Status: offline 		Thanks for the tip, but I already have too little clearance on the prop tips
I have installed my PIC circuit and a 1S 4000 mAh battery, and two heli glow plug connectors.
It is effectively a Y-Lead on the throttle output, and anything much below 1/4 throttle, the glow plugs come on.
Haven't had a flame out since. And I don't need Glow Drivers
The carburator is now giving problems, two flights, and the diaphragm valves start curling up.
Leave the engine alone for two weeks, and they lie as flat as new.
I run the engine completely dry after the last flight of the day, maybe I should do that after every flight ?
Going to a local Walbro supplier tomorrow, see what he has in the line of alcohol resistant kits.

And to give credit where credit's due, a very easy starting engine, and actually does sound different from a single.
And much less vibration !

Running the carb dry  will accelerate the rubber hardening, but running coleman fuel (or equivalent) after a flight day will preserve the carb quite well.

Status: offline 		Well, just an update.
I found out the hard way that this engine is at it's happiest with 20%castor, 80 %methanol.
NO nitro !
I'm still using the low throttle on board glow driver, and on startup keep my hand on the RH cylinder, to feel when it fires up, and starts giving power.
Once hot and running, this motor pulls a Drastik 120 vertical.
Main needle almost fully screwed out, low needle set up for a slightly rich idle.
Last flight of the day, I pull the fuel tube, and let the engine run dry.
This motor isn't too particular about glow plug types.
Prime it 6 turns with fully open throttle, close to idle, pretty much starts on first or second flip.
Only flame-out I had, was when the fuel tank was empty !

Sorry! But they are not! And that's why MVVS stopped manufacturing them after a very short period.

Some have great success. Not for the beginner though.
