Everyone is an expert! RCU has taught me that! lol


You are right about the bigger engines and the time to react in the speed limit events. I have way more experience flying 80, than I do any other speed limit. 70 is too slow IMO as you almost need a specific design as you can start to have stall issues at high angles of attack.

The modern .25 engines weigh as much as a Fox combat .36, and are of higher quality really. They are easy to tune back to the 75 mph speed. In fact, I have 2 new .25 ASP's showing up tomorrow. I am getting a couple of custom venturis as well for this engine. They are tapped out on the bottom to accept a nylon bolt, which can be screwed in to choke off the air, and fine tune the speed. I am excited to build a new fleet of speed limit planes and get some new engines on them. I have a full slate of projects for this winter!
