- After seeing my F-22 flight with this setup and generating over 300 km an hour via GPS. I've had several requests to make a video illustrating the thrust of the motor on the trust stand.That said, the results are as follows:
On 9s thrust was 5.5kg at 120amps
On 10s thrust was 6.4kg at 141 amps watts 6100
Hands down you're not going to find anything on the market that delivers this kind of power at this price point with this versatility and performance. I'm not a fanboy of FMS norm am I paid by them but you got to give credit where credit's due. Well done FMS well done indeed.
Hope the information helps you guys with your projects. Houstan out!
Great info as always, also great suggestion on the mango and amaretto
Good info man!! I have heard really good things about these packs as well! A friend ordered them on accident! He loves them!!
Damn... wish I would have seen this video before I bought a schubeler fan..
Really interested to see a comparison of FW 8s metal 90mm to the FMS 8s metal 90mm back to back 8s and 9s ?
I have same setup in my f22. I was using custom timing at 7 for 40 flights with no issues. I watched a video and changed the timing to low 1 and 2 minutes into the flight power failed and I deadsticked. I guess im saying I would not run low timiing with castle using this motor fan combo.
Pls were can i shop for fms motors and how to.get them
Also these motors have internal cooling fans... with higher rpm the fans will blow faster... much cooler them...
Thanks for this information. Any data regarding longevity on 9 or 10s. How did it go in the plane?
Every single plane that I put it in the performance was fantastic. I like the extra weight in the plane because it doesn't get pushed around as much in the wind both in the f-22, f18, Yak 130 and FMS super scorpion. Cheers
@@ghoustanable do you think fan and motors can handle full power continuously on 9 or 10s without breaking or burning? I'm very tempted to try this but want to make sure reliability will be reasonable too...
@@acw400 I've run them hard with absolutely no issues on 9s and 10s. The motors have never burnt up nor have I had any rotor failure other than sucking something into the rotors off the runway. What I definitely can't tell you is that 12s is definitely a no-go... you will destroy the motor and the rotor. That said, the answer to your next question is yes I did try it on 12s on my thrust stand can't remember what the numbers were but it was insane and it only lasted for about 30 seconds before the rotor completely destroyed the entire unit. Curiosity got the best of me so I tried it but I tried it in a safe way. Cheers
@@ghoustanable Thank you so much for all this information. This is very helpful.
To reach 300 km/h which battery did you use?
Did I hear you say that the motor gets hotter on 8S than 9S & 10S? Do you know why?
👍
How do you power your FrSky dual supply Rx? Use an additional BEC? Powered from Flight packs?
It depends on the plane. If I'm running high voltage servos, I use 2s lipo directly to the receiver. If it's like a freewing plane that needs 5.5 V, then I use a BEC.
Hi, does the motor supports 10s voltage ? I have the viper 90mm on 8s setup with the same edf unit + motor
Yes, it does.
Hi mate. I’m looking at buying this unit for 8s. But after watching this, and the little extra weight from going 8-10s it’s probably worth going 10s. How have you got on with it? Still working? Thanks Tom.
Everything's been working fine however I think 9s is the sweet spot with this motor when you consider overall weight, amp draw and performance. On 9s you can get away with a castle 120 for 10s you're going to require at least the castle 160
It will be lighter than the stock 8s version from Freewing. My 8s is even heavier then when I set mine up for 12s.
Quick question. I have this exact set up for my Freewing F22. Is there anything specific I may need when extending the battery leads from the esc? Or can I just extend the wires to reach my battery? Also, is the castle 20amp bec sufficient for the Freewing F22 or is there something I need to add? Thank you and sorry for the book. New to this side of building custom.
20 amp bec is more than sufficient for the F-22. Regarding extending the battery leads, just make sure that you match the gauge of wire for the extension. Also, I'd recommend soldering the extension wires together as opposed to putting in bullet connectors to make the extension connection. I did that with my F-22, and it ended up costing me my plane due to a partially disconnected bullet connector causing arcing and eventual power loss in flight. See the link below below of that crash. Cheers and good luck 👍. ruclips.net/video/2IEh14r_ZeA/видео.html
Ran mine on 12s and it ran like a champ. Definitely more punch to it. Still isn't getting hot at all. Same set up. Castle 160amp esc, Castle 20amp bec, with the FMS 4075-1500kv 90mm edf. Not sure if you have tried a bench test 12s yet but I must say that FMS motor is a beast.
@Jason Willoughby that's fantastic. I'm definitely going to be trying that once I have batteries that can fit. Thanks for the heads up on this. Send me a link if you've got a video of the flight. Cheers 🍻
@@ghoustanable I'll have to get a video this weekend for you then. Only have a certain 2 batteries that fit to run it 12s. They are premium HRB 6s 5200 100c. They are short and stubby. The graphine 6s 5000 100c won't fit in there good enough and maintain cg.
