Hi

I have a JP SWift which is a sports/glider, after building the plane I set up the COG to the manufacturers spec's, on test flights it was way nose heavy and I started removing weight I had added, after a while the plane was flying nicely and glided well but somethig changed when coming into landing it would start porposing and the only way to stop it was either up the air speed which you cannot do if coming in dead stick or a bit of down elevator which made the landing hot and heavy.

So after 3 flights with this happening the last landing was to much and torn my landing gear out and split the fuse.

What has caused this? Is it the COG or just landing speed?

Many Thanks Lawrence
