No Stick,
If you run too wet, you will pull more, so try some different setups.......add positive trim tab. If you're running a 45 size prop, you shouldn't have a heat prob with the packs, or motor for that fact. Of course, cheap packs will get eaten alive with this boat.

I do know the MRC series before the 977 had bad probs charging the lipos, but OC has had excellent results with his 977. I also use this too, but haven't had my helis in the air yet this yr.

It might be wise to hold off on A123s until Wazool can get some test runs in. I haven't heard of any others using this in the SV setup.

Ice,
You really don't have to run NiMh cells through a discharger. In fact, it is heavily recommended not to, especially with a light bar. When first forming new packs and maybe periodically/seasonally to check the status of the packs; if you're charger can discharge too.

A good rule for when to bring the boat back in from hull smackin' is:
1. Never run the packs all the way down.....it'll ruin them (heat).
2. I do a few vic laps when the punch starts to fade. If you're not getting a decent rooster, bring her in. It's boring.
