Pete or anyone,
I have always use wood props on my larger engines, but would an APC type prop be better for this size engine or does it matter? Jim

I use APC up to around 21" in diameter eventho they weigh twice what a woodie will weigh because they are very quiet and perform great. Larger than that usually means carbon. The large woodies I do play with almost always are either laminated or are modified (by me) by adding a carbon sock. Just as in the real world, a stiff one is a better one....YMMV

I generally agree with Matt. Although the seemingly small weight difference between the APC and the wood does seems to equate to a more consistent and lower idle speed on the 10cc. Shameless plug...you guys might try some of our EVO props, they work pretty good.

Has/could this engine be used in a U-Control plane?

THEY SAY THE NEW 10CC ENGINE WILL POWER ANY 46 TO 60 SIZE> LOOKS LIKE A 46 SIZE PLANE MIGHT BE TO MUCH FOR THAT ENGINE? I LOOKED AT THE 10CC TODAY AT THE HOBBY SHOP IT IS A 60 SIZE LOOKING ENGINE> NOT MADE TO GO IN A 46 SIZE PLANE ANY THOUGHTS ON THIS ???

IIRC, Hemet holds a yearly apple pie festival... visited once and pigged out. They do apple pie good..... Oh yeah, this is a forum on engines.
The folks at Horizon have suggested the performance of the Evo 10 is between a .46 and .60 and perhaps leans towards the .60 side. It is a drop in for a .46 mount.
Not sure what you were saying, that a .60 size plane is too much plane for the engine or that the engine is too much for a .46?

I THINK THE ENGINE IS TO MUCH FOR A 46 SIZE PLANE AND JUST MIGHT PULL A 60 SIZE PLANE??

For example with a .60 glow engine you need to go to at least 15cc gas engine or 17cc but most guys are going with a 20cc gas engine as it weighs the same as the 15cc and 17cc engines do anyway. So for a .40 to 50 size plane the Evo 10cc (a .61) would be about right. Most flyers like having some excess power, thus the Evo 10cc would work out nicely. The Evo 10cc engine is basically a gas verison of the Evo .60 NX which is a .60 displacement engine in a .46 size crankcase and it is a drop in replacement for many .45 through .56 size engines too, maybe even some .40 engines as well.

Yeah but.... the Escapade .61 is actually a .61 - .95 size plane or 1.20 four stroke, which is roughly equivalent to a 20cc gas. No surprise that it didn't fly it well. In fact, kudos for getting it around the pattern and back down safely.
I think Earl has it right, that the Evo 10cc will likely fly the lighter loaded of the .60 size birds but is more appropriate for .46 - .55 size.

From what others are saying, it seems that a model at 7 pounds would be a happy midpoint depending on flying style. A 3D model would need to be lighter. A scale model could be a bit heavier. I think I'm going to give this engine a go in a pulse XT 40. I use to have this plane with an EVO 46. I'd expect this 10 CC to perform real well.

Well, last night i got home from work to find a parcel from Kings Lynn Models had been delivered - My First Petrol!
I thought I'd try it in my Black Horse 46 size Extra, that turned out to be a good choice. After unbolting the Magnum 91 4 stroke that was in it, and digging out some mounts that had once held an SC52 in a CMPro Cessna I found that the Evo bolted straight in, all I had to do was hook up the 'alternate' throttle link - this model is an old hand me down that's housed a variety of engines in the past. 1 hour's work:
comparing it with what came out:
I have to admit that the strange piece of wire with a loop in the end had me scratching my head at first, then I realised it's a needle extension.
So, question - what's the best thing to use inside the tank for teh flixible clunk connection- tygon? the Viton seems a bit stiff.

Robc57,
The Viton tubing that came with the engine is fine for inside the tank. You're right, it does seem a bit stiff, but it works fine in an 8 oz. tank. I would be afraid to use it in anything smaller. In the 8 oz. setup, there wasn't much room for the clunk to move around, but I have not had any fuel delivery issues. My LHS sells a thinner walled, and more flexible Viton tubing, so I will try that in my next tank setup.

Thanks Dave. I'm using a square 6oz , the style of tank that comes with these far eastern ARTFs so it is quite long and thin. The tank, ignition unit and an 1100mAHr LiFe cell all fit into the area previously occupied by the glow fuel tank
Having dived in and installed the motor, it will be the weekend before I get a chance to run it.

PS - Tygon tubing is absolutely useless in these applications.

I have three Kadets - a Kadet Sr- a Kadet Seniorita and a Kadet Seniorita Electric ARF ( reworked a bit
Which one do you guys think would be the best fit for the little gasser?

My SR does have airlerons.
I bet the SR would be real hoot with the EVO.

A six ounce tank is about the smallest tank we have found to allow any movement of the clunk. The Viton tubing flexes more than enough inside the tank to pick up all the fuel. While Neoprene (NBR) might fell a bit softer and flexible we have found that it breaks down fairly quickly and tiny little pieces of the tubing. Please use the viton supplied.

I'll have to look into re-plumbing my #2 mechanical pump for petrol as the pump tube in that is clear, though I don't think it's silicon based.

so it may possibly be a problem for continuous inverted circuits with less than half a tank! I can live with that.

We haven't done any testing with this in a U-control application. Having developed other UControl engines with this same platform I think the internal timing numbers are to extreme to make this a good usable engine choice in anything but a U-control scale application where you could use the throttle to control the running characteristics of the engine.

Have an old U Control plane with GLOW on it and have nothing but gas engines now.
Wanted to try UC again but did not want to buy GLOW equipment for one plane.
Again Thanks

RE: New Evolution 10cc gas engine
Rodger_Russell, I think for control line that it may be useable. But I would suggest rigging up a way to control the throttle if you need to raise or lower the engine speed some. A simple fixed pushrod and clevis should do mthe trick. The engine may not have a 4-2-4 break when running, But yoiu may be able to simulate that by not using muffler pressure. With the engine running a little rich, then when it noses up it may lean out some giving a 4-2-4 break to it. But then maybe you don't fly using the two and four cycle break in some cases so it might be a moot point. It would make for some interesting experimenting though.
