Hi All,
I have just purchased one of these and am having difficulty deciding on a proper engine. This is by far the largest plane in my small but ever growing hanger. I'm also on sort of on a budget with regard to my hobby purchases, so I need to keep that in mind when aquiring all the other components I will need to make this thing airworthy. So far it looks like the kit itself will be the cheapest item, since the engine, retracts, and radio gear each seem to be well over the $220 I paid for the plane. 
So, back to my engine decision. My first thought was to go with the 120 size 4-stroke as recommended by the manufacturer, but I am concerned that it might not be quite enough power for my lumpy grass field. The next size up would be nice, like SJN, a 150 Saito perhaps? Couple of concerns with this idea. 1). Pricey at $370 or so. 2). I hear that they can really suck down the glow fuel...at a rate of maybe 1oz/min? This could be costly to run, when my glow fuel cost $16/gallon. So considering these items I began thinking of a small gas engine. I do not have any gas planes, and so do not know much about them. Would it be feasible to try and fit something like a Zenoah G26 on this plane? I understand this engine weighs about 3.5lbs so that may be of concern. However I understand the Zero has a short nose and generally requires significant weight on the firewall to properly balance. Therefore a small gas engine might be just the ticket? A few benefits I see with a gas engine would be: 1). Cheaper to purchase, the G26 goes for $299. 2). Fuel cost is much cheaper, $2/gallon. 3). No messy oil cleanup on the plane. I think the G26 would still fit the 8" cowl quite nicely too, with just some of the bottom cut away for cooling and the spark plug.
Any advice/opinions/pros/cons of either going the large 4-stroke route, or trying my first small gasoline engine would be greatly appreciated.
By the way, I just had to take all the different parts out of the box when it arrived and check them out. I am amazed at the workmanship and quality of the construction. It seems very well built and the finish is first rate. It is very much worth the price IMO.
Thanks,
