If you get the CUB just remember 2 things. On takeoff keep the tail planted on the ground until you have good flying speed (especially if you are flying from grass) then let it come up slowly and always coordinate your turns with both rudder and aileron. On some Cubs the ground handling is sometimes poor and on takeoff it can nose over pretty quickly if you are not careful. I usually find that the H9 80" Cub has the main gear directly under the leading edge of the main wing. It makes it diffcult to taxi and takeoff, but allot of people move the main gear so the center of the axles are about an inch in front of the leading edge and it helped a lot.

If you have never flown coordinating rudder/aileron. I suggest you practice it on the trainer first. Even the trainer will turn better but with the Cub it's a must. If the new radio you are getting with the Cub has mixing capabilities may I suggest that you do not use them with the Cub until you get coordinated turns down pretty good, then setup the mix but remember to turn it off coming in for a landing.

In my opinion the Cub it a great plane and once in the air will do most areobatics but it does them at a very leisurely pace, so do not be in a hurry,

I learned to fly full scale in one, but you need to be mindful of it's quirks. This also applies to most of the R/C models I have seen
