Designed by Robert, who is technical director of Phoenix. This beautiful jet in scale 1/7.5 is going to bring you the adrenalin, high speed thrilling flights with true jet sound thanks to the new CS XRP 14 fan blades with motor Cyclone Power 6S 1550kv, setup provided by TurbinesRc (http://www.turbines-rc.com/fr/turbin...1550kv-6s.html).
The progress of the assembly of the kit Phoenix is high: the works to be performed are routine: it takes longer time to put all kit details that assembly the structure!
The wings are assembly in two pieces for easy transport to the field.

The kit Sea Hawk Phoenix includes a series of scale details in plastic that must be applied to the fuselage: front inlet air, antennas, gear and whell compartments. The details must be cut and applied with cyano glue.

It's not a bloody Sea Hawk for heavens sake!
It's simply a BAE Hawk. This seems to be a hang-over from an earlier thread.
THIS is a Hawker Sea Hawk...

Hello!
the model is a Bea Hawk but Phoenix sells it with this exact wording:

"Amazing RC Sea Hawk 90mm EDF"...

The inlet ducting is in epoxy as the tube thrust.
Very well made and that inlet allow to arrive directly the air on the fan. The weight is:
cone thrust 90g
inlet ducting 130g.
I might try to not install the intake to test the performance of the fan. This option would save 150g... I'll think about

For nose gear first must glue the plastic cover compartment and make holes for passage of the rod for the retraction and push/pull of steering.
I forgot: in my website you can find all my review:

nice work Sandro!
you may be interested to hear my impression of this model as i already logged 15 flights in the last 2 weeks.
there us a CG problem. you must do some modifications to get it right.
i took out the pilot figures and mounted the reciver batterry at the tail.

the main landing gear is too much forward, if you put the tail to the ground it stays down. i think i will have to replace the struts with wire ones that will be bent to the rear.
as it is now the landing is jumpy no matter what i do.

flight performance is exelent and with some modifications it will be my best jet
i use Wemotec evo, a HET 58-1970 , and 6s 5000 25c battery

Hello Omri
I saw that jn the manual does not shows the position of the batteries and for these I contacted Phoenix to ask where they thought to put them for have an exact centering CG.
I will let you know. Meanwhile, thanks for the information
