RE: Which (chinese) facctories make various brands of ESC ..?
POINTS TO MAKE:
1. These hugely differing prices, for identical 100A HV ESC's, with identical features, made in the same factory, is striking.
2. The SJ PROPO (original factory brand) 100A HV unit is $127 ( -from Duanesplanes).
-We can pay up to 240% more than this ($299), for the identical ESC, if we buy the same re-branded and identical Robbe 100A HV ESC from ConradUK.
3. Clearly, the SJ PROPO-branded 100A HV unit is cheapest; We can pay another $80 for the identical O.S. 100A HV ESC (-and it does not even have a fan ...-it is otherwise identical to the SJ PROPO 100A HV ESC); -And we can pay a still further$70 if we buy the identical Robbe 100A HV ESC, from Midland Helicopters in the UK..
4. What does this tell us? If we buy an original factory brand unit, labelled as SJ PROPO, or a "budget" brand such as MegaPower, -then we get the 100A HV ESC for the cheapest price.
But: As soon as we buy an O.S.-branded ESC, or a Robbe-branded ESC -even though they are identical units, made in the same SJ factory, with identical features -the only difference is that they havebeen re-branded as "O.S." or "Robbe" with a stick-on label -then we have to pay 80% -or up to 240% -more, for the very same identical ESC, made side-by-side in the same factory.
5. And why do O.S. and Robbe cost 80%-or up to 240%-morethan the original branded identical ESC ...?
-The only possible reason that we are paying this extra amount for O.S.-branded and Robbe-branded units -sincethey are identical 100A HV ESC's in all respects -is just so we can have the O.S. or Robbe label stuck on the outside of the ESC..?
-There appears to beno other logical reason ... ?
