This is the inverse of what I wanted to do with my tank. I wanted to make an engine that struggled to move the tank up a hill, and a tank that had a lot more traction with less wobbling from the track (if you connect the engine to the plates that should be moving the track in real life, and accelerate, you'll see that the track will skip some teeth until it finally engages). That's why the traction is up
P.S your gearbox is the weirdest thing I've seen by far xD - it shifts up but then shifts down because the engine loses too much angVel, and then up again, and it does that like 15 times until it shifts xD
Try adding more radiuses (or use mine!)

So... it needs less power? I'm thinking Wankel...

The gearbox is actually totally unnecessary. It's just carryover from when I tried to power this with the engine from my Caterpillar It's actually based on the speed of the tracks, so the shift speed is fixed. I only made it have 2 speeds cuz I was too lazy to use anything other than an if clause to get it to work xD

And did you try moon gravity?

I also looked at the code for your gearbox, and i was like, "...dafuq?"

If you would come to multiplayerpiano.com i'd explain the code

Forget it, they flooded it

I would go to that, but unfortunately I have to log off like RIGHT NOW cause my mom is badgering me to do my math (it sucks having homework over the weekend )

An I just discovered, your engine (which is pretty damn awesome, BTW) will get about as much power as this engine if you set _hi at 3950. There are some disadvantages, such as horrific vibration and unstable RPM, but it works like a champ when under load

I actually considered a V4 I built looong ago for a bus project that never made it to algobox. It worked really well, but I decided... it didn't have enough power. Big whup
