Hi Steve,

Here are some answers. Hope this helps!

1. I would start with whatever the original thrustlines were. I built my Partner to the nose ring and have had to make no changes.

2. Deans Ultra Connector. I solder the motor directly to the speed controller and then have connectors between the ESC and batteries.

3. The motors and controllers can be very spotty. I have had a C50 14XL Acro and the 90 amp controller on order for over a month. Thunderpower batteries have been pretty good. I've never waited over two weeks for them. They are in the middle of some changes so availability may be a little slow.

I have 170 flights on the partner now and I still love it. Haven't worn out a servo pot yet!
