The four threaded screws and screw holes that secure the two mounting brackets are absolutely useless on the unit that I purchased, they are very poorly machined and would not hold the motor housing in place. I have had to drill them out and put four small nuts and bolts in their place to make the unit secure (easier and quicker than sending the unit back, which might have the same problem!!)

La ventola EDF arrivata con l'adesivo Dr. Mad Thrust KV3000 e serial number ho subito guardato e testato la sua qualit, la ventola equilibrata alla perfezione nessuna vibrazione con bassi o alti giri il suono stupendo si sente solo la spinta dell'aria e lievemente il motore, i cavi del motore sono molto rigidi lunico difetto sono le rifiniture delle alette interne non sono sabbiate e nei bordi erano presenti sbavature di alluminio stata testata con una batteria a 3 celle 30c di scarica e regolatore Turnigy dlux 100A SBEC bellissima la consiglio fortemente

The fan EDF was likely with the adhesive Dr. Mad Thrust KV3000 serial number and I immediately looked at and tested its quality, the fan is balanced to perfection no vibration with low or high rpm the sound is gorgeous just feels the pressure of 'air and slightly the engine, the motor cables are very rigid the only flaw is the finish of the internal fins are sandblasted and edges were smears of aluminum has been tested with a 3 cell battery 30c discharge and regulator Dlux Turnigy 100A SBEC beautiful the council strongly

I purchased one of these to drop into the Sea Vixen which I built up from the kit purchased from here as well. I had to remove the intake lip from the EDF (which is held on with tape, easy to remove) and then cut some little notches in the wood mounts in the plane. Once that was done, she dropped right in and performs beautifully. Luckily it came very well balanced right out of the box and really makes the Sea Vixen move.
(using a 4000mah 4s 45c battery and 85amp ESC)

Cont from above review, This thing is a powerhouse! I tested the unit installed into my F22 and it really did sound like a real turbine at 85-90pcnt throttle and was smooth as a real turbine! Being my first EDF I'm a bit stupid!

However, I have built REAL turbines such as Allison 250's and PT6 turboprops. None of which hold and weight on a plastic compressor blades!

Well this is my EDF unit ever, this thing pulls almost 100 amps! I tried it out on 3s first to see about balance. To my disappointment it did have a vibration at 50 power. I disassembled the unit and I was impressed by the craftsmanship, had it not been for the vibration I would have said it was perfect! After removing the "spinner" I found that the fan blades where numbed. I put it on my balancer and the number 6 blade was heavy, all of the blades had holes underneath them. I removed a small amount of plastic and retested, It still had a slight vibration. I repeated and it felt slightly better. I than installed it into a F22 from here and put it on a 4s setup, after passing around 60pcnt throttle it smoothed out.

Grazie HK tutto perfetto...ventola ben bilanciata e il suono semplicemente stupendo.
purtroppo volevo un upgrade sul mio hk sport jet 70mm ma sono incappato in un banale errore: il rapporto peso/potenza rimasto invariato!
la ventola che ho tolto (motore freewing e girante a 5 pale) pesava 101g e il modello era ben bilanciato con 4S 2200 zippy compact (solo 3 min di autonomia) 250g!
gli ho messo questa ventola da pi di 400g in coda e davanti una batt 4S 4000mah 40C altri 400g (quasi 3 minuti di autonomia..io spingo quasi sempre al massimo per!).
il modello non pesa pi 1.1kg e spinge 1kg ma pesa 1.6kg e spinge 1.7!
insomma...nulla di speciale! peccato!
contro: io preferisco stare leggero sui modelli elettrici. aggiungere 500g senza aumentare la portata alare significa alzare la velocit di stallo e quindi rendere l'aereo pi instabile a basse velocit come per esempio in atterraggio!
pro: il suono per..quello spettacolare!

Thanks HK, everything is perfect!the fan is well balanced and the sound is simply amazing.
unfortunately I buy this unit to search to upgrade my hk 70mm sport jet but I stumbled upon a simple mistake: the weight / power ratio remained unchanged!
I removed the original fan unit (Freewing motor and impeller with 5 blades) weighed 101g and the model was well balanced with 4S 2200 zippy compact (only 3 mi
