Dave, you did just fine in your first "B" team race at last years Regionals. If I remember correctly, you had a bit of carnage, but hey, that's racing. It would have been nice to have all the airplanes around the same speed, but truthfully, I considered us lucky to actually have 3 entries get into the air.
"B" tr seems to be an all out affair right now, but there's no reason we couldn't knock the speed down to something more reasonable, so that it may attract more Regionals competitors in this event. Sort of a NWBTR event.
One thing I wouldn't do is advocate the use of only using engines from the past. While many were/are fine, they are just too difficult to get in many cases, and truthfully, todays CNC manufatured marvels are much better, and last longer. Probably cheaper too.
Having raced O.S. LA 25's in the SSR event, I know that with a stock venturi and front mounted needle valve that this engine would be a very good match for a slower B tr model. Airspeed would be right around 85mph, and they get good range.
If I don't have time to build a new model for the Regionals, then at least I'll drop in a motor more suitable to a freindlier pace.
