I recently emailed back and forth with Dave Lewis at BUSA and discussed engine selections for their SE-5A 1/4 scale kit. He told me that the kit was test flown with a Zenoah G38 and that flew just fine. I asked in particular about the internal dimensions of the cowl in relation to a couple of engines. After that, I decided to go with the new OS 33 gasser. The fit and finish should be fine with just a little bit more weight up front. For me it was a toss up of either a DLE 35 or the OS. I chose the OS and we'll see how it works out.

Cheers,
