I have a Venus with an OS .70. It has *plenty* of power. If you have that engine and want to put it on a plane for sportsman, I'd suggest either a World Models Tai Ji .60 (had one and it was awesome), or for less $$, a World Models Intruder or a Swallow. Seen all of these fly, and they are very stable. Last weekend I watched a couple of Swallows and an intuder battle all weekend for first place. Any of these combos will fly sportsman better than a Venus.

The Venus is the best I've seen for a .40 size plane, but with that engine, you can go to a larger design and do much better. The Swallow and Intruder should both be close to your price range, Tai Ji a little more.

In Pattern, you want a lightweight, straight airplane. All that excess power will do is help you to scream through the box. As long as you have enough power to do the verticals, you're fine, and a .91 is just plain overkill on the Venus. My 70 will hover the Venus and easily exit vertically. No more is needed. Hope this helps, Chuck
