Aquaspeed motor kicks butt!

[ph2t]

This motor rocks in an Epoch, simply put.

A stock Epoch with the Aquaspeed motor will beat a 4 cell, bug turbo & stock motor Epoch. No problems. See the video futher down in the post.

Some comparative specs.

Stock Epoch motor: 112 turn, 0.1mm wire (info from www.luckyyy.de)
Aquaspeed motor: 65 turn, 0.16mm wire

My ICE charger recorded the following.

Stock motor @ 3.6V is approx 130mA drain, no load.
Auqaspeed motor @ 3.6V is approx 270mA drain, no load.

The driver IC on your Epoch PCB will get warm, possibly hot! On 3 cells and no load, you punch the throttle back and fwd, over and over and the IC definately gets hot. But it appears to work a treat anyways. Add a bug turbo and it's just nuts! The bug doesn't break a sweat with this motor, even when running on 2P lipo, 260mah, 3.7V.


It just looks beefy, lol..........

Now check out this short 600KB video.

The red epoch is running an Auqaspeed motor, everything else is stock. The blue Epoch is running 4 cells, bug turbo & the stock motor. Not too shabby eh? :)




Here's the killer...

They're $9.90 at rcmart!

http://www.rcmart.com/catalog/product_info.php?cPath=144_666&products_id=15101

Hurry up and go buy it already! lol..

I suggest the shop here stocks up on these buggers, they're like the xspeeds of Epoch's.

Awesome! Wonder how it'd run with bearings?!

/me begins assembling an order...

Better yet, will ask track owner tomorrow.

[mod_o_matic]

They finally came! Is this the fastest of the Mini-Z boat motors? I am sure there was going to be more..

Finally, te epoch motor problem i solved!

[LBRC]

Now that's good news :) price is right too. :cool:
How is the low end torque/acceleration?

[arch2b]

i amde sure epoch saw this and i am sure he will have these asap as well :)

[ph2t]

It's ok, no super fantastic. I need to compare a fully stock epoch to the an aquaspeed stock Epoch. Then I'll know more. It does look to me though that a turbo is really needed to get the performance out of it.

I'll drive a stocker and a speed stocker around tonight and let you know :).

thanks for the work and input ph2t :D

Got any info about more than one kyosho mini-z boat motor dude?

I wouldn't say the problem is finally solved. Maybe a custom wind around the 75 - 90 mark would be good for this motor. I haven't compared the magnets between the stock or the aquaspeed yet either, so one might be stronger than the other.

Then there are also HO slot car motor magnets as well. Hey LBRC, can you get neo magnets for this class of motor? :confused: If you could that would be just :cool: .

Rcmart is always a bit more $ for most micro stuff. It would be great if the shop can score 'em cheaper..... But who knows, it's a relatively new part/model/rc.

You can get neo’s, sort of, they come slightly too thick and have to be honed down, not fun, they are also super strong, even stronger than 130 can neo’s fortunately the thinning down helps, the real killer is price at $18 a set. I have a set that has been modified to fit, lol, and a couple of Aquaspeed’s coming so I can give them a try. I have tried them with a couple of different armatures already unfortunately along with the greater torque you also get more drag so the low end stutter is increased too.

Ball bearings are pretty easy to install and worth it in my book for the slight increase in run time. Same size as the differential mod, but you have to get the spacing just right since they are thicker than the bushings. The endbell is pretty much a straight swap, jut be sure to use something to spread the brushes or you will waste a perfectly good motor. You can easily make a brush spreader by cutting the small “U” section out of a paperclip, insert into the holes and twist to spread the brushes. The can is a bit harder since you have to modify it slightly.

The 8-tooth pinions I got work, a little short but not bad, all you have to do is put an extra spacer under the motor and everything lines up just great. How does the shaft length compare to the Epoch motor?

BTW I have a motor that ended up being a bit much for the Epoch (call it sit and spin) but it might be something in a F1 boat, can a boat motor be too fast?

All i know is that from the videos from there, there should be more than on motor coming out. I am not 100% sure, but hey, at least there is one!
I figuar now that these motors are actaully cheaper compared to slot car motors it will be easier to get people to rewind the motors!

Yep, we're getting 'em! :)

FYI we can get any size Neo magnets made (need a decent qty in order to make it worthwhile); note that if we came up w/ something that worked well for Epochs, chances are it would also be of interest to the slot guys so that would help spread the cost and thus keep the price down. :cool:

WOW, my motor came in today, damn this thing is fast! I just tried it on half a charge, more of a review later.

Now all i need are some grippy tyres, Arch, think your friend would sell me a set? Thanks

[arch2b]

his member name on mini-zracer is .cooldragon

i an not comfortable giving out his email address without his consent however i will remind him to check this forum ;)

[arch2b]

any more reviews with the aqua motors?

[arfin]

Well i suggest you get a turbo installed with that Aqua, for torque and safety reasons. When i was running my Epoch today, it would just slow down for a few seconds i'm guessing because the Fets couldn’t take it. Also you will need the torque the Turbo gives you.

But so far i'm impressed with the motor, and recommend it!

[LBRC]

Just got an Aquaspeed to play with. Slaped it in a Epoch with a turbo and Kan 180 battery pack. The speed and torque are pretty good however even with the 180 mAh cells it draws a bit too much current.

http://lbspd.com/v-web/gallery/albums/album68/Aquaspeed_in_Epoch.jpg

As expected you get a noticeable shorter runtime, however what some people might not like is that on the track when the motor is put under a load it takes enough power away from the steering circuit to cause the steering to become erratic to the point that the car will slap itself up against the wall all on it’s own even when just accelerating down the straight. Switching to a 340 mAh Worly LiPo pack helped but did not eliminate the problem entirely.

http://lbspd.com/v-web/gallery/albums/album68/Turbo_180_with_Aquaspeed.jpg

Overall if you are just racing around the kitchen, garage, back deck, or tennis court you probably will hardly notice the steering problem so the motor would be a great choice, however if you plan to race on a RCP Mini-96 or other track especially with 2 foot lanes you will most likely be a little unsatisfied.

[arfin]

Hey i didn't notice that, i'll check it out today (i didn't notice because i don't race on a track)

[LBRC]

Would be very interested to here if you notice anything or not, especially since I was sort of looking for it, so it’s a little hard to be objective.

For electronic techies it probably would be more accurate to say that it’s a voltage drop problem, I guess.

I first started noticing it when with the LiPo packs even with a stock motor, although with them it’s a very gradual thing I‘d be in the grove pulling perfect laps but as time went by I’d start bashing the wall now and then and messing up on the turns, sort of like I was getting tired, however once I made the batteries hot swappable with the ability to just pop in a fresh pack it became apparent that even though the pack might have 20 minutes of driving left in it the steering would start to degrade slightly long before the speed dropped off. Even the balanced Spud type modified motors have the problem to some degree although it’s not quite as noticeable as it is with the Aquaspeed. Although since I only have one there could be a good deal of deviation between individual motors too. I haven’t gotten around to putting the Aquaspeed on the motor performance monitor yet either. It will be interesting to see how it does.

[arfin]

So far i don't know if it's my antenna or this problem. For some reason, my antenna screw doesn't hold tight, and the antenna wobbles, SO i don't think i have this problem you describe yet. But i do have a problem, where the epoch just stops for a second i guess for the fet to cool, and runs again.

FYI we have the AquaSpeeds in stock:
