I just saw these DF95 tuning gauges loaded onto Thingyverse (that means you can download and print for free). These gauges are a good start for getting a balanced boat. You will need a 3d printer or friend (You have one) with a printer. Let me know if you have trouble seeing the files, there’s a Powerpoint on how to use them too.
