Canopy and pilot look nice in the Hawk, but I wanted something a bit more realistic without going overboard

I looked in my "pilots drawer" to see if I could find something suitable, and found a few inexpensive parkzone pilots that could do the trick ... They seem more or less to be the right size, maybe a tad too large but ... oh well.

Some very simple detailing ...


From the Hawk size (102cm wingspan or scale 1:9.75) one needs - by simple scaling - a pilot whose helmet is ~27mm in diameter, close to the one that comes with it, or almost exactly the Parkzone size one.

It seems to me that the RA Hawk helmet is only slightly larger than say a regular motorcycle helmet.

The original Red Arrows BAe Hawks have a really glossy & clean look :

Which is of course not easy to replicate on a $160 foam model where the surface finish is good, but not perfect.

The surface finish out of the box is a nice matte red, I put on two coats of Johnson's Future water-based acrylic to give it a bit more shine

Maybe but probably not ... unless it gets a good sanding as well

Having a second inexpensive spare canopy available gives you the option of playing around with various setups

Bought two new HK zippy compact 60c batteries for the Hawk and the F-16 ... flew very nicely with the new batts ... finally burned up the ARC motor

Motor was ~3 years old I think, so it did a good service, very light & a lot of power.

I think one of the windings shorted, maybe too much heat.

Motor quit right after takeoff, went around 360 degrees with no power and had a perfect landing on the strip w/o flaps

Dug deep in my 70mm fan box and found two Freewing 70mm 12bl shrouds, they seem stronger (fiber reinforced) than that plastic CS fan.

Also found two CS 70mm 12bl fans, I think they are older V2 (vs newer V3).

But I did like the CS fan better than the Freewing one, the latter has a bizarre undercambered airfoil

Installed the HK Mad Thrust 2970 motor with four bolts at the front and support at the back as well, all secured with ge silicone ii.

New fan assembled with HK Mad Thrust motor, CS 12-bl rotor in Freewing shroud.

Checked for fan balanced on my test stand, then mounted in the Hawk

Re-checked the CG since the new fan & 2970 MT motor is heavier (motor 196g vs 87g for the old arc)

Very comprehensive update, Herb! Will be interesting to see how your "melting pot" fan works out. Please advise what power it draws, and if you see a performance gain.
