Default 1970s Midwest Clipped Wing Cub conversion

1970s Midwest Clipped Wing Cub conversion
As part of my 1970's vintage haul (3 planes, see http://www.rcgroups.com/forums/showthread.php?t=1741528) I snagged a gear-gutted (except for the engine) Midwest Livewire "T-Craft" clipped wing cub.

Just finished removing the gas engine and fuel tank and started the conversion.

So far I have the motor mounted (GForce G40 700KV), I used the existing engine mount T-nuts to mount a thick AL plate that is drilled and tapped for 4 10-24 screws, jam-nuts where the screws enter the plate, and just a nut on each side of the motor's normal X-mount. Between bending the screws one at a time and adjusting the nuts I can adjust both the propshaft angle and get the propshaft to exit through the minimal hole in the cowl.

I discovered with the motor and cowl in place the CG is just about perfect without the lead plate that was used when it was a gas plane if I can get the 4S battery all the way forwards.

BTW, the manual says to check the CG with the wing OFF- never saw that before...

I refuse to pull the wing to change the battery (especially as I can transport it with the wing on), and the design of the plane necessitates a side hatch unless I just strap the battery underneath.

So, last night I cut a hatch in the left side of the fuse, I should have good access room under the wing if I tip it up onto the nose.

I have an RX, still trying to line up a used 100A ESC (on the cheap, I am) and a BEC.

Ask me why your DX5e is doomed... and how to fix it.
