Just had a customer faced a glitching problem on his 26CC Gas Plane. His whole radio system glitched very badly when the ignition system is on and started.
He thought could be his 35Mhz receiver problem and hence he changed to a 2.4Ghz. But the glitching problem still exists even though he is now on 2.4Ghz.... I can feel his frustration....
Current possible solutions he had done based on his buddies' advises are:
1) Had shifted his RX far away from the Ignition System
2) Had his ignition plug checked
Are there any more possible causes that reults in these glitches?
Sorry I am not into Gas... so can't really diagnose
Thank you all....
Derrick

I am not sure which system is he using but for some 2.4GHz system like the "Xtreme", you can't place it near any carbon fibre or metal materials .

I have used JR DSX 2.4Ghz with AR7000 on a 50cc without any glitching problems.
Maybe you can post a picture of all the wire plumbing done on the plane, then at least that could be eliminated first.
Not too sure about Sanwa, but was there a specific orientation requirement for the Sanwa Rx?

Hi Lendon,
Sometimes it's really hard to pinpoint the exact cause or source of problem, after reading what you've already done and still getting gitches from the 2.4 system it's really strange.
I'd suggest you borrow from another friend's 2.4ghz receiver and transmitter and try it out again, it may or may not have to be sanwa and then see what happens, if everything becomes ok then your 2.4 system has a problem.
But if the problem still exist with your friend's receiver and transmitter then i suspect there is a magnetic field leakage on the CDI system that is somehow transmitting/conducting to the back of the fuselage.
Gassers also vibrate a lot more than nitro engines, also check if there's any metal to metal contact which will produce RF interference. Linkage from servo to throttle must not be totally be made of metal also.
For gasser engines, just moving the receiver as far away from the C.D.I. (capacitor discharge ignition) and nicely padded with foam would resolve most if not all glitches. Hope it helps Lendon.
