The quality as expected BUT HOBBYKING makes people confused, as they this this product "programmable via Tx, Programming card or pc USB port." but to program by USB port yo must have the programming Card....I use it in mini eco expert racing boats and it still good, I have it 2 years and still the bestFlew it with a 3s battery on a bixler a while a ago for a few times. After i put it in storage for a year i decided to test it as i usually do just to keep the stuff fresh. After connecting everything i revved it up on a testbench and i noticed instantaneously that it got very hot while applying only 20-30pcnt power on 3s. I pulled the power out and let it cool for a minute. After that i tried again and it bursted in smoke! If i had it in a plane it would have burned up the whole thing. Luckily it was on my test bench. Worked awsome as long as it lasted until it decided to kill itself in smoke. Nothing i would use on expensive systems. Only for some cheep epo stuff without expensive equipment.These things are awesome. The governor issue with hthe others needs to be flashed with blheli using arduino uno. I use these on my bigger rigs with high poles and low kv motors w/o heat. ONLY issue is the amount of noise on the gps frequency in some cases knocking out gps signal (bad bec) just disable bec. These are hobbywing platinum esc.good quality. Comes with motor connectors. Have to get a programming box to change parameters if you chose.Mont sur un HK450, aucun problme, la configuration avec la radio est un peu particulire et je ne m'y tenterai pas, j'ai utilis le cble USB avec le programme Hobbywing et aucun problme. Fonctionne trs bien avec un Turnigy Typhoon 2218.This ESC is pretty great. The very soft start is 8 secs so you won't have a problem with that, and it barely gets warm during usage. I highly recommend NOT buying any programming card, because programming with tx might be a little scary at first but it's really really easy and fast. The usb programmer might be useful for fw updates, but I'm happy with its current state already.Great ESC. I haven't had any problems programming this using the Turnigy Multifunction LCD Program Box. Works great every time. Haven't had it get hot and I have given it a fair bit of stick. All around great ESC!No consegui ativar o modo soft start, mesmo com o carto de programao. Minha compra foi frustrada, j que o principal motivo do pedido foi ter uma acelerao inicial lenta. J tentei fazer pelo rdio Turnigy e tambm no tive sucesso. Acho que o produto est com algum problema de srie. No gostei da compra. Estou arrependido.No consegui ativar o modo soft start, mesmo com o carto de programao.
