BEC：N / A（OPTO）
I've just bought my second of these & at this "new" price I will very likely buy several more. The only potentially negative buying consideration might be its bulk & weight... However, for projects such as large ARTF warbird EP conversions when the nose commonly requires anything up to a kilo of lead or iron to get COG then this is far more productive cargo & its huge finned heatsink benefits from optimum cooling behind the prop! ...... It's got short 8 AWG motor tails fitted with gold, 8mm female connectors & is supplied with a pack of 3 of mating 8mm male connectors for the motor tails. The power input leads are duplicated - comprising pairs of tinned 10AWG tails (presumably, considered more flexible in all respects than single, thicker gauge leads). There's also the usual, thin spark suppression, pre-connect lead (positive) also just tinned........ I've got my original one of these paired with a Turnigy Rotomax 80cc on 12S & it runs nicely cool.The first Turnigy 250 that I bought (form Hobby King) came with capacitors that were loosely attached to the escape at the solder joint. As I wasn't familiar with this unit, I assumed that this was the normal situation. The capacitors eventually broke off with a few insertions and removals of the esc from my plane. I orderered a second esc and on this one the capacitors were firmly attached to the unit and could not be moved. IF YOUR ESCAPE HAS CAPACITORS THAT ARE NOT FIRMLY ATTACHED TO THE ESC, SEND IT BACK IMMEDIATELY AS IT IS DEFECTIVE. This is the first problem I've had with Turnigy products.This is a heavy-duty brick of a beast of an ESC - great for adding "useful" weight to the nose of a large EP warbird conversions in place of inert, iron or lead C of G ballast...... It's got short 8 AWG motor tails fitted with gold, 8mm female connectors & is supplied with a pack of 3 of mating 8mm male connectors for fitting to motor tails. Rather than also using 8 AWG wire for the power input leads, the manufacturer has opted for pairs of 10AWG tails for both ve & -ve, all un-terminated - tinned only. There's also the usual, thin spark suppression, pre-connect lead ( ve) also just tinned........ I've paired this ESC with a Turnigy Rotomax 80cc for installation in a 12 kilo warbird on 12S & initial tests suggest that they are very well matched & ESC will run nicely cool.Have two of them and both works perfeckt with there 100CC on 12s 16000mAh Multistarr.
Weight of the Modells 14kg and 18kg, Propellers are 26x12 and 28x10. I love them and want more..........Fitted in my 2.6m sukhoi with rotomax 100cc very good conbination massive power. Motor control very very goodexcelent esc... buddy www(dot)hobbyking(dot)com/buddy(dot)asp?code=7B7B667B-F45A-4330-81D5-EB35BDA72938This ESC is similar looking but larger then the famous brand one It seems to work well Its light weight for its size Huge amount of cooling surface. best to just watch the video and see what it does. Look for the you tube link in the discussions here
