Rio EP Brushless *Soon*

[v-spec]

Well the Rio esc died the other day when I was testing props. So I stripped the hull today in preparation for brushless power.

I've still not finalized my set up power wise but I've been busy with other ideas. I'll post pics and info as I move along with this build. Here's a couple so far.

A few more pics. Mock up of SV27 hardware. Rudder bracket is a little big so I'm either going to modify it or find something else. The SV27 rudder blade is also about 1 inch longer than the Rio EP blade, not sure if I should go shorter or leave it this length since it's only a single rudder now...

was it possible to use the stock set up with like a 2900 3000 KV motor like the proboat widow maker 22?
Did you realy need to do that much work to it to get it brushless ready?

[westbeach]

that's some serious work you have done there. The CF looks good. Are you upgrading the current flex shaft to higher gauge? BTW what is the stock flex shaft size? Seems like an 1/8".

You could just drop a brushless right in. The only thing to worry about would be the water cooling jacket with the EP mount. If I used an L size 540 inrunner I could prob just stick the stock cooling coil on it but I was considering using an S size can and that would be to short to fit it.

I will run a stock SV27 flex shaft in it. The stock one looks to be .130 cable I'm not positive though.

I'm trying to figure out how I want to mount the motor right now. Forward like factory or in the rear with batteries up front. ? ? ?

Thanks for asking about the flexshaft I was about to order one for an SV27 I forgot I already have 2 of them though!

Cool so it's got good enough parts so you can just hook it up with a cheap brushless set up.. That's good ...you almost scared me away from getting this boat from the photos above ...I don't want to go that crazy if i get one.

I had a feeling I might scare some people off. I really considered not doing what I've done for that reason. I never build my models or big stuff really over the top. I like to keep things simple and neat. All my boats are very conservative and I worry about driving, set up and consistency.

But today I thought what the heck I might as well do something I normally would not. Nothing wrong with a little fun I hope!!

Nothing wrong with that !!
If i get one i will probably throw a cheap brushless system in it with a 3000KV motor and use the stock cooling but put a better coupler i hate thoase ones they used on it!

Good luck with your project hope it FLY'S for ya when all is done!!

Get one and do it! I wanted the Widowmaker motor with a Blackjack esc for this boat but I could not find the motor in stock so I started getting other ideas!

Nice work on that carbon. She should be rigid now. I wonder how well that tactic system will work surrounded by Carbon Fiber? Just curious because I bought 12 new Rx's for all my boats. Now I would like to add Carbon Fiber in a few. Please keep us updated.

Thanks

Sure thing. My 2.4 worked okay in my Titan 29 with carbon floor. This boat has about the same amount laid in it so we'll see!

I build my son a Delta 25 copy with a feigao 540 9L and x-power 100 on 2s lipo. I was trying to put together a 30mph boat that would be almost bullet proof. Ran it all day yesterday with no heat issues with a x442 prop. Its no saw about, 30 mph, but its fun and HOPEFULLY reliable. Every one always shoots for high rpm, this boat is only running about 20,000 rpm. I have a limited tool box, so I didnt have a temp gauge with me but the motor was barely noticeable as warm.

Just for the hell of it I'm going to give it a run on 3s, when my sons not looking.

My UL-1 has a 1500kv motor on 4s and it's RPM is low but I'm right at mid fourties right now and it's a great boat. I usually run for a timed 3 mins but yesterday I ended up with about 5 adults and at least 10 kids that were going crazy over the boat so I ran it about 5 mins straight and things were just a little on the high side of warm. Maybe felt like 105 or so on motor and esc and batteries were cold.

I agree with you both lower Kv ratings and a little more voltage keeps things cooler. Not as many amps.

V-Spec thanks for the info on the Carbon, I'll be waiting to hear from you Friday.
