I've read some about this and there's an equation out there that tells you the thrust, but it doesn't take into account for the pitch of the prop...so does anyone know an easy way to measure the thrust of an engine so I can get the most ideal prop on my plane, i have an exactly 5 pound plane with a webra 50 on her...a fish scale maybe but really how accurate could that be...maybe tie a 5 pound weight to the tail of my plane and see if it will still pull out of my hands when held in hover position? that would be a 2 to 1 thrust ratio i guess, what's an easy way here? I want to write down numbers and such, something similar to a fish scale but better anyone and affordable?

Thanks
