i finally got my .52 started tonight but i have a few problems it seems !! atleast every third time i start it it ran backwards the plane would go backwards instead of forwards i read on a post here that i should spin the prop backwards one time when it did this and it would correct itself, sometimes it would and sometimes it would still be in reverse! what causes this and what can i do to prevent it? i did the pinch test and it revved up pretty high before it died so i turned it a little richer and it sounded and ran great so i just ran it at about half speed for a while and it sounded pretty good so then i revved it on up slowly it would just die it would start right back (although backwards half the time) and run just fine and rev up higher but then the next time it might die again theres no way i could get it up and feel safe flying like this...... any suggestions ? also it seems to hydro lock quiet often............but it sure sounds mean when it is running like its supposed to!
