Have you clean the pins inside the receiver ? It's difficult but you can do it with tooth picks, cotton buds, autosol, alcohol and be patience.

um not to pour oil into the fire, but i do agree even thou the 101 is a esc, it's still an entree level ones.

As for the jitter, i'm not to sure what the condition of ur stuff is (no offence). but is would do the following:

1. pull all electronic out of car(if not done), and just run it as it is.

2. check receiver for dust, debris, dirt, carpet linen, etc (get some one to open up ur receiver and clean them up if u dont know what ur doing.)

3. check all wires, if they are expose then insulate it (same with the anntena wires).

4. try different motor or put some caps on the current one.

5. try another receiver/esc combo

6. if all else fail, go to ur trusted lhs and ask for their help.

I'm a bit confused by this. How is it you have the ESC plugged into all 3 sockets of the receiver. I went to the Tamiya website and the TEU-101BK has only one standard receiver connector ...which should be plugged into "channel 2". Your servo should be plugged into "channel 1" . Nothing should be plugged into the BEC socket unless you're using a personal transponder or some other external device like a motor fan. Check the wiring on the connectors. JR has often required you to change the position of the 3 wires. Check your instruction manual for the receiver.
Also, are you using a standard Tamiya Silver Can motor ?? This ESC is only rated for the Mabuchi or Johnson can motors like those supplied in many Tamiya kits.
Last...check your crystals and possibly replace them. Is the Hitec receiver a "Dual Conversion" unit?? If so then you must use the appropriate dual conversion crystals.
Hope this helps.

oops! by plugged into all 3, I mean my Tamiya ESC is plugged into 2 of the holes and my servo into the 3rd.

as for the BEC socket, the Tamiya ESC *specifically* states that it should be in there or it might fry the receiver. And so I did :P
when I plugged in my Novak ESC (which only needs one channel, no BEC connector), it also did strange things, and it had a different motor connected to it.

so the reason I think it's the receiver is because, I had 2 speed controls with a different motor connected to each. Both glitched the same (or in a similar way).

can you mix and match RX/TX combos?

Here is the hottest motor TEU-101 can safely run without fry problems: Tamiya Sport Tuned ( black can ).

A friend of mine use TEU 101 with 27T stock motor and it fried

Isn't that ESC BEC cable should be plug to Rx batt ?

already did that (plug in the red plug into the receiver).

I've been using silver cans for these tests with both my Novak and my Tamiya speed control.

Anyways, I did a test where I setup the car like a nitro car (BEC with 4 cells plugged into that slot, and tested each channel with a servo). the servo moved fine for both channels (I did it one channel at a time).

edit: just tested with both servos.
so I have two servos. one is a Futaba servo, the other is JR.
when the Futaba servo is plugged into CH2, and the JR is plugged into CH1, the Futaba servo tends to glitch like my motor does.
switch them around, and suddenly everything works fine!

The ESC you have has more than one connection to the receiver ?? In the picture on the Tamiya website, all I'm seeing is a standard single 3 wire plug?? Does your ESC have another plug?? Is it Red and does it have 3 wires or just 2 ?? Does this ESC have a on/off switch ??

the Tamiya ESC is the same one as the picture. it has:
one battery wire (with Tamiya connector)
one black plug with 3 wires (Red, white, black)
one red plug with 2 wires
Has a big on/off switch.


Anyways, I took it to my LHS and apparently it is my receiver that is messed up. For whatever reason, I'm not sure, but I suspect it to be that I didn't plug in the red plug from the Tamiya ESC into the receiver right away, possibly frying the RX or atleast messing it up enough that it's in RX heaven right now.

But ... I'm not exactly sure if that is the TRUE cause...

Apparently your esc does have a connection to the Battery slot on the receiver. Before you're convinced it's the receiver, I'd try changing crystals.

well, went to my local hobby shop and we tested a few different receivers and stuff.

The crystals are fine. the minute we plugged it into another receiver, everything worked fine. so my receiver is busted.

Anyways, I replaced it with a used Futaba receiver. Hoping to utilize this receiver to get a better radio.

But I guess what has me dumbfounded is WHAT exactly caused my receiver to die like that? I highly suspect the Tamiya TEU-101BK

So I just reinstalled the TEU-101BK on my car again, after I took it out to put my Novak Elektra in.
My old Novak Elektra is rated at 5.0V and 0.5amps. Ran the TT01 pretty decent.
Then I installed the TEU-101BK... MAN! This thing must be running at 6.0V! because suddenly my servo transition speed was noticeably improved. And the motor seemed punchier!!

Now here's my question: I got a Trinity P2k. Will it fry my TEU-101BK?

I know someone mentioned that the 27T fried his buddy's TEU-101BK... hmm... maybe it's gearing?

welcome to the board. And thank for the info!!!
Much appreciated!!

But if this thing can run 19T and 12T motors without frying, does that mean that it can run stock 27T no problem?
