Announcng the BI-3600 inrunner for 70mm fan

After many emails asking where is the 70mm Wicked motor I have a nice solution for those who want to to fly 70mm models but do not high amp high watts setups but more of a sport setup. The best way to describe this motor is it is a little hotter than a 2W-20. In the HET 6904 fan you will get about 100-120 more watts and more rpm as well. Here is some test data for you.

BI-3600 HET 6904 Fan
4S3000 20C lipo: 41,500 rpm, 810 watts, 58.18 amps, 13.92 volts
4S4700 25C lipo: 44,000 rpm, 950 watts, 63.88 amps, 14.87 volts
OD: 28mm
Length: 47mm
Shaft: 1/8" (3.175mm)
Weight: 134 grams (as seen in photo)
KV: 3600

For comparison:
2W20 HET 6904 Fan
4S3000 20C lipo: 39,600 rpm, 700 watts, 49.30 amps, 14.20 volts
4S4700 25C lipo: 41,600 rpm, 836 watts, 55.8 amps, 14.98 volts

So a nice way to get a little more rpm and power over a 2W-20 setup without the need for high amp and high cost ESCs. This motor is intended for
4S use only.

Bi 3600

Well let me be the first to pop in here give you my experience with this motor.
my Son (corsair nut) got two of these from Don to test. C/N has been gone out of town working so the testing defaulted to me i only had one air frame that i trusted enough to do the testing with ....my good ole F-4D Sky Ray (scratch built ,depron foam)i have been testing a JS1400 /HET 6004 fan in it with a XPS 5000 4s batt. awsome performance over the orignal set up of a HET 2w /HET 6904 fan, it did about 600 watts on a 3700 3s batt and was a fair performer for its size and weight. the JS combo is a good set up but requires a big batt ,big esc ect ect . so i decided i would set up the "blue ice"colored motor with a 60amp pentium esc that i bought from Don.i have not tried to tune the motor esc combo just pluged it in and flew it . The motor ran very smooth and i was impressed with the numbers over 850 watts and about 60 amps on a XPS 3200 30c 4s batt. Wow thats pretty good so i proceed to fly the plane. now i had just flown it several weekends in a row with the JS set and it was really fun with all that power on tap.the BI 3600/HET 6904 /XPS 3200 batt .....i was easy on it at frist to make sure it would'nt smoke....so i used a batt that was'nt as powerful as th XPS ,next flight i put the XPS 3200 in and i was taken back by the performance..i really could'nt tell much of any difference in speed or vertical .what i did notice was man it is turning really sharp and seems to be "floating along"....after my normal routine i came in for a landing ...what a kite,i taxied back and ck the temp it was only about 10 degrees above ambient . thats when i started calling it the "blue ice" motor.
So my feeling is this.....the 2w20 is a great motor ..the big blocks JS1400 ,Hoffman ,ARC motors have there place ....but we have seen guys stuffing these in foamies and trying to fly them on too small a batt. this motor gave me close to the same performance as a "big" motor but with as much as 12 to 14 ounces less weight. i think the 3200 ish batt is the perfect size ...but i think it would do well on a 2500 ish pack in a small foamy such as our beloved HP F-16 .i have flown it about 8 times now as of this writing and i really like it ...the temps out here are rising daily and the motor cont. to perform flawlessly and so is the pentium 60 esc . i hope to get some vid up soon of the plane flying...also im fixing up my HP F-16 to use a wemotec 480 fan and the other BI 3600 motor and flying it on the 2350 rihno 4s batt to see how that combo works ...any way it's a great motor for any 70mm foamy that is out there ...cheaper esc required,cheaper batts required ...less weight perfect for your favoite foamy,give one a try you wont be disappointed.

Thanks for the feedback Air Sally! I've been talking with Don about this motor and I think it would be a great motor for my HET Super Sniper I'm going to build with the HET 6904 fan and a 4s lipo.

Just saw this motor on Dons website. Looks like a good candidate for my GWS J-10. Im running it on 3s around 450~500 watts right now and it needs just a little more oomph. 600watts on 3s would be about right for a nice light moderate power setup. And wouldnt take much to pack a 4s in there if the speed bug bites.

Thanks for the info AS.

i tried 3s but i only got 450 watts ,,,but it was a old batt that has'nt been used in a while ...Don designed this motor for 4s and the bigger the batt the more it puts out ..but i think most foam edf will perform nicely on a 2500 to 3200 4S Batt 20-30c. i like the 3200 xps batt for the best weight and power. Ideal motor for a foam plane ....it fills the gap between a 2w20 and the larger JS1400 /Hoffman /Arc 1 turn(these require a larger batt and esc.)ck my 33" sky ray thread so you can see the size of plane it is.i need to lern how to post a link

I think i miss read your post the first time. I thought you were saying this motor put out 600watts on 3s, but i see you were referring to the HET 2W-20. My mistake.

i just ran up the BI-3600 in a wemotec 480 with a 2350 rihno 4s 25c batt and it peak at about 730 watts and 50amps ...it settled in @ 690 and 49 amps...not to bad for the 2300 batt time to fit it into the trusty old, beat up HP F-16 .i only had a 45amp esc ....poor thing it's going to get hammered

Flew my HP F-16 with the BI-3600 /wemotec 480 ...it flew well but the poor little 40 amp esc said that is enough ...it cut the power so i flew at reduced settings and landed ..there is a vid up on you tube of the Sky Ray ...go to "youtube Scott Metze" channel...you cant see much but the sound is good .
