I have 10 models in my JR 8103 transmitter. Imagine 10 transmitters in the shop all on chargers not to mention the cost.
For the amount of money your talking about you will only get the basic non computer, 4 channel radio.
If you want to buy complete radios rather then just flight packs because there is so little difference in cost you can always sell the transmitters at the field as buddy boxes for 30 bucks each.
We get new students all the time and I always recommend they get their own buddy box. It speeds up training and is easier on the instructor.
