Summit

[revo_rob_1984]

What would be a better power upgrade for my summit. . .a vtwin velinion setup or a kershaw designs twin 700H.O. brushed set up?

Definatly brushless, I hear the vtwin setup is nice

A buddy is running the mamba monster on his, it's rediculous fast. They fallowed it in the truck at 60mph and it pulled a wheelie and took off, they don't know how fast it will go. there wasn't enough road where they tested it.

I'm not looking for more speed. . .i'm looking for more efficient power and torque. . .i could care less if my summit does 30 but i want more torque

I just installed dual 775's in my emaxx using the kershaw motor mount. Tons of torque plus enough power to gear it way up w/o worrying about excessive heat. I dont know how they compare to the 700 H.O's but there is plenty of power to spare with these things at about half the cost of going brushless.https://www.rcnitrotalk.com/forum/attachment.php?attachmentid=10170&stc=1&d=1315523330

By design a bruhless will be more efficient than a brushed set-up. For more torque, look at motors with a lower kV rating.

What this guy said!

I use 35-45-55t motors in the crawlers/scalers I've had and it delivered the torque for sure but no speed really, I would stay brushed unless you pick up a lower kv rated sensored brushless setup.

I got the kershaw twin 700 H.O. kit

please post some pictures of the install
and if you could post a video of how it runs that would be great
i wanted to change mine out but would like to see how it runs before i do
thanks!

 

[revo_rob_1984]

absolutely, i'm gonna tear into it this weekend

 

[MudSlinger33]

I will try to post a video of my 775's, then you can compare the two. Too bad we can't just race.

 

[revo_rob_1984]

i'm gearing mine way down anywayz for more torque, its gonna be slower than stock but WAYYYYYYY torquer

 

[revo_rob_1984]

ok so i got my new system installed but now i need to figure out how to break the motors in, it says to use 3.6-4.8 volts of power for an hour under water, but how am i going to get that voltage. Dismantle an old Nimh pack and remove some cells (basicly making a 3 or 4 cell battery) just buy some cheap Dcell batteries and solder them together. Pleas help me i'm soo confused

****UPDATE******


The kershaw designs Twin revolver 700H.O. upgrade is an awesome upgrade for the summit, sooooooooo much torque, i had to upgrade to steel center shafts and cvds so i would quit twisting them. wheelies on demand and plenty of torque to climb just about anything with no cogging. . .i love it

That is definetly good to know My summit should be mailed out today and to me by next friday.. and I am already looking at good upgrades for it. I was trying to find that duel motor mount alone because I have 2 of the titan 775's so I dont need the extra motors, I dont think.. anyone know where to just get the mount alone???

click on products, scroll down and click on motor mounts, click on summit and its the first one on the top of the page

 

[mtaylortank]

did you ever figure out the break in on those motors and how are they going??? I was also wondering which you might think is better the titan 775's or the motor's kershaw puts in that kit the 700's I think..

i used 3 dcell batteries wired together and ran the motor under water for about 90 minutes, and i tried 2 775's my buddy has a summit too and i robbed his motor for like 5 minutes just to see how it ran and the 700's ran alot better as far as i'm concerned

 

[mtaylortank]

definetly good to know!! I was thinking of either going dual motor or go to the momba monster combo. (the one in the t-maxx,and E-revo)
