I have some questions about radio equipment. I currently have an HPI Nitro MT with a Futaba 2PEKA FM system. I really like the setup, and now I am in the market for a new car while keeping my truck, but I noticed on Towerhobbies it says the 2PEKA is discontinued. First question, I am curious how much better the FM system really is compared the AM's. Second, Would it be worthwhile to just buy a new receiver, crystal set, servos switch and battery pack and just use the same radio for both cars. Third, what radio setup would you recommend for the HPI RS43 SS whether it was a piece together or a completely new set.
