Kyosho nitro tracker from the 90s - help!

[Kratonwatch]

Every few years I’ll fire up my nitro tracker from the 90s and this is the first time I’ve had issue. The servos are geeking out and I’m not sure why. I’m thinking the BEC is bad. Any ideas?

It's acting like the radio isn't on. I remember my old AM stuff doing that. Is the transmitter turned on, and have the matching crystal?

Make sure to have good AA batteries (not any dead or weak ones). There isn't an BEC as the batteries are hooked directly to the receiver.

I figured it is a BEC because it says it right on the unit. My batteries are all fresh and the tx is the one for the rx. There were corroded batteries in the battery tray, but I cleaned it up and put fresh ones in.

I didn't see that. Maybe something is wrong with it? Maybe check where the corrosion was to make sure there's a good contact.
I don't remember my old AM receiver saying that. Mine was 4AA (6v) in holder and 6v to servos.

Maybe try unplugging one of the servos to see if one of them has an issue.

I always thought those receivers that had a BEC were intended for something with higher voltage like the NiCd 6cell 7.2volts battery packs of that era. Or the 6 AA battery holders. I don't know much about them. I never used a multi-meter to check what voltages were going out compared to going in.

I got it all worked out finally but my steering is reversed! More tinker time I guess

Glad you got it going. If there is a CH1 switch that'll be the one to fix the reversed steering.
(Or marked a FUN 1 switch )

Out of curiosity what is the make of the Radio gear? (Tx/Rx)

I looked all over for a switch. On the remote and on the receiver and found nothing

I’m not sure who makes the receiver that’s pictured above. I think It comes up as futaba when i searched.

There should be two small switches on top by the power switch. Steering should be the closest to the On/Off switch.

This should help. It's a manual: JR Python 2CH

10 year old me (which is when I got this rig) thanks you endlessly.
