RE: Everything Radial Engines
HI guys, I have this question around but still have not a answer that is going to be a yes or a no.
I am building a KMP AT-6 88 inch wing span, the new that just come out form KMP, I want to put a 7 cylinder radial in her, I like the Seidel ST7-35 it will spin a 18X8 at 5200 rpm, little over 2 hp.
the cowl (230mm width and 245 length- oval of course) is just perfect for this engine( engine is 187 mm), if it was alittle bigger like 1/2 an inch it would fit the ST7-70(engine is 235mm)
the 35 cc wieghts about 2.6 lbs and the 70 weights 5.9 lbs.
But am I going to have enough power with the ST7-35 to fly the AT-6 or will it just be alittle under power or ??
I could make a new cowl to fit the ST7-70 but it be will much heavier to setup and with 4 hp maybe too much power as it uses a 22X10 prop
thanks for you info
Paul
