Yeah I thought it was pretty cool.. I bet with a 40 you could really slow it down with all the extra lift you will get from the wide fuse and a 69" ws to boot.. Think it would be a hard plane to beat in a limbo contest at a fun fly.... I think i will skip using the OS 60, no need to make my sons first plane a fast one.. Looks like maybe a ST 45 will do the trick, last one i had was a great motor..........
