I think the stock radio gear is ok for an average user. My savage is only 3 months old and i am on reciever number 3, throttle servo number 2 but still using stock steering servo. Never had a need for reverse yet. I put at least 5 tanks of fuel through my truck every day and it takes as much as i can throw at it. The reason for so many electical changes is just down to careless driving through water, snow, mud or even a river that i thought i was good enough to jump only to find out that i was not, came out clean all the same. Go with the RTR its a good package that gives you the choice to upgrade if you find that you need to.
