The best you can get in accuracy is with Survey grade GPS receiver ($30k) and that has 1" inch horiz and vert. and even that is too much tolerance for our 1:14 scale trying to level with. The idea is great though. Maybe use an accelerometer instead?

So is there a way to make a way to keep the blade level with some kind of gyro. Like a drift car gyro. The thing I see is how will the dozer know where the blade is.
