Selecting outrunner for crt .5
 

I am trying to pick the right outrunner if I decide to go with an outrunner on my crt .5. I am wanting to go with 3s. Here is the outrunner I think should work - http://www.hobbycity.com/hobbycity/s...idproduct=7073

I'm also considering this one - http://www.hobbycity.com/hobbycity/s..._1250Kv_/_630w

I will need to find a 4mm drive cup or an adapter if I use one of these motors.

Any objections/suggestions?

I think that would be a better motor. My buddy runs the 770KV version on 4s in his crt.5. But his is direct drive. Im assuming thats what your going to run is a direct drive deal?

Yes, I am running direct drive. I want the 1250kv motor over the 1000kv because I will be running 3s and not 4s. I am pretty much ruling out the 1400kv motor now. The other guy who did the outrunner .5 used that 1000kv motor on 4s. The 1250 is higher quality and maybe a little smaller.

this is the one i will be running.. its the 770 kv..http://www.hobbycity.com/hobbycity/s...v__EQ:_2826/12 :mdr::mdr:

thats just to much motor

What size tires are you running? 3.5's or 4in tires? Either way, thats 35-40mph. With your other motor choices it will run hot. You can go for it if you want. But id reccomend you get a 1000KV motor, or run 770 on 4s

I think I'm missing something... I thought that was BOR's CRT.5 in the 2nd to last post.

Its his. I sold it to him. But were both building it up

=)

The only thing I see wrong is that you have the computer on the wrong forum! LOL :lol:

Very nice, clean looking setup!

Will the diffs take the abuse?

umm idk if they will hold up threw the abuse... hopefully!!

and yeah that used to be BOR's crt.5 but then he sold it to me.. so now were both just kind of building it up.. :yes::yes:

Ahh okay.

Hahahaha, tell Dylan that:na:

Lets hope so! I dont see any problems with the drive line, maybe dog bones depending on how he jumps it. But it should be fine:mdr:

:smile:
So yea, its a work in progress. Now he just needs a sidewinder esc, CC Bec, 4s lipo, and a front drive shaft and its done

Nice. What length shaft do you need? I've got various ones laying around I'd e happy to send to you.

Let me get back to you on that one:mdr: I will figure it out :smile:

Thanks!!

I am currently running the 3.5" tires. Do you really think this will run too hot on 3s?

Ok, shoot me a pm when you figure it out.
