32" hotr 90+mph

How about mike? He is kicking a$$ with them leo's, good for him.

Yes I told him he might as well follow your lead and go hv. Im worried he may burn up some caps running 7 s on the t180's .Maybe not. The fets can handle it but who knows about the rest of the esc?

I cant wait to see you get your hands on a 40 inch hull and twins .Those Leos are really shaking things up here on ose.

Im not lauging coz I know you can do it! I will be nice to see some 100 mile an hour cats on ose

About 125mph!! lol

Ben, I would make sure you can hold it at the stub first. Also has to be very true...perfectly drilled and find the sweet spot before it locks down...you can mark (stub and wire) them and then solder if that is what you are using.

I have one of your wires here to try first.

If you have the spacing correct at the strut a wire will actually push its way clear of the bend and lessen the resistance. That is why I use one bend closer to the motor. Also, are you running a thrust bearing at the coupler?

so howard whats next?

My corvette has all the bolt ons and is very fast i got to 183 and it was still pulling.

Back to drive shafts if want to get technical about it. It comes down to torque and hp. The longer the drive shaft the more torque will be lost. As the load increases the clearance between the shaft and the tubing will change. If your shaft has a slightly tight fit it will only get tighter as the load increases. When there is a bend in a shaft it will also cause some power difference. There is more resistance at the bend. I think its good to talk about things like this and let guys look at things from a different direction.

Has anyone run a 1527 1.5D on 10s? But mike. My motor mount is built and shipped. I will be setting up the new 32 and was wondering what S to go with.

I'm sure it can but you have to keep an eye on them. One reason I still like teflon in some wire set ups.

Yes, the slighter the bend the longer it will last but would be good for some time.

Cool. Think I'll try it. 10s 1520/1600 078 wire.

pretty sure those are stock numbers on a C6 actually and a z06 is like 500hp.

Nope. Depends on the dyno, but they usually come in around 330 whp on ours. The Z06 would be over 400 whp though. Big difference between crankchaft hp and wheel hp! Manual vs auto makes a slight difference too, as does STD vs SAE HP.

Your right about a car my 07 corvette has 400hp at the wheels and maybe 480 at the motor, lighter is better. Its much different when using a flex shaft, there are bends and flexing to think about. Take a power drill and put a flex shaft extension and try to break a small bolt loose but now go from 10" to 20". The longer the shaft the more power it will take. With something that has flex its always better to go bigger and its much different then a car. I wish we had a dyno to check small motors. I work with power tools all day so i know what happens with extending a shaft. Maybe its different but i don't think so.

you can make a dyno using another motor

Jeff, you think the wire could handle that kind of bend and rpm? I've spun one up to 45k rpm, but not any higher. They last quite a while, but eventually every one I've used breaks right in the middle of the bend.



Back to the motor; Howard, any thoughts on using a 1520/1600kv? It's stamped right on it... 60,000RPM.

I have one here, I'm getting ready to mount in a stock Genesis hull and see what happens on 10s.

If I remember corectly, Castle recommended not more than 40K in marine applications while they had this motor for sale.

[FighterCat57]

A flex is a noodle and will only try and wind up so it is always making lots of contact with the stuffing tube...which creates resistance. Wire does not do this.
