when I had the 160 in it, we kept dialing it back...ended up around 24-26 lb thrust.. plenty to go vertical (midwest).. If you have all the speed out of your system, then build it light weight and use one of the smaller lighter engines.. thats what Im doing this winter.. I saw one fly recently with a Tam pipe, lighter servos, and less than 20lb overall weight..yes, less than 20lb.. with a P100.. it flew absolutely beautifully.. would slow to a crawl.. plenty of smash.. Im going to put a wren 100 in mine with the stock pipe, and toss the pilot/cockpit, and take out the smoke.. that should bring me in around 22lb.. FWIW
Yea, I have to agree with you. I prefer the lighter wing loading, less residual thrust and being able to slow it down, though a lot of flap can assist there. I was planning on the Rabbit, but I like to see what others have done and the results they get. Like I said before, I don't need to go ballastic, spent 10 years flying bandits doing that, getting older, like to relax a little more.
Totally agree, have flown flash with Rabbit 100 at 21lbs, and Cheetah at 22lbs aircraft weight. With the lighter engine, the plane handles SO nice, still does 180mph, take off and landings in 150ft. It is faster with the Cheetah, about 225mph but, doesn't ''feel'' as light and becomes more of a straightline speed plane.Also, higher residual thrust and more time to spool down with a bigger engine.Â* I like the way it will slow to a crawl with the smaller engines.
I fail to see why people continue to hang bigger and bigger engines in them? You get marginal speed gains and lose handling. The Flash was designed as an aerobatic sport jet, not a speed plane.
