I have a SPE 26cc gas engine and I was thinking of putting it in a profile. The only problem is I cannot seem to find a suitable profile kit or ARF for this size engine. I was thinking something along the lines of the golden eagle profile that is made for the DA50, but obviously in a smaller package. Since the gas engine I have does not mount on rails, that is the other issue I have to consider.

GREAT IDEA: Also I sure wish the ARF producers would get on the ball... and get a ARF profile for a 26cc gas engine on the market as soon as possible. Kits for builders also. This size of engine is great. It would be a great plane for RC fans just getting into gas power. Once they learn the do,s & don,ts its on to nicer planes. Capt,n

What weight would this have to be for decent 3D and unlimited vertical?

I would guess it should be in the 7-10 pound range. I have a 26cc gasser in my 10 pound extreme flight yak and it has pretty decent vertical. I would think a profile could easily come in at 7-8 pounds. Anyone know of any models that would work? I took a look at OMP's 120 size profiles, but I am not sure how you could mount the engine since it does not have rail mounts.

I designed and scratch built one a couple of years ago with a G26 on it. It was a box fuse not a profile, but it still worked great. 1130 squares and 9.5 lbs. REALLY stong hover pullout and great harriers. I contacted Mike M from Hanger 9 because they were handling Zenoah. I just wanted him to think about designing one because since mine worked so well I knew the size/enginge class could be valuable to modelers. i think he thought I wanted him to kit my design which was not at all what I wanted. Anyway, no response.

The point is, the numbers can work out for a 3D plane in this engine class. Its just nobody has done it yet. Cheap price of gass sure is nice, though.

So, has anyone modified an available arf or kit to accept a gasser yet? For example, the 110 sized profiles that OMP offers. I am just wondering if there was some was you could incorporate a piece of plywood into the profile frame that would allow you to bolt engine standoffs onto it.
I suppose the other option is the get a big ugly stick and use the gasser in that. Basically I was looking for something cheap to throw this 26cc engine in so that I would not be concerned about learning new maneuvers or crashing it. I think everyone needs a plane like this that they don't really care about. I have several other gassers, but they are all so nice and pretty that I don't seem to get as aggressive flying them as I would like. Case in point, I had a cheapo ebay katana profile that I picked up for $40 and slapped a saito 82 on. With that plane, I would fly so low inverted that the rudder would drag on the ground, or I would snap roll immediately after take-off only a few feet off the ground, etc, etc. You get the point. I would never try that with my $2000 wild hare extra.

Yea, I have a 26 spe on my omp yak 65 7lb 12oz. I cut the bottom motor mount off and bolted alm angle to mount the motor. It pulls out of huver ok but not a rocket. 17x8 menz prop.

I mentioned my scratch built just to throw out numbers that work. Something else I did that many others did as well was to use a G26 on an Ultrastick lite. Strong hover pullout, easy TRs but you really need to know how to control wing rock in harrier. I just doubled the firewall and put the servos in the tail. There are some great threads on this mod.

I was looking through the classifieds and saw this:

I thought that would make a nice airframe for a 25cc gasser. Anyone agree??

not enough wing 4 a heavy gasser in my opinion.

JIMnJILL

Is a gasser really that much heavier? I think a light 25cc gasser weighs about a pound more than a Saito 180, but you can effectively carry 10 oz less fuel easily.

How about the Morris BalsaNova? http://morrishobbies.com/product_inf...93a7793fece21e

It is kind of a hybrid between box construction and profile. May be better suited for a 35cc engine???

I'm not sure what the answer is, but I would LOVE to see a profile plane with plug-in wings and unlimited vertical performance on a small gas engine. Maybe I am asking too much.

Like I said i have a omp yak 65 profile with spe 26cc gas plug in wings unlimited vertical. 1200 sq.inch of wing.

asmund

The mvvs 26 and 35cc both have rail mounts and should be easy to fit to a big profile, the 26 is very light too as it is built like a glow engine(same for the 35 for that matter, but it is heavier)

AeroDave

I like the OMP Yak. Thinking about the Evo 26. What do you guys think?

I think its too heavyto get your cg. the spe 26 weighs 36oz with muffler& ing. Unless u want to use heavy servos in the tail and add some lead.
