Status: offline 		A brilliant modeler in Germany has come up with a fantastic idea.....the perfect recycling of a Baby Bee .049.....into a brushless Cox .049 conversion....

He ditched the piston and rod and crank, made a new aluminum fake cylinder to save a bit of weight, and he hid a brushless outrunner inside the old tank, with the propshaft running through the old crankcase to the prop. I bet he polished up a dead glowplug to cap it off!

No more devarnishing...no more tank leaks..no more o-ring problems...no more reed replacing...no more worn out needle valves....no more expensive glow plugs!

If you simply must have the Cox noise, I am sure you could build a something for the prop to brush against....

I borrowed one picture to show the basic idea......the full info, more pictures and a video is over at:

I would never convert my Tee Dees...but I just might convert my lowly old Baby Bee, or even a well used Black Widow!...

Status: offline 		Ya I agree, but still it makes me sick to see someone gut a perfectly good engine and do that to it. I will however give credit where credit is due and that is it is kind on ingenious the way he did it. The only problem I can see, is how does he get rid of the heat? I didn't see any cooling holes except though the cylinger, but no exit holes.

Status: offline 		What a great idea! I have a couple of Chinese outrunners that just might fit. And I have a pile of reedie parts left over from my CL Mouse racing days that would make experimenting painless (no running Cox engines will be harmed in this process). Oh why aren't there more hours in the day?!

Ray, are you talking about those 2 guys you got living in your basement who keep your planes cleaned, charged, repaired and RTF?

Status: offline 		Ah ha ha so, Pigg-person,you have velly fine sense of humor - but not so velly accurate. Honorable basement residents not clean velly smelly glow-powered planes. Ptuui. They run in velly large gerbil wheel to charge Oriental lolly-polly batteries. But bad news is they not happy with Ramin noodles or Spaghetti-Os anymore. Have to provide hot dogs like at Rog's high culture Reedie races. Go figure.

Status: offline 		I think if I were to take the time to make an aluminum "dummy cyl" I would go a bit further and make it from 4036 alum and chrome the bore, make a Lighter piston and end up with a screamer version of the babe bee, I just think it is wrong to to make it look like a babe bee for cool factor but runs on lecky. geez why not just show the truth???
The guy went to alot of trouble just to look cool when he could have been honestly cool by running the original cox

That's stupid, and the work involved to get the finished product was even dumber. A perfectly good engine was trashed, and made into an insulting piece of junk with a fake cylinder.

Not stupid at all....it is a fine piece of fun engineering.

I have seen several rubber powered models with fake glow cylinders...and I have seen single cylinder motors with extra fake cylinders to simulate a multi cylinder motor.

This is simply the logical progression of the fake powerplant and one of the most ingenious ones I have seen.

I question your assumption that it was done to a perfectly good motor...how do you know it was not run out or flawed in some way?

Let's face it...the single port Babe Bee .049 is one of the least desirable Cox motors around. Most people prefer a Black Widow or other hotter and longer running reedie for flying purposes. I have 2-3 of the lowly Babe Bees m in my motor box, worn out years back. Why waste precious Cox parts rebulding a Babe Bee when those same precious parts would be better used on the better reedies?
