I fully expected to work on the fit/finish of parts, but everything went together accurately and solidly. This design is both lightweight and well though out. With the great parts fit, the assembly was much faster than I am used to and all of the bolts/screws lined right up (I normally have to spend a few hours getting a good fit on wing/stab tubes and other parts). I used an older 3W-60 with a J-Tec large volume Pitts muffler which is a bit heavier than the newer design 50 class engines so I moved the battery packs behind the wing tube to balance. There is plenty of well thought out room in the interior for mounting battery packs and the smoke system which I have not yet installed (there's still plenty of room for the smoke tank on the CG). Even the wheel pants mounted right up with the included bolts without any fuss!
I will add to this review after flight balancing and report the handling as well. I have no doubt the SBach will fly great, especially for as light it turned out. I will be purchasing more of these kits in the near future and would love to see some models in the 100cc class.
