I don't have the box or the instruction manual so I am going from memory only. I believe the wingspan was 59"-61", not sure of the fuse length. The egine required was a 90 four stroke and I mounted an older OS 120 fs which was mounted via vibration dampners to the firewall. The servos were Hitec 605's, except throttle and rudder. The Rudder I think had a Hitec metal Gear. The wing loading as I recall was not excessive as it was an extremely gentle lander, in fact the larger engine I believe was used to compensate for the lead that would have been needed.
