Today was a boat test day and we made test runs with all of the boats.
Rigged Insanity: We adjusted the strut and moved tbe batteries about 2 inches further forward. That got the boat running nicely but it had a big tendency to turn right. It turns out the skid fin was not aligned properly. Once we straighten that out then the trim was good and the boat ran nicely. I must say it turns really quickly even at speed. We ran with a GrimRacer 40x57 3 blade prop and it hit 43.6mph.
Pay-n-Pak: Was tested with the Proboat motor, ETTI speed control and a X640 prop. The water was pretty rough during this test and we got to about 38.4mph. It was airborne quite a few times but stayed flat and didn't tend to flip - but it sure got banged around.
Atlas Van Lines - I think we need to change out the ProBoat speed control for an ETTI 100 amps speed control. We run both the Oberto and the Atlas with Proboat motors on Graupner K45 props. The Oberto has the ETTI speed control and runs just fine. The Atlas has the ProBoat speed control and after about 3 laps it shuts down briefly then it will run again. From the data logger we are getting pulling about 55 amps, and I think we are getting thermal shutdown from the Proboat controller. Other than that the Altas is running smoothly.
(Update: The Oberto now has a UL-1 motor and controller so the ETTI controller is now in the Atlas. This should fix up the shutdown problem)
1990 Oberto - Smooth and pretty fast. With better
