I built two of the Rich Uravitch Fokker D-VIIs at the same time from his plans sold in Model Airplane News several years ago and they were very easy builds and great flying little planes. I have flown mine with an old OS 46 until it wore out then I changed over to the OS 46LA and it flies just as well with that. 49 inch wing span. Not as much work involved building your own kit as most people think and it's A great starter for bigger and better plans built planes. A 52 four stroke would be perfect for this plane too. If you want to try A plans built plane I can talk you through most any of the little problems you may run into.
