Peter first let me address the takeoff problem that Mike has brought up. Most Cubs as Mike mentioned do require vigilance on take off during the throttle up due to the dynamics of a taildragger, among them: 'P' factor, gyroscopic reaction at rotation and spiral propellor wash plus some more subtle ones. Now factor in the vary narrow track main gear with a high deck angle in the three point attitude and you have the makings of a tricky take off and this does apply to most Cubs that are somewhat close to scale even some of the little electrics.

Now does this prevent the average sport pilot from enjoying the airplane? Certainly not. First if you have a lazy left thumb you will need to become more proactive with that thumb and you can do this even with your tri gear trainer, just practice runing the trainer up and down the length of the runway just below liftoff speed and steer with that thumb (by the way if you fly mode 1 down under that would be your right thumb). Lets dig a little deeper Most folks first flying a cub use far to much rudder throw and really compound everything. Just use half the throw as you would a wide track taildragger. Some would say what about aerobatics, snap rolls, knife edge etc. well outside of the fact that all of that is very, very unprototypical for a long wing full scale J3 cub its simple just use dual rates on the rudder. I know your next thought your Flash five X does not have dual rate rudder and you would be right but it does have another bit of magic called expo and its avaliable on the rudder with that radio. Just crank up 40% minus expo on just the rudder and you will be tracking straight as an arrow in no time but can still do all those silly unprototypical things in the air.

I have flown all three sizes of the GP glow cubs but not the arf version which is somewhere between the forty and sixty size kits Most likely the design is very similar. The two bigger kits fly very similar to the hanger nine. Here are the diff's I can recall: the GP has slightly less adverse yaw, the GP is a little more difficult to do a wheel landing (three point is easy), the Hanger 9 is a little less stable in takeoff and the GP will stall just a tad slower.
The GP Peter would also be a fine choice. By the way the three sizes of GP float kits are great floats (pun intended) and I use them for that cub and some other types.
