want to change all servo's out to water proof ones, would be alright to use the #2075 for all of them?
I'm assuming you have reverse with the 2018s for throttle and reverse servos. I looked up the specs, and the 2075 is longer than the 2018, so it might not fit. What you can do is plasti dip them though. If you YouTube how to plasti dip a servo there's tons of videos showing how. It voids the warranty, but it's better than spending $150 on new servos.
2075 servos can be had on eBay for $20 a peice
They are all the same size. It should fit right in. 2075 is a very reliable servo. I have had fantastic luck with them. Have yet to burn out or break one.
