RE: Engine selection for Nexstar ArF help
its best to stick within the suggested engine sizes with this aircraft, it is just a trainer afterall, i bolted an OS 46LA to my Yamamoto, maxed the throws and what a blast! breathed a whole new lease of life into the old bird...
LA's are fairly basic as engines go, but they have a good amount of punch for their size and aslong as you look after it, in return it will give you many happy flights
