So I have done a few mild mods since I got the boat. The most latest was installing a UL-1 motor and a very impressive cooling jacket I got from OSE.
Then I decided to to go with a hotter prop for this boat. After reading several threads and based on the availability, I ended up purchasing the sharpened and balanced X447 prop.
I installed the prop knowing I have to monitor the temps at the first few runs to make sure everything is ok. I started out with my older flightmax 5000 30C batteries I had kicking around. First off this prop made the boat go like a bat out of hell after a couple of minutes of run time I brought the boat in and checked for temps. ESC and motor were both around 100 degrees so was the battery. So that built some confidence in me and I changed the batteries to Gens Ace 5000 40C. Well I think that did the job, after running around a minute, the boat stopped. So we brought it in and immediately smelt the bad news
The ESC was done. The wires for the motor and the negative wire to the battery were just completely unsoldered from the board and sticking out of the ESC. Also burnt smell all over the boat and marks on the rear of the boat where ESC sat.
I guess I misjudged the fact the higher C rated battery can produce more current for the load on the motor. So much that ESC could no longer handle it. Thanks for a few tips on this forum, I cleaned up the Hull (although the sting is hard to get rid of) checked out the hull once clean and saw no visible damage. Please have a peak at the attached photo and tell me if it looks ok.
Also as a side note, I bought the upgraded trim tabs for the boat but I am having a hard time figuring out how to adjust it due to the design of the rear of the boat. Any advice on how I can work around it? I was thinking of making a small hole on the trim tab and turning the screw upside down. However I dont know what kind of effect the hole will have on the boat handling.
Thanks for reading and any advice you can provide.
