HobbyKing supplies a useful range of speed controllers, the TURNIGY DLUX ESC range (photos of some models shown below):
They are available in standard form (2S to 4S Li-Po) in 20A and 30A ratings.
They are available in higher Li-Po spec (2S to 6S Li-Po) in 40A, 55A, 70A, and 100A ratings.
All these 6 DLUX ESC models have S-BEC, and have data logging features (when used with the program box -there seems no facility to download the data to a PC).
In addition: These DLUX ESC'sare available in HV (high voltage) form ( -6S to 12S Li-Po) in 80A, 120A, and 160A ratings -and these 3 HV models have no BEC (opto) and no data logging feature.
They can all be programmed (and stored data accessed) using a program box which looks quite distinctive (see photo below)
I wonder: Do we know which (chinese) company actually makes this range of DLUX ESC's ...?
My own guess, at present, is that itmay be the well-known ZTW chinese ESC factory ... ? - http://en.ztwoem.com
-This is (partly) because the distinctive-looking (unique) program box is identical to the one supplied byGens Ace (i.e. AcePow), for all Gens Ace aircraft and car ESC's.
It is also very similar to the program box supplied by OK Hobbyfor their "Infinite" range of aircraft and car ESC's
And from previous information which is available from many people: see: http://www.rcgroups.com/forums/showthread.php?t=1333719
-It is certain that the ZTW factory makes the Gens Ace and OK Hobby "Infinite" range of ESC's.
Any ideas from the knowledgeable fraternity out there ...?
