Project OverKill (hehe)
 

Hey Rc-Monster Users,
Heres my next/ First Brushless Project.
Quick Specs,
XTM Rage
1/18 4wd,
(fun part)
Mamba Max ESC
3s 2000 Mah Li-po
5000 Kv Trinity Brushless Motor
Ya, Over kill or what? Let me know what you guys think. :mdr:

what size can is the Trinity Motor, you dont need a MM ESC in an 1/18 scale....I have a RC18 with a Mamba 25, Hyperion yc-22(5000kv) and a FP EVO25 3s1500 pack and its all the power you would need

Which Trinity Brushless is it?

iam getting it 25 shipped from a member on here
yes i know the mm is more than enough power. thats the point, "Project OverKill" plus when i build my E-Revo (some day) i can use it

That motor is the motor that is used in the Trinity NOW which is made by Castle Creations

Correct ,but its made by CC, Hmm i didn't know that, thanks. is it a good motor?

That is a feigao motor. Looks to be a 180l size can. The cc small motors are 180s sized, IIRC. But they are all feigaos.

Hmm, iam so glad to have Smart RC People. because i though 5000 Kv would be a good balance between Acc.-Speed

Its a 280XL...

That motor is a bit small for the Rage IMO. It's barely bigger (+5mm longer) than a Mamba motor and those are notoriously bad for use in a vehicle that size. Even though it's cheap, you're probably going to have heat issues with it in that vehicle, especially on 3S. I'd suggest a different motor if you want it to actually live up to the "Overkill" terminology you're using for the truck.

Some motors that come to mind...
Neu 1105/2Y
Neu 1107/1.5Y
Permax Multiplex BL480/3D
Medusa 28-40-3400

Also, a MM is not needed for a truck that size...a Sidewinder is much more affordable and will work very well on whatever motor you choose. You also aren't going to find any 3S 2000mAh battery packs that will fit in the battery tray of the Rage. About the biggest you can probably sneak in there is a 3S 1600mAh Flightpower EVOLITE V2 pack.

where do they sell the 1100 series Neus......if you have a link that would be great, I thought the Mambas ran too hot, I have had pretty ggod luck with the Hyperions they seem to have more torque than the CC motors

Here's a couple I remember off the top of my head:

thanx for the link it looks like the 1105/2y would be a good direct replacement for my Hyperion have you tried any of the 1100 series Neus?

I have not used any of them myself, but rschoi_75 has. I run a Permax BL480/3D in my Mini Quake...it's more then enough power for me. It's 30 x 50mm and ~4200kv.

Nice Quake, yeah, iam still thinking about the motor now,i might be getting a MM for cheap, so thats why i was gonna use it.

you can get a mamba micro pro or sidewinder for $75 to give you an idea for a reference

ya i know, i looked it up last night, thats for the info tho, is there any diffrance between the mamba micro, and the sw micro (i don't think those are the "proper" names but they work)

The Trinity motor is manufactured by CC, The 280 sized motor features a long rotor for added torque, and 3 zero loss connectors that accept power from the ESC.
That is what Xtreme RC/RC411 said when they did the review on the NOW.

hmm, so what iam asking is a mm, 5000 kv motor and 3 on a 4wd 1/18 car, gonna be over kill?

The MM and 3S, yes, the Trinity motor, not so much since you'll have to gear it down to account for it's smaller size and lack of torque. I still think you need to consider what batteries will actually fit in the tray on the Rage. I think you may be surprised just how limited few will fit without a lot of mods.

It ran with ease on the Trinity now on 3s. Got a little hot after a hrd run but overall it impressed me.

With it being 20mm diameter, it's smaller than most motors folks are running in the Vendetta, Mini Quake and Rages these days. 28mm diameter is more the norm for big power.

Also, the difference is that the Now is geared to run 40mph on 3S with that 5000kv motor. I've got my Mini Quake doing about 38mph on 2S in my Mini Quake with temps under 110F for the motor. Running 3S on the setup I have would be more what I would consider "overkill".

Its not going to be outstading but it always managed to get the Now on its back quite easily.

IMO your not getting overkill in an 18th scale untill you get the vehicle going over 60 mph, for those of you who have never seen the small 1/18th scale go that fast you are missing something....

that is unrealistic

overkill and unrealistic are 2 different things. overkill you can actually drive.

unrealistic is just impossible!

1/18 going 60........... i couldnt even imagine!

