Manda's (Amachan) RC Adventures

It wouldn’t be me if something didn’t horrendously wrong with anything expensive that I buy. So here we go. During one of the first I was distracted for a second and the car went off a bridge and into the pond at the local park. Luckily it was close to the edge, but it was still submerged more than a meter under water. I had to fish it out with a stick. I succeeded and most of the car was still working. Most of the components where waterproof after all, well apart from the receiver. They put the receiver in a (not-so) watertight box. So after I fished it out it was acting up, steering and throttling like mad. I turned it off and got it home. Sadly warranty was voided for any form of water damage.

So I needed a new receiver and I thought I’d get a new transmitter in the same process. I got the FlySky FS-GT3C with a receiver knowing that I can also get extra receivers quite easily. I am quite happy with this, it works well.

So everything would be well again I thought, so I went out a couple more times and then found out that the steering servo was acting up. I took it apart and found out that this waterproof servo was not so waterproof after all.

So I got into contact with Etronix, the manufacturer of the servo and told them what happened and asked if they knew of a way to fix it. They got back to me and said that as a good will gesture they were willing to replace it. That was great, unfortunately they didn’t have any in stock and would then be willing to send an alternative, a 6kg servo. Now the servo that was broken was a servo with 15kg pull strength, so that would have been a severe reduction in strength. I looked at their website and asked for a different one saying that I would pay the difference. So that’s how I got an Etronix ET2070, a 21kg servo for 5 pounds. It took a week or two to get here from the UK I then installed it and it worked great.

I then proceeded to add additional waterproofing to this servo using a silicone sealant for aquariums and sealed up the receiver box as well. So now on the mechanical and electrical front everything was fine again.
