Purple Bird,
The instructions that came with the motor should be your bible on how to break it in. Different motors have different break-in procedures, and since you didn't list the type of motor it was there is no way we can tell you how to do it. If you follow the instructions for break-in that came with the motor you can't go wrong. One piece of advice that is pretty much constant for all motors is that after you break it in, keep it running a couple of click rich and the motor will last a long time.

As far as the hole in the covering goes, do as posted above and use a piece of packing tape or scotch tape to patch the hole. Don't worry about the dings and dents, this is a trainer and it's going to get beat up as you learn. Just patch the boo-boos and keep flying!!

The last piece of advice I can offer is don't be afraid to ask questions. Either of your instructor or here on RCU, the only dumb question is the one you don't ask.

Hope this helps

Ken
