RE: Tamiya Frog - bringing it into the 21st Century
What are u planing to do?
swapping the radio gear is very simple, un plug the steering and throttle servos, un thread the areial, and remove the reciver.
then simply re fit the newer one & plug the servo's back in & re do the areial.
replacing the steering servo is very simple, remove the 4 serews holding it & remove the servo horn, the newer servos will drop straight in with no mods.
Upgrading to brushless is simple too, motor is held in with 2 screws, remove and replace with new motor. u will have to put the pinion gear on the new motor
then remove the servo for the mechanical speed controller, remove the MSC, and anything thats attached to it. then use doubble sided tape to fit the new brushless esc...
