Yes, the meter is a simple 2 dollar ammeter measuring the amps of the electric motor. Because of the pinch the readout is not stable but still it is a good indicator, at the end when the pinch is lower the readout becomes lower and more stable.

Due the lower gear ratio with a twice as much rpm motor you also get half the torque, if you then lower the rpm to 400 by a voltage change then you also get half the torque, so you will have a quarter of the torque than an 400rpm motor. In my link there was a 420 rpm motor.

How ever many tanks you out of 1 gallon nitro.

Castor oil from the pharmacy (sold as a laxative, again because it's not digestible) works fine, though. I've been adding a small amount (about a shot-glass-full per gallon) to my nitro to raise its oil from 11% to 12% for years.

Using vegetable oil from the grocery store won't work, partly because its smoke point is too low for use inside a combustion engine, and partly because it doesn't dissolve in alcohol, which is necessary for proper oil delivery in an alcohol-powered engine.

Cool, cause that is all that I've got access to here.
