It will run guaranteed. Original Cox engines are nearly indestructible

@TestECull 4 жыл бұрын

Yup. P.much the only way to kill one is to neglect socket resets and shatter a piston from excessive play between piston and rod, or by using too short of a bolt to hold the prop on and shearing the crank off right at the drive washer. And thanks to Cox International even these failures aren't the end of the engine!

Remember - there is ALWAYS a good reason to make such a video even if you don't have one personally - there are plenty of others outside (myself included) who APPRECIATE and learn something new from such videos. So keep posting your engine videos no-matter what :)

That engine came from a Cox P-40 airplane! Rather rare cylinder as it is marked P-40! That’s a keeper I have hundreds of cylinders but only 1 marked P-40 !

@mgpmbass3616 2 жыл бұрын

The P-40 came with an .049, not the .020.

This is great. A real feelgood vibe about getting this going. For a real vintage Cox like this one could imagine one of those long nosed low wing free flight jobs, with a profile pilot figure (helpful vertical stab) in comedic style.. Nice bright colours for the plane. Perhaps a flying scarf for the pilot, moustaches also a must.. Spoked wheels? Wheel spats? Nice one! 🌟👍

I had a buggy with a COX 0.049 engine when I was a kid. Cox made a recoil pull starter that I added to the engine, eliminating the need to wrap a string around the output driveshaft/worm gear/cooling fan/starter sheave. I also added a larger aluminum heatsink onto the cylinder. The engine had a little spring-steel cylinder that acted as a throttle by covering up part of the exhaust port. It had a little zig-zag wire attached to the cylinder with detents allowing the engine speed to be controlled. I was always amazed at how slow the engine would run. One thing I remember, in particular, was how the 6 VDC glow plugs didn't last very long at all.

@electronron1 3 ай бұрын

I didn't know they had 6 volt glow plugs, I always used a 1.5 volt battery that was about 1-1/2 inches diameter and about 6 inches tall.

Criminy! 12,000 rpm! Those things scared me as a kid, but I may drag out my old .049s from childhood for a run. I think i g ave an un-run .020 as well. Thanks for the memories and inspiration!

The 3 blade prop and the p40 marking is a dead giveaway to me that it came on a Cox P-40 Warhawk when new. Looks just like the engine that came on my old P-40. Great work on the cleanup.

Oh, very good information. I thought it might have been on a tether car.

@johnkelinske1449 6 жыл бұрын

They put them on a couple, but I think they had pusher props on them. The cylinders were blued from the factory. The old Baby Bees used to have the "Thimble Drome" marking on them, which goes back to Leroy Cox early days with tether cars where he started out. Is the little rubber "donut" o-ring on the intake inside the tank? These are usually deteriorated and should be replaced on a rebuild. They tend to leak otherwise and cause you all manner of headaches. Good job!

A mixture of methanol, nitromethane, and castor oil was what came in the Cox glow fuel I used in the 1970's. From Wikipedia: The fuel used to power the engine is called Model Engine Fuel, a mixture of methanol (70-40%), castor oil (20%) and nitromethane (10-40%).

I have that exact engine on a Cox P40 Warhawk plane made in 1960 that still fired up last time I ran it (about 30+ years ago!) what are you using for fuel? Cox glow fuel has no been available since around 1990!

@dmrcflyr2 Жыл бұрын

Honestly I don't recall what fuel I used. Obviously is was just some standard glow fuel. I know I didn't buy anything specific for this engine. Look at my 1/2A playlist I am sure that I mention the fuel I used on one of them.

how do cox engines get the fuel from the crankcase to the cylinder head? I couldnt see any transfer ports

@johnkelinske1449 6 жыл бұрын

It's a reed valve engine, the venturi intake is on the backplate. Baby Bees have a single cylinder transfer port, others like the Black WIdow have two.

@diestimmeausdemnirvana8286 Жыл бұрын

Like all 2 stroke engines do: Carvings in the lower part of the inner wall of the cylinder. Actually in these small engines these ports are even hard to see.

Oh HECK no!! ONLY steel parts should should be in contact with CLR. Do NOT immerse AL into it. I do not use it unless the engine is completely disassembled and steel parts can be isolated and soaked in it.

After removing the steel parts from the CLR they need to be rinsed well with water and immediately oiled and kept oiled. Otherwise surface rust will begin right before your eyes.
