Cost is not the big issue when it comes to the RIGHT kit and the engine. The problem with cost is a set of retracts that cost as much as the rest of the project and then they are a constant problem. fixed gear would aleavelate the worry all together. is this oleo strut the for lack of better discription like a shock? I'll look at the barton retracts. For the stuka, what is the wire frame you speak of??
