Hi guys, couple of quick questions.. I am actually looking at a T4GRS but there is very little info on that:

1. Is the fastest mode for the px TFHSS with the 304 receiver?
2. Is this mode actually legal for racing (I though telemetry was banned?)
3. I see the tx is life or nigh, but the 304 receiver can run on Lipo correct? For nitro running!

Thanks!

Lipo is fine. In both the manual and Tower's product page, 7.4v/8.4v is listed as acceptable. I've been running an old rx Lipo in my 4PX for a couple months, been great. The 1850mah LiFe I was running didn't have the capacity I needed.

if the frsky are C1 mode like the 3pk ones, then they will not work

the best recv for the 4px are T-FHSS and those are only $49.99 new

Futaba recommends a LiFe batt. Why chance it on one of the most important pieces in your RC collection. Especially when the LiFe batts are less than $16...

I have been using these in my 4px and my sons 4pls without issue.

Hello everyone

I am going to buy a radio today and it's down to futaba or specktrum my question is how user friendly is the futaba vs the specktrum. I've used the old specktrum Dx3r pro for last 3 years so I am comfortable with it but I want something new. Any help would be greatly appreciated since I am buying the radio today.

Thanks
John

Futaba Support,

Hello, I have a 4PX that I use in offroad and onroad racing. Since new a few months back I have a stuttering servo problem. If I crank the wheel back and forth quickly it seems smooth. If I move the wheel back and forth normally and even stop and hold, the servo seems to want to jump around and is real jittery. I have tried both the stock receiver and the 204GF-E. I have tried multiple servos: Xpert 3431, Futaba S9351, Orion 1409. I have set them all to analog as well as digital with the same results. Tonight I upgraded to 1.1 and still the same. I even tried putting the ESC in the #1 slot and the servo in #2 slot and used the my throttle finger to steer with the same results. This gave me the conclusion that it is not the wheel. The throttle and braking on the other hand is really smooth.

I am at a loss. I have raced for over 20 years and have used multiple transmitters. I recently had the KO EX-1 for a year and the Spektrum DX3R Pro for the 4 previous years. I don't think I am doing anything wrong.

Is there a setting I should check or something I can try? Is the response just so quick the it makes the servos jittery or stutter?

Thanks for the help,

Troy

I held the 4PX in my hand at the Hobby Shop on Sunday and oh my god! I am getting this thing!

Anyways a question for the Life Battery. Protek shown below. I don't right now have Life capable charger as I have the LRP Pulsar 3 and older Turbo 35 GFX.

So to get something low cost with this capability what is good way to charge this? I only see Life batts as this and receiver pwr pack for Nitro cars.

Also do you charge in the Futaba connector or Balance connector?
