ENGINE TEST STANDS

PSP Test Stand (Metal)
American Hobby Products "Mighty" Engine Test Stand (Wood)

This engine test stand, is from PSP Manufacturing. The kit was ordered from the Internet (An Ebay auction purchase).

Delivery was fast. Really high quality items were in the box when it arrived. Everything needed to use the test stand was in this deluxe kit. The list:

The Test Stand Itself
Sullivan SS-10 Fuel tank (10 oz)
6 feet of high quality silicon fuel tubing
2 2"x12 wood screws
4 small screws for small engines (0.07 CI)
Allen Wrench

	We use a Workmate to hold fixtures for testing and breaking in engines less than 3 Cubic Inches. A mounting board was needed for mounting the aluminum engine test stand base to the Workmate. In this case a 2x10 board 47" long was used. The board is long enough to allow the use of most any tuned pipe, even the excellent Macs Quiet Tuned pipe on the SupreTiger 4500 (2.76 CI). A mounting rail was glued with a tite-bond adhesive and screwed to the base. In this case, the mounting rail is laminated from two pieces of wood. The rail fits into the workmate top clamps.
	The wood was sealed with sanding sealer and then coated with white latex primer. The primer coat was sanded smooth. Then a final coat of Century 21 epoxy white paint was sprayed on and allowed to "dry" for two days (epoxy sets). This helps seal and protect the wood from the fuels.
	The mount stands were both removed by loosening the allen screws and sliding them out of their slots. The base was secured to the mounting board using the supplied wood screws.
	This is a Super Tigre 2000 with a three blade Menz 16x10 prop turning at 10,400 RPM. The test stand can safely handle quite a variety of engines.
	This is a YS120 4-stroke engine mounted in the test stand. The throttle control is really great, is easy to operate, and holds the throttle position with a knurled plastic knob and threaded screw. A ball link is provided with the throttle cable. A really nice touch.
	The left side of the engine. The tank mount holds the included Sullivan SS-10, but the DU-BRO S-16 and S-12 fit as well. This way, one tank is set up for gas, one for the four stroke PowerMaster 20/20 and Morgan Fuel Cool Power 4-Stroke (15% Nitro) and a third tank for the SupreTigre fuel (low oil content) and FAI (no nitro)fuels. For the YS engines, we may have to use stiffer wall fuel tubing and wrap the tank with strapping tape (like we do in our models) due to the fuel pressures involved (9 - 12 psi).

Overall, this test stand is now our favorite test stand for engines with mounting lugs. It can handle a wide variety of engines and is a high quality, strong unit. The throttle control cable and position lock are a nice feature. It does, however, come unscrewed as the due to engine vibration if you leave the thumbscrew loose. They have changed this on their newer design. The tank mount is rugged and simple.
It costs more than the wood and cast powdered metal styles that are available, but this unit can handle a wider range of engines. Changing engines is fast and painless.
We want to thank PSP for allowing us to review their great product. We've bookmarked their site for future purchases.

An Enya 120 in the mount. Real smooth power band. We use a remote glow plug attachment when this is on the plane for safety reasons.

This is the OS 0.61 Heli engine, which had carb problems initially. Attaching a fuel hose to the carb and blowing air into the fuel inlet as the throttle is moved should allow air to pass into the carb. No such luck on this motor - no air at any throttle setting. Cleaning up the 7H OS Carb in the ultrasonic cleaner and readjusting the three settings made this engine run like a new one - maybe even better. What a smooth running engine.

	This is a Husqvarna 4.4 Cubic Inch engine mounted to the Mighty Engine Test Stand from American Hobby Products (781) 944-8316. This test stand is rated for up to 5 Cubic Inches, 40 lbs of thrust and a 24-inch propeller.Note the concrete pavers used to hold the test stand. Also, four long spikes have been driven into the ground at each of the test stand corners.
	This engine is spinning a 26/12 Glasner propeller at 4700 RPM on no nitro glow fuel. The prop is 2-inches larger in diameter than recommended, but worked OK. A Toyota starter has been converted for use as an engine starter and is safer (for the operator) to use than a leather glove. This engine moves LOTS of air!
	This is an A&M 3.2 Cubic Inch Gasoline engine on the same test stand.
	The powerful Webra Bully running Morgan Fuel's Super T fuel idles at 1800 RPM and tops out at 8700 RPM with a 18x8 propeller. Not bad for this 35 cc glow engine (2.1 CI). This engine stand can accommodate many different engines.
