Thank you Kim

Here is a vid using a drone prop for more thrust allowing some fun flying with
the throttle. The TD .010 can make some good power for such a small displacement.

Lil Speedy TD .010 / Test Flight 3x2E Green Drone Prop
Best pass cross wind 32,792 rpm / 62 mph / per prop calc.
Solid pull better loops and faster turns great prop with a throttle.
Down wind passes:
33,941rpm / 64 mph - per 2in pitch / and calc slip.
Didn't quite get on the sweet spot with the needle tad rich very fine
line to have it singing steady. Breezy day the lil wonder held it's own.

Just incredible that little wonder accelerating and decelerating in flight !! ... I like the .010 with speed regulator ring! Clapping

With the lower skirt ground off you still have enough cylinder diameter like a TD .049
to catch the crank case see photos. I covered the threads with tape then filed off the
skirt with steady care. Note the baked on castor oil over time this helps for a tighter
seal and lower idle so let it collect. I put a groove around the sleeve then used piano
wire loop smaller in dia. of the sleeve it snapped into to the groove and holds well.
Small arm extension with another small wire loop with tubing inserted for a slop free
use with the throttle push rod. It's easy to do just takes time. I used reading glasses
to improve my vision during the fabrication as these are very small parts.

If you can source a suitable C clip the effort mimics the familiar for a nice clean setup.
