I don't understand... Most other companies give you a suggested prop range and max current/ power that the motor can take. Hyperion have gone many steps ahead of this... So what if the data is 100 percent up to date with newer G3's. Use the given data as a guideline. Most motors are rated conservatively anyway.

  1. I have always supported Dave's efforts (for over 7 years in fact) and this is not a complaint about him just a reminder that he promised to do something in September that would take about a week to complete. Brian from AC World confirmed this was happening at the time.
  2. The "note" you refer to does not say it is "old" data. It says - All data below (except new 4025-16, pg. 3) was collected with previous generation LiPo, ESC, and Optical Tachometer. In some cases the batteries delivered relatively low voltage output (blue highlight). Use of new G3 Lipo packs may result in higher current flows and corresponding increase in rpm. Tests with Hyperion G3 LiPo, Atlas ESC, and Emeter II Phase Tachometer will be posted by June 1 2009.
  3. The issue is not about "old" data and new generation Lipo's it is about WRONG data and that is what Dave highlighted and undertook to correct. There is a big difference between data that may be understated because of old generation batteries and incorrect data that was due to flawed testing methods. Dave has PM'd me on some data and was very helpful. I also highlighted some inconsistencies in the data and Dave acknowledged this.

Again, this was a reminder to Dave to post the new data and in doing so would ensure his customers were making their purchase decisions based on correct data. If time is against him - remove the link to the page - easy!

Well let's just hope it's all updated soon.

We are "almost" on time. Had a delay in receiving some parts, but have got them now and are in full production swing. The line manager says we should have a good number of each type done between Jan 15~21, so expect them to hit dealers around Feb 1st.

Thanks!

David

Dave - Awesome work on all the new motors and esc. Ive tried diff combos on my sniper xl of the turnigy and emaxx stuff. After having tried 2 times too many. I finally ditched it and went to ZS3025-10 and a 4S 70A lbec Atlas. Wow just wow. Lighter to boot

You can mail the Emax motors to me. I have some Emax motors and they compare very well to expensive motors. Power is good and efficiency is tops.

Just for fun I looked at my Spreadsheet for thrust data with a 6x4 APC E to try to match 19020rpm/726g... of course I don't have exactly that rpm, but I have one above and one below:

18780rpm = 740g
19410rpm = 837g

Either I'm too high (~780g @ 19020rpm) or your calc (726g) is a bit low... or, we are both wrong!

Hi Phil
SC is giving lower thrust (on your data)
18780 rpm 708 gf
19410 rpm 756 gf
Maybe the good average is higher (between)
Are your figures averaged on several testings ?
(I have not those data on my present old xls from you)

On your data .xls I just remark (on Komodo 2413 + APC 6x4E)
17670 rpm Kiwi 558 gf SC 627 gf (SC is higher)
17400 rpm Kiwi 651 gf SC 608 gf (SC is lower)
17370 rpm Kiwi 540 gf SC 606 gf (SC is higher)
Humour ON
As my results are from a routine, my standard deviation = 0 better than your data standard deviation !!
Humour OFF
Anyway, I will accept to update the old file .xls I have from you (v11 -1 : 4401 lines).
Thanks

Louis

Hahahah good thing I sold em already. Nothing wrong with emax motors for the small stuff. But trust me, when it comes to the bigger motors, Hyperion ZS motors are way more efficient. Too have the same numbers these bad boys are putting out, the emaxx motors are almost twice as heavy. When you put those on a 3d plane, your AUW goes out the window.
