Great work. Unbearable music. Perhaps even a bit of AI commentary would have been better than the death metal. Awesome video nonetheless. So much content and talent that I have to watch it again!

You think this is death metal? Its mild rock at the most. Their name is Dream Theater

Marvelous work. I tought a radial engine 3 stoke was not possible. Due to the canceling effect of the pistons on the crankcase not contributing to scavenge the fuel properly

it kinda sounds like this helicopter from one of my favorite shows Air Wolf
@johnnyappleseed6415Ай бұрын
As these engines require positive crankcase pressure to operate, I can fully see why you had to incorporate a supercharger...

Ventom cylinders/pistons and high compression heads are the way to go.

Thanks for sharing! ~25 years ago I was flying U-control 1/2A with 3 up combat with a super simple basically indestructible home brew planes with 049 black widow motors. My third black widow motor I got was a dud, would barely get 14K rpm, where my other two 049's was in the 18K rpm range with 10% nitro, thimble drone 5x3 prop. Troubleshooting the dud, a friend showed me how to lap sand the case at the carb/tank mount (1500 grit sandpaper put on glass and sprayed with wd40 and sanded in a figure 8 pattern), it knocks off the bulge of the 4 course carb/tank mounting screws (a black sharpie put on before the sanding will show the progress). This did not seem to help the dud motor,,,,but I got an idea. Why not try it on where the cylinder screws in (effectively changing the timing). I passed my idea by a buddy that road raced the two stroke Yamaha RD400 (and was a auto/diesel mechanic), he said I should raise the exhaust ports (so not remove material, but add to it), so I made a 0.010" base gasket, this made it a super dud motor, lol. To scientifically gauge what I was about to attempt I measured the height of where the cylinder screws in to the case (see picture of the red lines where I measured - from case to where cylinder screws in), I call this deck height, my normal two good motors was 78 thou (0.078"), the dud was 84 thou, instantly a big grin appeared. With the precision these cox motors are built to, wth was going on with this spec, 0.006" too tall. I started by taking 5 thou off (glass/sandpaper/wd40, same as I mentioned above) and retesting, result was better, another 5 thou, even better, another 5 thou and was getting hard to start. Then I thought why it was hard to start, hmmm, way to much compression, perfect, the head gaskets were 5 thou, I can compensate with head gaskets, so for every 5 thou I removed from the deck, I added 1 more head gasket. After continuing this process a few more times (I went down to 53 thou from 84), it turns out, 15 thou off the good motor (was 78 thou, now reduced to ~63 thou with 4 head gaskets (1 original +3)) was the best. Results are with 10% nitro, Thimble Drone 5x3 balanced prop and plastic reed valve. Bone stock good motor with 78 thou deck height = 17-18K rpm, Bone stock dud motor with 84 thou deck height = 14K rpm, Best was reducing to ~63 thou deck height (on all motors), with a total of 4 head gaskets, 25Krpm and one hit 26Krpm. A gain of 7K rpm! For pictures and discussion, google search coxengineforum black widow tuning

In rewatching this.... question: did the two props totally and equally cancel the others' torque and p factor? In another KZfaq video out there, the motors with their props are set on a kitchen scale to measure thrust. I mean, they're not mounted to anything. The props were zooming and the assembly didn't move a bit. Did this really work for you, too?
@christiansprojects-cgmanuf14262 ай бұрын
Yey, I think so. I have never measured resulting torque or p factor. But on the airplane, I set the side thrust angle to zero. The plane takes off perfectly straight without any rudder input. Also, while accelerating from slow flight, I do not notice any of the usual warbird tendencies. It really behaves more like turbine powered.

Very cool project! I'm curious as to why all of your connecting rods float in the main con-rod carrier. Doesn't one con rod usually serve as a master con-rod to control the rotation of the con-rod carrier?

How much static thrust? And at what power?
@christiansprojects-cgmanuf14264 ай бұрын
I have never measured the static thrust but it will be somewhere around 8Kg, maybe 9. Power is 2800 Watts. So not very efficient but this was never the goal.

GFY to the commenters regarding the music READ THE AUTHORS COMMENT (OVER 4 YEARS AGO) FFS - REAL viewers are here for the engineering excellence - the music was just a bonus. Also GFY to the so called experts (RE gas engine etc) - its not their project. I think it is all due to jealousy. AMAZING EFFORT - All the best!
