fettling' refers to tightening the swathes of baleing wire seemingly applied to those parts most likely to fall off, also wrapping another layer of duct-tape to any weather ravedged tape already applied to cover something we would rather not see any more, etc.  pps. some years ago  we 'trike drivers' had a lively discussion as to what it is that we fly. hardly anyone suggested 'flex-wing', but that's what we're stuck with. so be it.  but i still like to think i fly 'a little airyplane' it's more fun that way.  ppps i remember when SEX was fun and FLYING was dangerous! but, now.....                       monty

Any Trike Pilots that also fly PPGs Powered Paragliders

By Rizwan Bukhari

Hi,

Is there any pilots on this forum that also fly PPGs? I have been thinking about exploring PPG flying in 2015.

I have done some research on it, my biggest fear like most new pilots would be the wing collapsing. Personally, I think this can be a great form of aviation. My inspiration to explore this field came from reading the book, "Running into the sky by Chris Wolf".

If there is anyone who was/is a PPG  pilot then I would like to hear your story and experiences and recommendations.

Regards,

Rizzy

Books or movies on trike flying

By Rizwan Bukhari
Hi all,

I just got done with my final Securities exam, so now I have a lot of free time to read.

I would like to know if there is any book or videos that you can recommend, related to flying and flying adventures, they don't necessarily have to be about trike flying but any kind of flying related interesting book or video that you enjoyed or it inspired you.

I would appreciate your recommendations.

Regards,

New Delta Jet 2 Performs!

By Todd Halver

We have had many inquiries on the performance of the NEW Delta Jet 2 with the Cheval 12.4M wing.  I thought I would give some real life results from a recent flight.

This DJ2 is equipped with a Rotax 912ULS 100hp and the tundra tire option and has a useful load of 540 lbs. This flight was one up with me at 240lbs, full fuel (14 gallons), density altitude 1,700, temperature 24, dew point 20.  Keep in mind that Delta Jet 2 has a proper static port to report airspeed that is much more accurate than some set-ups.  This DJ2 is equipped with the new Sterna three blade composite propeller.

  • Take off with trim in full slow position delivered 1150 fpm climb at 63 mph turning 5325 rpm
  • With the DJ2 trimmed for full fast and turning 5640 rpms my level cruise speed was 102 mph
  • At full fast trim and bar pulled into my gut speed topped 112 mph at 5700 rpm
  • When set at full slow cruise I was able to settle in at 65-67 mph
  • Trimmed for medium cruise speed delivered 82 mph at 4650 rpm
  • Powering up to 5,000 rpm put my cruise at 89 mph

The Cheval 12.4 is a light in roll and great tracking wing.  We use lexan winglets and in testing I found I gained 3 mph speed with the winglets than without and improved turning performance.   The wing is stable and delivers a very slow stall speed.  In fact, power off stalls in level flight yield no buffeting and the nose just leans over into a gentle descent.  The full stall position would actually be at a point beyond the compression strut.

Having trained in an Airborne XT, flown and owned both a Tanarg and a Revo for a number of years, I have to say the DJ2 has exceeded my expectations both in performance and true value.

What GPS to buy

By Rizwan Bukhari

Hi,

I am in the market to buy a new GPS for my trike and I would like your input. Currently I have the old Garmin GPS iii. What GPS do you use, why do you use it and how much did it run you?

Thanks for your help.
