Chopper man
I'm still pretty new at this myself (just soloed in December) so maybe info from another newbie might help.

My trainer is a Goldberg Eagle 2. It has a 63 inch span, weighs about 5 1/2 pounds, and I fly it with an OS 46AX. You didn't mention specs on your Tower, but if it is the 40 size it is a bit smaller and lighter, and if you fly with something like the OS LA40 has significantly less power. These might be factors in how much wind the plane (and your skills) can handle.

With mine I found that I can do fairly well in winds up to about 15mph with gusts a bit higher. The plane has the weight and power to fly well into the wind, but managing the speed it picks up downwind made learning landing approaches difficult. Crosswinds are definitely an issue as others have mentioned. Trying to keep field alignment (our paved runway is only 20 feet wide) and still keep the wings level is a major challenge for me in that situation. However, I am learning to use the rudder and if I keep rudder input small I find I can get the plane to crab over moderately and yet still keep the wings level as they need to be to land.

One issue with more power, though...I do not have a computer transmitter and, therefore, with the AX fly at less than half throttle. This means that throttle inputs for landing have to be very minute (a click at a time) as I only have about 1/3 of the total throw to work with. I don't mind this as I think it helps develop control sensititivty, but with the adjustments of a computer transmitter that would not be as much of a fussy issue.
