Just wondering if anyone knows of where on the net you could get some plans for a RC engine test stand. thanks in advance. :spinnyeye

Yes, me too! How about it? Anyone have a plan for a stand?

Chuck

I kind-a just threw this together:

1) Old Black and Decker workmate

2) Scrap poplar 8/4 x 12 lumber end

3) Scrap 2x4's and plywood and drywall screws

4) Old wideband radio parts with S48 servo

5) Scrap wire and pins for pushrod.

6) Large engine test stand mount.

7) Dubro 16oz tank

8) A few screws and rubber bands to hold the tank and radio bag.

with radio components in the ziplock bag.

I have used this with a K&B .61 (screamer!), Saito 180 (tied the workmate to a tree and glad I did!), and last the TT 91S seen in the picture. The cool part is: To accomodate a new engine, I just remove the screws holding down the plywood servo mount, shift it to the proper position, and screw it back down onto the 2x4. I use varying thicknesses of foam to adjust the tank height.

I made a nice test stand from 2x4's, and bought a PSP adjustable test mount, and came up with a test stand I like very much.
The only thing I need to do to it now is to modify it to measure engine thrust. That will take a little planning but should be easy.

Heres a close up of the nice machined aluminum PSP mount.

Good luck with your test stand. Coulter

Are you testing a smoke system in that picture?

... or do you just not want to run out of fuel?

Yes, Its an experimental smoke system for my Ultimate. Its Much lighter than a TME.
Thats the thread after a search, sorry its so long. Check it out if you can, Its waaay cool! http://rcuniverse.com/showthread.php...smoke+pressure

Thriller, Check out these www.pspmfg.com my brother just got one for me and they look great!

Thats a nice stand, I have to say. The pspmfg sells for 80.00 I would hope it does it all.

Yes, It does it all, 049's to Moki 210's, If you have the adapter, It will do up to a 3W 240IB2, and all Radial engines. Pretty sweet

I love mine

Thanks for all the input. For me, just a simple CAD drawing or a photo of a small unit that I can build would be great. I only want to run a small motor in now & then. Certainly no need for the $80 unit, although it is cool!

Maybe I'll design one and post the results here.

Don't know why you'd need CAD drawings. I've always improvised out of 2x4s and 2x6s. I used a modular system, with a simple cutout for each specific engine. They always turn out to be sturdier than any commercial or "adjustable" system.

Here are a couple of engine module blocks.

Everything is mounted on my all purpose sawhorse. I can setup and tear down in 5 mins.

Best part is that my cost is exactly $0. All the pieces of wood are salvaged from scrap piles at home building jobsites in my subdivision when I go walk my dog.

Pretty cool plane you got there. Do you hand launch it or it has retractible gear that is not apparent?

How about this B&D work bench? Looks like it would be a natural. Maybe a couple of hardwood blocks could be added that would bolt onto it. Size of motor? Anything from an .049 to a Briggs! Use sand bags for a really big motor. You could also use it for it's intended purpose!

See my B&D workmate photos above (post 3-4). Works great. I tie it to a tree when I put the 180 on it.

LOL... No, it's a VTOL. Wings, which are not apparent in the photo, fold out prior to transition to horizontal flight. Actually, it's one of the Transformers, robots in disguise. After their contracts as TV cartoon characters expired, they retired to my backyard doing odd jobs for me. You should see the one that mows my lawn.

Quantum models offers a simple test stand for $20

Look under engine acc's.

For myself, I just cut a "U" in a piece of 1/2" plywood, bolted down a TT .91 4c and mounted the fuel tank behind on a piece of soft foam held down with rubber bands. A "z" bend in an old control rod worked the throttle. Clamped it to a bench with a C-clamp. Cost? Scrap wood.

Such a great idea, I just knew it wasn't an origional thought! What I was thinking though was to bolt on 2 pieces of wood to the table, and then screw the engine to it. Use the jaws to adjust to the engine.

Hmmm... I'm not getting you. Adjust the engine with the jaws? Like throttle? Hmmm...

FYI: the jaw control knobs get REALLY oily! What a mess... But you could fix that.

I mean to mount a wood block to each side of the bench, and screw the engine to this mounting block. The jaws could adjust for an engine the size of a .09 to a .91. Just turn the screw!

Oh! I gotcha.

Volfy,

I like yours! I have a pile of 2x4 studs left over from when we framed up my shop in the basement. I'll build it Saturday!

Looks like you've got an Irvine on the test mount?

Thanks for the pictures!!
