I used the DuBro gear on my conversion as well. It really tracks well since it has some give to it and I've managed to test its strength a couple of times and, even in the cold, it just springs back to shape and comes back for more.

Just an FYI and this will probably start another prop war but oh well.
On my LT-40, I have replaced the main gear with the Dubro Figerlass gear and the nose gear with the Fults dual strut model. This gave me another 3 inches of prop clearance.
Today, our club had it's Fun Fly and just for giggles I had several 12.25X3.75 APC 3D props ready so I screwed one onto the OS46AX in my LT-40 and all I can say is boy did this wake that plane up. Plus with the different main and nose gear I still had 3/4 inch of prop clearnace.
Oh and just so you know the engine is still brand new and only has 8 flights on it after today and it is still in the process of being leaned out from breakin settings. The plane has had all of the control surfaces sealed on the underside which also made large handling improvements before the prop was changed
Please understand these are not exact measurements by any stretch on the imagination but just generalized comparisons.[sm=wink.gif]
Intial prop was an 11x5, now it has the APC prop.
1. Shortened taken run by at least half the distance.
2. After the plane broke free of the ground I was able to pull vertical for what looked like about 500 feet until the airframe finally overloaded the prop and the plane slipped into a power on stall.
3. All maneuvers (slow rolls, rolls, loops, cubans, immellmanns, Split S, reverse cubans and inverted flight) improved the wow factor quite a bit.
4. Level flight at full power on a timed 300 foot run improved by 4 - 5 seconds.
Yes, I may be overpowering the airframe but with smart throttle management, this should not be much of a problem.
All I can say is WOW [X(]...what a difference in performance.
Rant over....
