Christmas came early My hawk arrived today. Pictures of basic package already posted so I'll just post a couple of special ones and make a few immediate observations.
This is one incredible ARF. One of the best I have seen, and I've seen some of the best. It is very light but built with a lot of interlacoking parts and reinforcement in the right places. Just look at that engine box. The covering is imaculate and my hinge slots are dead straight and centered.
It's a good thing I haven't bought an engine yet because this is a very unique plane that is going to take some thinking and research to come up with a gasoline engine that will fit right. The engine prop shaft is offset an inch below center just like the real Hawk. Also the engine box face is not that large: 4.5" wide and 4" high.
The cowl size in the engine location is 7" wide, 4.5" above the prop and 3.5" below the prop with about 6" of offset from engine box face to front of cowl. I researching hard because you can almost mount an engine upright in this bird. I'll let you all know what I find/decide. When I first saw the plane I was a little surprised. Iexpected it to be bigger visually. But this plane is not really a gasser; it is a true 1.20 glow size plane, as stated I might add. but I hate glow and will get a gasser in her somehow
There is quit a bit of space inside the fuselage for CG adjustments and placing a smoke tank; albeit some is hard to get to easily.
Added PS: Well after more research, it is going to be near impossible to get a gasoline engine in this plane without completely chopping up the cowl. Practically everything I see will stick out the bottom a couple of inches or more. The only gas engine that may be able to mount upright is the RCS 1.40, but the sparkplug will stick out the top and the engine is too light. So ifanyone has any gasoline engine ideas I haven't thought of, let me know.

Steve,
Got my Hawk today as well. This thing is huge!
Rethinking engine options. I've got a K&B 1.00 that I fit with out having to cut the cowling for. A 25cc or so gasser would definitely fit with engine box mods and you probably wouldn't need the nose weight box.

Mike, you haven't even flown the Ultimate yet, why on earth get this thing.
I'm not moding anything. that's why I buy ARF's But it's not just the engine box. the plane was designed to have that "low" crankshaft and that is scale. I have determined that the G-26 may fit in the cowl mounted upright. I'm also think, if I win the lottery, that a Laser 200v would fit nice, albeit costing twice as much as the plane.

With careful measuring and a "short" plug it should fit. but the exhaust and throttle linkage is what I'm trying to get figured out.
Rowdy1, you may want to take a close look at things. I had looked at the MVVS/Evolution engines and decided that front mounted carb didn't give enough clearance. Course if it's mounted inverted the whole thing will stick out anyway.

Yes, I have talked to Mark at RCS and I'm leaning toward the Roto35, inverted. The Roto because it is a very clean lined engine that will not look as bad as some. There are a couple of engines that will fit upright, but there is no resolution to the cooling issue without hacking a big hole in the front of the cowl. I really do not want a glow powered plane. It's gas or sell it.
Dick, did you find the G-26 unacceptable even inverted? thanks and why? Clearances?
