Hello everybody,
I got some radio issues on my airtronics MT4. Hopefully ou can give me some information on that problem, so let me explain:
When I finished my boat, I bought a Spektrum DX3C transmitter with its receiver, I put that in my boat and on the lake, I realised that I lost connection with the boat on less then 100ft. So I relocated the antenna outside the hull, and went testing: the range was bit better but not that what I expected. At that moment I was using a 4 cell 2000mAh NIMH battery pack on the receiver.
After talking to some people I sold my Spektrum and got an Airtronics MT4. With this transmitter the range was way better, but I still lost connection at moments. I changed the receivers battery pack to 1600mAh 5 cell NIMH, but still lost connection. I noticed also that I forgot to turn on the failsafe on the transmitter, and after cogitating about that problem, I realised that if I had really lost connection due to too much distance, the boat should have continued at the same speed without putting the ESC's to neutral position. But in my case the boat stopped, and I had to approach the boat to reconnection. The servo I use is a Savox 1251MG, and my boat is a SAW catamaran which goes at about 95 mph.
So the question I'm asking is, is the connection loss due to high distance (and what can I do to improve it? I'm expecting a range of >500 meters) or is the servo consuming so much power that the receiver is switching off?
Sorry for my bad english^^ I'm not a native english speaker
Thanks, Claude

. I have always maintained that on the GT3B you do have a rough servo action, the resolution is low and Latency is slow, those are plain facts. Others would say that the radio had failed on them, I have no reason to NOT believe them, in my case it worked everytime. But I would not put that radio in a $2000 boat. Human nature, I like to think I get what I paid for, whether it is true or not in this case.
). I love your boat! I ask only to satisfy my own curiosity: In the picture you were using a MR200? Was that the receiver giving you trouble? You should have been ok with one antenna running outside ( per Spektrum 's recommendation= longer one out and the shorter one horizontal inside).
