The SR was a major part of my learning curve.
Truthfully, though I'm a fan of E-Flite and their products I rthink that overall the SR is a ...turkey.
The tail rotor motor sucks for lack of a more eloquent way to put it. It's heavy for it's s ize. The tail rotor motor , even when a new one, is mediocre at best.
Since you can fly the SR around if you flew a Blade 400 you'd LOVE it. MORE stable, way less suseptible to wind, just flat more fun. Horizon has a video on their web site that shows precisely how to cinfigure the radio for a first 450 collective pitch heli.
Align makes great products. However, there is a reason web sites are drowning in used 250 T-Rex's for sale. It's very 'busy' to fly, not at all relaxing. By the time its ready to go that attractive price is more than the Blade 400 even when the 400 comes with a 6 channel computer radio with a 10 model memory.
Think hard about that 250 and ask yourself what it is you want out of your next heli. Doug
