I have just finished my tower trainer! All radio gear has been installed and everything seems to be working correctly. All I have left to do is find the CG and place some thread sealer on my motor mount bolts. I am getting ready to pack up and go to my uncles house so he can show me how to fire up my engine and run it properly, I'm wanting to know if there is anything else I should do to my model to complete it. Thanks!

Set the throws?
make sure everything is secure.
I am sure your uncle will go over it.

i remember my first airplane and how proud i was, when you first see the engine fire up, always gave me goose bumps good luck.

I'm assuming that your uncle is an experienced R/C pilot. Have him give a GOOD lookover before flying. Make sure your batteries are FULLY charged. If it is a new set go ahead and charge them for 24 hours the night before flying. This will make sure they are fully charged for the first time. Charge time later will depend on the batteries and charger used.

Have a good time and take sun glasses.
