Good For You.
 

Hey Sikes great go on teh gears for the damaged servo gears. We expected at least that much for the problems you had. Of course now you know they will not hold up in your rig with that motor. As far as the MG995's I have not tried them either, but like stated earlier for $22 what have you got to lose. We do hope that you have better luck with the diff gears setup the other way. It would be nice if you could get this thing set up in a configuration that will allow you constant use without failures. Good luck with the changes and keep up the good work.:yipi:

I run the MG995's on all my traxxas trucks and TXT-1. Best servo for the money....and with 170 oz tq, its hard to beat.

170 oz's of torque? :surprised:

Aren't the stock 2055's and 2056's only rated at 80oz?

according to this calculator, which i just found and is pretty handy by-the-way, it's 200 oz at 6v! (converting 15kg/cm)

Yup, I even tried the upgrade from Traxxas the 2070's and they are no match for a TXT-1. Swapped to these and they will move the truck if its up against something...hehe

Wow! Great!

One of these should be stronger than both of the stock ones. By using two of them at 6v, turning fully from stop to stop at a standing still should be no problem at all.

:yipi:

NICE! But you need some real tires on that thing.

Actually, I kinda like the new improved E maxx tires. They are stiffer than the originals and don't seem to swell as bad.

Real Tires? Got any suggestions?

On the point of servos, I bought a couple of these a little while back, supposedly rebadged MG995s, as an upgrade to my HS645Mgs. My god, never have I seen such poor quality servos- only about 30* of throw in either direction, and they wouldnt hold center/neutral without constantly buzzing, and thats without bolting them into the Gmaxx. Hopefully though you will get genuine MG995s and not some rebadged junk like I did (which I ended up reselling for a small profit, thankfully).

I see some subtle differences in the casing designs when comparing the two. So I hope these will be better than your experience.

I'll find out soon and post the results. :yes:

I bought a pair of them last night, so i will try them too. Could not pass up the deal, even if they go in a pede!, or see use as a brake servo!

These must've been what I ended up with - it's been so long I can't remember now :oops:

Your symptoms sounded just like mine- I was bitterly dissappointed too. Hopefully Sikes will be the real deal though- different case design sounds promising at least.

I got the Servo's in today!!! :yipi:

Got them installed and am topping off my Lipo's now.

I set the truck down on the carpet, they will quickly turn stop to stop with no hesitation. Much stronger than the stock ones! :yipi:

I don't sense any jitter at all.

Looks good so far.

I'll run it in a few minutes. That will be the true test. :yes:

:yipi::yipi::yipi:

These Servo's are GREAT!

I detect no jitter. They are MUCH more powerful AND faster than the stock ones.

I rate them a 10 on the "money well spent" scale. :yes:

I'll probably be getting some more soon.

Let us know what you think Linc. Like I said, I don't have any experience comparing servos really. But I can't imagine those $100 each servo's being much better than these. Very satisfied here ! :yes:

I've got six of these, you can't get better servos for this price. Two of them are running on 7V for over 3 months, they are still working well, have got tons of torque and are fast.

I have 2 on the way and now to sell my water proof ones and buy some more

I did some changes and made another run.

I changed the 22 tooth pinion gear over to the 25 tooth mod 1.

Then changed the 40 tooth spur over to the 36 tooth spur.

The AXI 2826/10 motor still handles it fine. Top Speed is noticably greater. BUT........there's the "word" again.

Cogging is there but ONLY on startup. Any rolling speed at all and it's gone. The old 1/4 throttle blip does the trick to get it going.

Runtime is down.......came down from 25 minutes to about 20 minutes
Motor temps are up........probably 150-160 range.
Lipos are pretty warm........100 range
ESC is cold.
Ambient is 58 degrees outside today.

I think the better setup will be the 2826/8 with a 22 tooth pinion/40 tooth spur. We will soon find out. :yes:

So, you are going to a higher kv motor and back to the gearing that worked well. What kind of speed are you expecting?

I know, I am lazy, I could plug it into the speedcalc, but I am sure that you have already done that.

4S with the new motor will top out right at 30mph, but on 6S will go up to 45mph.

This all depends on temps of course. Perhaps 5S will be the sweet spot at 38mph.

This setup really has some good acceleration. Makes for a fun basher.

5s sounds good, I may have to try out the higher kv axi. I will do some more testing with the hacker 15l befoer that though!

Well the AXI 2826/8 motor came in. I got it installed.

Took it outside to try it, and I can't tell anything really. It's been storming ice here for the past two days. My dirt mounds are hard as a rock and all the maxx wants to do is spin and throw ice chunks around. :cry:

On the brighter side, it does appear to be alot more aggressive with this motor. It's going to power it really good. The only thing I'm curious about is motor temps.

@Linc,

Where did you get those heat sinks you had attached to the Monster Pro I got from you? What did you glue them with?

I'm thinking about installing a square heat sink over the open mounting hole in the motor plate, then attach a 25mm fan to it. This will help with temps in the motor AND clutch department at the cost of only .5 oz.

That esc actually came to me with the heatsink on it. I found some similar on ebay. Those had a sticky thermal pad, which is porbably worthless. I would say some arctic silver would do the job for sticking the heatsink to the motor mount.

Are you running the cooling fan on the axi? Is it getting too hot?

Yes I'm running the cooling fan on the motor.

I'm not worried about temps with 4S, but I would rather prepare to keep temps under control on 6S. It's gonna kick butt. My 6S battery setup is 5000mah, 20C and weighs 14.2oz. With 6S, the motor will be carrying more of a load.

The fan pulls air through the windings, which on the 8 turn, there seems to be a greater amount of air moving. The stator poles aren't quite so full is my guess as to why, plus the higher rpm's.

