Can you direct me to a site with details on building a motor test stand with thrust & torque measurements?

I just ordered a Little Screamer, do you think it will have enough power for a Foamfly Frog or a Bantam Bipe? (heh-heh)

I have two of them, one in an Icarus Shocky and one in a Convair Pogo. Both weigh around 9 or 10 oz with batt. pulls both vertically forever. Very happy with them.:D What would your planes roughly weigh?

Both weigh less than 10 oz, but they don't have ailerons.

I have some photo's around here somewhere showing a couple of different thrust stands. I'll see if I can find them.

If you want something premade, Balsa products sells a thrust stand with or without a scale. Combine it with a Tach and wattmeter to gather more data.

Can't help you with the torque measurements (I tried one set up, with only modest results), but thrust we can do with considerable accuracy.

Here are various pictures of the **** Hanson/Dr Kiwi thrust stand.

Here are a couple of links with more info on the "thrust stand" topic.

Here is my version of the thrust meter. Got the postal scale from Office Depot.


The servo tester does make it better than fooling with a transmitter, which I used till I found the tester. I am limited to 12 inch props at the moment, which can be changed when needed.
