I could be wrong on my estimates, but a friend has a reaction and has flown both a 30 pounder and a 37 pounder on it, plane did never get near 180-190 mph, I would say no more than 160 mph at best, I have a Flash and I'm biased towards it, I personally do not like the Reaction. A few of my friends have PST Reactions, if you want something relaxing, get the Reaction, you already know the Flash. My friend says the 30 pound turbine is a better match for the Reaction than the 37 pounder, I have seen it fly and I would agree, so you should be OK, yes unlimited verticals at 37 pounds of thrust but nothing more for the extra power...
I have flown seflyer's Reaction ARF and it does scoot.
Fastest one I've seen.
