.46AX is cheaper at the moment, yet powerful and good overall. ENYA CX is similar current price as O.S. 50SX, but better and stronger than either in practice.

I'd say you're right. [8D] I'd also say that whilst a great looking and fine flying model doing what it was designed to do, that CAP is not a 3D design, and you could have chosen better if that's what you predominently want to do with your flying?

A stronger motor will unquestionably help outright vertical performance, but a .61FX won't make it hover any better than a properly propped .46AX. In fact probably worse with all that extra weight up the front and a more forward CG. ENYA's CX50 is a decent alternative choice to engine this plane if you wanted a little more vertical punch, but I suspect you'd still be unsatisfied as it's not going to give you the power to weight ratio you really want. A bull of a motor with a more user friendly torque curve than the AX, a bit more grunt, and with a great carb offering superb throttling. However your AX fitted with an APC 12¼ x 3¾ hover prop would probably hover as well as either alternative.

Here's the real fix and obvious best solution.

If 3D is what you want to do, don't buy another motor for the CAP which is a good plane but was designed to fly conventional aerobatics. Spend the money you were going to spend on the motor on a dedicated 3D plane instead, put the AX into it and fit a hover prop. Voila! There are a plethora of 3D offerings in the market which wouold be suitable, but as a well tried and true recommendaton, [link=http://www.rcuniverse.com/magazine/article_display.cfm?article_id=240]Model Tech's Magic Extra 300L[/link] which you can pick up for around $150 or less these days will harrier and hover like crazy plus have that unlimited vertical you're looking for - on a 46AX! Looks great in the air to boot and isa mucho funo...bringa bigga smila to yor faso! [sm=sunsmiley.gif] Wouldn't be without one in my hanger!
