go to a shop and look the radios over, if wont mean crap if its a great deal and it has all that you want if if doesnt feel right in your hand. sounds dumb, but its the truth. check out used classifieds for folks gettin rid of radios all the time. might score somethin u thought u couldnt.

servos, considerin u said u had an OFNA RTR, i'm guessin ur 1/8bug or trug. u'll be spendin a couple hundred bux there if your gonna go thru the time and effort to change them out. honestly hold off on ur T/B servo (keep ur old steering unit as a backup), and change your steering servo for a faster/stronger unit than what came with the car. JRs have 3yr warranties if that matters to you, but futaba and AR make the best units. hitec might look attractive in price sometimes (honestly not so much anymore), but stay to the 3 brands listed above. good torque and good spd and u'll be fine. honestly if you just wanna upgrade your radio to get on 2.4 and not worry bout crystals, then take care of that and wait on the servos. idk where your from but if your season ends around sept/oct, perhaps wait til next yr to address those things and any other problem areas that have cropped up. i'll take a shot and say that during school ur prolly not workin as much if at all, so there's less cheese (to be 16 or so and pay 4/gal eek).

good luck, enjoy the hobby
