I was told the Zenoah was sufficiant for field flight and it would only fly scale like. However, after discussing this with some friends at the field I was advised that changing it over to floats would require more power. I believe this to be true since the floats are massive, 47in and getting it off water, not to mention the additional drag involved would require an engine of at least 3hp or better. I have decided on the NGH 38cc four stroke gasser which has 4.6 hp. This should be more than enough power for my needs. I currantly fly a Piper Cub with a OS 70 four stroke and I love the sound of it. My question is, is this a good choice or is there an alternative engine size that I should consider? Hobby King has relativley cheap engines and I have researched the 38 and found nothing but good reviews. The 38 weighs about 1lb more and is 1in longer than the Z26. Also the 38 runs on gas which is much cheaper than a glow engine of comparable size. Any advice on this choice of engine, or suggestions to alternative engines would be greatly appreciated.