Can jet fan handle this? If I were to get the 1500kv and run it on 10s do you have an idea? Currently I’m running the 1680 on 8s and was thinking to upgrade for more power and speed
Yes Jetfan can handle it. The hardest that I've pushed it is 1400 kV HET motor with Jetfan v3 on 12 's and it worked just fine. The link below is for my 10s flight with the exact same setup. ruclips.net/video/GduRucOdeOI/видео.html
@@ghoustanable hey brotha one more question how much flight time do you get on 10s 5,000mah?
@@octane2099 if you fly hard 2 and 1/2 minutes with throttle management 3 and 1/2 minutes . Obviously this also depends on the condition of your battery and the weight. For the first flight keep it to two and a half minutes check your batteries and then adjust accordingly as far as time goes in subsequent flights.
@@ghoustanable thanks for always replying and helping
I have an engine like this and the recommendation is batteries up to 8s, are you using up to 12s. Does it not burn the engine or force it too much?
Maximum you can run this on is 10s. That said, I did do 3 test runs on 12s & on the last run up, it exploded. Personal if you ask me. The sweet spot for this motor is 9s if you want to keep the amp draw below 150amps.
@@ghoustanable which battery you hit 300km/h and the Esc is Ubec or Opto?
@@maicondp yowoo 4000mah 100c graphene paired with Castle creation 160 ESC and BEC. ruclips.net/video/ID0l-2xlOC4/видео.html
So if you run the motor on the highest setting how long does it take to drain the both battery packs? Say if they are fully charged.
Thanks.
Two and a half to three minutes on 5000mah
Which connectors do you use because the gauge wire on the motor is smaller than the esc
XT90
@@ghoustanable yeah I was talking about the esc connection to the motor what size banana connector you use
@mr.maneuver287 I run Castle creation esc, so 6.5mm bullets is what's needed with that gauge of wire from the ESC. The gauge of the wire on the motor is usually smaller than the wire on the esc, which is pretty common.
@@ghoustanable ok perfect and is there specific settings i should program the esc for.. and I do want the reverse thrust as well
@mr.maneuver287 you need the USB Castle creation dongle to go into the programming section in the software. The tab you're looking for is auxiliary. Select the drop-down for reverse thrust, and you're done. Note that you'll also need to run the auxiliary wire. I believe it's a white wire to a separate channel on your receiver to get it to work. Then, just assign that channel to a separate switch on your radio to get it to work. Cheers
you are making my brain explote!.... how much fligh time do you think you can get with an 6000mah on 9s?... what will you say to put a 3300mah on 9s? i heard you can flight with 12s on 3300 easy cause the consumption is lower on 12s
6000Mah 3.5 min. Regarding 3300 pack on 9s too short a flight for me. This edf cant handle 12s. I tried it and the fan exploded. very dangerous situation!
@@ghoustanable thanks a lot for the answer and the info !!
@@ghoustanable Hello, after about 8 flights with the fan on 10s I`ve noticed a significant power loss ... I was aware of not heating the edge and the esc... might I damage the edge? Is it fixable?
@danielalessandrini2299 that's strange. I'm not really sure. it depends on the damage to the ESC. That's said I've never had any problems with this setup with over 200 flights on five different Jets the setup has been rock solid.
@@ghoustanable yes very strange... i bought 2 of them and both had the same problem... and the esc are working fine, 12s 150a
So this esc is reverse thrust capable??
Yes I use Castle creation Phoenix Edge High Voltage ESC.
Update: ran this exact set up and everything was great until the 10th flight. The fan blew itself apart at max throttle during take off. The motor might be able to handle 10s but the fan has potential to fail.
@bryanho6830 sorry to hear about that. I've been running it on over five different 90 mm jets for 2 years with over 100 flights with no fans failing.
Who knows, maybe the new batches are not as good. I bought another one and will try again. The performance is amazing at this price point so I gotta try again..wish me luck @ghoustanable
hi, what's the thrust when using 8s?
Installed into my F4 phantom it's 3.9-4kg. Installed into my F22 it's 4-4.1kg. In my T45 it's 3.7kg. All 8s.
@@M4rkmcc21 thanks for the reply! I just realize thrust are also depends on the aircraft design.
@afxdz evo yeh I found thrust is lost on twin exhaust jets. Also if thr exhaust outlet diamter is too large like in the rafale there's a loss. Can 3D print a smaller outlet tho. Also the T45 Exhaust tube is obstructed with the Air brake servos. I found opening my cheater intakes on my Sirius gained 150g of thrust
@@M4rkmcc21 good information thank you vm
