If and when a race organization incorporates this model as a specific class, expect it to be in stock form and modification of airframe and engine would be extremely limited if allowed at all. Most likely they would specify and provide prop and fuel also, similar to the USRA F1GT class. Though I imagine altering the color scheme would be highly encouraged..... Looks like a nice model all around, I'll be getting one for sport flying and will race it if the opportunity arises. Would be nice if it works out that local clubs put on races also, rather than just the USRA. CG. quote:
ORIGINAL: kochj I have had experience with the evolution 26gt gasser. I actually tried it on a Funtana 100X w/ the tuned pipe. Well it turned out to be too heavy for my flying style so I yanked it and put in an OS 120 AX nitro. The 26cc GT had plenty of power for the 11lb plane, (more than the 120 AX) but that was with a Tuned pipe. I wasn’t able to compare the pipe vs./ UN piped but pier has got a web page with huge data on these engines. He is in the Netherlands and His Evolution engines are under the name of MVVS and have a red head on the 25, 36 gut’s. One heck of a good guy! http://www.mvvs.nl/ 1451 g for the 35 roto, and 1493 w/ the evolution 35. Close in weight, not sure about the performance comparison. I don't think that the evo 35gt is a big seller (because it is a odd engine size and it is in the heavy side) so I am not sure what kind of rpm's one is getting out of them? I don't have a whole lot of experience with gas engines (although I am assembling a 1oo DA in a cap 580, 40zdz in a GP Hawk bi-plane, and a DA 50 in a TF giant p-51 mustang. All of which are going to be completed in the next month or so. ) Will the cowling example be enough air for continuous sport flying, w/o overheating? Looks Quit tight in there and not that big of an air exit, for the picts anyway. Perhaps the cowl is really larger in real life an than exit hole is larger than I think (just like the pig spotters say on them) With so many airplanes to out together and little time, if the 35gt fits great w/o modification to the cowl (keep plane nice and smooth, to minimize drag. Rather than an oversized 50 hanging out the cowl I will go with the 35gt. There is nothing like taking a plane and putting everything together w/o any frustrating moments and countless hours of wasting by molding the engine bay in a plane. I am not sure what other formula planes cost in this engine size. I don't think there is even an ARF out there available to the masses that I am aware. If this plane catches on, there will be lots of folks modifying the evo 35gt engines to make them go faster and less weight. It should be very interesting. Cheers Kochj
