I like the stock tires, but they do balloon alot.
Temps rose fairly quickly on 4S with this gearing. No IR temp gun handy, but I could hold my fingers on it for about 5 seconds before it began to get uncomfortable.
This gearing does cog on startup about 30% of the time. I believe the gearing is too high and the voltage is too low.
I decided to come in and check the MMM settings. Start Power was set to low, and timing was normal.
After changing the start power to medium and the timing to lowest. Things seemed better. Cogging is less, and it seemed to not heat up as quick. No Noticeable change in power, still pretty incredible. Using the same 5 second uncomfortable finger test, I decided to stop the test run.
On the Hacker Website, it suggests this motor be operated between 5S and 8S.
My conclusion so far is, this needs a gearing and voltage change.
Let's put it on 5S or 6S and gear it 18/46.
The Hacker 11XL, being a 2 Pole Motor, doesn't like the tall gearing.
Now I need to order a MGT 46 tooth and modify it for this setup.  |
Tried Feigao 12XL with 6S and 22T Pinion/38T Spur.. no cogging at all... 8S should do you well with that motor....
