“While I do agree that this unit provides a very nice sound, it does not provide enough thrust for my F22. I put in the 3800 kv motor hoping it would take care of that deficiency, but still took a little more than the entire runway to get it airborne. Maybe the F22 is a little heavier than the planes mentioned in previous reviews. I am going to try the 4000kv when they have it back in stock, and hope I don't burn it out. Wish me luck.”
“I picked up a couple of these to experiment with my Freewing F9F Panther and Mig-15. Both showed significant increased vertical performance and noticeable speed increase. Hand launching is now done with little effort and both planes fly off with authority right from the let-go. I used the stock Freewing 2627-4300kv motors that come with the planes and upgraded the ESCs to the Mantis 45amp 5a SBEC. These planes were fun, stock out of the box, now they are circus ponies and a total enjoyment to fly. The Mig-15 really shines with this upgrade and I can just imagine what the Freewing F-86 could do with this upgrade :-) {On a observation note: If I start to burn out the smaller motors more frequently, they're only $16.40 to replace and we'll see how long they will last} ;-)I picked up two of the 2836-4000kv power units and a couple of Mantis 65amp 5a SBECs to upgrade my Freewing A-10. (FYI Note: The 65amp ESCs barely fit in the A-10 body and the 85amp ESCs are just too big)I also picked up a third 2836-4000kv unit and 65amp ESC to upgrade an old Foamy DH-100 Dehavilland Vampire just for S&Gs. (I can't wait to see this old girl back in the air as she was among my dad's favorites)”
“Thought I'd try these on my A-10 which was good as was. Now there is power to spare. Actually fly's a bit fast for a A-10 but can fly great at 1/2 to 3/4 power. Vertical is no problem.”
“The last few reviewers said they're using their old 3500kv motors in this 12 blade fan, the ones from the 4s stinger and 4s F18. Just an FYI they won't last long, the old Freewing 3500kv edf motors are designed to handle around 35-40 Amps tops so when installed on this 12 blade fan the draw increases dramatically, to around 55 Amps. This far exceeds the capability of the stock ESC and of course the original 3500kv motor. Freewing has recently released a new 3300kv edf motor designed specifically for this fan and it's here on Motions site. It has an abundance of windings and slightly lower rpm's which make it perfect for the increase in amp draw. You will also notice an increase in thrust because the new motor has a lot more torque.Guys, an easy and cheap way to prolong the life of your equipment is to grab a simple watt-meter. It's the best investment you can pick up for this hobby. They have them here at MRC. Sorry if this came off too preachy lol.-tayze”
“I put this in my Freewing 4s F18. nothing but impressed! didn't even try the stock 5 blade, but oh well. Sounds as close to real as you can get with EDF.”
“Just put this in one of my planes or more like just yanked it out. I had less thrust than before, plane would not lift. With five blade 4000kv outstanding thrust, this 12 blade w 3500kv not so much, I change my opinion, back to five blades for me”
“I have had the freewing 4s setup and had replaced them in my planes with a hobbyking alloy 4000kv five blade fan. I saw the complete 3500kv unit was out of stock but then realized i had two of these motors from the units i had pulled from my other planes! I just assembled one of these with the 3500kv motors i had laying around and i am impressed. I was afraid it was going to come out of my hand as i was afraid to grip it tightly with my hand as it did not have the forward lip attached. It has great thrust but i have not set it up on a scale to measure but am not concerned as it sounds so different i cant wait to put it in a pl@ne. The sound difference ishuge . No instructions but a piece of cake. I am buying another, it is a lightweight powerhouse and the high pitch scream is gone,replaced with a whooshing sound i am sure will sound like a jet in flight. I am guessing at least a thousand grams of thrust”
