great stuff - thanks for the reply. Explanation makes sense, given I need it in front of the firewall

i will need the back mounting kit which states it comes with

1) Back-Mount Prop Adapter - M6 x 24mm Prop Shaft
3) M2.5 screws for adapter
1) 5mm Retaining Collar, Steel
1) Prop Shaft Washer
1) Prop Shaft Nut
4) M3 Allen Head Bolt 12mm length
4) M3 Allen Head Bolt 20mm length
20) 1.95mm Hard-Ply Firewall Spacers (9.7mm OD, M3 ID)
20) 2.85mm Hard-Ply Firewall Spacers (9.7mm OD, M3 ID

You are right this is for the Sig 4 star 20 EP.

I'm glad you mentioned that Zs31014-14 motor as I'm in two minds whether that is a better one to go for. I'd like 400w of power and it seems like I will have to drive the 3009-20 hard to achieve that, especially as it is rated for 18-26A typical usage.

AUW of the 4 star 20 EP is around 38oz. What do you reckon? Your motor is obviously heavier and border line weight for the sig.

The Motrolfly is not available in the UK so not an option.

thanks David for the info and Scorpion suggestion. Guess I need to balance this power against flight times with a 2200 lipo.

Remembering the 3014 is 1 oz heavier.
If you can keep the weight down to 38 or preferably 36 oz. ESC, battery, wire length & lightweight covering, the 3009 is good. start off underpropped. Say 9x6 & check on watt meter + temps after flying. Move up prop size till you find the best balance. Often I haven't gone for the highest power because the trade off in torquing left on take off or duration weren't worth it. anything over 100 watts/lb INPUT in a high efficiency motor is good.

any idea how much weight the back mounting kit ads? Also I notice they sell

so does this mean the stock motors don't come with the hardened shafts?

Initial production run. Recent are fully hardened.

Hi everybody!

Im from multyrotor part of the forum and i have hexarotor with Zs2209-30 950 kV with 10x5 graupner e-prop on 3S. I cant find any test of this motor and this prop. I tryed to evaluate with scorpion calculator with APC E 10x5 since I guess both props are very similar. I enclosed the scorpioncalc results. Could smbdy look through since i'm not sure all inputs and results are OK ... I'm first time user of scorpioncalc

I would also very appriciate your experiance based thoughts about this pair of Zs2209-30 and 10 inch electro props.

Those are pretty small motors, id suggest its probably overpropped significantly, 67% efficiency is not fantastic . Try the 9x5 graupners

I have no experience with multirotors. I have some concerns about the results you post. It shows an efficiency of only 67% & the graph shows it well past the peak. In fixed wing applications I try to stay within 1 %age point of max efficiency. I hate all that electric energy going to heat. Part throttle does not change the amps or efficiency your motor sees, only the length of time it sees that current.

@ AAT,
Check out ecalc. Since that is not a multirotor motor I found it under the "prop calc" section of ecalc vs the multirotor section. Below are the results of your motor with a gr e prop 10 x 5 you can get results for most any combo you like.
NOTE the battery and model weights are not correct since i didn't know what they were.

Hi all!
Thanks for your help
I checked it with eCalc (good tool!) and it looks like Zs2209 motors are quite small ...
I will try 2212 size.
Thanks guys!

The ZS2209-30's on one of my quads typically run with 8" or 9" props on 3S. You might get away with 10" on 2S but you'll lose some efficiency. The 9" C/F props work well.. I occasionally switch to 8" for night flying, using the GAUI 'glow in the dark' props, with ultraviolet LEDs under them. Hyperion motors in general are conservatively rated.. I've pushed some of them pretty hard with no ill effects.

Play on Zs 4035 299Kv

I bought 2 of these in the big sell off. One has zero play on rocking the prop & one (NIB) has 1/8 - 3/16" measured at the tip of a 17" prop. The bell tilts with the rocking. The motor mounting & motor base do not. I am assuming it is a bearing issue, but don't know acceptable play.

If you can see the bell move, that is way too much. I would look for replacement bearings asap.

Anybody know for sure if any of the Scorpion bearings will replace those in a Hyperion Z4020-08 motor?

In particular this one?

There are no replacement bearings available from Aircraft World any more that I can see.

Thanks for the reply.
When I took the motor out I found the 5 black hex screws holding the false back to the back of the motor. They were loose. A little blue loctite & tighten was all that was needed. Checked my other motor which has been flown and they were VERY tight.
