wheel can be mounted to motor and then assembly slid in and bolted down.
Here's the circular gap now visible in reality.
Putting a dart in there shows the hydrostatic contact principle quite clearly.
Look what happens to the hole in the foam! Not quite perfect since the rims have that chamfer.
Motors: Turnigy Multistar V-Spec 2205, 2350kv. Big brother to the stock FDL motor. Electrically a serious bit larger than the 2204 FDL motor. Rated to do over 400W continuous! We'll see how these start up. I didn't want to overkill things with a giant motor quite yet, because if we can get away with less current and less battery and less controller and less money, that's good.
Installation in flywheel: My flywheels have a bit more pot depth than a FDL wheel, motor ends up damn near hidden inside. Just the last 6mm of the stator base sticks out.
Test fitted to cage: Axial alignment looks real good BTW.
You can see how much motor stickout on the back of the flywheel there is in this image.
Threw a dart through here for an image.
Back side of a flywheel. A bit printy, and may have to be adjusted by hand a bit to bolt up completely straight and true to the rotor flange.
Hasbro HIR flywheel versus Hy-Con flywheel. Around 2mm less root diameter, and 3mm greater OD than the former.
So there it stands. I'm waiting for more ESCs and some hardware to arrive and then it's chrono time.
