I tried that one too withthe typhoon outrunner. Great prop, similar performance to the 642.

Hey forescott, hope you don't mind if I add to your thread a little. Just wanted to show what I got going on so far. Seems like we are both on the same page with the BJ and Outrunners. I need to get a eagle-tree asap, but once I get one I'll have some data. Here's the 3 motors I have for the BJ.
- Venom (KOS P1) 2000kv outrunner with bracket. I was really shocked the bracket was a direct mount to the BJ.
- CC 1800kv outrunner (same as forescott)
- Turnigy 500 1800kv outrunner (same as forescott)Comment

I'd hate to ask a dumb question but what is the difference between an inrunner vs outrunner?Comment

Be my guest Diesel! Wow the p-1 motor mount lines up with the BJ mount holes. I also have one of these on the way!

With an outrunner, the outer part of the can spins instead of the inside. Outrunners typically have more torque and use less amps than inrunners. Obviously if the outer part of the can is spinning, then they cannot use a water jacket. Most outrunners have some type of fan/blade setup built in to the end of the motor can to circulate air when the motor spins. Thus they are air cooled, but can be used with a water cooled motor mount to aid in the cooling as well.Comment

Can anyone recommend what timing to set on the ESC for the CC outruner, or any outruner for that mater?
Thanks!!Comment

Which esc? I use the 18 and 22 degree timing advance on the turnigy/seaking models. Most outrunners need high timing.Comment

Sorry, it's the turning 180A. I ran it today at the default setting which I think is like 15* and it ran like a bat out of hell!!Comment

What prop did you use?Comment
-
42x55. I'll add the video just in case you haven't seen it. I don't have a GPS but it looks way faster than stock. Still have not adjusted the strut from how it came out the box so the bounce is still there even with the batteries hanging 1/2 out the back of the tray.
I'm guessing this setup should put the B26J in to the 50's considering it's lighter, no?

I have a pair of 3000mah 5s packs on the way to run in paralell. Should see 50mph then.Comment

Went back to the typhoon 1800kv outrunner in the blackjack. The castle outrunner was a little too much for the 26-inch hull and was causing some big torque-roll issues. The smaller typhoon outrunner seems to be a perfect match with the turnigy 60A esc and 642 prop. Speed is around 40mph on 4s and the motor comes in at around 110 degrees after about 7-minutes run time.Comment

WOW great info man. 7m run time that's impressive. I am still waiting for the weather to break here so I can run my setup with the 2000kv venom/suppo outrunner. I bought a eagle tree so I can get some good data. Gonna try it with the stock esc. Hopefully it handles the motor ok.Comment

What drive hardware are you going to use in the BJ Scott? I'm working on my second hull and have thought about making it a twin as well.
I never called you about the Genesis because I bought a 4074 2200 for it. I'll make it a twin when the 2200 gets boring, lol!Comment
