Brendan,
I have one that Bob Branch assembled a number of years ago but not sure if he ever flew it. It made its way to me through Frank Carlisle. Power is a Turnigy G15, 950kV motor, APC 11x4.5 electric pusher prop, 50A generic ESC, FM-9 timer and 4 cell 2200mAh battery. I normally run for about 2 minutes with this set up but end up pulling a little out of the batteries to bring them back to storage. Probably could go 2:20-2:30 and be just about right for storage. I believe I have the timer set up to run around 50% throttle. Needed to adjust to get the level of climb/hover that I wanted. Unlike the slimer version which will change from beginning to end of flight, this one stays pretty consistent. If it has not been done already, I would replace the wire gear with aluminum dural to keep from busting the spar in the wing with hard landings. I think that either the Smoothie ARF or Vector gears work pretty well.
Had this one out just yesterday as it was fairly decent out, there was still snow on the ground and it was fitted with some DuBro skis. Another good feature of the Slob is that the more it blows, the more fun and the easier it is to fly. My go to airplane for bad weather. Good luck and have fun.
