In this episode of Flite Test, the team takes an ordinary T-28 Trojan, and gives it some bling! Watch as Josh and Josh show you how they custom fit retracts for this already amazing plane.   Step-by-Step Instructions:
Take note of the landing gear height before removing it.
On some of the tighter areas we couldn't get to with the cutting wheel, we used this bit...

Where did you buy the shafts for the wheels. Part with the 2 grub screws?

I'm curious if the wooden support rails need to be made out of hard balsa or a harder wood like spruce.

I did it on my T-28! I followed Flite Test's build log, and now have functioning retracts on my Parkzone Trojan. The only differences are that I kept the main gear mounting points where they are, and installed the tires outboard of the main gear struts. The result is that the tires are the same distance apart as on the stock setup (13") when extended, and are closer together - taking up more of the fuselage - when retracted. In fact, the tires are about 3/4" apart when retracted, vs the Flite Test setup. The airplane behaves just as Josh B describes. No bad tendencies. Also, the retracts I added are the smaller 10-15 size setup. The struts are the same diameter as the stock setup, so the tires go on with no modifications. I had to move the battery aft about 1 1/2" to maintain the center of gravity where ParkZone recommends.

Am I able to use normal servos (servos for ailerons elevator etc) for retracts?
