Do a good range check with the ECU unplugged! With your receiver / airplane about 3 feet above the ground on an wood / plastic stand You should be able to walk about 100 paces or about 300 feet, in any case not less than 225 feet. And yes that is with the antenna removed on the 10X! If you want to have the antenna screwed in place fully collapsed then your looking at about 200 paces or 600 plus feet! Turn the transmitter in all directions and see no fail-safes.

If you can't get this kind of baseline range check send the junk receiver and transmitter module in for match tuning & alignment. Ask them to not send it back until it will range check at least the 300 / 600 feet. This crap about 50 or 100 feet is just that... radio manufactures and more importantly resellers advertise those low distances because.... they want fewer returns for warranty repair!! Beg my pardon but I call um like I see um...

OK, then do the same test with ECU plugged in..... what distances do you get?

Then start the turbine and run-up to full power.... do the same test... never but never fly if the degradation is more than about 25% in distance.... use a whip antenna move the fuel pump farther away from any receiver wiring or antenna.... until you can get no more than a 25% degradation in range from your established baseline...

If you really want to get serious do the range check with the transmitter antenna fully extended. The normal best baseline will be about 1/2 mile! Yep thats way farther than you can see to fly! The average radio / RF link will get at least 2000 feet or slightly less than 4 tens of a mile. In no case should you fly if this full extended range check at full power checks out at less than about 1600 feet!
