HI! Guys,

Had anyone try the Typhoon 2W-20 700volt brashless motor? Saw it on the Warbird wedsite I think is a new product(I guess). Which ESC and batterys will run better on the motor anyone?

Hi X-spec

I fly the HET EDF 2W in a HET FA-18. Actually I use a Hacker Master 40, 4S Kokam 3200mAh and the WeMoTec MiniFan 480. The current is 32-35A (450-500W). Motor temperature max 62°C. Now I'm building a West Wings Hunter and there I will try the 2W together with the Tsunami 30. This will give a very cheap combination.

HI! Norbert ,

The 2W you 're mention was it the Typhoon 2W-20 from Warbird site? Here 's the wedsite from Warbirds.com for more better idea http://www.warbirds-rc.com/Merchant2...egory_Code=NEW

I think the main difference between the 2W and 2w-20 is the ability to have more voltage pushed through it. The overall length is also 5mm longer i know mark at http://www.rtmodels.com has had one at 1000W so far and is testing on 16 cell, 18 cell and 20 cell FAUP's and a 6S setup and will be testing more lipos as soon as he gets them i can't verify the 1000w but i was there lst night when it was pushing 890W you have to remember the 2w-20 has only been here in the states a few weeks so it may take a little more time to get real world results from different ppl who are now jst getting them. he also stocks the 2w-20 and most of the others http://www.rtmodels.com/HET-RC%20Brushless%20Motors.htm right now i'm happy with the standard 2w BTW he did have a 65Amp ESC not sure what if any smaller ESC would be ok or not??

Hi X-spec

Sorry. I wrote it wrong. I don't use the 2W. I fly with the 3W to have the low currents (32-35A) at 4S Lipo.

Just got mine last week. Bench tested it with 4s2p 20c lipos/Wemo minifan/CC45. Got 575watts @ 37 amps or so. Will try this combo in NIB T-33. Not sure whether my test stand was working right but showed 62 oz of thrust with inlet lip on and no ducting.

ePower

I think thats impossible. 62 oz = 1,75kg. On 4S I would expect a static thrust of maximum 1 kg = 35 oz. How have you measured the thrust?

I measured the thrust with a pivoting test stand that pushes a rod on top of a digital kitchen scale. I tried a Mega 16/25/2/ 4s2p/ CC45 on the Kyosho fan(no spinner) and got 393 watts @ 32 amps with 43 oz. thrust(?). I'm going to try the hanging scale as soon as I get the fuse mods done on the T-33 and install the Minifan setup. I tried the Kyosho(same Mega setup) on a foam vertical stand on top of the kitchen scale with a 3s2p(200 watts) and got 20 oz. of thrust without a thrust tube or inlet lip so as soon as I get the hanging scale setup I'll let you know. It would be nice if someone else had some test data to share for comparison. All I know is the thrust dramatically increased with the 2W-20/4s2p setup and by the TLAR rules it should shove the T-33 around pretty good. I saw a video of a Sniper with the 2w-20 in it, and it was down right scary! Hey, for 65 bucks you can't go wrong. With the 4s2p lipos you've got a hot setup for your EDF jet. And you're not pushing the motor to the max, so it should hold up well in the long run. Or you could go ballistic and use a 5s setup and really soil your pants! In the absence of info on this new motor, I just do what I always do, stop thinking/talking about it and do it and see what comes up. Keep up the R&D and have a blast! Power to the people!

X-spec,

HET-RC makes two different models of motors... the EDF 2W is rated as a 400 watt motor, turns about 4600rpm per volt and can be used with 3S2P Lipo packs. The EDF 2W-20 is as was mentioned a bit longer and heavier motor, which allows it to disipate more heat. Those are some of the reasons it is rated around 700 watts, it turns around 3000rpm per volt and can handle a 4S2P Lipo pack.

You are going to get much more power out of the larger motor, but you will need more expensive Lipo packs, a better ESC and possibly a BEC for your receiver. I can tell you though that 700 watts of power is OMG awesome when you are holding it! I just bench tested the new Warbirds R/C - HETRC F-20 Tigershark using the HET EDF 2W-20 Motor, a Hacker Master 77-O ESC and a 4S1P Kokam 3200 Lipo pack; with timing set to the standard of 18 degrees on a charged but unpeaked pack, I got 696 watts!!! I am going to up the timing two degrees to see if I can keep it above the 700 watt range( a feature I like on the Hacker ESC's, adjustable timing one degree at a time).

