Default Glitching Issues

I have the easy star with the Airtronics VG6000 6 channel computer radio, airtonics dual conversion mini receiver and the airtronics 20 amp speed control. I have been experiencing bad glitching problems. I only installed the 2 capacitors that came with the kit and I will try adding 2 more. Are there any tips anyone would like to share. I will try anything to help make this better. Distance doesn't seem to matter....sometimes its close and sometimes not. Also, motor speed doesn't matter....it does seem to happen more at full throttle but it has happened at half throttle as well.

Thanks,
Ryan Parks

Try taking the reciever out side of the fuselage away from the ESC and all the high current wiring. Also if you have a spare transmitter and rec. try them. Worth a try anyways.

First lets confirm that it's glitching your dealing with, are your servo's twitching when this happens or is it just your motor acting up
What motor and batt are you using
Here are some basics to help with glitching, first add 2 more capps to the motor, make sure none of the wire from the cap on the + side post touch the motor can, you can solder the wire on the other side of the cap to the can I found the best set up for the caps is to have 1 cap per post and other end to the can then take 2 across post to post + to - , make sure all servo wiring are seperated and not crossing each other, make sure antenna wire is not being crossed by the servo wires or any control rods, also make sure the control rods aren't touching while moving, keep the ESC as far from the motor as possible, Also be aware of where you operate the plane, some areas are just prone to cause glitching, been there done that. Good Luck with it

what i did on 2 diff planes that i was getting glitch problems with is.... i twisted every wire that was in the plane. example; takes your servo wires and twist them like your winding up a rubber band (not to were it knots). do that to every wire in the plane, except the antenna, keep that away from the other wires. this worked on mine.

This is going to sound absolutely stupid - but check and make sure your receiver crystal is a real dual-conversion crystal and not a single. I had a Futaba 8-channel that had the wrong crystal installed, and it glitched exactly like you're describing. I fly in a very hi-interference area, so a dual-conversion rx is an absolute must.

Spiced, I think the servo and Rx wires were twisted like you say on a Futaba radio set that I had many years ago. I will have to try this idea the next time I have a glitch problem.
I had a glitch problem with a previously stable plane set up awhile back. (This was a well known name brand unit) I just could not get it to stop glitching while running tests in my garage. I finally found that the floresent lighting was causing the problem. Boy did I feel stupid! Some people use a cheap DC powered AM/FM radio as a test for interference before they fly. (I plan on trying this myself in the near future) I also had a case which was only solved by switching the Tx to a known good name brand unit. Beware of inexpensive RTF systems as they sometimes have recvr, servo, and or ant. wires zip tied to the batt/motor wires. I have even seen ant wires wrapped around steel control rods, etc. (I try to run all ant. wires outside of the fus. as much as possible.)
It is also a good idea to wear a wrist ground strap while working with electronics such as servos, Tx, Rx, antennas, etc. I have seen more than a few PC motherboards ruined by elec. static discharge. I rub the carpet and cloth seat covers in my vehicles and work shop with a dryer sheet so as to reduce static elec. build up. This can help reduce the possible damage to your electronic devices by ESD.
