I heard its either the f4u or p47 thats next in line for the ARFing. My biggest question here,people doing this and that to make a stand off sport scale plane more scale while doing the single biggest no no for achieving that look in flight. All these huge engines that require butchering the cowls and such,wondering whats enough power,lets get back to reality here. If your 1/5 scale p51 is doing around or over 120mph in level flight,what will that scale up to in full size(I dont know the formula but I'm guessing here),over 500 mph.I know the reno racer 51's are around there but NO WW2 P51 was ever close to that, only in a substained dive. The real P51 wouldnt even break 400 mph untill near 16k where the supercharger starts to show its effects. Do any of you people go to full size airshows? A 1'=1' 51 rolls a good long distance before getting light on the wheels,and climb outs are shallow,and these are modern day lightened 51's carrying less fuel and no armament like the real ones back in the days. I go to alot of both full size and rc shows,and I can tell you that a fairly close to scale looking model flying at a realistic speed looks more scale in the air than that shinning beauty thats zipping around at 130 miles an hour. All this talk of" is 50 ccs enough",is crazy an os 1.6 will fly it ,closer to scale speeds, save you money and weight.Look at the planes winning scale contests 25- 50 pound models flying with moki 1.8 and 2.1s, and g62's-these are 92-106" hellcats, tempests and such. I know its not my business but that person who want to go with 80cc's in this airframe leaves me to wonder what he is thinking?Why go with this mass produced airframe to totally strip it down, reinforce it(I definetly would reinforce any airframe built for a us engines 41 cc engine to convert to a 80 cc monster) and redo it when you can get a better flying, more scale larger model. By the way I know that us engines 41 cc is an anchore, but those speeds someone quotes of 80-90 mph are about spot on for a 51 of this size. I had a pica 1/5 scale 51 with a moki 1.8, that plane was slightly larger,and heavier at 26 pounds, and that 1.8 still hauled it around too fast,it just didnt look right unless flying at 3/4s throttle, but there it looked great.I know excess power is nice for getting off the ground,or out of trouble, but its the wing a plane is supposed to fly on,not just the pure thrust(the ole anything will fly with enough thrust theory). Well good luck with all of those stangs guys.
