Needing answers on 1st Build, ML Boatworks GSX 380-V2

What motor, esc, and batts (# of cells and mAh) are you using?

CG on this hull is critical. Answer the above and I?ll answer your questions based on your hardware and electrical compnts.

Good morning jingalls007,

Thank you for your assistance. I am using a Leopard 5692-1340KV Brushless motor. The ESC is a ZTW Seal 200 Bec 6V/8A. I will be using two Turnigy 5000mAh 75C 6S batteries. Is this all the info you need? Also, am I on track as far as the balancing process?

Thanks again,

Perry

Your CG will need to be exact with your heavy setup. I set mine up nearly identical to yours but with a SF 240 and I burnt up my controller on the first run. My prop was too big (abc 2016), and my cg was too far forward on a heavy boat. My boat submarined for 10 ft then she blew up.

IMO, the boat isn’t designed for that capacity. Mike made some changes on v2 to allow for larger packs, but I believe he also used a 300a controller to handle the leopard motor you’re using.

Mount your motor as far back as you can get it. CG will be 1” to 1.5” behind the leading edge of the sponsons ride pad.

Here’s a few pics of my setup. The changes I’d make to mine are moving the motor back farther, 300a controller, and using <10,000mah.

Good evening Gentlemen,

I am back at it and still somewhat lost. It's been awhile. Should I mount the Rudder on the Port side or Starboard side?? Also, what do any of you use to reinforce the area of the Sponson where the Turn-Fin is mounted, and across the Transom to support the Rudder and Strut??? The decision on this material is my current holdup.

Thank you,

Perry Bell

I?ve used aluminum plate drilled and tapped for the turnfin and also plywood with blind nuts.
