Boex:

Dispite all the great advice in this thread, my 2300 would dead stick suddenly at a throttle change. It would happen anywhere in the flight.

I tuned the Dickens out of the engine, tried several plugs (F included), variations of fuel (5,10,15) and run gallons of it, variations of props (16,15,18....), variations of fuel tubing, Perry Carb, Perry pump, completly new fuel system and I am using the stock muffler. The engine would run just great on the ground and you could shake it all over the place it would be fine. Then up in the air, every flight, dead stick out of no where! After spending $100 dollars on these various attempts to correct the (cheap?) engine, I bought a 4500mah C cell and a switch (total cost less than $10, weight a few ounces) and hooked it up as an on board glow. The engine has run like a champ ever since. Not one dead stick in 40 flights and I can idle to the point I can almost count the revs.

Even if this isnt a great solution for you, I would try on board glow first because it's gotta be the cheapest option and it will hide a lot of tuning issues from giving you dead sticks. A 4500mah cell gives you about 2 hours of flying. I wouldnt even mess with the fancier on board glow controllers. In my experience you just dont know what throttle setting the engine could die at!



Cheers for now!
