I've seen Tower trainers at the club. The instructors say it is a good trainer.

Airtronics makes perfectly good radios. They are not really popular around our club, but the people who have them like them If you buy the Airtronics radio, and an Airtronics trainer cord, you can buddy box with your friend. As far as I know, Airtronics can only buddy box with Airtronics. If your springtime instructor does not have Airtronics, or the club doesn't have an Airtronics trainer box, you'll have to buy an Airtronics trainer box between now and spring. The box with cord is $29.99.

The cord alone is $11.99 I'd spend the $30, that way you'll always be ready for training with anyone who's qualified and willing to help you.

Don't worry about the non-BB servos. They'll work fine.

The Thunder Tiger engine does not include a glow plug. The OS #8 is a good choice. Other plugs may also work very well. My brother tried several different plugs in his and the OS works best for him. I use the Fox Miracle plug in my Thunder Tiger 61 and it works good for me.

I agree with the Master Airscrew nylon prop recommendation. I am still a student and have broken a bunch of APC props and a few wooden ones. The black nylon props have enough flex to survive a 'nose low' landing.

Definitely find a local source for fuel. In Dallas, I can buy 10% fuel for as little as $8.95 per gallon.
