I had a Tower Hobbies Extra Special, which is basically the same airplane. I flew it 400 times before it just started falling apart on me. Since then I've built a Fun 51 and just recently sold it...

I can honestly say the most fun I have ever had flying was with that Extra Special. It's would spin so dang quick it wasn't even funny. It would do incredibly fast inverted flat spins, without losing altitude on a good day. Upright were great too, but it would lose more altitude. This is the easiest plane to flat spin you will find...Basically all you do is kick in full rudder. You can enter from any attitude from any manuever...

With spoilerons it will harrier great...Takes practice though, not as easy as it is with other airplanes. Harriers are definitely not it's strong point. There is a lot of wing rock. I don't think a proper elevator is possible...

I learned how to hover with my Somethin' Extra's and then used the Extra Special to go the next step. I was doing tail touches everytime out. It's lighter than most of these other profiles so with the same engine will pull out much quicker. All that builds your confidence. It's very easy to hover and torque roll. All control surfaces, especially the rudder are very effective.

Knife Edge on the Extra Special was great, will be almost as good with the Fun 51. Knife Edge loops were also easy...Falling KE was fun... I used to point the nose down at full throttle and roll to the side and kick in full rudder and watch is completely slip around on it's side and pull up.

Mine would also do a positive conic lomcevak...Never found another airplane that would do that.

As far as building goes, reinforce the landing gear area. Double it up with plywood and then cover it with fiberglass cloth and CA before covering it. Buy some of the Dubro profile landing gear, that is a must. Enlarge the rudder and elevator on the Fun 51 by 1/2 an inch in length. That will bring it up to the size of the Extra Special. You can add 1/2 inch to the ailerons if you want too, depends on how much you like rolls!

Besides the landing gear and landing gear mount, it is a great airplane. It's a better kit than those $110 Morris Hobbies airplanes! You're going to love it.
