RE: NEW to FE? BUILDING a boat? What's a LiPo? Look Here FIRST!!
PRE TESTING
When the hull is finally completed with a well suited power system it is very important to follow these next few steps.
After choosing the most conservative prop for a given setup, charging the packs and placing the hull in the water run it for 45 seconds. After the 45 second period, bring the hull in and note the temperature of the ESC, motor, and cells. If all components are well under 140F/60C, run the hull for yet another 45 seconds. If temps are under spec run for another 45 seconds and continue this pattern.
If the temperature exceeds the safe limit, one has either exceeded the maximum allowable run time or is using too large of a prop or a combination of both. Reduce prop size or run time.
Following these simple rules will greatly increase the odds for a successful 1st or 100th run.
For even greater safety, make only a few passes totaling 20-30seconds and bring the boat in. Checking temperatures can be a pain but will save loads of money
