Suitable kv's for a Vendetta on 2S ?
 

Can anyone give a hint a on a suitable kv range for a rather stock (I do have CVDs) Vendetta ?
I am not looking for crazy speeds, abit faster than stock would be nice though. I will use it for road, carpark, bashing playtime and no track drivning.

I am thinking about 5400 (Mamba/CC) but what about 6800 what will be the differnce in performance ?

Go with a Hyperion YC22S-5000 or YC22S-6000 with a Mamba or Quark esc. You can also try something crazy like a Mega ACn16/15/1 (9200Kv) or a Neu 1105/2D (9700Kv), 1107/1.5D (8500Kv) or 1110/1D (9200Kv). I have the YC22S-5000 in my MLST now and it's a blast to drive.

I am thinking of trying the medusa 28-32-4200V2. They seem to be good (powerful) motors. You can gear up for higher top speeds, and use the lower gear for long runtimes. With the castle or quark esc.

i have the hyperion with the tekin mini rage esc - i had a mm25 but found it cogged a bit with the hyperion - this is fixed probably in 1.17.

i'd try the new castle micro pro...

You might only be able to fit a 16 or 17T pinion if you go with the 28mm diameter motors, but it should be fine.

good budget motor is a feigao 280 series motor, something like 3000-3500 kv would give you decent speed on 2s, plus the motor has a 2.3 mm shaft, so the stock pinions will work. The mamba 25 motors have 2mm shaft, and are not strong enough for the detta's gearing. I have used both a quark 33 and mamba 25 on my minis and prefer the quark.

Actually, he needs one of the YC22L style motors as they have a 2.3mm shaft for the metric 48P pinions the Vendetta uses.

He can use pinions made for the MLST. They are also 48P. In the picture of my Mega in my MLST you can see I the two pinions from the different motors. http://www.rc-monster.com/forum/atta...8&d=1204310439. The HP-YC22L-5000 would be perfect too with the pinions you mentioned.

Which one of them would be good for 4s in my jammin buggy ?.

what do you think of this one for 4s medusa mr-36-2200v2-5

The MLST pinions aren't metric 48P, that's the problem. They're standard 48P, just like on all the Mini-T variants and RC18 variants.

The Hyperion Long Can YC22L features a 2.3mm shaft & a choice between 3900, 4400 & 5000Kv making it perfect for the Duratrax Mini-Quake & Vendetta and other vehicles requiring a 2.3mm shaft for its gear set and for those wishing to run on 6-10nimh cells or 2-3 cell li-poly packs. (we reccomend the 3900 & 4400 for 3 cell li-poly/8-10cell nimh & the 5000 for 2-3 cell li-poly/6-8cell nimh). The YC22L & Mamba 25 combo comes with stainless steel hardware and 3.5mm gold plugs ready to be installed. It also comes with adhesive filmed metal tape to be used on the back of the motor to block the rear vent holes for use in dirt/sand

What are you, a newB or something? Everyone knows the Mamba 8000 is the bestest motor you can get for anything cuz the high kV means it's powafulllllll!!!!!111!!!111!!!!!11!!! :mdr:

your funny :lol:. I was'nt sure because i have never looked at the chart before. I do know right around 2000 kv is the sweet spot for 4s. But they have two or three motors around 2000 kv . So i was'nt sure.

That's odd. I thought 48 pitch is standard "Inch Unit" and Metric doesn't come in pitch, but module. So it'll be like a MOD 0.5. I'm lost, help :lol:. Anyways with 2S and the 2.3mm shaft, I would go with the HP-YC22L-5000, but I would also look into a Neu 1107/1.5D (8500Kv) with the 2.3mm shaft option.

Not for the little guys. The sweet spot is above 50000rpm so 4S lipos I would look into a 3500Kv. We are still talking about 1/18 scale right?

I just noticed there longest motor is only 60mm long. My 9xl is over 70mm long. Would,nt that affect the amount of torque ?.

Lutach, you're correct in the modules and pitches thing. The Vendetta and Vendetta ST use Mod .5, which is "48 pitch metric" (that is what most people call it; it is in use on Tamiya vehicles such as the TT-01, but it is not the proper term).

I use Tamiya pinions on my Vendetta ST with a 430L 3550kv align outrunner motor. It's geared 19/45 on a 2s apogee 1500 magnum pack. With all the settings turned down on the quark 33, it still has tons of scoot.:mdr: (<- that's my face every time I grab some throttle)

Ok, so I do know a little bit :yipi:. I have 4 of the Align type motors, but mine I think are 3600Kv and I'm going to try something Eliica type R/C car, but instead of 8 wheels, I'll try 4 wheels first :lol:.

