i have today flown my boomerang on futaba 2.4 for the first time no problems what so ever, i know there are loads of people that say this and that and i called some well know jet flyers and got told that futaba 2.4 was no good but i cannot fault it so far.
just because some people have a bad experience with it they blame the radio but you never see thier install job, follow the instructions and which ever brand you choose will be fine i am sure.
