Slash guy looking for some direction
 

I got a Slash and want to go BL with it. I already have 2 2s 5000mah packs and would like to get a 3s pack too.

With that being said, what would be a good motor/ESC combo to run in it to achieve a good 45-50mph if desired and still be cool and efficient?

I was looking into the MM and a 5700 motor but from the reading I have done I hear it sounds like there could be some heat issues with it possibly.

Also what would be a good gearing to run on this that will work with 2s and 3s and still keep me within my parameters?

Thanks guys!

The MM will be a great esc for you! As for the motor choice try a Medusa 36-50-3300, it's available with a 1/8" shaft so you can keep your stock gearing setup. The Medusas are very good motors and will run cool. 3300kv should get you 40 on 2s and if you bump it up to 3s it would be a rocket!

as above

Thanks guys. I knew I could count on some good info here!!

How does this Medusa compare to a Castle or a Velineon motor??

The medusa will run way cooler than either and be able to pull higher gearing than either without heating up as much. The Castle 36 mm motors have small rotors as does the velineon. A MM/Medusa combo will cost a bit more but will outlast either by far!

Thanks for the reply. So what gearing would you recommend? Something I am able to run 2s or 3s in without changing gearing.

76/25 will get you about 37-38 on 2s and about 56 on 3s. Thats very fast for a slash! I would try 83/25 esspecially if your gonna run 3s alot. BrianG's calculator is a valuable tool!

Any other place to buy this motor other than Impakt? The 3300 is out of stock I see there.

Also will the motor bolt right up with no mods?

Thanks

Mike sells them here! As long as you get the 3mm shaft version it will bolt right up. If Mike doesn't have them in stock send him an e-mail. As a last resort you can order right from Medusa but try supporting Mike first! He will give you a good price on it and even if it's a dollar or two more your helping support this forum!

Excellent! Thanks

http://www.rc-monster.com/proddetail...usa3650&cat=20 Appears that he has them in stock! 36-50-3300 pick the 3300kv 1/8" shaft in the drop down menu

Yes just checked that out. What bullet connectors size should I get? I know I ran the 6.5mm on my E Revo. I was thinking 4.5 or the 5.5. 6.5mm would probably be a little overkill. Would be ran in conjunction with the MM.

4mm is what comes on the MM controllers

So I will just need the females for the motor then.

correct!

Thanks for your help tonight! I was undecided on what motor to get up until this point. I know I want something good. I had a Tekno Neu 1.5d in my E Revo with a MM and a cooling fan. I would still always thermal the MM. I do not want any issues with heat or efficiency with the slash. What a nice upgrade this will be from the stock setup......

Just so you have an idea of what your getting.....I run a 4800kv version of that motor in a CRT.5. That's a bit heavier than a slash and the 4wd puts more load on the motor, I even run slash tires on it! I have it geared for about 38 and even on an 90* day I haven't gotten motor temps over 130* I had a vxl rustler vith the vileneon motor geared for about 40 on 2s and I couldn't touch the motor after a run!

You know of any videos of a slash with the Medusa and 2s or 3s??

Wow very impressive!

I don't know of any videos off hand. Don't worry about the help...That's what we are all here for!

I know. I am a owner/administrator on another R/C forum, I know how it goes. Nice to run into good, helpful, knowledgeable people on other forums too! :smile:

Skellyo is running a Medusa in a slash but he went crazy! He's running a 60mm 2000kv version on 4s I beleive! He has a thread "slightly overpowered slashes", I think that's the title, not sure if he has any video. The setup he's running can and has powered an E-REVO!!!

little piece of advice, get a revo 40 tooth spur and buy a mod1 from mike and loose the gear cover the stock 48 pitch stuff wont last long with brushless.

Never had a problem with mine! As long as the mesh is set right and you keep the cover in place they should hold up for awhile. Going to Mod1 gearing greatly limits your available gearing!

how is that, i can gear mine anywhere from 35 to 65 with mod1 gearing..... 3s lipo 2700kv motor, you can gear down to 12/40 with mod1.... but then agian im using slightly smaller tires...and a lower kv motor

enlighten me as to where you can find a 65t Mod1 gear that will fit the slipper! A Mod.8 maybe. Not to mention that there is limited room between the input shaft of the transmission and where the motor shaft is. A 65t mod.8 gear is pretty large and would take up almost all that space.

My advice is to stick with what he has, if he has trouble with that he can change to a different setup. I like the age old saying of if it ain't broke, don't fix it! I upgrade as I break things.

if he gets the 3300 medusa with 5mm shaft he can run the mod1 gearing and gear from 35 and up

35mph* to 65mph*

well our tracks have lots of fine sand and tiny slate rock chips that reak havoc on gears weather they have a cover or not... ive seen a ton of stripped 48 pitch gears and most have upgraded to atleast 32 pitch with jato spurs if not the revo spur and mod1 im running, the mod1 gearing will NEVER gobad its eat and spit out rocks and sand all day no problems which is what we need around here...

I want it to be a easy install and bolt right up. I am going to get the 1/8th shaft and just run stock gears for it. Thanks all

Hmmm, I have been looking and was wondering if the 4800 Medusa would better suit me than the 3300kv. What do you guys think?

36-50-3300 Vs. 36-50-4800

What one would better suit me? Using the MM esc and 2s and 3s packs. Would like to achieve 50mph once in a while for some speed runs. Wheelies would be cool too. This would just be for a bash truck not a racer. Thanks

I would opt for the 3300. Would be great on 3s and allow gearing up for speed runs, and running on 2s should give decent speed and runtime. However, you might want to check how much motor adjustment you have to see if you have the gearing options you want.

I suggested the 3300 because it is very close to the vxl at 3500kv. The Medusa will be a touch slower but run way cooler no matter what gearing you run. I know 76/25 will fit as I ran that on my vxl rusty. There is plenty of adjustment available with the stock tranny

Awesome. I will be pulling the trigger on this motor and also a MMM for the ESC in the next two weeks. For the couple dollars more I am going to opt for the MMM over the MM.

He will be able to gear the Medusa a lot higher than the VXL, so speed won't be an issue and the Medusa has a lot more torque to get up to speed.

Well I just ordered the Medusa 36-50-3300 1/8th shaft from Mike. Hopefully he will soon have the end covers available for it so I don't have to worry about dirt and stuff getting in it.

Mikes cover's are really nice, but if you are in a hurry you can use heat reflective aluminum tape over the holes. That's what I have on both of my Medusa's and it shows very little wear after months of use.

didn't want to start a new post so. well i'm going camping this weekend and i just got my slash this week... what replacement parts should i bring with it. basically what have people broken on theirs
thanks
