This is my first post ever over here. I'll be honest I'm not a lot into making quads or anything of this sort but my professor asked me if I could do it and I said yes, as I need this project to graduate.
So now I'm stuck with poor knowledge about quads.
The task that I'm stuck on is that there are four engines that my professor ordered. They're JC120 EVO, 12.5hp gas engines. I want make/order a variable pitch propeller for it. Can you help me find exact dimensions and where should I order it from?
The JC120 EVO detailed specifications can be seen here. http://www.hobbyking.com/hobbyking/store/__33546__jc120_evo_gas_engine_version_2_w_cd_ignition_120cc_12_5hp_8_000rpm.html
Also the quad is being designed to carry a load of at least a 100lb. Does the assembly of the variable pitch and the propellers have to do anything with the weight? Do they have to be stronger than the usual? He asked me to machine it. But honestly I think doing it in 2 weeks will be not be easy for me.
Any help will be greatly appreciated!! I can not graduate until I complete this task =(.
