LPETools - A new tool, by Nico71

After having released some other tools like the TTools and WinchTools in the past, Nico71 (Nicolas Lespour) has now released a new tool for the LEGO Technic hobbyists.
LPETools stands for LEGO Pneumatic Engine Tools and allows to calculate the maximum power and average torque obtained from such engines, given its characteristics like: type and number of cylinders, pressure, crankshaft radius and rod lenght, number of switches  (with or without modifications).

If you ever wondered how much power you can squeeze from such motors.

Wow according to this some of the engines from LPE power can generate well over 100 watts of power!

make the stroke longer and you get more as well. I have a 60 degree V with 12mm stroke design I am working on it fits models much better than the 90 degree at least in smaller scale. Great tool. trouble is making a drive train that can hold the power of these things.

Hello, thanks for the featured !

For the angle of piston and crankshaft : at the moment I choose a simply way to calculate : division. 2 cylinder is 180, 3 is 120° etc. But for 4 pistons for instance, there are 2 widespread distributions : 2x180° and 4°90°. The performance are not the same so for the next release, I hope to implement this.
