So far so good. I had to do some research to figure out how to wire the ESC up to the motor (others informed me that there are indicators on the ESC for A, B and C, but mine had nothing). For future reference and to make it a little easier for others with the same issue: Blue = A, Yellow = B, Orange = C. I've upgraded the dongle and ESC to the latest blinky firmware and am using the default settings still. I'm running this ESC with a SchuurSpeed 4300kv motor in a Tekno SCT410 and a Savox 1258TG servo without any problems thus far. The car made it through its first race day dead last (of the cars that made it to the finish anyway), but that's because I'm a rookie driver and not the fault of my equipment.

I bought my first LT4 several months ago and it has been flawless. I run it in an OFNA TS4 and I can't see the value in buying a $200 or more esc to do what I do, casual racing at track and bashing. There are other cheaper escs direct from overseas but it is nice to deal with someone in the USA. Next on my list of things to get are BH batteries. Thanks Stan.

I have always been a hardcore castle guy . I have 3 associated sc10s an sc10b and a b4.1 worlds car. I wanted to run a sensored set up in my b4 and I have seen nothing but great reviews for the lt4 so I figured why not . I did not want to pay castle price for a mamba that's for sure . I have to tell you I have ran a castle 1406 4600kv unsensored and a turnigy 9.5 sensored motors with it and it doesn't even get warm . I have been very impressed with the lt4 performance . I just orders a back up esc on Saturday and it was in my mailbox on Monday . Unbelievable ! Keep up the great customer service and great products and you will defiantly have a long term customer here . The only suggestion I have is maybe in the future make up some combo motor esc kits . Seems to be the way a lot of your younger racers like to go .

What can I say, this ESC is nothing less than spectacular. It handles any 540/550 size motor I throw at it easily. It has never gotten hot and performs as good or better than expected each and every time. This is actually my second one and am thinking of buying a third one. I recommend this ESC for anyone needing a speed controller for any 1/10th scale vehicle running 2 or 3s.

I run this esc in a 2wd SC10 with a 3300kv reedy motor. I have not been in the RC world long, but I am amazed at how easy this esc is to operate, and take apart and clean. Stan is absolutely amazing when it come to customer service. One of the best experiences I have had with a product.

The Speed Control is just what I expected by when I open the boxes of the two purchased there was no USB Flash Programmer in either box Not sure if that was supposed to be included, but I think so. Have watched and talked to others that run these and they are a quality product. +++++++++++++++++Thanks! You ordered using the discount code which states it is for those who already have the USB link, hence the discount you used. Contact me to get one...Stan++++++++

Fantastic ESC for my B44.2 -- buttery smooth and great braking. Easy to set up and solid. Every bit as good as my Novak Havoc Pro ESC but more programmable and cheaper. One piece of advice is to turn off the reverse if you are doing mid-air attitude corrections -- if you don't you may think you are getting brown outs as the ESC pauses to protect itself. Also, it works great with a Savox 1257. Have the 80a in my 2wd buggy and just ordered my third for my sons.

I use the LT4 120A in a Durango DESC410R with an old ICON 550 2-Pole 5000kv motor. It pushes the 6.5 pound truck on 2s all day without breaking a sweat. I have never had a glitch, brownout, or thermal in all of my sessions of racing. I am slowly converting my fleet of vehicles to all use this since it is small enough for just about any 1/10 scale application.
