Mobyal, I see that you've ordered a Sparrowhawk. I've been seriously thinking of get one too. I went on-line to Atlanta Hobby and downloaded the pdf manual. The manual is very typical of the China/ Vietnam model companies. Mostly pictures and little good info. On the first page of the manual it says for engine size...1.60 2-stroke and 1.80 to 2.00 4 stroke???? Yikes, that even bigger than whats been advertised. Seems WAY too much power for that size airplane? Plus in the advertisements it mentions a 20-26 cc gasser but not in the manual. Looking at the manual it shows an O.S. 4 stroke inverted, using a strange looking muffler, and really carving up the cowl. I'm not to thrilled about doing that. I'm also wondering if a small gasser would even fit inside the cowling? The rest of the plane looks good. The model uses a pull-pull cable system for the rudder and dual elevator servo's which is good. The landing gear looks interesting also. Looks like a bit of a shock absorbing bend in the trailing link gear wire. All-in-all, it still looks pretty good. I'll be watching for your posts as you start to build. Mike (ACF)
