80+ mph 32" rivercat

There ya go Travis, I knew you'd get that 80 mph. Now let's see 90 mph!

I thought it was gonna do a little better with the Prather prop. It's thin as can be and it still prop walks. The m645 don't prop walk. I dunno. What prop should I try next? I know if I get a match 7s setup in the spc batts it's gonna pick up 1-2mph but I'm not sure on what prop to try next.

Went back just now. Ran on 7s. Hoped to pick up 8 to 10 mph but it didn't. Still a gain tho! Surpassed my goal...wooohooo! Video shortly

Btw, esc temp was 110f and motor was 118f. That was after making several hard passes and running around the lake for a bit. When I ran it more it didn't really climb higher. I did not revert back to the stock cooling block like I wanted to. Before the block I made the temps were 109 - 110f with less prop. The motor temps were about even with the esc temps. Now esc temps are staying lower. I guess the block helps. Doesn't hurt that's for sure.

Update:
Had intentions of trying it on 7s. I forgot my Y adaptor so I'm topping my packs off. I did a little back to back battery testing.

Test 1. Prather 230 prop. Strut unchanged from 70.0mph run. Venom 5000 50c packs. Well broken in. These packs balance perfectly every time. Result:



Test 2. Spc 6500 65c same everything as above.

ESC looks good in there Travis. You're becoming a CF king. Hehe

[kfxguy]

Travis, you really want to get slick? Cut some new hatches up forward over the sponsons to slide your 4s packs in, like the ones on this Hydro.[ATTACH=CONFIG]118131[/ATTACH]

That's pretty slick...and I could do it but I got it working now. I think if I put batteries that far up front, she'd submarine when I let off lol. It's also full of foam up there too so that would be a mess! I'd rather just build another boat

I upgraded the cooling on the esc also, figured it could use it. (Most of you saw this in my other thread so sorry for the repeat. Just wanted to document what I've been doing)

Travis, to run 7S or 8S in the T180v2 you have to turn off the LVC and add capbanks an external bec wouldnt be a bad idea either. Another nice build bro... DJ

PS: set lipo to auto detect

Update: this worked like a champ. Thanks! Now I can run it on 7s. I have a problem tho. A 4s pack will not fit no matter what.

I ended up using a loose matching cell and added it in. I put it in against the wall to the outside left of the boat, velcroed in place. Then the 3s pack gets strapped in essentially sandwiching it in there. I'm tempted to go run it tomorrow. Bad thing is I just ordered a $85 4s pack I can't use. I even cut the side rail thinner. Nope.

I wanna try something different so I figured I'd order some stainless ones. I won't be getting the 225 Prather tho. Ose is out of stock so I ordered them from kintec, he refunded me for the 225 a day later. Guess he didn't have them. I just bought an etti 7s 150 amp pro race controller and three more batteries....2 3s and one 4s pack. All 6500mah 65c. They are spc packs, I seem to be having good luck with them. They are constructed well and have noticeably more power than my venom. I already have a set in my possession that belong to my buddy and I've compared them to venom in my buggy. I expect just the batteries to pick up a mph or so. I'm gonna sand the bottom bur I'm unsure what grit...600?

600 or 800 will be good....

Cool, I like the stainless better myself. They are harder to work with but the end result is better and they are stronger..

If you want to go fast try the abc line of props. Maybe a 1816 for starters.

And get Chris(Dasboata) to 'do one up' for ya
