Hello sonar boat designers
My new sonar air boat project is nearly finished. The boat is build from an old bait boat. The brains are a pixhawk controller. The motor and prop (12 x 4.5) are rather large but that seems to be a good thing. In the old design there was an 10 x 4.8 slow fly prop and a smaller motor with a power consumption of 3 A for a speed of 3 km/u. With the new prop we have 1.6 A with the same speed
Power source are two parallel 3s 1p 5000 mAh lipo's. The sonar is a Lowrance Hook4 and is perfect for this job. The boat is designed for mapping an acid lake. That's why there is no prop in the water and nearly no metal parts. All metal parts are well insulated with plasti dip. More on the project later once it did it's job and survived (end of July)
Best regards
Guy