Check out the reading...I am going to peak the packs just to see what kind of initial burst I will get and I will try it again.





I would recommend the 2W motor with any good 3S Lipo pack and ESC that can handle 40-45 amps. The Hyperion 50 amp, Castle Phoenix 60 and Hacker Master 70B are all good candidates. For the 2W-20 motor, a Hyperion 50 or 80 amp ESC, Castle Phoenix 60 or 80 ESC and the Hacker Master 70-O ESC are all good choices, but will require that you use a BEC (Battery Eliminator Circuit) like the Ultimate BEC to power your receiver. I would also use a 4S Lipo pack such as the Kokam 3200's or a Thunder Power, Tanic or Polyquest 4S Lipo pack rated at 60 amps continuous for some safety margin. I hope this helps and let me know if you have any other questions.

Cya,

Carl,

I'm new to this stuff and you seem like the guy with all the answers
Why do you need a BEC with the 2W-20???

I'm planning on getting a sniper and I'm debating on which motor to use. I want power, but don't want to end up with very expensive bateries that only last for 3 minutes flights.
With the 2W-20 and a 3700mah lipo, what flying time should I be getting?


Thanks for your help

Jack,
I would guess around 8 min. or so. I get 10 on a 4s4400.
As for the Bec, some Esc's aren't rated for 4s power, so you have to run a seperate Bec to handle the increased voltages.

I'm running the Tigershark that Carl mentioned too. WeMo 480 and 2w20. Castle Creations 60, Ultimate Bec, PQ 4s4400
Here's how mine clocks out. Way fast enough for me.

Sounds like I'm using the wrong ESC. Tried a CC45/PQ 4s 4400 and I was only pulling about 593watts @ 40 amps. Have to go get a 60 amp ESC and try it out. Thanks for the input. I'd like to get the power system right before I glue the fuse halves on my T-33. Once the glue sets, its major surgery to change the fan/motor out.

I've done some measurements with the HET Typhoon 2W20 with (not the newest) Kokam 4S3200, Tsumnami 30 (with increased heat sink) in a WeMoTec Minifan. In the appended diagram you will see:

Peak: 650W, 42A, 1175g ( 41.5 ounce)
Continues (after about 1 minute): 500W, 37A, 1075g (30 ounce)

Glacier,

Thanks. I'm going to use a CC80, which is supposed to have BEC capabilities up to 4s.

On your F20, do you use one battery pack, or do you use two separate packs?

I'm getting a sniper, but haven't seen one in person and I don't know about space limitations... I guess I'll check out the plane first before buying the battery.

Thx
Jack

I was wondering if anybody is running the EDF 2W at anything obver the rated 38A. I am planning on using one in a Vasa65 with 3s LiPo and am getting a calculated 43-44 Amps. Is that too high, or can the motor handle the extra "punch"?
Whats the max. Amps you are getting, and also what prop is used alternatively? (I'll be flying it in a MPX MicroJet for a while before putting it in the Vasa65).

Thanks

Can someone tell me watt the watts system is on Kontronic 480-42. Is it comparable to the HET 2w-20 700 watt motor that everyone wants and can't find.

CTulanko

jetsetf18,

While they are indeed comparable motors, they are also two very different motors. The Kontronik 480-42 will produce 550-600 watts of power, depending on battery capacity and C rating, ESC, fan, thrust tube diameter, etc... but it is made for a 3S 11.1v Lipo maximum for power. The 2W20 however requires a 4S 14.8v Lipo and turns a lower RPM/v, which is compensated by the larger Lipo. The Kontronik has the advantage of not requiring a BEC where most ESC's running 4S or higher like those neede to power the 2W20 motor require an additional U-BEC to supply power to the receiver. A more comparable motor to the 2W20 would be the Kontronik 480-33 and it is also a 4S motor and produces similar power when compared to the 2W20. Quality wise though, the Kontronik wins...hands down.

Mine on a 4S 2200 20C pack pulled 54 amps and 700 watts. If I put two packs together to get a higher C rating I can pull 58 amps and 825 watts. Im using the 6904 fan in my Phase 3 F16. With a pack that didnt have enough juice I hit 99mph. I was hitting the low voltage cutoff so I have some 30C packs I need to try. I wrecked the jet 3 days ago so Im not sure of my top speed yet. Probably around 115.
