This is not like the Hi Johnson stuka, only thing close is the wing. I have Hi Stuka and original plans, fuse is not same measurements nor stab, push rod is outside, fuse has different movement . I bought a BJRM kit and was disappointed for sure. The wing is a lot of work to build for a plane that doesn't turn good. Make me an offer and I may sell the kit to you, never been touched. There is a lot better planes to build for electric.