Not sure about 1/18th scale MT but a 1/18th scale car it has been done

failed to hit 65mph but made 60mph
http://www.youtube.com/watch?v=dZMvc1HyGSo

This one made 78mph
http://www.youtube.com/watch?v=MP9IIaG3mak

This one 82mph

:gasp:

thats what they said, then Tony Phalen went 79mph at wfrccc 06'

With all due respect.. I've got quite a few 1/18 scale rc's now (8 of them) all of which are running on 3s or 4s. Attempts at "overkill" have often lead me to overheat instead. On 4s, Neu and Permax motors run cooler than any of my other motors and CC Mamba Micro Pro handles 4s just fine. Speeds at 4s running 4200kv motors takes a steady trigger finger and lots of wide open space. On 3s, Hyperion Y-22 motors(long can) are probably the best overall performance/cost option as they give you enough torque to gear up for speed and get relatively warm but not hot. I'm running a Quark Pro-Car and Dynamite Tazer speed controls without problems at all on 3s. If you can buy a MM for cheap, I'd keep it and use it for a larger application as it is simply not needed here. The Trinity truck isn't the heaviest 1/18 car out there, but it does need any of the above-mentioned set-ups to stay happy. Hyperion short-can motors(5000kv and up), Aon 6000kv, Wraith 7000kv motors all just made heat when I tried to push them in my Trinity truck.

As for batteries, I buy from United Hobbies. Cheap and available in different sizes and discharge rates to suit most applications.

It's nice to experiment with what-ifs, but at the end of it all, I think everyone wants a car they can simply charge up, drop on the ground and enjoy time and time again. Hope this helps.

did you ever try the Hyperion Y-22 long can in a RC18, I never thought of trying that, didnt know if it would fit or was that in the 1/18th scale MT, I tried the Wraith motor and thought it was the worst of any motor I have tried

im not saying it isnt possible because ive seen videos. im saying it is unrealistic to actually bash with one of those cars.

all you are doing is speed runs in the street/parking lots, but since the car is smaller it gives the apperance that it is actuall faster than it really is

my latest thought is that I will upgrade my Rc18, here is a list

ESC Mamba Micro Pro
Battery FP 25 evo 4s 1500
Hyperion y-22 4400 long can or Neu 1105/2y

I am thinking about the diffs they are the weak point in the RC18s

It's a feigao motor. I already went through one of them after the rotor decided to grenade on me for no apparent reason (used it within spec) and had to send it in to Trinity. It also has the classic "windings coming out of the can" in the typical feigao colors. The front also has the little bearing nub, whereas the CC motors are flat on the front endbell.

The ESC is made by Castle Creations, but not the motor.

On a side note, the Trinity motor in the NOW SUCKS. As I already said before, the rotor went on me from normal usage (slipper set so that it slipped about a half a foot, no drivetrain binding, stock gearing from the factory, proper gear mesh, etc.). The replacement motor I got runs just as hot as the first one (up to 180F after about 5 minutes with the stock pinion). I ordered a 4200kv 20x45mm for the NOW with fins on the can from hobby city. I may lose some speed, but so be it. As long as it runs cooler. The thing was a little too fast to use anyways off road.

for the diffs just use mip super diffs, delrin gears, 3 shims on the diff, and one shim on the gear coming off the shaft (i used a washer that goes behind the wheel pin) when u drive it slow its fells really tight but once you get up to speed it opens up and is pefect. i have not strpied a diff yet.

here is my setup

mm esc
8000 kv mamba motor
2 x 2cell 900mah 12c for a total of 1800mah 24c

That's still only a 12c battery. The C rating doesn't change if you parallel the batteries or series them. So you actually have a 12c 1800mah pack, not a 24c. Even at 12c, the 1800mah pack still pumps out about 21 amps continuous, so not like it's lacking.:mdr:

[/end nitpick]

I have the MIP super diffs but only the stock plastic gears...do you have a link for the delrin gears?

you can only get the delrin gears with the whole diff. i had gotten the diff and then sold the out drives on it.

you can find it at thetoyz.com


and thanks for letting me know that its still a 12c. me and my boss could not figure it out if it doubled the c rating. but it does put out a lot more power then my friends 2cell 1330mah 13c battery.

FYI Hyperion long can Y-22 series motors will fit in the RC18.

In my Mini Quake I run :

Thunder Power 3S 1320 MaH Battery
Mamba 25 ESC
RCer Warp4 2 Turn BL Motor (6 pole - 3880 kv)

All I can say is WOW. It is stupidly fast, I can rarely get it up to full speed, it usually flips before it reaches it. But great for bashing around, and I have yet to break ANY driveline parts with probably 35+ runs on it.

I have a Neu 1107/1.5D 8500kv motor in my vendetta and on 2s it's a beast. I'm trying to get a medusa motor to run on 4s. My Quark 33 thermalled all the time and my suppo (super simple) 40a got burning hot with the Neu. I got a 1/10th sidewinder and that still gets fairly warm on the heatsink. I must be pulling a whole lot of amps. I'm getting a mamba max now, and I'll be able to use it in my revo too. I have an Apogee 1500mah and a Fligtpower 1600mah 2s pack. I haven't done enough testing to compare the packs.

If you are going for overkill, get a Neu 1110/2.5D and run it on 4s.

Here is a vid with my vendetta with the apogee. http://www.youtube.com/watch?v=S32YX7e01cE
