My 3PK sets off an alarm (that doesn't stop, screen shows low battery) when tx batt voltage reaches 8.5v. Manual warns not to operate tx below 9v. So its prob between 8.5 and 9v.
I never let mine drop below 9.5V. So it is definitely an overheating issue. I swiss cheesed my radio box to try and fix this issue the first time around, now I don't know what to do other than buy a new radio system or possibly Spektrum module. I love my 808, but I think it may be the radio box location. I haven't had issues with overheating in any other models. While I like my 3PK, I don't find it THAT amazing that I'd completely rule out changing to something else. I get that the 3PK was the benchmark of radios for years, but I'm starting to get better and don't want to be retarded by my radio equipment.
Is the regulator in the radio box with the receiver? If it is try mounting it outside the box to get the heat away from the RX.
Have you also tried running it with a std. Nimh battery to rule out battery/regulator issues?
Are you also running a switch on the battery or plugging the reg. straight into the RX?
All of these have caused issues with other drivers and looked like an overheated RX when the RX wasn't really the cause. How old is your RX? If it's the blue label one then it's the first version, there has been an update since the blue label. If you send in your RX, Futaba will update it to the latest version.

It happened before I switched to lipo. My regulator is outside of the radio box. The reg plugs directly into the RX, and has a micro-deans on the battery end, and the lipo has a mini deans. I just plug it in before I use it and unplug after every run.
Well, it's been a fairly long time since I've posted, but here goes. This time, I'm asking the questions!
I use stick radios, and I generally use my 3VCS or 3VC transmitters. I have 2.4 FASST modules for both, and what I'm querying is this:
Why doesn't my 2.4 system seem to work with the SFL-10MG servo that came with my Baja 5B SS? I'm running in PPM mode, but only my Hitec 5925 (digital) seems to work. When my SFL - 10 servo is connected, it doesn't matter which channel I connect it to, the servo moves rhythmically from endpoint to endpoint, with the R603FS receiver flashing Red/Green.
When the SFL is connected to a 40FM receiver, it works fine.
I've tried both the 3VC and 3VCS with 2 separate PK-FSM2.4G modules. All besides the Tx's are brand spanking new and unused. The problem occurs each time.
This seems to be a specific problem to do with the FASST system and the SFL - 10MG servo. I was under the impression that the system should work fine with analogue servos provided that you run in PPM mode. But I've had no luck so far.
I'm hoping that I don't have to revert to 40FM, as I only have 1 PCM receiver left. And I don't want to buy another digital servo - this time a 1/4 scale size jobbie.
Any ideas guys?
Regards
Horatio

5 posts in 5 different threads that say the exact same thing.. REALLY??
But I'll try to answer your question.. I have run in PPM mode and run 1 digital and 1 Analog servo with no problems. My guess is your radio is in HRS mode for the model you are choosing.. The 3pk is set for each car so that you don't have to switch from PPM to HRS each time you switch models. I am guessing you have switched from HRS to PPM while on another model. THen switched to the Baja 5b which was still set at HRS mode.. Hence causing the problem you are stating. MY understanding though is that HRS will burn up analog servos due tot he constant search for the optimal location. WHich I am guessing is exactly what your analog servo is trying to do..
Hope this helps..

Futaba 3PKS w/ FASST 2.4ghz
hey guys, i just ordered the 3pks fasst 2.4ghz, can you tell me what the 3pks has over the 3pk?
3PKS has a slightly different menu and a center knob for scrolling through, where the 3PK uses up/down buttons for scrolling. The 3PKS also had a few more features. The performance of the systems themselves function the same though.
