Derek, You'll be very happy with the 3PJS if you decide to do it. Here's some of the benefits:
1. PCM offers failsafe feature which is awesome for nitro racing, servos go to a preset position if another transmitter on the same channel turns on while you're on the stand!
2. Super clean glitch-free PCM signal.
3. 8 AA's last over 10 hours.
I've had the same radio for almost 4 years, it's great.
