Glad I could help you out Ryan. Man go for 6s and really see what the 1527 can do for you!!!

I plan on it in the future. I may have to upgrade the esc though. I've heard too much bad about the lv240 on 6s. I may try a Swordfish hv when steven gets them. This thing should see mid 60's on 6s I bet. I love how this hull eats up the chop.

AHHH! I've been to Mauii. I never wanted to go home. Not sure why I did... I could snorkel and surf endlessly. I've gotta settle for crappy east coast snowboarding. At least I've got tons of lakes when it is nice out..

:eek:Man you guys are crazy running in the ice water!!! No emergency rescue missions that's for sure!! In the winter here the water is in the upper 40's and i don't even hesitate to jump in after my boats ( even then it draws a crown) , but there ... Yeah right!!!! I would wait on the 6's unless you have a good recovery system ;) buts that's just coming from a so cal boy:cool2: GREAT VIDEO !!!!!

lol, thanks bustit, she lookms a bit different now huh? 58mph flat today. Running new cells tomorrow, still 5s, but higher c rate. I bet I'll hit 60!

Rumdog
03-03-2010, 04:17 PM
Not much better on top speed today. 58.5. I did pick up a LOT of punch out of the hole though. First rip and i flipped it right over on her lid! Wasn't expecting that! I dig the hard acceleration, just gotta be a little more careful now!

Well, I went with a x455 today. Woohoo! She's rock solid at 63.6 mph!! this cat rips wot hairpin turns! By far THE best handling cat I've ever seen! Still running 5s2p. Batts were a little warm, but other than that, temps were as usual. I wonder how much speed this hull is capable of.

Sweet, low 60s!
any new videos?

That's very impressive. I am putting a new power setup in my sprintcat soon, motor and esc. are on the way, just need to get some cells. I'm going from a 4s to a 6s setup. I hope to get up to the 60 range also.

Is the x455 the best prop you've tried?

Rumdog
03-24-2010, 06:41 PM
Yep, so far, the 455. I've only tried the octura's though. I may get a couple prather props. They have more pitch. So far, I've tried a x648, x450, x452 and the x455. I have a x457, but, not sure if it will be too much. Gonna try to talk the wife into filming this weekend. The lake are finally all thawed out, and I can really let her rip!

knpc, you going with a 1527?

...I wonder how much speed this hull is capable of.

I've had it in the 80s on 6S but it needed some add-ons to get there. That wasn't on glassy water either.

Yes, 1527/1Y, Hydra 240HV, 6s2p.
I had a 1521/1.5D on 4s2p, it ran a consistant 50mph. Motor is going in my df33 now.

what prop??

With the 1521/1.5d I tried a m645, x450, and P230. I got the best performance out of the x450, it ran 50mph and temps were good.. With the 1527 I'll start at the x450 and work my way up.

Rumdog / Knpc,

What is the weight of your sprint cats with batteries ready to run please.

Thanks

Rumdog

I never weighed mine. I'm not really ever too concerned with weight actually. I know a lot of guy's run similar setups and it has been proven to work, so i went with it. I does seem quite heavy for a 34" cat though. I think it helps it handle well at speed.

racerr73
03-25-2010, 09:01 PM
Thats cool, mine weighs a little over 14 pounds ready to run and i just felt that was a bit heavy for a 34" cat. Was just interested to know if i was in the ballpark weight wise with the other sprintcat 34inch owners.

Mine was 12lbs with the 4s setup, with 6s the packs are 1/2lb more each plus a bigger motor and esc so I should be just over 13lbs rtr.

Hi All
Running a Sc40 with a Neu 1527/1Y, X450 (and a few other slightly larger props), Turnigy Marine 180A and 2 Turnigy x 6S 5000 20C Packs in parallel.
The thing handles brilliantly and turns like its on rails but mainly because it is slow.
I would say around 40mph. Even if it were not set up properly with strut height etc I would have expected a badly handling boat that was still faster than this.

Now the packs are quite new and should be able to deliver around 200amps as they are in parallel. I am running 8AWG wire in the parallel adapter with deans ultra connectors.

1. What amp draw should I be expecting? (I want to run around 60mph or more)
I have an eagle tree 100a but dont want to blow it up by pushing too much through it

2. What C rating packs do you folks run? I am planning to purchase some 40c packs but cant get any at the moment for a decent price

p.s. Just adding that everything comes back cool/slightly warm. Nothing seems to be working too hard, not even the packs.
(now I wonder if I am getting 100% throttle from my M8 with spectrum module, must check throttle trim)

Cheers

Get some proper plugs, ie Gold Bullets, Deans are good for 50amps max..

Strut should be 1/2" above the sponsons. Run a x455 or x457 for FAST runs! Definately need bullets!!
