 Posted: Thu Aug 08, 2013 9:29 am Post subject: SV: TR-1 Nose gear leg - again |
 |
|
I knew this Mark, but I have not gotten around to do that modification.
It now moves upward on my to-do list 
Thanks everyone else for sharing the experiences with the gear leg, and the
advices.
I think the way to go is to remove the leg, remove the paint and get someone
competent to re-shape or replace the bent part. Then modify the Pilot
handbook to say "stay away from grass runways"!
Regards
Hans Christian

Emne: Re: TR-1 Nose gear leg - again
The main issue with the nose gear is the main gear location!
On most trigear aircraft the main gear is placed so that about 85% to 92% of
the load is carried by the main gear and only 8% to 15% is carried by the
nose gear with a loaded aircraft. On the TR-1 with the stock main gear
location the nose gear has about 30% of the load! Twice what it should and
twice what the nose gear is designed to hold.
So if you have not done so already move your main gear forward. The
simplest way is to angle it forward by making a flox wedge shim between the
gear and the gear tunnel. Not only will this reduce the load on your nose
gear it will make takeoffs and landing much more smooth.
If your nose loads are what they should be and you land on the mains you
should have no problem with the original nose gear.
Regards,
Mark Kettering

Hello Hans,
I am not so sure I would be so quick to edit your KIS Pilot Handbook. TR-1(Lyc.O-235 powered) builder Ken P. has flown his aircraft more than 1000 hours off a grass strip in front of his house. He moved the main gear forward, extended the elevator, and has had great success. Unfortunately his daughter recently banged the nose gear and he is currently working on that and giving it a new paint job while it is down for repairs. He considered upgrading to the heavier nose gear but that would require re-engineering the firewall, a process he wants to avoid. I know there are a bunch of nose gears not being used out there somewhere but I am having trouble finding about 45 TR-1 kits. Should you be considering the heavier nose gear, Texan TR-4 builder Dennis F. recently had Lyle build a gear for him and the cost was $2800.00 U.S. dollars. The TR-1 version would probably be similar in price. Maybe I should add a few new columns to the KIS builders and owners list – Nose Gear Type, Main Gear position, and Elevator mod.

I'm sure the 2,800. price tag on the Lyle built nosegear was for a complete gear with all the attachments. All Hans needs is a bent tube of heavier gauge that can be fabricated locally.
