not sure

[jlr3rd1]

first run with lipos, in my blackjack?? the boat went about half way round the lake and stoped?? when you squeeze the trigger you could hear the motor turning but no power, barley got back to shore:) when i opened the hatch there was a lilttle smoke around the left battery plug???? but out of the water the motor turns fine???

First a few questions, then we can help:

- Did the BJ run okay with NiMH cells?
- Are the BJ motor and ESC the same as came the factory?
- How many LiPo cells and how are they wired (4S1P, 6S2P)?
- What charger did you use to charge the LiPos?
- What plugs are you using between the LiPos and the ESC?
- How is the LVC set?

Try solder/resolder the flex shaft. About 3/4" of inch.
The side that slides into the collet.

jlr, there are two threads a few pages back addressing the loose/broken/sucky stock collet nut. I have used both the octura 5mm to 0.150 (short) collet as well a three piece one from Kintec racing (it's a tight fit, but really nice too). There are links to those products as well as helpful comments from the senior members that might help you out! One thing i learned quick was to make sure i didn't get any marine grease on the proximal tip of the flex shaft to help the collet grip. Hope that helps!
