    One thing I forgot to mention is that the wires that come with the esc's are 12 gauge, the pics I posted are with 10 gauge I soldered on. The new 4-8s esc solder points for the motor side are very close to the fets so watch the soldering iron temp so not to pop one if you decide to change wires.

        I just used one with a 10XL on 6s lipo worked great out of the wrapper, no troubles with a JR pistol radio, just plugged it in and it worked great. This set up is in an OSE offshore Raider 25".

          You ran that power in the little mono? How did it go?

            Steven, you are not going to like the set up. It is my Father's boat. He cut a 1" wide 1.5 * delta pad on the bottom, and is attempting a sub surface drive system. So a strut angle at 7.5*(submerged), wire drive, 10XL on 6s 3800Mah,a X432 detongued/ back cut. I gotta say I have never seen a boat leap out of the water like it did, power on demand. Unfortunately, with a sub drive system and angle at 7.5*, the thrust is at the motor and lifts the bow like crazy so we could not relocate the batteries up towards the motor because we ran out of velcro, about 40% CG. This thing is going to be a rocket, if it will stay in the water.Thanks for your great customer service, I will keep you posted and get some video.

                The one with the Ammo is fine. The one with the SV27 motor ( in a 32" cat with a 445 prop) was working great until the other week.
                As I plugged the batteries in the spark seemed a little bigger than usual and the ESC would not arm. No noises or beeps whatsoever. The BEC was still working because I still had power to the receiver & rudder servo. I tried unplugging & plugging a few times but she no go. I changed the receiver but still no luck.
                If anyone can advise on what the problem might be and if it's fixable it would be appreciated.
                Although this is outside the realm of this thread I still have to ask... Is there a simple way to reduce that splash across the plugs as you connect the batteries to the ESC?
                Cheers.

                Great site to use to help calculate resistor value to arrest the discharge current of the capacitors.

                  Not sure why it dosen't arm, but will it reprogram as per instructions? Other than that might be fried,toasted or otherwise.

                    I just got one wet, it fried but the BEC still worked. Finally after taking the shrink wrap off, i could tell it was fried.

                      Thanks for that info Jetbill Very usefull

                      Won't rearm can't even get a beep out of it. But the steering servo & reciever still work from its BEC.
                      I don't think anything on the main boards fried. It was working fine on the previous run. Just wouldn't work when I plugged it in for the next run. It just seemed to me to be a slightly bigger splash when I plugged it in.
                      Maybe it's like Aussie crawl said ...a faulty programming chip on the PC board.
                      My other one is still working fine & I've ordered another one. At $60.00 for a 200A ESC I think it can be considered a throw away item. A pity though.
                      Thanks for the input guys.

                      See the danger. THEN DO IT ANYWAY!!!

                        with a lot of esc,s if you blow acouple of fets they can be replaced and everything works fine but with the himodel ones for some reason it wont work after checking a few of these i have blown up and repaired none have ever worked properly again. only thing i can put it down to is the control chip or the program it runs.
                        as paul said tho its a rather cheap speedie
                        cheers scott

                          I had the 3-7s fully coated with epoxy 270 with water cooling and also used the Dimension Engineering lipo safe. After 1 min. use the ESC fried on 90Amps. You must me lucky with these ones.

                            Gotta say, tried one in my Titan 29 with the 10XL on 6S (5000mah 20C Zippys) and same deal after a minute of 40+ mph fried too. Not sure really why, I added some water cooling to the top (fin side), but she smoked from one of the boards on the other side. Too big of prop? Used a GrimRacer 44x66. Not sure if I should order another... If it is just under cooled, then might reconsider another $70 ESC.

                              FeCalc estimates your setup will use 167 amps and 3400 watts for a Feigao 540 10XL using a 4466 prop. It would have been ok with a KB45 10XL for that setup. It would use 80 amps 1700 watts.

                              Were the lipos 5000 20c 6s2p?

                                Just some advice to avoid smoking stuff...

                                Start with small props, take temp readings a after a few passes and move up in prop size if everything stays cool.
                                Get an amp meter (watts-up meter or better an Eagletree logger) if you really want to know whats going on in your boat, they are great tools.
