motor angle

[iceman]

when installing my motor in my rigger is there a prefered angle to put it on? planning on building my mount from 2 pieces if 1/8 lite ply with carbon fiber sandwiched between them. also is there a tubing that goes in the brass tube that goes into the strut? i plan on using a 3/16 flex drive. thanks for any help given.

come on guys

come on yall i need some input here! also going to run the fiegao 8s on 6s what esc do you suggest?

I'm guessing no more than 10 degrees. I install my motor as far up in the boat as I can. I have made quite a few mounts out of plywood. Keep the mtor as low as possible for center of gravity and angle of the stuffing tube. I also try to keep the stuffing tube as straight as possible. Usually I have a a very shallow bend in it.

An 8s on 6s? Are you sure? Walk with me.

6s in series is at least 22 volts. The Feigao 8s is 4761kv. So 4761kv x 22 volts is 104,742 rpm. Let's say you manage to get 85% of that to the propeller. You'll be turning 89000 rpm give or take. A tiny little Feigao will not be happy to hear this. The smallest prop you could put on that would be a 536. That will put you around 160 mph. That is assuming that a 536 will bite enough water to plane out a 6s boat. So it doesn't really matter what ESC you put in there. Use a cheap one since it's probably going burst into flames instantly anyway.

I would strongly suggest you try something different for a 6s boat. You need a bunch more rotor working for you.

A Neu 1527/1y with maybe a Swordfish ESC would be a great choice. The Neu are pricey but the quality is pretty solid.

I like the Castle Hydra240 for 6s but people have had problems with the Hydras on 6s. I haven't yet. Most of my ESC trouble is self enduced.

The Hydra ICE I'm extremely unhappy with. They have a long ways to go before I'll be sold on those.

Someone that knows the Leopords should have a good suggestion in that line too. Much more economical than Neu but I don't know about longevity. Probably comes down to how hard you want to pound on the motor. I've heard no complaints about the quality yet though.

Trying to help. Hope I wasn't to much a weeny.

Terry,

He talking a 6S or 8S Fiego motor. I'm assuming that he is going to run it 2S.

Uh, no he isn't.

also going to run the fiegao 8s on 6s what esc do you suggest?

[jstolz]

Uh, no he isn't.

OOpps,

Trying to do to many things!! Ignore my comment!

[iceman]

thanks for the info maybe i need to rethink the 6s thing.would 5s work or would i be better with 4s. im just a rookie trying to have some fun the amount of info on this site is awsome and if i stay around i might learn something! LOL

I think you probably want to start back at the beginning. Give us your hull dimensions and maybe a picture of it along with hardware and whatever else you already have. Then I'm sure some members recommend a good power setup - motor/esc/voltage/prop. We usually try to target somewhere around 30,000 rpm, so if you were going to run 4s (14.8v) you would want a motor around 2,000 kv. I personally don't run riggers but many others here do and will help you out.

No sweat Gary. Hang in there. Sometimes our efforts to bring someone up to speed comes off like we're a bunch a' know it alls or just seem like we're a'holes.

There is a ton of info on here. Rumrunner is full of data too. If you know what your looking for you can find it.

You might want to reverse design a setup. Decide how big and how fast you want to go first. Then consider if you want to try racing it. You don't have to but the option is always out there. Once you make up your mind on those things we can point you in the right direction.

A Feigao 8s motor is maxed out at 2s. You might get away with 3s with a boat that's light on it's feet boat. An 8s motor in a rigger around the 26" range will work on 2s.

To cut out a lot of trial and error you might even consider a JAE kit. Runs on 4s with a Aquacraft motor and ESC combo. 40 to 50 mph without too much tinkering. You could even go crazy and jump up to hotter motor combo in that boat later. With the AQ setup you can have fun and even race it if you're so inclined.

Building a 6s rigger is takes a litle extra thought and effort. Well, I think it does. Enough that I haven't built one..........yet. And I have more boats than brains.
