Mores law applies if some is good more is better! Like it was said willl the airframe take it! I have a LT-40 Sig! I'm running a magnum 91 fs in it! I sheeted the top and bottom of the lead edge of the wing! I aslo fiberglassed the wing saddle! I do banner tows with it and other fun stuff like parachute drops!
Peel some coveriing off the center of the wing and glass the wing saddle. If you ambitious strip the whole wing and beef up the spars add some shear webs! Make sure you tail feathers are good and tight. Also seal your control surfaces to eliminate chance of flutter! And most of all have Fun
