15cc Gas RCGF engine information thread
hello guys does anybodey think the 15 cc will power my hanger 9 thunderbolt 60 size or do i need the 20cc,help please its doin my head in, witch one do i buy?
The 20cc is my favorite so far for the 60 size warbirds. You have more power to play with.
I bought 2 of these little engines from David at Gas RC Hobby Engines to put on my new Uravitch 81'' Bronco. His support and service is great. I had custom mufflers built by Bisson and rotated one of the cylinders/pistons to allow both engines to face in board. I have run the engines on the bench and love the ease of starting and reliability. The airplane is finished and just waiting on better weather to test run and fly.
Go with the RCFG 20cc. I have two. One in a Hanger 9 Hellcat and another in a BH P-36. They both work great. Plenty of power but not "over powered". I think that the 15cc would be a little underpowered and not much difference in weight or deminsions between the 15 and 20.
It weighs in at 6.14 ounces. with no fuel.
If anyone has any questions, ask away.
Let me know what you think. I wsih everyone good weather and Happy flying!!!
I know it looks cheesy, but it works GREAT!!
So until the newly designed one is finished this one will do. THANKS AND HAPPY FLYING!!!!
Hi RCplanman, here is a picture of my Katana .46 profile I built up for the 15cc gas engine. It shows the way I set up the choke linkage.
I know it looks cheesy, but it works GREAT!!
So until the newly designed one is finished this one will do. THANKS AND HAPPY FLYING!!!!
I set up pretty much all of my planes from the 15's to the 400's with a very similar choke setup. Simple, straightforward and it works well.
Here is a tip to make it look "professional"
Get a ball joint and remove the brass ball insert from it (it wil just flick out) - use the resulting bit of plastic as a "knob" on the end of the rod - voila - a professional looking finish and probably quicker than it took you to bend the handle.
I keep a stock of 2-56 threaded rod and cheap ball joints for exactly that purpose.
I hope sometime I can be a blessing to you.
I am hoping to maiden the plane saturday, I already know the 15cc RCGF gas engine has MORE than enough power to fly the Katana.
Mine is doing a great job of flying my Great planes 60 stik on floats. Off snow
at 6.14 thats going to 3d like a brick, you can forget about floating around, should fly fine though
i can see this working for sports planes where the owner does basic aerobatics/fly in circles most of the time.
they just need to make this in the 15oz range so us .40 sized users can buy one, seems like its running great, good throttle response
It is a heavy engine in comparison to .40 - .60ci engines that range from 12 to 23 ounces ready to fly.
The output of the 15cc in comparison to glow engines is much less too. There is also the penalty of wing loading being much heavier. It will affect the flying characteristics of any aircraft it is installed into.
Making a light 15cc gas engine is pretty difficult to do. That is why most manufacturers stick to making gas engines of 20cc+ for aero applications.

I have about 80 flights on it.
After I get permission from him to post his pictures, I will post them on here for everyone.
There is nice weather here today so I am going to try to go maiden the KATANA V2 .46 size bird with the RCGF 15cc on it. I have been breaking in the engine and I can already tell it has PLENTY OF POWER to fly the katana.
hello guys does anybodey think the 15 cc will power my hanger 9 thunderbolt 60 size or do i need the 20cc,help please its doin my head in, witch one do i buy?
The 20cc is my favorite so far for the 60 size warbirds. You have more power to play with.
I have over ten Warbirds I may like to covert to gas someday. I have a few to build yet one being a Hanger 9 P-40, would the 15cc be enough and would it fit inside the cowling and would it have enough cooling with only the front cut out. I had a P-40 with a Saito .82 perfectly set up and it fit, cooled and flew geat with that set up (noone said it would work). Going to the 20cc an engine with probably 1.5 times the weight and about the same power might be a problem.
I haven't mess with the gas stuff yet (I just got the 4-strokers setup down) but rather than buy anymore nitros I would love to go gas in these 60 sixe birds. I am obiousely not trying to fly 3D with them but I do like my speed!!!
Dave is realy great to deal with some parts came loose inside my first engine and he quickly replaced it with a new one also the ignition unit
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!
<o></o>
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.
<o></o>
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.
<o></o>
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!

I guess he told me.
I asked a simple question and got a rude answer.
Not everyone buys an engine first and then looks for a plane for it?
It was stated (somewhere) that this engine was an attemp to replace a .60 size nitro.
I know very little about gas engines and thought I would ask before I buy instead of the other way around,
Your comment "We will hopefully get back to the point of needing to find the engine for our new plane and not the other way around." is exactly what I am trying to do!
sorry ghitt, my bad!
gasrchobbyengines, What say you??????
I love my 15cc engine, so much that I am building a Goldberg/Great Planes Tiger 60 just for it. Did not want to build a plane from scratch. Would rather have the arf but it seems they are no longer making one.
All I meant to say was that if you buy a OS .60 nitro you then look for a "60" size plane and you are good to go. With the 15cc engine it is not that simple because no one makes a plane just for it, yet. I listed the links to some planes to help out people that wanted to get into gas engines.
I feel your pain and did not mean to offend anyone.
p.s. I bought my engine from David at gasrchobbyengines, great guy to deal with. Since he installs these engines in planes for people I know he understands the frustration of "making it fit".
I have a different problem than Mr. ghitt, I want (like many others) to covert to gas with the planes I already own and have just bought and not assembled. I was asking if someone with experiance with this (and other small gassers) would work for me without the necessity of me buying and experimenting with them on my own.
I enjoy this sight and will follow it to see others successes and failers with this engine in an attempt to get the full benefit of their experiances and will probably buy one and find a fit for it.
My question stands, will this engine first adiquately fit into a Hanger 9 P-40 Cowling and if so will it fly the bird. If I am on the wrong sight for this I will move on.
Sorry again ghitt!!!
