Feigao 540XL in UL-1 !

[Brushless55]

Just wondering if anyone has tried a Feigao XL in a UL-1?

I have a 6XL in my Erevo and that truck is nuts on 4s and outright stupid on 6s!

that motor keeps looking at me like it want's to go into the UL-1 !

Not sure if I should try it or not?

6xl is too hot using 4s lipo in the UL1. Perfect if using 3s lipo (3s2p)

[Brushless55]

I was thinking of that..
I have two 3s I could run parallel, the same way I run my truck on the track..

Awsome. A Hydra 120 should work easily with that combo

[Brushless55]

Great to know..
What about the stock esc, would it work?

[detox]

I doubt it.

Anyone's thought's on a 540XL using 4s and a 120 amp ESC in the UL-1?

[Rumdog]

Can't beleive no one's doing this yet

[Brushless55]

That's why I'ma askin..

[rcboatfan]

just try it man!!!!

[Brushless55]

just try it man!!!!

First I want to work on my Mean Machine...
single SV motor setup, and then I might try a twin!

Im sure it will work but you probably need to step down to a 40mm or under prop maybe even a switch from x6xx series to x4xx series if a x6xx series is what you currently run.I think you could run 6s lipo on a 9xl with like a x432 thru 1732 series prop. All 32mm ,but youll probably cavitate. That's over 6oooo rpm at almost 3 hp.The motor will likely get warm too.A SAW set up?

[Brushless55]

3hp only if the motor is pulling the amps....
32mm on this hull possibly not a good idea..
9XL on 6s is about the same as a 6XL on 4s for rpm
an 8XL would be a great choice on 4s or even a 7XL on 4s would be awesome to!

[Xfactor]

Oh it can pull 100 amps but it will get warm

[Rumdog]

9xl on 6s is waaay too hot! No good!

I'm in the process of this right now. So far motor is installed (7xl) and esc is soldered and ready to go (turnigy aquastar 120amp). I should be able to run this weekend. I've been out of town last few days and didn't have a chance to run it, but it is 97% complete. I also have a upgraded flexshaft and will be running a grim 40x57/3 and also try a x440/3. I'm going to try is on 2 2s1p's to start and I am going to order 2 4s batts and run them in parallel. I have to place a order for the 4s's though. I have holes cut out to try to splay the batteries through the sponsons and I also have a airdam ready to install if need be. I will play with different lipo configurations to see what works best. I am also going to pick up a garmin foretrex 301 gps on sunday. I will post video as soon as I can, prob monday or tuesday if weather works with me.

I agree, I think that could cause issues, and trying to fit 6s in a UL-1

Oh man, that sucker is going to fly!

I have a coupler customers running 540 7xl's and hydra 240's. So far they are happy. No gps speeds from them.

[Brushless55]

maybe just for fun, I should try the 6XL I have lying around...
not sure what prop to try with it though?

[Steven Vaccaro]

I would start with a Octura x438. Hopefully its large enough to lift the transom. If not stop right away and go a bit larger.

[Diesel6401]

Yea I can't wait to try it out.

Hey thanks Steven!

9XL on 6S -- Will need more than 120 amp esc, I run this combo in my Sv27, and twin in a H&M Maritimo, need at leat 180 amp esc, and start a little smaller on the props. should be OK.

If you are in doubt, go to 10XL on 6S.

Cheers...Tim

no one is looking to run a 9XL on 6s in this hull...
I'm thinking of trying a 6XL on 4s with a 200A esc

whoa...

[Brushless55]

It could be a good run, or it could go wrong

[Diesel6401]

I had a issue with routing the wires, but I think I figured it out. This is just a mock up and I still have a few more things to do, but it looks promising.

[Brushless55]

It's looking good!
