i just got an accell hobbies katana gs 40. i put an o.s. .61 sf on it. i need to know if any one has this plane and where they put the cg

or how far back can i go without causeing problems... i have it about right on the spec and it seems to be alittle nose heavy

also is there such a thing as to much aleron control on one of these?? i am having trouble finding the sweet spot for a flat spin and when you roll it from a positive AOA it will roll a few times good then start to fall on its nose


if any one can help let me know.........................................thank s cantw8tofly
