Wouldn’t it be the same as the v3.0 installation? There is a nice tutorial with pictures on this forum. I don’t know how to insert a link here, just search for Installing the Spider V3.0 “Red Back” in a AWD chassis.
A little slower on the dyno than the UberDash.
UberDash = 41 kph
JetDash = 37 kphBut… The modified Jet Dash seems to have more torque than the UberDash.
Both have a very smooth power band, but when floored from half speed, the modified JetDash seems to lunge forward. It looked like the rear of the car actualy came off the track for a split second and then the car was at the end of straightaway and tumbeling end over end.I just wish I had a way to actually measure torque. AtomicMods has a new toy that measures rpms and torque and they have nice graphs for most motors on their site as well as an article on the subject at http://www.atomicmods.com/Categories/Article—Interpreting-A-Motors-Power.aspx I know the guys over there, and if I send them the 2 motors they may be willing to test them both. But I’m not ready to part with either as I love them both!
In short, the UberDash is a great motor, but this modified Jet Dash may give it a run for its money on a shorter course. Will continue to play with both and see if one is clearly better. Although that is more a matter of taste!
Thanks again ph2t for all your insight and for the UberDash!
Cheers!:beer:
Couldn’t get the camera to focus in on the armature. This is the best I could do…
Its still breaking in. Got busy today and had friends over for the last five hours, so I neglected to keep changing the batteries all evening. Now the kids are in bed, so its time to play 😉
Will follow ph2t’s directions but will need some help.
How do I polish the commutator?
What about my rotation problem? Are the magnets on the opposite side of the can than where they should be? Will likely open can to switch mags to opposite sides (or swap for original Jet Dash mags as suggested), so will post some pics.
Carbon brushes being broken in are fresh PN Racing brand. So I got that right!Although I have most of the Tamiya motors, I don’t remember what the guts look like.
Can’t wait to get it in a car on the dyno and then the track. Hopefully tonight! :smiley15:
Decided to build it since the wife is out for a while. Used the Tamiya Jet Dash armature, a PN BB can with new endbell, Atomic neo mags. All just laying around still in the plastic. The motor is breaking in now and I will post results once I get it in a car. If it is worthy it will need a new name.
One interesting thing is it spins in the opposite direction than my other motors. While looking at the shaft from the front of the can (the end the pinion goes on) my motors spin clockwise. This one spins counter clockwise. Guess I put the magnets in backwards? Will have to do some research to figure this out. Any help is appreciated.
In the mean time, any suggestions for a cool name are appreciated…

Don’t mean to hijack this thread, but…
I understand the Jet Dash is one of the best/fastest/badest Tamiya motors. I have a couple sitting around and was wondering how they would compare to the UberDash if the Jet Dash armature is used in place of the Ultra Dash armature. Has anyone tried this???
Hoping ph2t can weigh in on this. Thanks!
Thanks for the tip ph2t. I love that motor!
So far its only done time in an XMODS EVO with a Spider v2.1 and an 8 tooth pinion. Will try it in the Gen1 v4.0 soon, but also with an 8 tooth. I just prefer the smaller pinions and the UberDash is plenty fast with the low gearing.
No AWD. Used to have it in all my super fast cars. But after I got an RCP track I realized its no longer necessary. Cars have pleny of traction and run much better in RWD with the right tires.
:beer:
Haven’t done that yet, but built my first UberDash and broke it in last weekend. Man is it sweet! Think it hit 37kmh on my dyno. Nice and smooth, not to mention fast, on the track. Can’t wait to put it in my new Spider 4.0 Gen1. Thanks for the tutorial on the UberDash ph2t!
:beer:
I was proud to be the first in North America to buy the v4.0 Spider. Ordered 3 and they arrived on Monday. Got the first one installed today in a Gen1 XMODS and it is sweet! Haven’t had a chance to “really” test it yet, but the size is incredible. Here is a pic. Can you spot the spider?
Once I clean up the install and shorten some of the wires, I will put it through the paces. So far, with only a Speedy 07BB and a few minutes on my track, I’ve lost tires 3 times. Guess I’d better glue them on before I pop an UberDash in.
