Ok I had glitches as in the car deciding to go full throttle for a second when I was braking or just not doing what I wanted as in turn a second later like I was locked out, I managed to fit a 2300 mah life pak instead of the 4 AA's, as I was nailing the AA's, same issue so I rotated the antenna, same issue except this time when my car for a brief second didn't respond I looked at the signal strength on the radio, it was at 0.
I haven't tested the update yet am hoping that that will work.

Receiver type?????
Nitro or electric????

Page 116 of your manual tells you how to do delete things.

Try to set the servo type to analog
I hear that wil take the gliches out.

I run 3 classes, SCT, ebuggy and Nitro truggy. I've always ran a protek life pack, and all running a R304SB RX. On the truggy I'm also using a temp sensor. I have practiced one night and raced 2 race days with all 3 vehicles and I have only honestly remembered to turn the antenna one time, but I have never noticed a glitch. I have charged the battery before each of the two race weekends. Every time I have used it so far it has been inside an indoor steel building. I ran a 15 min b main and a 30 min a main with the Truggy this past weekend also with no glitch.

I also have not done the firewire update since I seen some people who thought they had problems after the update. I hope my luck continues, it's a 3 1/2 hour drive to race for me during the winter months. It would be a long drive if I had to be trying to figure out radio problems.

Thanks for the data points.

Did you purchase your 4PX recently or is it one of the earlier pre-order units?

I suppose without s/n, the answer to my last question may or may not help pinpoint an issue there.

Just curious.
For those who are glitching, was it with the FHSS receivers or the FAAST receiviers?

Used my 4PX for the first time last week in a race with the 304SB-E receiver, and everything was fine. Std Life battery pack too.

I ordered the radio from Tower Hobbies on October 2nd and it was on back order, it shipped from Tower on October 17th. So I would guess it was the second shipment since people had them before I had ordered?

Hey everyone, my apologies in advance if this has been discussed, I sifted through all 64 pages and tried a few searches but, didn't find what I was looking for.

I'm considering getting the 4PX. It would be to replace my Spektrum DX4R Pro. I'm a bit confused with the FASST and FHSS protocols when it comes to which is faster.

I want the fastest and smallest receiver possible. Which one is it?

T-FHSS Fastest

R304SBE

FHSS. Faster and only $40 per Receiver

The 304SB(the receiver that comes with it) and the 304SB-E are the fastest response time recievers for the 4PX. As a happy coincidence thay are also much cheaper than the older fasst recievers.

The FHSS has the fastest response time and the FASST have a better secure frequency hopping.


I think that’s how it was explained too me last week.



The R614's (FASST) and the R304SB (FHSS) are the same size as each other.
Dimensions: 1.38 x 0.91 x 0.35 in (35.1 x 23.2 x 9.0mm)

whats the difference between the 304sb and the 304sb-e?

the -E has no external antenna
