Well, I had to slightly adjust my thrust angle after putting in the 1400Kv motor. I have been flying intermittently due to adverse weather. I recently added new tires to the plane, and these look and work very well.

However, during some weekend rolloff runs on TO with this plane, the yaw to the left was VERY significant. [I usually hand launch on the grassy field I fly at]

I used two thin ~0.4mm washers used often in landing gear as bearing shims to space the motor mount from the firewall on one side. Two went on the port (left) side of the firewall to adjust the angle slightly more starboard (right) and slightly up.

I flew the plane twice yesterday, and it tracks better in loops, and does not have the yaw/roll issue that seemed to be signficant [but not unmanageable]. I have yet to do an asphalt run with the new thrust setup, but it looks good so far.

The Super Decathlon BL got few new wheels to help in taller grass... so far they work fine. Main reason for retrofit is looks and functionailty - a better fit on the gear, with slightly narrower profile.

First pic: before, with Dubro Micro lite 1.75" wheels.
Subsequent pics: shots of new wheels, stock gear form my newly-aquired Pitts 12 15e by E-flite. These are just about 1.8" dia.

Well, I am consturcting a summer project: the Pitts 12 15e by E-flite.

I plan to use 12x7x3 and 12x6x3 MAS props, with a 2.5" spinner. Will be running a RC Timer 3648-5 900kV 770W motor, probably set it up for 3S service for now.

I have a 60A Eflite Pro ESC, and will be getting a AR600 fullrange RX.

Looking forward to building this plane!

Stay tuned...

I have had several PMs regarding my micro champ gear installation in more detail, so I have included some photos for those wanting them - apparently no pix in PMs are allowed.

This combination of replacement gear rolls WAY better than stock, and allows for much better grassy landing and takeoffs!

Mains are Dubro 1.23" sport wheels, [DUB123MS], tail is 3/8" micro Dubro tail wheel [DUB38MTW]; for those wanting more clearance, 1/2" are also available [DUB12MTW].
