CoolerByTheLake, you are right! I did a quick test here and guess what, the blades has broke in thousand pieces, che*t ! Too fragile this CS 12 blade EDF... I did the static balancing before running the EDF for hours and get the maximum balancing point... well, not enough. I have one spare EDF, let's try again...

The super habu has become a big one jet, 90mm EDF are off the table, did order a new 120mm EDF, 4 blades, 5000w motor...

Sorry to hear that. There is an entire thread on RCGroups Electric Ducted Fan Jet Talk on this fan, which contains a number of tips to keeping this fan together. If you haven't already, you should check it out.

That CS fan is just not meant for high power, they just expolde. I have the JetFan 90 for my build. Mine will be smaller than yours, so I think 3000W+ (Het 700-68-1680KV 8s, could also use there 1500KV) will be more than enough. If the weight comes out close to what I am shooting for, that's over 300/W lb.

Just glad you found out before doing damage, or totaling the plane.

I would say that the JetFan 90 with the right motor would fly your Habu very nicely.

OK, i think 90mm are good for 3000g to 4000g jets, this big Habu reaches 5500g ....so, i need a bigger EDF.

humbertomelo You may change your mind after seeing this video. His plane weighs 16lb or 7257g. You be the judge!

My F-86F will weigh about 15lb/6800g and I will be using the JF90.

CoolerByTheLake, It seems a very good setup. I have one here very similar in numbers:
CS 5 blades 90mm EDF, 140a and 3100 watts at Max power, 8s Lipo 40c,

D_FAST, It looks like a great EDF!


Let's try on this Saturday... :-)

Better for fan to blow on ground than in air

humbertomelo Does the 2200g include ALL the flying surfaces, too?

CoolerByTheLake,

2200g was a weight estimative, the final weights are:

Lipos: 1380g for 12s and 920g for 8s
Fuselage with electronics: 4120g
Total: 5500g

humbertomelo thanks for taking the time to answer my questions. It has been very helpfull. I am still in the planning stages, but I did notice that your Habu and
my project have the same Length vs WS ratio, 6/5. Mine will be 1/6th smaller at 60"Length, WS 50". By using the various numbers you have provided, I am failry confident I can come up with an AUW of around 9lb/4082g with an estimated thrust of 4.2-4.3Kg.

Now all I need is lots of practice in your foam bending technics. I am sure there will be many mistakes!!!

You have taken the next step in the evolution of building with foam.

Can't wait to see the maiden video.

This fan produces 9.9 lbs static on the bench, on 9s. I didn't get the thrust on 10s, but she flies on 10s now. My Habu 32 weighs approx 8.5 lbs.
It's faster than P-20 power in this airframe.
The motor is a HET 700-68-1680 with a CC ICE2 120HV


The video is on 4000mAH, but 5000's will be in there shortly.
This setup should fly many 90mm birds nicely, at a nice little weight savings. Something to consider.

Mark,
On bending the depron......
If you can find a good place to lay your heat gun (i use an old shirt to keep it still on my work surface) and use 2 hands to work the foam passing it back and forth in front of the heat you will have good luck...Its a little harder to hold the gun andfoam to work it into the bend you desire...
Just try not to leave the hot air in one place for long or it will ruin the piece..
Another cool trick is if you get the bend to tight you just add heat again and the foam will open right back up on its own if no force is beiing applied to any of the sides...
Its very cool when you get a piece bent perfect and it fits right in the spot you are trying to cover...
Take care all..............Chris
