Hi fellow modellers
An update and a request for help
Normally I build a model boat because I have the urge to expand my fleet of freelance boats. However, my current build was not a planned project, rather a case of " necessity is the mother of invention".
The campground I sail at, a short 10 minute drive from home is up for sale and if the new owner chooses to deny me sailing time I will be forced to drive 30 minutes to Long Lake. Up until a few weeks ago Bryon and I would check the web weather report to see if the winds are acceptable for power boats.. We have become frustrated with the inaccuracies of those reports and many one hour return trips were recorded with no sailing. A solution was needed and fast.
I am not a sail boat enthusiast so that was a no-go. However when viewing Youtube I happened to stumble onto a large 40in PT boat planing over choppy water. That was a Eureka moment for me. Instead of pushing a displacement hull into the chop i would skip over it. I purchased a 40 in PT boat hull from a friend. i had seen this model perform in the past. It was ready to sail but was updated with a 2.4 Ghz radio and RX. I decided to build a second freelance Police boat.
I sailed the boat this morning, however I was surprised to witness a motor cutting out after a minute or so at high speed, after a few seconds DIW back to power. The motor did not appear to be hot. I brought it home and bench checked the power train. Under no load the motor works fine. It may be a problem of mis-matched components. The motor is a 8.4 volt Robbe 600/24 running at 18K. The battery is a 7.2 volt pack ( never noticed before because i assumed it was the same as the motor ) and oddly the battery charger is 9.6, another potential problem. The ESC is the old Robbe Green unit.
I assume the proper voltage to the motor would result in more speed but I doubt it would cause the motor to be intermittent. Anyone have a thought on this problem ?
Cheers
John
