I guess I'll have to measure them and let you know.. try to do that asap when the rain stops (again..$%^%&^). So far it has been running and tuning by sound smell and touch. But the Rpm is respectable on the 8-4 and the vertcial lines on the 2lb aircraft (dry) are very tall, and it will hover with someone adept at the sticks.
Even if just for bling, I intend to snag a Macs header and pipe it on the Contender.
