DA100 Does this look right to you?
I have a Hangar 9 Extra with a DA100 that I cannot get a good range test on. I have been through all of my radio components and can find nothing. I pulled the plug wires off and noticed that it does not appear that the wire in the plug boot would be touching the end of the spark plug when it is hooked up. I have attached a pic of the inside of the plug boot and you can see the wire way up in there but I don't see how it could be touching the end of the plug..Is this correct for a Da or am I missing something? Thanks. Rusty

Hey Rusty,
I have a DA-100 that I have yet to run, but my plug wires look exactly like yours. I would assume that they are ok....I did notice that you really have to push the caps on rather hard to make them stay on the plugs. Phil

The plug boot looks fine. If the plug boot slips off the plug while the engine is running, the ignition gets fried.
A poor range check could have several causes. Are your ignition components (including battery and switch) at least 12 inches away from all receiver components (batteries, switches, servo leads)? Have you eliminated all sources of metal to metal vibration - metal clevises on metal threads need locknuts. Any metal parts touching other metal parts have to be tight - any wiggle room can cause interference.

I just inspected mine. I think you are right. there is no way that boot goes on far enough to make contact with that little piece of metal. wow it's way up there isn't it!! It seems like there would be arcing...

RE: DA100 Does this look right to you?
I unplugged all of the servos except the thottle servo and it still goes nuts. I then unplugged the throttle servo and plugged in one elevator for a reference and it still went nuts. I am using an optic isolator on the ignition and no components are within 12 inches of the radio. I also tried 2 recievers to no avail. Could it be the ignition itself. Is there anyway to test it?

Check the plugs and wires with an ohm meter. You may have an open inside a plug or wire. Make sure the resistance is correct.
