Pros:
1. Metal cowl
2. Very sturdy
3. Well balanced
4. Crazy cool sound!
Cons:
1. Maximum measured static thrust - 450g vs. 550 advertised (given that advertised thrust is static, isn't it), with all inlets and cheater hole (next to impeller) combined section 2 times the area of impeller (the fan was not air-starved)
2. Maybe it's just me, but I could not disassemble it. So much for full-serviceable :P

Overall - satisfactory, pretty good for the price. I was able to use existing 3S batteries and a 30A ASC - so no overhead expenses for me, when I bought it. Installed in 650g scratch-built Mirage2000 (yeah, over-engineered and therefore - overweight), when trimmed good gave about 40mph top speeds. I would give it 5 stars overall just for sound :) , but trying to be objective.

Es werden 550 Gramm Schub versprochen... Pustekuchen...

Mein Modell (Mini Kataka) wiegt flugfertig 450 Gramm, hier ist nicht mal annhernd so viel Schub vorhanden dass das Modell im Normalflug fliegen kann. Nicht mal mit einem krftigen Schwung beim Start. Dabei mssten 550 Gramm Schub ausreichen um das Flugzeug senkrecht nach oben zu befrdern.

Das ganze wurde an einem 3S 1400 mAh 40/80C SLS Akku und 60 A ESC versucht...

Da macht mein Fhn mehr Druck !!!

absolut NICHT empfehlenswert !!!

Runs very smooth and quiet.

Draws 20 amps on 3 cells. I am going to build an F117 faceted foamie for it.

Absolutely poor performance. Put it on a 450g plane and could not get it airborne. I only measured about 100g of thrust on a scale. The only good thing about this product is that it's pretty sturdy, but what use is that if you can't even get your plane off the ground.

I received the unit nicely packaged and it looked high end, that is all it had going for it. I put it in my little 50mm f22 wanting the fabled 550g of thrust but it was pulling more like 150-200g which i wasn't able to keep airborne. I recently bought a 4s and cut two giant cheeter holes in the plane. With this setup I am able to get about a 4:5 thrust to weight. My plane weighs about 370g. I dont know if i did something wrong using this motor, but this is the worst product i have bought here so far.

Plane is 470g. Using 30amp esc and 40-65c 3s battery I don't quite have 1:1 thrust?
Not sure how (up to) 550g of thrust was measured but I seriously doubt even with a massive cheater hole and thrust tube anyone will ever see 550g of thrust on a 3S battery. I would say I'm getting 450g of static thrust. Sounds good but there is a little vibration at low speed, smoothest at high speed. May require a little tweaking. I'm curious what other people think???