The fan takes care of endbell temps and the surface of the windings, the rest of the heat goes out through the motor bearing holder and into the mounting plate.

I need to block off the other motor hole in the plate to keep dirt out of there anyway. Why not turn it into something good for the setup? :yes:

Do you run with the spur gear cover on? I never bother, as my body usually keep the bulk of the dust/grime out. Pluss I like to be able to see the gears.

In the beginning, I didn't. But decided to keep it on there.

The mod 1 gears are great and showing no wear as of yet. I figure dirt getting caught in the mesh will cause the most amount of wear. Keeping the cover on will prolong the life of the gears.

I'll open it up every now and then and take a peek though.:whistle:

I took the endbell off both the 10 turn and the 8 turn to do some side by side comparison. They are twins except for the fact that the 8 turn's stator poles look like a good balance between fill and just enough space for good air flow. The 10 turn stator poles are just as full as possible.

I wanna do a Traxxas Villian Boat with a pair of these AXI 2826/8 motors, a CC BEC, a pair of MM ESC's, and a 4S 10,000mah Lipo setup. They have enough torque to get it up far into the "fun" zone.

HAHA

That think will fly. I can't see the supervee motor being as powerful as one of those axi motors. You should easily get that boat over 50mph, which will be ridiculous. I hope the boat can keep up with that kind of power. My supervee's hull is completely out of the water at 42mph, I really can't see it going any faster and still stay upright!

Do you have the boat yet? You might be able to get away with the sidewinder esc, it is half the cost of the mm, just not sure if it is 4s capable? You can set the lvc to the same values as the mm so it should be good for 5s! I got mine for 65 bucks from tower, that 130 for two and you may be able to get the axi motors cheap too. So far my sidewinder runs cooler than my MM did in the xxx-cr. Not sure why, maybe the heatsink is on better?

That boat would be wicked!

I have two MM escs now, but one of them has issues I think. I may send it in for repair. It will still run a motor, but I hooked it up to a Feigao 6xl one time and seen some smoke come out of it. So, I don't think I can trust it.

I've been looking into how to build a watercooled motor plate. I'm also putting some thought into how to water cool the esc's. I might go with something other than the MM's. I'm not sure yet.

I've been tempted to put the good MM I have in the E maxx. With the new firmware update, it just might do a pretty good job. Whatcha think?

No I don't have the boat yet.

I would stick to 4s, but give it a try. It would be nice to see how it compares to the quark after the firmware update.

I finally got a chance to run the AXI 2826/8 motor in this setup.

It outperforms the 2826/10 by alot. A pretty large increase in top speed. I don't notice any decrease in torque, but it does run cooler. I didn't expect cooler temps. I am going to contribute this to better air flow since the stator poles don't appear to be quite so "stuffed" as with the 10 turn motor.

The 8 turn spools up fast enough to put it on it's lid very quickly. Gotta kinda watch that itchy finger now.

Out of the two motors, the 8 turn is definately the way to go. :great:

Did you run the 8 turn on the sony cells or your lipos?

Glad to hear that it works well, and the temps stay in check.

I ran the 8 turn on the Sony Cells yesterday afternoon and just ran it on a Firepower 4S 5000mah 20C setup.

Runtimes are about the same with both battery setups.

I like how the truck handles with the lipos better. A little less weight does make a difference, especially in handling and jumping.


I am very happy with this setup. I believe it to be "track worthy" now. :great:

Got another Tower Hobbies order on the way. I put together everything to do the two speed kit with. While I was completing the order, the 13 tooth idler that I had on MY list, suddenly went on backorder. Ugh!

I completed the order though. I have a couple of complete transmissions in it for the New E maxx.

My next new project will be eliminating the slipper and going Direct Drive to input shaft with an outrunner setup.

If I can make it fit, I'm going to install the AXI 4120/14 turn! :yes:

It runs very cool and at 660kv, it should make for a Wild setup on 6S. Even on 4S, it should perform very well. It will be more of a top speed setup.

I just got done with installing these servos and they are great.......on the carpet stand still they turn stop to stop great........you can see the chassis flex some from the torque

I just took my Revo out for a drive. These servo's kinda have me spoiled from running them in the E maxx. I'm gonna get a pair for the Revo too.

They do make a big difference. :yes:

just wondering what kinda speeds u think u are getting with the 2826/8?

im thinking about trying them out on my emaxx. cause at work i get the kms ones but the same rating for cheap.

Here is my current setup plugged into Brian's speed calculator. It seems like it's alot faster I think. But maybe it's because it accelerates very hard and tops out quickly.

It is a really fun setup. :yes:

As you can see from the pictures earlier in this thread, it is a rather small motor. At only 36mm x 54mm, it's putting out some power.

AXI quality is hard to beat IMO. They use some of the strongest Neo Magnets around.

If you use a cheaper outrunner, it may not perform so well.

The AXI first appealed to me because of the optional cooling fan to help control motor temps.

I tried this on 5S and it just screams, but it was on the verge of overheating the motor even with the fan.

I think I found one of the KMS motors in this size: http://www.hobbypeople.net/gallery/108512.asp

Are there other turns available? I also wonder if the AXI fan would fit this?

yah those are the motors but i well be using a 2826/04. i get them for like 40$ and if they ever go out i can just defect it out lol and get my money back or get another one haha. (good thing about working at a hobby shop and your boss is really cool)

Heres the 04 motor like the 06you linked to. 1000kv!

Half the price of the axi. wonder if it is any good. You gonna buy one sike?

Hey that is a pretty good deal! :yes:

Can you get me a good price on one too? I wouldn't be looking for a warranty or anything. LOL

Got any pictures of the butt end of the rotating can of this motor?
