Brodak Baby Clown

On the first flight, the plane would have been able to do the complete pattern except that I did not properly adjust the pushrod and there was not enough down elevator.

It was also a bit windy for a small plane – 10 to 15 MPH but it performed surprisingly well.

There are a number of configurations in which the plane may be offered:
ARF with or without engine
ARC with or without.

Fell free to contact me [email protected] regarding any technical queries about the plane or engine.

For information about price, configuration and delivery dates, please contact Brodak Manufacturing.

This little plane promises to be lots of fun!!!!

I'll second that... it's a heck of a nice-looking engine. Might even make ME want to fly 1/2-A!

Looks like the one-piece molded nylon 1/2A engine mount Brodak offers. He includes it in his 1/2A primary trainer kit. Originally available on Sterling 1/2A models. I have one on a Baby Ringmaster Bipe across the room. Really nice unit. It traps a nominal 1/4" fuselage and is held on by two through bolts. The engine bolts through the nylon firewall molded in. Trivial to install, and totally fuel proof. A major improvement over the old plywood firewall and balsa blocks. I use nylock nuts on the back so they don't vibrate off. The hole pattern on the old unit is for the Cox reed valve engines with integral tanks. I would bet Brodak's 049 matches this pattern which is pretty much industry standard. That way people can use Cox engines they have if they don't want to by the Brodak 049. And he doesn't have to develop a new nylon mount for his new engine. A win-win situation, IMHO.

The new engine looks *awesome*!

Edit: Just looked at the nylon mount. The one in the picture is functionally similar, but looks like a different design, so probably a new part. The old one has a V groove in it to trap the landing gear between the firewall and the engine backplate. The part shown seems to do the same.

BOY!!! An .049 that we can fly! (even Love, if the price is right)
Another 1/2A 'squashed GeeBee' is in the works...A Titebond bottle body serves as cowl, and...and...I'm just excited, guys...

I bought an engine almost exactly like this on eBay a few years ago, click on the link below to see photos. It is a CS engine manufactured by "Shanghai CS Model Equipment LTD" and is .075cu.in. displacement. I have not run mine yet so cannot commemt on performance.

Yours looks good compared to the one I bought. The castings looked like a case of leprosy and of course it barely runs.I was amused that they used a bright aluminum paint to make the whole mottled mess look shiny.

Yes of course that is a nylon 1/2A profile mount. How'd they get the radial mount mounted to a BEAM engine?

1) Supply the engine with two back plates. One "normal" as presently comes with the engine, and the second with the radial mount as part of it so that the engine could be converted easily to radial mounting. I can see problems because the back plate screws in and the threads are going to be random. It could be difficult to make this so it would tighten up and always end up in the same pattern. But...if this were done, then I would suggest that the mounting pattern also match exactly the mounting pattern of the cox Baby Bee or some such so the engine could replace the Cox engine on an already existing plane. When Brodak came out with their 40 using a proprietary muffler mount and venturi, this was a major error.

2) This would be an easier solution. Make a radial mount with the beam mount cast into it. Bolt the engine to the mount. And then you have a radial mount to bolt to the firewall. Again, put screw holes in this that match exactly those of the Cox Baby Bee. One could even make a tank mount this way--not for this plane, but for others where a Baby Bee or Black Widow would normally be used.

Just an Old Advanced flyer with a mule that has gone blind.

How does the Brodak .049 compare to Norvels or TD's in output and operating characteristics?

BTW, guess who designed that mount <G>

Anyway, that coupler to the new Brodak engine is great! Very nice idea, and beautiful execution.

I used a bent piece of 1/16" aluminum to mount my PAW 55 on my Baby Clown (not the ARF by about 4 years). As such, I can switch back to the Holland Wasp at any time.

Very simple beam mounting is all it takes for that size engine. Extremely light! and Adjustable for thrustline (especially in a crash). If you are the nervous type, you can use 2 pieces back to back and catch all 4 holes, bolting through both of them with the engine.

Hi JIM,
How can I send you an email? The forum link doesn't work. Thanks;
