I have read all of this thread and the RCGF and DLE30cc thread. The big question everyone asks is, “will it fit?”. Of course it will fit if you get a big enough hammer! I have two of the 15cc engines and love them. They start easy and run great. I have one that I am trying to break in but it takes Forever to run a gallon of gas through that engine. It sips fuel!

Back to the “will it fit” question. There are planes out there that this engine will fit. But very few because of cowl, firewall position etc. The problem is not the engine but the planes. The guys that fly the big 3D planes have no problem because the planes are designed for the big gas engines. The smaller planes are designed for the nitro engines, period.
<o></o>
This is really a shame because the engine manufactures see the demand for gas engines. You can get just about any engine you want for just about any price. If you need an engine that is the same size as a nitro and just won the Lottery you can purchase a Saito 14cc four stroke gas and it will fit your place perfectly. But again, there are few planes that fit the bill for size weight ratios. I have installed an Evolution 26cc in a friend’s KMP Stuca and it is a beautiful engine. But again, it costs 450 dollars and again, what is the deal with the silly price of the replacement ignition module.

It is time for the plane manufactures to wake up and smell the roses. Gas engines are here to stay and they need to design planes for them. The 15cc will work fine in a plane designed specifically for it. A few more inches in the wing span or chord. A little longer fuselage to offset the weight up front and you’ve got it.

Examples of what we have now:
Hanger 9 ¼ scale Cub or Taylorcraft. Designed specifically for the Zenoah 20cc. Would obviously work great with RCGF 20cc.

AMR (Aircraft Modelers Research) makes a 26cc trainer that would work great with a CRRC or RCGF 26cc. But in my opinion it is pricy at 249 for a kit that I still have to put together. At lease they are trying.

One sweet plane that I found is from a company called Abell Hobby. It is a designed with all sorts of hatches and doors for adding drop boxes and cameras. Again, still a trainer but looks fun for a Sunday flyer, which is a great start. The best part is, it is a ARF, and sells for under 200 dollars! This plane is similar to a Telemaster but less expensive. AND, the wings AND fuselage comes apart for easy transport.

I am not trying to promote any of these planes. What I am trying to say is that it is time for a new plane (ARF) designed for the 15cc engines. It can be done and it does not have to be a trainer or 3D plane. A 60 size Cub or P40 would work but they would need to recess the firewall more and build the front of the fuselage a little wider maybe. And then again maybe adjust the wing loading a little.
<o></o>
We will hopefully get back to the point of needing to find the engine for our new plane and not the other way around.
<o></o>
I any of you see any other smaller (under 26cc) planes that are perfect for our new gas engines let us all know.

Happy Flying!
