Hi

I tested run the RCS 180 with a fully charged 2100 Mah Nimh battery today. Same result: the engine is very difficult to start. Some time, smoke will come out of the back of the carb. If I am lucky and have it started, it will run with unstable RPM, and eventually quit after let idle for 10-20 seconds.

The engine is bought new, has never been inolved in a crash and has this problem after first gallon of fuel went through. It has been sent back to RCShocase twice. Before that, RCShowcas has nicely sent me 2 carbs and 1 ignition module to test. The problem persists.

Any suggestion is greatly appreciated.

Mike at RCS, can you please do something about the engine? I really do not want to waste any time on it!

test run conditions:

airframe: Gas Pattern (RCM plan)
mount: inverted
fuel: 32:1
prop: Menz 18X8
ignition batteries tested: 2100mah NIMH and Sanyo 1100mah nicad
muffler: KS muffler for 30cc engine
needle settings: RCS default (Low 1.0 out, high 1.5 out)

The problem is finally resolved. Thanks Mike!

Enquiring minds want to know what was wrong...

Do not know. But Mike has agreed for an engine exchange. Excellent service from RCS! --qc
