I have had 3 engines go bad on me in the last 3 months, first an enya 25 on a canard, dead sticks , then an os 46 on a super sport gp, after 20 seconds of full throttle on bench flam out right there and low compression. and last a 61 os at idle shts off high end OK. Im useing a good morgan fuel, I dont have problems with 4 other glo planes of same size and smaller even a 15 runs good. Can an engine just wear out that starts ok, runs ok for a while 1/3rd tankfull gets to hot maybe or looses compression,then dead sticks , and then eventually dont run after 20 seconds on the bench? my prpblem now is with a supposingly good os 61 in good condition with lots of compresssion new plug f8 and all new fuel lines, it just dies at idle but runs better a high end. its on a new twister hang 9 arf and I dont want any dead sticks. whats the voo doo. Thanks any one ][/img][img][/img]