I've got a lot of hrs on my Vendetta and run 2S lipo. Breakage probs seem to start happening when you get above 3500kv. I run stock cvds in mine and other than having to CA the drive pins into the ends of the cvds have never had a prob - I did upgrade to alum outdrives, only other thing I've needed to do. Stock gear diffs won't take the higher kv. I got over 2 yrs running stock gear diffs using a 3500 CoolRed heli motor. Caught the ball diffs at 1/2 price and made that change just cause it was too cheap not too, but could have stayed with stock diffs.

I got some of the 1st DTX cvds came out that were absolute junk and are still bummed out about how lousy those were. Modded a set of cvds using alum tbg and rc18 alum bones buy have not needed them.

I've fooled around with hyperion 5000, golden horizons 4700 motors in my Vendetta and MQs (I have a total of 4). I have a feigao 280 on my bench as my next project with a quark 33.

280L 3500kv 45/16 is not bad for bashing
GH4700 is a nice motor at 45/13 for racing
but the best is permax 400/4D 5200kv which unfortunatelly is no longer made so my second choice would be ammo 28-35-5100.
L version of hyperion Y22 5000kv is not bad either

Vendetta uses mod 0.6 gears. so if you pick a 1/8" shaft motor like ammo you can use tamiya mode .6 gears.
for 2mm shaft atomic makes pinions and for standard 2.3mm duratrax and atomic

Oops. Subconsciously, I was thinking about my Trinity NOW, which uses Mod .5; my mistake. (It's sitting under the bed right now, and I've been thinking about running it all week, but the spur is chewed up:gasp:)

I was wrong :oh:, but I was close and now I know something new :yes:.

To be fair, we were both wrong about something. And if I've learned anything from life, two wrongs make a right....sort of.:mdr: Hehe (I made a funny!).

I'm always learning something new. I like getting new updates. Too bad I can't find a hole to plug a USB cale. I remember watching a show on the Science Channel of a guy controlling a PC with his brain.

I think I saw that, or at least something similar. One day that will be a reality; just download an "update" and voila! You're an engineer now! Our brain has freakish potentials. And now back to our regularly scheduled thread. Hehe.

I just got the Hyperion YC22L for my quake and it's awesome, way better than the 4200 and 5400 mamba. It cogged constantly. Believe me, I tried both and wasted my money. I should have checked with BPP first. They're recommended setup were perfect. I'm running it with a 16T 2.3mm pinion and heatsink from TheToyz.com

Ah yes, but there will never be a way to update a slow witted person.

We could always try.:mdr:

To bring things back on topic....
I found what I hope is a decent bundle from a reseller here in Sweden:
ESC: http://www.himodel.com/electric/HiMo...R-FLY-30A.html
Motor 5100KV: http://www.himodel.com/electric/HiMo..._B2040-6T.html

I hope it will be OK for my use, I need to get a few new pinions though, any ideas on what range to aim for ?

That motor's a little small for a Vendetta I think. The Vendetta uses 28mm diameter motors. That motor is 20mm. I don't think that little guy will be able to handle the heavier Vendetta without overheating. It's even shorter than a mamba 25 motor by 5mm, and I'm pretty sure even those guys have issues with the larger minis.

If you are set on using that setup though, I suggest starting with the smallest pinion, and working your way up. You probably won't be able to run too large of a pinion with that motor at all. Now that I think about it, I'm not sure how it's even going to bolt up to the Vendetta's motor plate either.

You could try this one http://www.lightflightrc.com/HTML/pr...RC-28-47-1.htm. It has a 3.17mm shaft, is a 4 pole and the magnets are wrapped with Kevlar. If any of you go with them, tell Dave I mentioned his products to you guys :lol:. Also, look into these: http://www.highendrc.com/index_ecat.php?cPath=8.

Wow, that's one freak of a motor in your first link. Probably has tons of torque from the 4 poles and it being 47mm long. The second link isn't working for me though (or it's just taking a LONG time to load, but I'm on a cable connection here at school, so it should load relatively quickly).

I heard the plane guys are using that motor for up to 1000W in their planes. Try this http://www.highendrc.com and look for the Brushless EDF motors, not the 600 though.

Link's still not working. It's trying to open the page, but it's taking a VERY long time. Still hasn't opened it yet either. I'll try later and see if that helps.

1000w is crazy out of a small motor like that. What the heck do they use it for, pylon racing?

Edit: Link works, just took a while to open.

Sorry, I linked to the wrong one this is what I have on order:
http://www.himodel.com/electric/HiMo..._B2835-6T.html

I think that guy testing that motor was uning it in a EDF plane. Here is the link for more info: http://www.rcgroups.com/forums/showt...630759&page=69. Look at post # 1022 and the guy said 1300W, by his calculations. Post # 1008, Dave even mentions another motor on 8S that draws 1100W.

Much better size wise. I'm betting it'll be a handful to drive. It's definitely not going to be a slow vehicle at all. Max efficiency is only 81% though, which makes me question whether or not it'll run hotter than most other motors. It's a cheap combo though, so I think for 50ish bucks total to go brushless, you still can't go wrong. Nothing a heatsink can't help keep in check probably.
