I have an FE question swordfish pro 300

[klbo]

I'm running a swordfish pro light 300 castle creation 2028 on 10s it's running 168 A 27,000 RPM for two laps then it falls off to 92 A 20,000 RPMs what could be causing this? Timing is set to auto voltage does not drop

What packs are you running, exactly. Brand, name, mAh capacity and C discharge rating. Exactly what boat? What prop? We need more information to be of help.

Central marine fountain 58 10s2p Revo 5000 420 70c graphing lipos brand-new Octorara 455x boat goes out just fine runs two laps drops about 5000 RPMs and stays there for the rest of the run comes in stone cold

is 50*c considered stone cold? If i pick up a stone from my yard its probably closer to 50*f

I would guess that something in the controller is causing the issue. Set the timing for 10* advance and see if that helps, the auto advance may be malfunctioning. If this does not work, disable the LVC and try again. BUT - time the run for two minutes and bring it in. (Be careful if you run without the LVC on, either time your run or run a set number of laps.). Let us know what you find out.

If you are averaging 168 amps on 10S for six laps or more the electronics are not "stone cold" unless the starting and water temps were very very low. You really should invest in a temp gun to quantify the temps. Don't feel bad, too many on here are 'role models' by being very cavalier about reporting temperatures of their electronics. "Ice cold", "cool as a cucumber" and similar phrases are meaningless and defy the laws of physics - assuming the run reports are accurate and particularly in the summer.

I set the timing to 16° advanced lowered the low-voltage cut off to 3.0 ran much better but still seems to slow down after the first two laps ESC came in at 109F motor 86F

[klbo]

I have a temp gun and temps were around 99 for that run and it only drew 168 A for two laps then drop to 98 A for the rest of the run

It sounds like LVC is kicking in because you have the wrong cell count. Is the esc set to 11s? Make sure it's set to 10s and not auto. Are you running 10s 5800 or 10s 11,600mah? Also if everything is cold then you need a bigger prop.

I hear 10 beeps when it turns on but I'll set it for 10
and it's 2- 4s and 2 6s 5000mah batteries for a total of 10,000 mah 10s2p

For some reason I saw 5800 packs but if the boat continues to run the same after you try some different settings then I would say your esc is not working correctly and time to try another one to see if that's it. You might also need to cut the shrink wrap of the motor to esc bullets to make sure you don't have a bad solder joint. I had a 10s mono stop after 1 or 2 laps and turned out that one of the bullets on the motor was hanging on by 1 thread.
