Hi Guys,
I know a lot of time has passed since I first posted this problem, other projects took over.
Last week I made some more tests on the Evolution 35cc interference problem.
Test 1 Connected power directly into the Rx and Ingition unit. No difference.
test 2 moved the batteries, IGN battery temporially cables tied to the UC, and Rx battery as far rearward as possible. No difference.
Test 3 Tried another Rx, only connecting the thro and one elevator. No difference.
test 4 Tried a different plug (resistive type). No differnece.

The engine runs Ok for a very short time, up to 10 seconds, then stops suddenly. Not ceased, it stops firing and stops rotation normally. This happens from idle or even third throttle, running smooth until the sudden stop.
After all of this my guess is a faulty IGN unit, which is also causing the interference. Any other suggestions?
If this seems a fair diagonisis, which system is the best/easist retro fit. The Evolution system is $229, silly price.
The CH system and rcExl units are much cheeper and from what I've read on here, well respected units.

Any assistance appreciated,
Cheers,

Peter
