RC Plane Stand that can be used to test motors?

I'm looking for a better/safer way to test the motors on my Twinstar II.. has anyone used this HobbyKing stand..

I'm wondering if there is a way i can strap the plane to it and crank the engines to test..

What method/stand does everyone else use for testing.. curious..

Thanks

Test.. what test?
I test my motors in my workspace.. then never give them a second thought.
These are not IC engines, they either work or they don't :-)

Well recently I was using a new battery pack (likely unrelated). During the flight one of the fronts if the motors flew off. EDIT.. i think it was just a broken prop mount bolt.. though the other half is embedded in the hole..


I figured maybe pre flight or like now after installing engines a full thrust test with the blades on could be useful beforehand.

My ts2 doesn't have wheels so the stands at the air strip aren't that useful

Put on the prop you want to test, plug a watt meter in, hold the plane & throttle it up (easy as that)

I had a mishap inside once where i accidentally kicked the throttle.. for inside testing i figured it would be safer to strap it down

That stand is basically just a plane cradle and it is to light to be holding back your plane unless it also is secured to something solid.

Yeah, not heavy enough on its own, But no reason you can't strap your plane to it and then strap the stand to a couple bricks or something.

Do us a favor and NOT refer to a "MOTOR " as an ENGINE .
Then throw a rope around your tail and stab a screwdriver in the ground to hold the plane back or tie the rope to your work bench or something. ENJOY !!! RED

I had not thought about running up a motor while plane is in the stand till I saw your post. These are easy and cheap to build and I think would do what you are asking?

The pipe comes in 10 ft lengths, then cut to desired size. Lay out the design to determine the number of elbows and tees your going to need . 1/2 inch schedule 40 pipe and 3/4 inch foam pipe insulation will complete the list.

Any ideas what is being used to keep the elbows together, at least on the upper part.. i'm assuming maybe some welders glue or CA Medium in the joints to keep it tight for forward thrust tests..

I see in the one photo maybe two 5" bolts at the front with washer/nut combos it appears, then covered in foam for that part..

PVC glue, on the shelf next to the PVC pipe, dries almost instantly on contact with the mating piece. You will also find a ratcheting plier style cutter in the same aisle.
Any good home improvement or hardware store will have everything you need.

Thanks.. perfect..
I suppose if PVC glue holds well.. no need for the bolts then.
