RE: 50cc Sukhette Build Thread, now in progress!!
If you keep everything else in balance it will do just fine. If you go redundant everything, no, it won't be enough except for "normal" aerobatics. If you keep things light and use good products that are reliable enough to permit singular use, then yes, the engine will do the job and even permit 3D.
Hint; toss any manufacturers H.P. numbers out the window. They were probably developed by using a small prop at very high rpm. A much higher rpm count than our usual propeller sizes will ever permit.
