Hello; My son finally took down our sattelite dish, that left me with a few quarter inch thick aluminum plates, the ones that hold the big eight foot ribs together. I took one of the plates into my shop and thought what a good engine testing stand it would make. Here's the result. I know that I haven't drilled the mounting holes yet.

The centre has a pole mount that I can clamp in a workmate or just stick on a pole, The tank a\can be elastic banded (excuse the technical terms) to the centre, and the throttle wire Z-bended on (more technical terms) to poke out the other side.

I have another one that I will start cutting on for other engines that I have, what do you think? How can I improve on this idea?

Great!

I bet it sounds purty good with 'em all going.

How do you keep the props synched?

(But, seriously, folks - this is a good idea!)

I think many of us are born scroungers, always looking for something we can adapt to good use...

Should this post be in the helicoper forum? <sarcasm>

Neat concept. I have a home built stand too, but it's optimized on accomodating one engine at a time, but with an easy and flexible set up for each. It's a one foot square of plywood, with a few 2x4's screwed down and I clamp down on the case lugs. While I'm impressed with your stand, I am more envious of the number of engines. Nice!

Doc, that is a novel idea whose time has come, good job, I guess I'll have to settle for one on each end of mine.

I recently built one of my own. It is adjustable to handle just about any size glow engine. I used an old park flyer receiver, and hooked up my new Eagle Tree system to monitor the RPM's

Neat also lke the engine assortment

AND
BRJENSEN WHAT ENGINE IS THAT ALSO LOOKS LIKE AN IGNITION SYSTEM HOOKED UP TO IT Martin

just realized its the eagle tree tach pickup after a closer look still what engine??

I like the idea of the Tower 75 muffler on the ST G90 with an adapter. You should have made a longer can for the muffler while you were at it?

Don't know about the Tower 75 carb though. Their spray bar is made just like a ST except you cannot adjust the angle like on the ST carb.

The motor is a ST90 with a OS 60F carb installed for testing.

The muffler is a GMS .60 size muffler ( same as a towerhobbies ). I made the adapter. With this muffler the ST carb did the typical blubber rich at low mid range, to correct this I had to re-machine the slot in the carb barrel to change the fuel delivery profile. The ST carb now works excellent, I can run a hot plug or a cold plug, it just runs fine. I didn't measure the performance with the stock muffler so I have no side by side data, but it shows no gain when compared to another ST 90 I have with the stock muffler. This was suprising because a GMS 1.20 muffler on a ST2300 gave me a significant RPM gain.

Beings this was a new motor with low run time I am using it to do some experimenting and testing. When I get more results I'll post them in a new thread ( assuming I have positive result, HaHa ).

I included some pictures for the adapter and carb barrel
