More engine building videos please. That lot were fascinating.

A thought regarding propellers. Often with free flight models, low pitch propellers (3", 4") are used so that a larger diameter propeller can be used - giving more thrust. But since your motor is turning only 6000 rpm at best, low pitch propellers may not result in a flying speed greater than the stall speed. On a 4" pitch prop 6000 rpm is only 23 mph and 3" pitch is only 17 mph. A Cox .049 on a 6x3 might be doing 15,000 rpm. But even at 12000 rpm the "pitch speed" of 34 mph would clearly be above the stall speed of the model and thus viable for flight. Since your motor seemed to like larger props, perhaps you could find a 6" pitch prop and give that a go ...

This was very therapeutic to watch!

A 7x6 hyper balanced wooden prop would help.

Great stuff! You can't argue with flight proven hardware.

This is myone and only goal with home machining: Building practical tiny engines. You're livin' the dream! Once I get done with my 71 C10 project I might start buying up some tooling to start down this path.

Those glo engines will give u grey hair trying to get em runnin right

Great job man! It seems like it needed more air fuel. Rotary valve or reed is the way to go. Maybe test crank case pressure as well

For normal free flight this engine will do great for that size model

@flynat-rc Ай бұрын

yes, I think you are right, ports arrangement, should be improved...in any case you made a great work...very nice

Most guys I know run 35-40 % nitro for those small engines. Have you ever tried hotter fuel? Wonderful machine work excellent skills.

@flynat-rc Ай бұрын

I think you should try a smaller prop, for exaple 7x3,5...my little 1,5 cc cipolla junior used that one and run a lot

@JellyFishMachine Ай бұрын

I thought the same, i tried a 6X3 but it barely ran and was super sensitive to the needle. it actually runs the best, and fastest(?) on the 8X4. i suspect it's due to the port size and arrangement, it can't breathe well enough to break past around 6000 Rpm

What wingspan has that Diamond Demon? 49" or did you scale it down a bit?

it's normal scale, 49"

@@terrymoorecnc2500 My supposition is that it's not got quite enough transfer port area - it was also designed in the late 40's, with a long stroke and fairly heavy rotating assembly. it actually turned faster, with a larger prop lol. with the turbo plug it barely ran on a 6X3. I was thinking of making the transfer ports bigger and reducing the weight of the piston assembly but i think i'm gonna put this one on the shelf for now, i've got lots of other things i want to work on.
