    I would suggest the RET411

    I would suggest the RET411 by Vantec for this application. They work well at all speeds and reverse. I've used a number of them and am quite satisfied.

      Jeff,
      There are many good

      Jeff,
      There are many good ESC's out there, few have really good low speed priority. Subtech, Thor, Mtronicks, and Novak come to mind. All have excellent low speed. But I feel the best bar none(Just my opinion)is MCD. Model Control Devices. The Minicon is a very good choice. You did ask for the best, and few would argue this fact. Dave.

        The new ThorDesign SC-20 features

        The new ThorDesign SC-20 features 800 steps of resolution. No other SC comes even close to that sort of resolution for fine control all the way up and down the speed scale. I can count the number of times my propeller turns, easily, at low speed. This SC was designed for my personal use for installation in my new WWII Russian fleetboat. After using it I decided to have a production board made up and put it into production. It works great. Lyle has them in stock.

          I dunno that super high

          I dunno that super high resolution is that much of an issue with speed controllers.

          I tend to run around at full clip most of the time anyhow (I've got lead loaded fingers).

          What I do expect from a good ESC is a healthy current rating that isn't wildly exaggerated, a flexible voltage rating- at least 12 volt operation and preferably up to 24 volts, high rejection to interference, compact size etc.

          I don't need adjustable throttle settings, brakes or flashing lights. Neither do most other marine modellers.

          There used to be a chap in the UK who supplied excellent controllers, and they were inexpensive too.
          Unfortunately, I can't get them anymore, but as a substitute the Robbe Navy range of ESC's look excellent, although they do seem a little pricey.

            It's true. Matt sent me one and I'm very happy.

              Sorry. Resolution has EVERYTHING to

              Sorry. Resolution has EVERYTHING to do with SCs. It determines the jump in RPM between transmitter clicks. The more resolution, the finer control you have between clicks. Divide your speed band by 800 steps of resolution and see what you get for control VS the standard 80-140 steps. I know, I designed the #### thing.

              For those of you who prefer non scale speeds and like throwing rooster tails off of your scope shears then may I suggest traxxas speed controller or one of the R/C car SCs. This is a SC made for SCALE control. It can handle a FULL 20 amps at 12 volts with no trouble at all.

              For those who like scale speeds and superb, fine control for manuevering then the SC-20 is a great choice.

              We only ship to N. America.

                800 clicks and it'll probably end up mated up to a three pole speed 400, or something equally crude.

                All academic anyway- why are you only shipping to the States?

                  Will that SC-20 fit into

                  Will that SC-20 fit into Big Daves 2 in. conversion wtc. Also I have a chance to pickup a HiTec 6 channel radio,HRCJ 4340 radio,will that suit my needs.

                    The SC-20 is NOT a

                    The SC-20 is NOT a crude device. It is a very advanced marine speed control. I have it running Graupner speed 280s and it works fantastic. I have also run it on speed 600s at very high speeds and amperage draws in a 1/72nd SSN21. It barely gets warm at 20 amps. Most of the purchasers of the SC-20 have been the surface scale guys, Scale subs, and even a few tug boaters. It works great with the standard off the shelf motors.

                    The SC-20 might fit in the tight spaces of the mini WTC. I have not tried it in anything that small. It fits very easily in a WTC 3.00.

                    Shipping to Europe is more effort than it is worth for most items. The customs work is ridiculous and I simply choose not to mess with all of the stinking paper work that goes with each different country. I don't have time, and people are not willing to pay for my time to do it.

                      Matt,

                      I think something got lost

                      Matt,

                      I think something got lost in translation in my last post. I didn't say the SC-20 was crude. I was referring to the 3 and 5 pole motors most modellers use in their boats.

                      By choice I prefer using Pittman, Buehler, Maxon or motors from the car breaker yards for my models.

                      These motors are generally very high quality, and cheap if you purchase them surplus. The multipole armatures, mean they cog very well indeed at low speeds, much better than the ubiquitous mabuchi style of motors.

                      Regarding customs. I've never had any problems sending or receiving goods from/to the States. You just slap a ticket on the envelope stating mechandise and what it is, and send like normal.

                      Perhaps it's different over there?

                        Andy,

                        Ahhh! My mistake. Sorry about that.

                        The UK has very simple paper work and is not much trouble to fill out. France & Germany, however are a completely different animal. I sent a Flight III hull kit to a customer in France a couple of years ago and it was returned not once, not twice, but three times. The last time it was returned because French customs had added a form that was not even available in the States at the time. I ate over $150.00 in shipping. We have since had several items returned from Europe for various customs reasons. US Customs is absolutely worthless in trying to get help. They have become like the TSA in the airports. They are underworked and overmanned and the average IQ in Customs and TSA is about that of a pencil eraser. I got so sick of the running around and filling out the long green form, no wait or is it the blue form in triplicate. No wait, you have to have one of the French pink forms with a form 103, or is it the yellow short form....I gave up!

                          Standing on it's head. No problem. It will fit. I've had it in the 2 inch WTC from Big Dave. Go for it.

                          I was running mine last night in the Seawolf and after hearing Matt's comments I put it to test. At one click you could follow it with your finger. At 2 clicksthe same but a little and I mean a little faster and so on and and so forth.

                          I could inch along at a snail's pace. Scale as you want.

                          Although if I wanted to I could get those rooster tails I prefer the scale look. It's a great controller. Now I need to get another!

                          Matt,

                          OORAW!

                            Matt -

                            I have to ask.

                            Matt -

                            I have to ask. Have you ever considered the good old US postal system? In the 13 years I owned SubTech, I shipped thousands of packages (including a couple hundred kits) worldwide virtually hassle free. This includes virtually every country in Europe (I believe Lichtenstein and Monte Carlo are not on that list) as well as the Pacific Rim, Africa, and South America. One simple customs form (to, from, contents, value, do you want it back if not deliverable) for any country. Insurance is inexpensive as are the rates (UPS, Fedex, etc. can't even come close!)

                            Just a thought.

                              Sorry that we are drifting from speed controllers to postal systems but my experience (from the UK) has been very good.
                              I have received many shipments fro the US without problems and I have also recently been posting all over the world (New Zealand, Singapore etc) without any post or customs problems.

                              Hooray for free trade!
