My Fly Fly BAe Hawk build and scale mod thread.
I got started at last on my Hawk. I bought this kit from Phoenix Racing (RCG handle) Here in the UK, thanks Scott!
I decided it should be covered in tissue and Poly C, so got going on that first.
After rubbing the fuse parts down with a sanding block (cork in my case) with fine glasspaper, the part was cleaned using a sponge and water.
Using natural light,the dents/divots were identified and lightweight filler used to cover them.
After curing, the filler is sanded and blended, then the Silkspan and WBPU (Poly C is better as it has a hardening agent mixed in)
Then the excess Silkspan was removed using a scalpel blade,another thin coat of Poly was then brushed over.
When this has set, I will sand`out any wrinkles, then add another thin coat.
I'm doing this to all of the fuse parts whilst still seperate, to join later.
I'm using Spring Air 602's with the supplied oleos in the kit.
I want to add a lot of detail to this model, so am hoping to achieve the best scale finish I can.
It will be using an RAF display scheme, mostly black.
The power system will be a Schuebeler DS-51 with a Hacker B50 and 6S lipos with a Hacker 77 Opto ESC.
I'll add flaps to the wing too, and proper gear doors and other details.
Anyone want to chime in here with suggestions, please do!
I need to cover the second rear fuse half and then the nose parts,so a way to go yet..

I have now completed the fuse covering, just leaves the wings/tail parts, not much to show with photos yet, but once all surfaces are covered,I'll install gear etc.
How far are you into your build?
|Mar 04, 2008, 12:14 PM|
I joined the fuse halves and wings so far. I have a few projects ahead of it and waiting on the motor to show up to see if it will be a good fit (1800 kv Ammo inrunner).
I am still debating on glassing or not.

Tail parts covered, I'll post pics when I have something interesting to look at..
I haven't attempted a dry fit with my fan unit yet,but if it doesn't fit, some tools I have here say it will!
Get all the boring covering job done first, then on to the fun parts.
Still not decided on radio equipment yet..

Ok, all the boring bits done (sans wing covering)
I trial fitted my Schubi fan,it is longer than the kit fan,I just need to file down a foam circular ridge to get it in, no biggie really.
I'm looking at methods of beefing up the airframe where possible due to the expected surfiet of extra power!
If you look at the indented panel lines, they were difficult to fill with the Silkspan on the first pass, but I found that using a sharp scalpel blade and slitting down, then using a bit more P C fils them in nicely, just a little tedious to do, but it will be worth it.
Post covering the skin surfaces feel incredibly strong and less likely to dent over the bare foam finish.
Here are today's pics:-

Glad you're watching Scott! It will take a while due to the skin finishing process more than anything,also looking at at adding flaps.Probably don't need them, but it aint scale without them!
I'm wondering what the RAF are dreaming up for their new scheme for the slo 2008 display machine..I'll see what I can find.
Of course, the cockpit interior won't be overlooked either...I have my work cut out it seems.
Gear doors would be nice too, we'll see.
Am doing a few hours more on it today
|Mar 07, 2008, 12:45 PM|
Just the wing left to cover now-I have sanded/filled sanded, coated...just goes on.
Anyway, here's where I'm at,one more sanding and I can join the sides after fitting the servo leads and modifying the motor mount.
I'll get there sooner or later!!
I have to work on my dining table, no room anywhere else

Hi Matt. I have a friend whose nephew has been chosen as this years hawk solo demo pilot - I am sure he may be able to find the chosen color scheme ?
|Mar 08, 2008, 10:19 AM|
I'm thinking of using these cels (Enerland)
A123's would be nice, but I'd need to buy lots of cellls as they are nominally 2300 mah per cell, meaning I would have to buy 12 cells ( for a 6s 5600 pack) and the voltage is poorer, so really no choice but lipo's!

I had these on my HD,RAF pilot garb, should help a lot when I carve my pilot.
Also a useful panel too.
I hope to get some more time building this tomorrow.

Schubi fan install
Had to cut some foam away with a razor saw (about 1/2") from the fuse lower hatch area to allow my longer shrouded fan to fit, kept the cut offs and glued them to the hatch.
In order to get the afterbody fairing of the fan in, I had to cut some foam away ahead of the warm air exit under the fuse.
Bit of a pain, but the only way to get the DS-51 in..
Skyhobbies, or anyone, can you tell me where you installed your ESC.
I can't close the fuse up until I have this info, so any help is appreciated.
Here's my fan fit.
My plan is to refit the cut foam parts back one happy that everything works ok, the cover with silkspan before painting. If I ever need to access the fan again, I'll simply cut the reglued parts out.
