Wanted to share my experience in hopes of saving someone else the massive waste of time and money, and in the slim case management from 3DR reads this and is aware of the misleading, and possibly fraudulent activities goes on within their company.
5 weeks ago I placed my first order with 3Drobotics. I received
-1 broken motor
-2 broken ESC's
I suspected I did not have SimonK flashed ESC's, but was assured "there is no possibility of this, we only sell simonk flashed ESC's". OK.
I ordered 2 additional motors & 3 ESC's to replace my brand-new-broken-equipment. When I receive this, 2 of the ESC's say "simonk" on the sticker (and one of two new motors is broken). I call 3DR to find out - tech support then says my other, original 4 ESC's are NOT simonk, and that would send me 4 more that are 100%, for sure, simonk flashed firmware.
4 ESC's arrive without the Simonk sticker. I call support again, actually speak to a technician and make them listen to the codes over and over, and they assure me the 4 new ESC's NOT labeled with "simonk" are actually simonk, and the 2 I have that are labeled "simonk" need to be sent back to them.
-been lied to by multiple 3DRobotics employees on the phone (sales & tech support) as to what kind of ESC's I have in attempts to make me go away. Maybe sales does not know how to identify an ESC.. but technical support? there is no excuse.
-experienced a crash, at my expense, due to mismatched ESC's cutting off while the others kept running.
-received 3 distinct hardware versions of supposedly the same exact item. 1 had simonk, 2 others did not. I say different hardware because they have different length wiring, are different physical dimensions and have different board layouts.
-paid for shipping 4x on mistakes made by 3dr. and of course, each time prepaid for all items & had to wait at least 2 days for an order, with ALL ITEMS IN STOCK, to ship. 3DR 'Next day' = 3Day
If you have ordered an ESC from 3drobotics in the last 5 weeks, chances are you do not have a SimonK loaded ESC. Also, you may have mismatched hardware running the same firmware or maytech firmware with different settings (ie: low voltage cutoff). I would HIGHLY suggest checking to see what you actually have and avoid a crash. Besides being DUPED by 3Drobotics.
You are lucky!!!!!!!! I have had no answer, no proposal... only "I am sorry to hear about the problem. I will forward the information to technical support. Someone will assist you soon. ..."
Someone....!!!!.... Hope soon!!
Here you can find the original and complete manuals in PDF format directly from the manufacturer Maytech: http://www.diydrones.com/forum/topics/please-help-in-setting-up-3dr...
Can you elaborate on your statement that setting 16KHz makes a substantial difference?
1) What difference did you get?
2) How did you measure that?
P.S. I also set:
- 6 to high
- 11 to reduce power
According to the manual 8Hz is for normal low pole motors like inrunners , and 16 for outrunners . After i changed it i noticed a much better throttle response , higher top end, and the motor ran noticeably quieter. More efficient i guess.
I have been having problems with a ESC just twitching the ESC, which would make me suspect the ESC timing is wrong for the motor... Ir bad or the wrong firmware... Could I have this same problem with the new DIY y6 that I got this week?
