This is probably as close as you will get to 50cc in a 4c glow engine http://www.horizonhobby.com/Products...dID=SAIE325R5D note the prop range is about the same as a 50cc gas i dont know the exact fuel consuption but i can tell you its goign to be VERY high and also look out for the cost [:@] (we can count that those numbers were probably taken using 30%nitro fuel and thats gonna get real costly real fast.
