Hello everyone - I'm new to the forum and am a complete nitro RC NUBE, and this is my first post. All I know about the REVO is what I've read in the manual and what is contained in the TRAXXAS CD. Here's my situation and I hope someone can help me sort out what I need to do:
I bought my REVO 3.3 quite some time ago, like 4 or 5 years ago? Can't even remember for sure. I had taken it out, broke it in according to the instructions, tuned it, and had run it a couple hours that first day. Then, life crap happened - company I worked for laid off all their contractors, so was without a job for a while and the REVO got shelved. Was only out of work about three months, but the RC hobby took a back seat to everything else that was going on at the time.
Fast forward to a couple days ago - I had a renewed interest in getting my REVO back in working order after sitting all this time. Initially, the receiver battery wouldn't charge but for a few seconds, but I ran it through 4 or five charge cycles and afterwards it seemed to be behaving just fine. I have a Venom temp/voltage monitor on the truck, and the receiver battery was holding charge as far as I could tell.
Took it out today, fired it up and re-tuned it. Again, voltage seemed to be holding up according to the monitor - didn't run the truck any further than 100 feet from me, just up and down the concrete driveway while tuning. The problem is, periodically, out of the blue, I'd lose the green function light on the OptiDrive and had no control over the truck, even when it was no further than 10 feet from me. The last time this happened, the truck rolled right past me at idle, no brakes, and hit the brick border around the flower bed at the end of the driveway. Luckily, there was no visible damage and everything seemed fine. After this loss of control occurs, sometimes I get the green function light back on its own without doing anything, sometimes after I shut off the truck and cycle the receiver power.
I didn't get any other warning indication from the OptiDrive other than the green light simply going off. The lowest I saw the receiver voltage get to was 5.8V. The voltage seemed to recover while the truck was shut down for refueling, jumping back up to 6.2V.
What I don't know is what voltage level puts me in the danger zone for the receiver battery, or if maybe it's because the battery is so old it is dropping out in "steps"? And lastly, is there any "age" consideration to take into account for the OptiDrive and other electronics?
I'm sure there's going to be some eye rolling due to this post, but I sure could use some suggestions from you pros out there regarding what to do to refurbish my old truck and ensure everything back to good safe working order. I'd be very thankful because I had a blast getting the truck running again, and my neighbor has taken an interest as well - he was blown away by the performance, so now I have a buddy to enjoy my REVO with - just gotta get past this weird problem. Thanks in advance!
