Hobby King Fire Phoenix - VERTIGO Rebel 90mm EDF Trainer

(For full disclosure: I am the original designer of the VERTIGO Rebel)

I know as of this writing, there are several of the Hobby King Fire Phoenix's out there.
http://www.hobbyking.com/hobbyking/s...00mm_ARF_.html
It turns out this is a great trainer for the authentic more sophisticated, all Epoxy composite VERTIGO Rebel.

Guys are coming up with great ideas on how to set these up.
What I am doing here is building my Fire Phoenix more like the original VERTIGO Rebel 127mm sport jet seen here.
http://airshowrc.com/rebel_vertigo.html

To keep things simple, I think I will stay with the fixed vertical stabs instead of the full flying rudders on the Rebel.
There is no design into the wings for the leading edge slats like the Rebel has.
I am going to make the full flying elevators like the Rebel has.
Others have opted to fix the horizontal stabs and cut in elevators.

As most of you know who are following the Fire Phoenix, BRuff has been having way too much fun with his.
At the field it has been called the "Baby Rebel" and "Little Richard"
More to come!
Thanks, Richard

Fire Phoenix Hobby King's Cheap copy of the VERTIGO Rebel (4 min 10 sec)


UPDATE 08/03/2013: Until now, one has ever seen a Fire Phoenix and VERTIGO Rebel together before.
Below are the comparisons.
The Rebel is all epoxy composite with vacuum bagged wings.
The Fire Phoenix is polyester with wood wings.

First thing I did was install the wings.
Wing root.
You can see the 6mm CF guide tubes on either side
with spar and a short drywall screw in the middle.

Got the electric retracts and struts installed.
1) Turnigy Full Metal Servoless Retracts w/Steerable Nose Assembly (3mm pin)
2) 7075 Alloy Shock Absorbing Strut Set

I used a dremel to open the width of the landing gear rails to accept the electric retracts.
Be sure to test the operation of the electric gear before installing, just in case...
Then installed the struts after grinding the flat spots on the landing gear wires.

One thing Bob pointed out that I thought was pretty important.
The bottom of the fuse at the intakes need some reinforcing.
A piece of plywood works wonderfully.

Yes, I agree, that would be better to go all the way back.
I used what I had at the time...

Next is the mounting of the 90mm EDF and motor.
Because of the larger battery, I positioned
The EDF further aft than the normal location.
The red cups are from WalMart, 4 for $1.
I had to extent the EDF mounting tabs with plywood.
It appears they made the opening for a 114mm EDF.
Attached the Mylar thrust tube.

90mm Haoye EDF
Hyperion HS3026-1900kv

Next is the Ailerons to install.
Instead of the included CA hinges,
I opted for some stouter regular hinges.
Best if 15 minute epoxy is used.
CA glue cures too fast.

Hinging the full flying horizontal stabilizers.
I had to open up the slots for the hinges.

Aileron controls.
Servos, pushrods and aileron horns.
I used the HobbyKing 939MG Metal Gear Servo 2.5kg/ 12.5g/ 0.14sec
I used my own aluminum horns.

Sweet build. I'm looking for another bird for 120mm edf fan or maybe a 18pound turbine.

I like the 90 but why 8 x the cost for the 120mm bird?

What the market needs are some cheap 120mm jets to go with our newer lower cost 120mm edfs

Well, the Rebel was two years of R&D, Best technology and materials.
Still half the cost of some other 120mm jets.
The Rebel was originally deigned for 3D jet flying fitting a P-60 turbine.
Notice all the flying surfaces, Huge ailerons, full flying elevators and rudders.
Leading edge slats.
I'm not sure there is a 120mm EDF that will power a 3D flight yet.
The HK Fire Phoenix is just a cheap copy that flies very well.
This is why it makes a great trainer for those who will step up to the Rebel.

Do you have a thrust vectoring nossle for it?

Also I'm not sure there the same but your control horns look a lot like the ones that came with the 30cc GeeBee R3 powered by DLE55, Mine uses 2 of those horns with no issues but one flyer only used one horn and it broke on his 2nd flight

Can 5000mah 12 fit in the 120mm jet? Will you be doing a build on it?

Also what do the Leading edge slats do for you?

Thanks sweet jet
