Pretty freaking good seeing how I got my L3 with a M1297. About as easy to assemble as most any other reloads. The only thing I had an issue once with was the grains were too tight to get into the liner. Not a big deal just peel off a little bit of the outer layer of paper on the grain and was good to go. Then again, I've had very similar experiences with smaller reloads as well.
I looked at that one, will do a rrrock sim when I get home. She is aall built but without paint yet. can guess the weights of chute, cord and stuff. What have you flowwn with the 2050? I fly my 1/52 Saturn V on the K2050ST, and that is great.
I got one with my COVID stimulus last year for my eventual Level 3 flight, since it's an expensive piece with a long lead time to get one. I'm hoping to get the documentation together and submit to TAPs this year.
