4S2P Lipo

[motoxbob11]

This may have been talked about before but does anyone use a single 4S lipo in their Supervee? If so where do you mount it and does it work as far as center of gravity and such?

I would guess you would need to completely rerig the boat so you could put the 4s aft of the motor. I have thought about a similar rerig for my nimhs running one pack fwd and one pack aft of the motor with the servo rx & esc pushed outward. This would also help lower the c/g of the boat.

In my opinion I would like to change my motor mount so the engine doesnt stick up in the air so high. putting my lipo's on the side doesnt seem to be a plus or neg. but the motor rocking in the corners so high seems like it would emphasize the roll over factor.

I run 2 in parallel in the same mounting locations as the 2S packs, runs great and the bit of extra weight makes it more stable,,,,and at 4200Mah (8400 total ) equals reallllllly longgggggggg run times:D

The mods required for a single wold be large .

good idea I had not thought of lowering the motor

what kind of temps are you seeing with the extended run times? what is the rest of your setup IE: prop esc motor

Thanks

Like what Doby said just put 2 of them in and hook up parralel, or you can hook up just one Battery and not the other, and when you use up that one just plug in the other, Batteries never have to leave the boat

or......if you do one Batt at a time, you can have 2 fresh 8.4V fully charged throughout the day where as in Parralel the voltage of both Batts drop at the same time. although you'll have a longer run time, the speed decreases because the voltage decreases. you notice the boat is its fastest the first 20-30 sec. off the line at WOT.
P.S. "I dont know what Im talking about,"

There is not much difference in temps at all, I don't use the rudder cooling though, made my own pickup and the water just flows and flows. That's the key,,,coooooooooooling,,,,,ahhhhhhhhhh ,,,lots and lots of coooooooling.

[Avanti]

thanks for the info Doby I think I will be make a transome pick up soon

[motoxbob11]

I agree with Doby the hole in the rudder look very small for water intake. How did you make your pickup and what parts did you use?

[Avanti]

I'm going to make a through hull out of copper just like I use to do on the race boats I built. the tube will have a 90* bend in it and be cut on a bias where it comes through the bottom of the hull. then there will be a small vee dremeled out in front of it to direct the water. I'll be sure and take pics when I do it (should be within the next two weeks).

Would love to see the result. I just got my SV and I won't use it untill summer but I plan on using all the great advice from you members to get it set up correctly.

[Doby]

Here are some shots, just a piece of brass tubing held on by a small clamp,,,,water flies out of the hull over one foot staight out at speed. Moves water faster than SJFE moves from boat to boat .:D :D

Yea I did the same water pick up when I converted my SV to outoard last summer also

[motoxbob11]

Thanks for the pictures it looks very effective. I also got a kick out of the outboard conversion. How did that work out?
