RE: Radio upgrade?
This is just my 2 cents, but if you do upgrade to a fm radio purchase one that will work with spektrum. The srx is a great buy.. I picked one up at my LHS for 105.00 after taxes with the mini receiver. I also upgraded it to dsm with the spektrum module for another 149.00.. so for around 260.00 (give or take) you can have a great radio set up. Way better than the model horizon is offering with the spektrum built in and for around the same price..
