o yea..1 more thing
cat is 2" shorter than ekos make sure inerts are the same dimensions.
just to be safe.......
check the flex first may be ok...mite just have wrong prop for pics...
seen it done before to club member
again nice cat...good choice..saw this first but
was out of stock so ordered the ekos...love this boat
but now i hate the paint....off i go to to get some sandpaper

Well since it is a replica and since I'm the only one around with this hull paint scheme..I love my paint. those motors look to be better suited than the Venom motors..and your esc is probably better than ours. I have no problem running 4s lipo on my esc nor issues. Its says 2-6s lipo might want a low mah if you go more than 4s. I also got a couple of hair line cracks none are break thru hull so I just used marine hair line filler,and some of my epoxy glue on the left side front. put your mouth to it and suck..no homo.... if you suck in air the nyou have a break thru. I don't want to hit 66mph in this hull I see bad things happening. I'll be happy at 50-55 mph all day every day set up.

Thanks for the tips.
Let me ask a question. For those of you experiencing cracks in your boat. Have you thought about reinforcing the hull a little bit with an extra layer of epoxy resin. Or apply fiberglass matt where you are finding the cracks with the resin. Or maybe a layer of carbon fiber with resin in the problematic ares?

I was going to order these but the cooling jackets are out of stock.

I run a pair of these on the stock ESC's 3s/4s w/32mm props and get about 53mph out of it. The motors have 19 &25mm spaced mount holes and mount in the stock position.

Order a pair of Jeff's EKOS wire drives and Couplers. Best drive available IMO.

HTH- Good Luck!

I did order the wire drives and octura 1/8 couplers today. I may order a spare set of flex drives too. I understand the wire drives are good. But it sounds like it has to be a straight shot from the motor to the prop. if there is any bend in the wire drive it will cause problems. Am I correct or did I misunderstand this somewhere? Seems like the flex cables would be more forgiving where you have a slight bend.

I looked at those motors and read the reviews. They dont sound to bad for the price. They do look a lot like the venom ones tho and thats scary lol.
I know the new venom boats have out runners. And we have yet to get any feedback on how those work in these hulls.
But I know outrunners can make more torque than the inrunners. And the can be fan cooled like on the heils and other rc's. I have even read where people have been using out runners on boats and like them. One day I'd like to see what out runner would work well in this hull other than the venom ones.

The problem is the 19mm stock motor mount holes, limiting to 380 size motors with 19mm spacing.

I have a pair of 540 outrunners in another 32" hull, much like this one and love them, they sound awesome. 500-600 heli motors. (generic 32" cat thread)

If you're up to changing the motor mounts, I can recommend a few motors.

I might hit you up on that. But for now I havent even got the boat its on its way to me. It was in the UK then germany now in NY. So it wont be long lol. I plan on running it stock a couple times to see what its like. then change out the flex cables and try diffrent props. then motors. and im sure ill be fixing things that break. I hear the rudder setup is weak so I have that to watch.

Yeah, the rudder is not break away, so be cautious...

I was looking at battery packs and what some are posting they are using. I ordered packs and paid a pretty penny for them. but now looking at the specs of the packs others are using i wonder are mine too long. mine are 6.5in long or i think about 160mm. are the packs going to hit something up front in the hull being longer?

That hull/battery holder is different than the EKOS, so can't say...

ok. i am looking for some 4s to have on order. i was looking at the turnigy 4s 5l nanos. but im not sure. guess i should wait till the boat comes. should be thursday

Yeah, the height from the hull to the hatch is a limiting factor... only like 33mm + or - .

[JPriami]

thats good to know thanks

[VIKOS]

nope just epoxy when you find a crack thats all the way thru..most are just hair line and are ok..epoxy is great. On another note where did you find this boat I might buy one and upgrade a lil bit...good that both boats can swap parts on each other..I'm going to bump up prop size t o34mm next week..raced a thunder tiger OBL and tore it a new a$$hole today lol. Those v hulls are crap but they are quite though...lol KOs FTW!!!!
