RE: rx choice
G'day
In Australia we fly on 36 megs but things are rapidly moving to 2.4 gig. I still use three 36 meg radios (all JR) but my receivers are mostly Hitec. I love the Electron 6. It is dual conversion and as result I have never had interference problems with my several Electron 6 receivers. They work well in quite large planes (I have one in a Kadet Senior) and also is quite small planes (I have recently removed one from a half size Dalaire Sportster (1.5 cc diesel engine)). I have several others in other models but I am not sure which models they are in. I also have a number of Hitec 8 channel receivers which are larger but which are also excellent receivers in models where the extra channels are needed and the large size is not a problem.
I have used Futaba receivers and had no problems with them either but I have had some problems with JR receivers. They work fine when they are new but they are not very tolerant to crash damage and need to be extremely well protected. The main problem with them is that they have a main circuit board with a small "daughter board" soldered at right angles to the main board. Any sort of trauma can cause the daughter board to bend and fracture the solder connections. The tracks are extremely fine and they can sometimes be repaired but sometimes the tracks lift and repair is not safe.
Go Hitec and you will be happy.
I also use mostly Hitec Servos too. Excellent range and extremely reliable.
