Just curious, why no lipo?
The Feigao 8 or 9s would work well with 7.2 volt nimh. kv x volts equals rpm. Shoot for 30-35k rpms.
For the Rio ep, you would only need a S size can. The larger motors will have too much physical mass for that hull and may hinder the handling. You could use an L size can, but it's unnecessary.
I already have money in nimh batteries and the charger I have is a great charger, but it's not for lipo's. The big reason is I just run boats by myself for fun and I don't need to worry about LVC and charging/storing my batteries a major deal. NIMH are just way easier and suit my application way better. Who knows I may switch sometime down the road, but for now I'm happy.

8s
You guys think this is ok?
On ebay type in seaking esc. The 60 amp is VERY affordable and waterproof/watercooled.

AHHH sweet! that does leave more options.
This is what i'm thinking for my RIO:

http://www.offshoreelectrics.com/pro...?prod=fei-540L
6L (4116kv)
On my batteries that i run i should reach between:
29,635rpm on my 7.2v nimh and about 34,574rpm with my 8.4v nimh. Sound ok?
I tried my novak 4300 and it stunk it reved way to much you would have to use a really small prop I think i tried a 38 or 35mm prop and it was slow because it reved so much you would need even way smaller of a prop...and also on NIMH packs the more KV the more strain and heat on all parts and battery packs.
Wow the shipping is 30 bucks on the esc!
and the motor you want pulls over 100amps, that will cook the esc
better to go low kv high volts, uses less amps
If you have the XVL already, I would use that and see how you like it before buying another esc and motor
the VXL motor makes awesome power!

Hey sweetz, did you say the titan 12t gets like 26000 rpm? When you tested that was that with lipo's or nimh?
Keep in mind its more than rpm..
these brushless motors put out way more power and torque than the brushed motors you are replacing
just because the rpms are lower does not mean they will be slower, you can prop them up and get alot more speed if that's what you are after.
25mph+ should be very easy in this hull with a different motor and esc change

I've been working on two other boats right now, but I still want to try one of my Team Orion Revolution 13x1 motors on 2s in this hull..
it could be to much rpm though, of about 37-39,000rpm, and around 230+ watts

Let me know how that goes. Curious to see the results. I just ordered an upgraded water jacket and an additional water pickup for my supervee. Pretty soon I'll put the ammo recommended upgrade motor into the supervee. Don't have the extra $$ to do it know since a new video game is coming out on tuesday need the cash for it. (Call Of Duty )
will do
one thing to try is use a small pointed file and ream out just a little on the water pickup in the stock rudder, that will give really good results with cooling..
My temps never get abouve 120* no mater what prop I use and two weeks ago with a CF45 my temps were only 90* on the motor and only 87* on the esc using the stock rudder pickup and stock water jaket..

FYI, there is an xpower 100amp esc watercooled in the swap shop right now for 50 bucks. would be perfect for this boat!!