Nice job shrinking them Aaron. Enjoy!
The latest and smallest spider v4.0 is due out any day now. I’ve been waiting anxiously for a couple of months for them, but there has been some delay as a result of a problem in manufacturing. See Aaron’s thread about the new v4.0 under technical. I’ve used the v2.1s and they are awesome, so I have high expectations for the v4.0!
Just keep an eye on the store (I check it daily) or on eBay. Would attach a link here, but don’t know how!
Thanks for the advice. So far I have done a 2×2 and a 2×3 stack on Gen1 Xmods and I love the results! I don’t even need to use a “hot” motor because the stock motors really come alive with these FETs and are plenty fast. Think the 30 SP8M4s I bought may not be enough!
I’ve had similar questions about FETs. Not the technical stuff, just whether I should go with 2×2 or 2×3. I bought some SP8M4s from Aaron for use on Gen1 Xmods and MR02 Mini-Zs. So far I have done a 2×2 and 2×3 stacks on the Xmods, and WOW!
Not sure about the current, etc. but the 2×2 stack made the car fly with a stock motor (Speedy BB05) and the 2×3 stack made my second car REALLY fly with a Speedy BB07.
All I can say is I love these FETs! Do a search on this forums for SP8M4 and you’ll see what others have said.
Can wait for the Spider v4.0!
While waiting for new Spider and Bug, I ordered 30 of Aaron’s new SP8M4 FETs. Started with a 2×2 stack in a Gen1 Xmod. Max speed only increased a couple of KPH on the dyno, but on the track the car had much better acceleration throughout the powerband. Its pushing a PN Speedy 05BB which now feels like a Saber or Xeric. So I’m pretty happy!
What to do next? I have several Gen1s as well as some Mini-Z MR02s and an AWD. Not sure which cars will benefit the most with these FETs. Also not sure what the ideal stack size is for these cars. I know the more the better, but I won’t be running insane motors, just some Atomic Z2s, T2s, PN Animas, Xerics, Sabers, etc. Can anyone help?
Thanks!
Sounds great! But WHEN will the v4.0 and the Bug be available???
I still have a new Spider v2.1 and I plan to get some v4.0 and a Bug. Can you help me with which cars they are best suited. Looking to upgrade an XMODS Evo, Mini-Z MR-02 and an AWD.
Hate I missed the 3.0 reign.
Thanks!
Yo Aaron! You’re killing me man. The black widow and bug sound great, so when can I get some???:huh:
ph2t,
What an honor! I’ve followed your happenings on the forum and you are clearly the master.
To answer your questions, I’m running NiMH (Its my understanding that the spider and lithium are not compatible on the Gen 1 Xmod). The batteries were not really warm, just the spider, and when I later tested the batteries, they still carried a charge. The car was acting as if the batteries were running out of current.
I am using an 8t brass pinion. When I removed the Anima II from the car, I checked it for binding and found none. I then hooked it up to 2 NiMH cells and it ran fine. So I reckon the motor is OK. (side note – the three new PN motors have very cool open endbells, but different than those on the Atomic motors)
In summary, the problem only occured when the Anima II was in the spider car. I’m at a loss! :huh:
As for performance, its hard to say as I only had goodperformance for a few minutes. The Anima II appeared faster than the previous version on the ground, and seemed to have a smoother power band. But I haven’t gotten it on the dyno yet. Will do once I get the spide problem worked out.
Any advice would be greatly appreciated ph2t…
Aaron, or anyone else that can help.
I put the new Anima II in my Gen 1 Xmod equipped with the v2.1 spider (which has worked superbly with other hot motors like the PN Anima, Atomic Z2 and T2), and the spider got pretty hot after just a few minutes of running. The batteries also seemed to be out of juice at that point because the car slowed noticably. I couldn’t find anything wrong with the set up, so I switched back to the Atomic T2 motor and the car ran like a champ.
Could it be that the Anima II is too much for the spider, or may something else be going on. Please help!
