New Hobby King Cat (Surge Crusher)

[FighterCat57]

that hull seems to need a rudder that has a build in shaft holder does it not?

Depends on the size of the rudder mount base... There is about 19mm of height available on the tail of the new cat hull.

The other option is to find a longer strut hanger that accepts the rudder and just replace it, making the existing hardware an "all in one".

It *looks* like the hardware will work.

I'll have one of the R2 hulls here this week if you want measurements.

Thats a good Idea with the ply. I just has another look it's cracked pretty bad from the motor mount back down both sides of the hull

I was looking at that hull as a replacement not sure if the surge crusher hardware would work on that hull. Idea's anyone?

You can use some light ply to reinforce the center section of the hull. That would be easier and cheaper than using composite fabrics. Also a bit stronger and quicker...

Possible candidate for the switch:

Just look for a cheep non-surge crusher hull and put everything in it!

[j.m.]

That probably needs reinforcement as well. Especially with the bigger motor...

If your going to buy the super surge crusher, i'll take the damaged one and try to fix er up!

[Graeme]

yeah it seems like I could fix it well see what supplies cost.
I could also paint the middle of the hull black or something.
or just buy the super surge crusher.

[j.m.]

Ouch....

So I guess now you need to take everything out and reinforce the hull when it arrives from HK.

That may be salvageable. As long as you don't mind gelcoat cracks, you can fix it.

Took the boat out for a few runs today came home and discovered the hull was badly cracked around the motor mount.

Awesome and thanks! That would be some good info to have! It is for the villain right?

I almost bought that little screamer outrunner that ose sells for a 47inch mono but i decided to go with a dual kb45 10xl's in a gearbox to one outdrive. I figured i don't have to change the prop for different speeds with the gearbox and i have more options if the hull ever breaks. I almost want to put the same set up in a big cat to see what happens!

I'm putting a pair of outrunners in the Villain (2s 450 heli motors), Das Boot and an EKOS. Das Boot is 2200Kv 1500w 4s (32" HOTR twin cat), EKOS is 1700Kv 1700w 4-6s. All are twins. I have a Little Screamer about to go in an Osprey.

I might just need to get my first outrunner! What is the most power you have put in into these motors?? I want to try to get at least 2kw at 6s.

Nice! I'll have to put an amp meter on some runs soon, I'm waiting on drives right now.

[Jacked1]

Careful, that is only a 475w motor. Why not go with an out runner? They are air cooled and more torque! I'm using two of these on another project: http://www.himodel.com/electric/1700...ype_H3650.html

Way cheaper too! I'm having really good luck with outrunners. They are very light and very powerful compared to their counterparts. I haven't had any heat issues with the motors being air cooled either.
