ladies and gents, i have positive results that the glitching was caused by.. (drum roll please).. the SWITCH. after testing things one at a time i got to unpluging the switch and plugging the battery directly into the rx, and the glitching was vanquished. thanks for all helpDerek O'B

I think that it is worth pointing out that the switch is one of the weakest links , if not the weakest , in our whole systems . The biggest killer of switches is vibration , yet most switches get hard mounted in the helis side frames - the only component in the entire radio system to get no vibration dampening . This is largerly the fault of the helis manufacturers for providing the switch mountings the way that they do , but I always mount my switches on 4mm gyro tape . On my Raptor , I fitted a rear servo mount for the tail servo , this then left the original tail servo position for the switch fitted between two layers of gyro tape , well protected from vibration .At the end of the day , it gets dark .

its not the switch. some how the problem was masked when i swapped switches on the bench, but then tried to do a run up and got the glitching again. back to the think tank.Derek O'B

Unplug everything and try it one by one.

You might also want to check your battery. It could have a bad joint under the shrink wrap.

I just helped a buddy with his glitching problem. His glitching was caused by a bad battery. It showed over 5 volts, but he cycled it and it would only take and charge around 600 mah on his Triton. It is a GP3300 sub c pack that was about a year old. He replaced it with a 2000 AA pack for testing and it flew flawless. DOC

I solved an intermittant glitch in the air by replacing the receiver
and crystal. This may not be your problem.

I origionally thought it was a voltage problem and have some
observations that may help.

The system voltage is lowest in the air. It's much lower than
if you weigh the heli down and ground test moving the servos
constantly. The digital tail servo appears to draw more current in the
air that if you just swing it back and forth on the ground.
Maybe I can't reverse it as fast as the gyro, I don't know.

If you use one of those voltwatch units and have to use a "Y" cable,
do not put it in the battery feed. There is a voltage drop across the
cable. Put the cable in the gyro channel which doesn't draw current.

Don't fold the antenna back on itself to get it to look nice with the
antenna tube. Go for a straigt shot to the tail if that's where you're
going. You're probably not doing this with the heli you have.

For a long shot, I'd weigh it down. Get soneone to help with an
AM radio with a loud speaker or headphones. Tune to an unused channel
and see if you have something mechanical producing static. It's
a Cable TV thing...

pulled the rx foam off and was about to unplug some servo lead so i could check each servo individually and without the engine running i got a glitch. what a discovery. the cause is that if i press down or squeeze the rx i get a glitch. im pretty sure i have the problem nailed this time. i figure when the engine was running it caused whatever happens when i squeeze the rx to occur. its late and i have to get up early for work so ill have to wait to 100% confirm this is the problem, but im sure its it.Derek O'B

Vibration aggravating a short in the RX maybe? I guess this is PPM you are using. If you have another RX and xtal that would be the next thing i tried.
Woohooo!! What do i win?

you get to tell people you were the one who knew the fix to my problem
since swaping rx's i get better range checks, and have burned 5 tanks of fuel that confirm everythings good again.
