Castle Ice 200 HV

[HRC]

Guys,
How accurate is the data logging on the Castle Ice 200 amp HV controllers? I have 2 of them with a pair of Beast X 524 910 KV motors in a 58” cat. After a short test run I am seeing almost 200 KV difference on the data between the motors... Double checked the settings and all. The boat pulling bad to one side.
What do you think, miss matched motors or controller problem? That is a lot of KV difference.
Thanks, Dave

Ok, switched ESC and getting about the same results. Noticed the power out readings is 100% on one motor and 80.8% on the other. Thinking a motor problem?

Check you travel on the transmitter. Or the other possible is recalibrate both ESC's again. Do them separately with in dependant wiring to the Rx, no splitter or anything. I found big issues here.

Thanks, I redone everything again (3rd time) and it seems to have closed the gap between the kv on the motors this time. Still off some but hopefully doable.

Are the timing and all setting the same? Pole and kv count?

Yes Sir, the motors are now at 52 KV difference. Running on 8 s that would make one prop around 1,500 more RPM. Props are L/R X457.

I would use 1 esc, and test the rpm on each motor and compare, if the rpm is the same them check with the other esc and compare the two. This should eliminate the motors or esc's as the problems. Good luck

Thanks Guys,
Looks like I have a motor kv problem. Sent an email to Sky RC but really don’t expect any results, will see. I may run it anyway and see how it does.
Could cut down the prop on the higher kv motor…lol.

Years ago in the brushed days I went to great pains to match motors. Haven't really put any effort into it with brushless. Each motor will help the other to reach the goal. I am sure the quality of motor manufacturing comes into play in the KV consistency. Travis has done testing on some motors and found them VERY close in KV.
