That is a beauty. In order to facilitate clearance in Pusher configuration, I moved the little brass thrust washer to add clearance for the can. It moves the mags and all about 3/4mm forward and allows it to clear nicely. it's probably about the same place the can ends up when the play in the shaft is tugged forward in a tractor configuration. So, now there is clearance and the slots are pretty darn full. KV is ideally going to be around 2500 for this little plane. The plane is very nearly complete and flight test will be tomorrow. He needs a new esc as his ancient jeti 18 stutters this motor. My Phoenix 10 ran it up as smooth as can be from first click of throttle to full. It would overload that ESC in the air big time though, so a TB 18 will probably be what does the trick. we'll get that in the AM and try it out.
