Its one of the easiest builds Ive ever did. The servo extentions are a pain to run down through the fuse but other then that its pretty straight forward. You may want to scrap the instructions as the suck pretty badly....good news is you dont need them. Oh an for your throttle servo wire....you ll have to cut a hole in your wing sheeting to run it back as they dont have a precut one in place. The suggested CG is very conservative, you ll want to end up about an inch behind the spar. It took me longer to mount my radio eqp then it did to put it together I think. Run into any problems just hollar.
