| Irvine 39 abc setup help
Hi , I have recently installed an irvine 39 abc in my heli , fingers crossed I have completed the running in correcly(1.5 lts of fuel(15%nitro 18%synth oil))I followed the manual for throtle and times. My problem now is the fine tuning, at the moment I have the main 2 turns from closed, when I start to lean in alittle more I can notice the change in sound at high throtle but when I drop the gas nothing happens for half a second and the revs increase with a distinct lack of smoke(up until this point there is plenty of smoke) and after a second or 2 the revs begin to come down, would I be correct in thinking that this is a sign of too lean? forgot to say that the engine is in the heli strapped to a bench with no rotor head or tail rotor assembly; if anybody could pass me any tips or infomation they would be much appreciated!!!
many thanks Snukiedog |
