Hopefully we can get some practice in late this week if we are not rained out....

how long does it take to get a RMA# from tekin?

If you email [email protected] during business hours requesting one, it usually only takes a 5-10 minutes unless I am busy driving on the test track.

I emailed yesterday, probably why i haven't gotten one yet.

A voltmeter may not catch this quick of a voltage drop. The cap should correct the issue mind you. You don't even need one that large. A 1000uf 16v cap would do it, readily available at a Radio Shack,etc.
Spektrum part # SPM1600
The servos are known to be power hungry. What you must understand is that the BEC has to power the receiver, servo, personal transponder, external fan if equipped, and sensor system. The servo shouldn't be pulling that many amps anyhow.

Sorry for this being a bit off topic but the input to this thread seems to be better than most, and it seems that others are having the same problems.

I have exactly the same issue, receiver is browning out just by fast turning of the steering even with the car on a stand and no throttle. My set up is RX8 on 4S, Spektrum SR3500 receiver and Savox 1256 servo. I have also tried the same servo with an identical receiver but Orca Vritra ESC from my 410 and it is the same. Does/can a servo draw the same current with and without load? I take it that the receiver is like throttling the current somewhere and then causing the brownout? Will a glitch buster resolve this or would it be better to change radio?

I had a problem with mine dropping out and not counting laps. I had a cap on mine and it did not improve the situation. I had to get a Castle BEC to fix mine. Airtronics receiver and a Savox 1257 are my gear.

Are the brown out issues with Savox servos isolated to Spektrum receivers? I have to run a cap on my RS with a Savox and Spektrum. . I'm now switching to a Futaba radio and want a digital servo for my SCTE. I run a RX8/Pro 4 on 2s. I like the Savox bang for the buck but don't want to run any external caps. Would I be ok with RX8/Futaba and Savox servo? Thanks.

RX8 ESC
Hi, I bought a used Tekin RX8 ESC and motor T8(1900KV) motor.It ran good for 2 lap and quit. When I pull the throttle the led`s light up all the way accross and if I hold the throttle , all the led`s are flashing. When I turn the esc on there are no chimes,and I cant calibrate the esc with the radio or even reset the esc. I have a new airtronics receiver in the buggy and the servo works good, and a new battery fully charged. HELP
