If you haven't read this thread already, I've posted pics and info on my Kadet Sr ARF taildragger conversion here:

I just maidened it this morning and it flew beautifully. Unless you're a rank beginner, I'd say the taildragger conversion is a must. I especially like the wheel pants I added. Mine came out right at 8 lbs and balances perfectly with an ASP .75 2stroke. The darn wing is so big, a couple of lbs is nothing for it. The Magnum .80 4stroke will be perfect for it. I doubt you'll have balance problem with that engine. Go for it!.
