RE: Rollin' my own 50CC Yak 54
Ok, made some progress albeit somewhat limited. I've cleaned up the cad file so that everything is in perfect alignment. I want to jig build this so it is crucial that everything is as close to centered as possible right from the get go. I lengthened the fuse somewhat from the previous pictures. I wanted to get close to a 1:1 geometery between the wings and fuse and it was something like 1.3 to 1 based on the scale version. It's now down to about 1.1 to 1.
As it is now, the wingspan will be 86 inches and have a total wing area of around 1550 Sq In (including belly of fuse). The fuselage will be 78 inches. I may need to lengthen it a bit further though to prevent a nose heavy situation. To compare, the EF yak has an 87" wing and 85" fuse with wing area at 1450 Sq In.
This picture shows that I will have round and elliptical formers that wrap around a "box" structure which serves as the main support structure for the engine box and landing gear. This is pretty much what the EF yak does too.
Cheers,
John
