Need to build a test bench to run my K&B. I have a engine stand but it's not mounted to anything. What do you guys have. How do you set up a throttle control and fuel system.

Here's my Saito 150 on an American Hobby Products Jumbo stand

How do you control the throttle?

What I do is run your pushrod thru the rubber bands holding your tank..I have an Enya 120 4/s and K&B 61 they work just fine
hooked up that way.Just pull or push the pushwire,to rev or idle.Make sure all nuts and bolts are tight and stand behind the engine. I used two pieces of aluminum angle brackets mounted to plywood,drilled holes for the mount.

My brother built one from boards and spare parts. For throttle control, he used a servo, receiver, and battery. The receiver was a multiple crash victim. He doesn’t trust it for flying but it can’t cause a lot of problems where it is now.

The servo holds the throttle position steady even if it’s not powered up.

W8ye's photo reminds of when I use to bench run engines. (I don't anymore.) I had a ST 4500. I mounted it to the front of a wooden sawhorse, then sat on the saw horse for weight and let that thing go!!!!! I bet if I had wheels on that thing, I would have had a heck of a ride

Here's mine... simple, small, light and cheap... my top four criteria

Clamp it to a Workmate or work bench at the field

Cheers!

I went with something home built similiar to Jimmbbo's but a bit more elaborate.

One piece of 1/4" wood was used to build the whole thing.

I drop the test bench into a Black and Decker shop mate. THe Shop Mate clamps a piece of wood which hangs from the main board of the bench.

The motor mount is elevated on a crude wood square that has a tank mount aside it.

A pushrod attached to a simple handle acts as a throttle.

It took about 20 minutes to build with epoxy and drywall screws.

Works great, less filling.
