RE: new demon to fly soon!!!
FINALLY!!!!! the deman flew today! the YS 45 ran good on the mac's header and pipe (not great yet) still needs to be tuned. i don't know what speed i got but i left a bunch on the table still. running 30% nitro and a 9-9 APC prop i only turned 14700 rpm on the ground. the engine has only had two tanks ran through her on the ground and three in the air so it will get better i hope.
does anyone know what this engine will like aqs far as props, fuel, and header length?
