Agreed for the most part, though I think a person cannot get any simpler than a plug and play electronic switch. The Strv has zero servos in it. Mike

But I deliberately left out the various "RC Switch" options because: (a) there are a lot of different technologies used (drivers, FETs, relays, etc) that require some electronics background to understand the subtle differences (b) most of the ones that provide functionality equivalent to a MAG Speed Control (servo with two switches wired as a mechanical H-bridge) are much more expensive then a servo and two switches (c) servo and switches are really, really simple, making them really easy to install and trouble-shoot in the field. I'm a big believer that everyone should start with the truly simple solution, before looking for the "better" solution. That way, they'll have a working benchmark to judge alternatives against. And, after they gain lots of experience (aka. failures) with the "better" solutions, they'll know just how sweet the simple solution really was. Bear in mind, "simple" doesn't mean "inferior" either. I have servos that are over 20 years old that have gone to hell and back (sunk too many times in warships, jolted hard in tanks with no suspensions, etc) and they are still working just fine. 20A micro-switches are made for literally millions of cycles and cost $1 or less from surplus stores. There's certainly enough room in any tank so that volume isn't an issue. It takes only a few minutes to swap out switches and/or servos if something does go wrong. That said, I have multiple prototype boards that implement MAG Speed Controls using relays and FETs to replace servo/switch solutions. Definitely more expensive, slightly better reliability and slightly more compact. The production versions will become my "go to" RC part for elevate, rotate and trigger control, but it's taken many iterations over the years to zero in on an approach that can service all the different ways that those systems can be operated.
