Is this a cox engine?

to the forum, @Abraham996!

Yes, as Jacob mentioned, it is commonly referred to in the engine modelling community as the Testors "pipe bomb" engine (because of its simplistic unusual appearance). It came with their fleet of plasic ready-to-fly airplanes.

A few here have adapted their custom fuselages to be able to secure the engine properly in place on their balsa control line aircraft. (A few posted threads on their adventures here in CEF.) They are actually decent engines. Some had a poor needle valve mechanism, making adjustment difficult.

Testors used the engine as a basis for their 8000 series separately marketed engine, came with an integral plastic tank with mount holes to fit the Cox tank engines firewall bolt pattern. It could outperform the Cox .049 Black Widow engine (See Sceptre Flight Engine Test archives.)

Abraham,
Welcome to the best little engine website on the internet!


George,
I love your Swordsman. The green you chose is enviable! I've seen your particular plane somewhere some time ago, but I can't remember where. Between the color, the canopy, and the pilot this is one unique take on this model.

I don't think I saw it here or on SH. I feel like my first sighting was several years ago. While where isn't important to this thread, it drives me crazy trying to remember. I suspect I saw it as part of chasing down the 1/2A plans for the flat plank model Testors designed to sell their Testors 8000 integrated tank engines. The name of that model escapes me. I think someone else blew up the plan for a .15 engine later (that piece I think I saw on SH).

Can anyone remember the model I'm thinking about? It had a long root chord, a large tail surface, block nose on either side of a wedge-shaped profile fuselage...no landing gear. The tapered wing was square across the LE with small wing tips and the TE was tapered to the back. The tail was a swept rearward LE stabilizer and straight edge TE elevator. That plan is the point of my post as it was designed for a tanked "Abe's engine."

Edit: Found it...the Ambush!

Jim, thanks, the Swordsman is painted in Pactra Stinson Green dope, of the last 2 oz. bottle that I had. It is a very useful color, redid my brother's Li'l Devil hollow log back in 1971 with Stinson Green fuselage and rudder, SIG Orange wings and stabilizer. It also graced the tissue of a Comet 12 inch Spad XII.

It is a slightly deeper green than John Deere. I suppose one could get it in Randolph dope, but dope has become almost non-obtanium giving way to other finishes.

I think perhaps we are the last generation to be familiar with the wonders of butyrate and nitrate dope, cellulose glues such as Ambroid, Sig-ment, Testors, Comet, and lastly, Duco, which is no doubt on its way out.

Whilst packing, found a round plans carboard container that I squirrelled away rolls of Hobby King plastic covering, perhaps the last of decent heat shrink model airplane covering.

Nice George, I like that color too.  I had Stinson Green dope at one time many years ago.  I have forgotten what plane I used it on but I doubt that it was attractive as yours.  Maybe one of my Scientific hollow logs.  

I have a supply of Top Flight Lustre Kote spray similar to your (Edit - whoops - roddies Pacta spray) (another thread) that I have been guarding.  I haven't used it for years but I keep it anyway.



Amen, in a sad way:

"I think perhaps we are the last generation to be familiar with the wonders of butyrate and nitrate dope, cellulose glues such as Ambroid, Sig-ment, Testors, Comet, and lastly, Duco, which is no doubt on its way out."

The pipe bomb engine is a horribly maligned and belittled little engine. Carl Goldbderg should have made an engine mount for it like he did for the Cox postage stamp engines. They make power like a good Bee engine, and I've made three or four planes specifically for this engine.

Now, if I ever ended up buying a 3D printer, one of the first projects I would do is draw up and print out mounts for the Testors engines. *Hint* *Hint*

The GB EB-1 Engine Mount (cost $0.69 back in the late 1960's) came out in the early 1960's. Then, Cox came up with the postage stamp engine back for their RTF planes, and he saw a golden opportunity to make these donor engines from crashed (many had a 1 time flight) reusable in his kit planes.

The pipe bomb engines didn't come out until later. By then, C/L was in its decline, why there wasn't the market advantage to make such.

I suppose one who had a CNC printing machine could make an adapter or special back for these engines, but it may not garner the sales, since the Coxes abound in comparison.

But, I enjoy reading the threads here about how the mounting obstacles have been overcome for aircraft use.

Nice Swordsman George, The color, decorations, and engine just work!!… I’ve got his cousin, Stuntman 23….. I really need to find a place to try it out….

I sent you a PM.
