Default Reciever cutting out

I have a scarab kv 38 with a home lite 33cc gas engine, older version. I was running running with futaba magnum junior radio and am reciever with no issues. I converted to a fly sky gt3b 2.4 ghz and high torque servos,using a 6.6 Life battery pack. Everything works fine until you start engine. Servos go haywire then reciever becomes unbound. Have to shut down and rebind reciever then works fine until you start motor. Can anyone help with this issue

Hey it's your first post. Have fun. Sounds like you have a bad receiver. I have two boating buds. 1 uses gt3. Works great. 2 uses futaba fm. Works perfect. I was using futaba fm. Worked perfect. I am using spectrum now with non marine receivers. Range is super short. Just got Spektrum marine receiver . Have not tried. https://m.youtube.com/watch?v=EZXRDgwVX1w

As mentioned above, almost certainly just a bad receiver - not unusual with the Flysky stuff.

I my experience FlySky is some hit or miss stuff, usually miss. You get what you pay for, and that seems to go double in this hobby from my experience. I realize that this hobby can be expensive and one trys to save where they can, but what if your receiver cuts out as your boat is heading toward a concrete lake or river barrier at top speed and then you have a total loss. Cheaper is usually more expensive if you get my drift.

Take that fly sky radio out of there before you have serious issues.
Been at this a while and the only 2.4 radio that seems to work well are the Tactic pistol grip TTX 300
I have the older version in both my boats.
They have a built in fail safe so if the boat goes out of range or something stupid happens it goes to park mode.
Please don't run that fly sky radio they are not good for boats and either are spektrum.
The old radio you had will work well also.
I used to use the Jr synthesized radios in boats with no issues.

All the guys I used to race with used either a JR synthesized radio or futaba Fasst. You can also try a resistor spark plug.

Wink radio noise

Make sure you are using a resistor type spark plug and put a grounded braided shield over the sparK plug wire. good luck.

I'm surprised that you managed to get away with an AM radio system for so long! Usually gas engines don't like them.
Spend the money and get a decent radio in it. Futaba has them relatively cheap now. I just picked up a Futaba 3-channel that's pretty well loaded for under $115.00 to my door.
The problem with Fly Sky and Spektrum RX's is that the tiny circuit boards are thin and prone to cracking very easily. You push in a connector too hard and there it goes.
