I'm not sure if this is the right place to post but i don't find another more suitable. So please move it if it doesn't belong here.
okie anyway, i got a HPI Pro4 and it seems my Pro4 was cursed by some radio ghost. I have nothing but problems since i got it
I got glitching problem with my SS5800 at the begining and after trying everything including buying a brand new 40MHz FM synth radio set, new servo, all the tricks and still can't fix the problem. So i finally give up and I put in a trinity monster stock pro motor + ESC to replace the SS5800 and it seems to be working fine .... for 2 days!!
Yesterday i took it to the local track for some practising, everything was fine when i was running the first battery pack.. then i put in my 2nd battery pack and start practising with my friend and after a few minutes the car start to lost control. At the beginning i thought it's just some normal radio interference as it happens to a lot of people at one far corner.. and i can still control the car fine in most of the track... but later on, suddenly i notice it's getting worse and i can't even stop my car !!! the steering still works but i just can't stop the motor. Finally someone caught my car so i took it back to my table and check what's going on. The steering AND motor are both moving randomly and i can't stop the motor even with full brake. There were quite a few guys on the track and I saw someone's playing some RC plane about 1-2 miles away so i change my frequency to see if it works.. tried a few different frequency and finally found one that is better (but still glitching quite a bit). So i put in another pack of battery and try it again.. it's better than before and at least i can stop the car now! but still somethings not right. Oh well so i blamed those other guys and went home. After i went home, i cleaned my car and test my radio again.. and the car still go crazy when i turn the power on!!! wait.. i notice one funny thing, the car go crazy ONLY when i turn the radio transmitter on! I tried many frequency and it's still the same. Almost no glitching or anything when the transmitter is off.. but the steering and motor will go crazy at random direction as soon as i turn the transmitter on. I've move the receiver around the car and it doesn't do anything at all. And another funny thing is if the transmitter's antenna touches /almost touch the receiver's antenna, then the car won't go crazy but also it seems the receiver can't receive any signal as well.
I install some new battery and still the same problem (the battery indicator says battery is full). I've resetted the ESC and still the same.
The radio is almost brand new and bought from the shop just before christmas (it's a korean brand). I remember the car would go crazy from time to time as well since i got this radio but it's just completely out of control now
i took the car back to the shop this morning but they won't have a time to test it for me until next week.
I can't find any 40MHz FM Tx/Rx that i can borrow so can't test the tx/rx separately.. so do you guys think it is my radio transmitter? or what can it be?
