The Rockwell T2 Buckeye

by Nigel Hawes  - Summer 1997

 

Nigel Hawes designed and built this very attractive Rockwell T2 Buckeye which has graced the slopes at several PSS meetings in recent months.  Here Nigel describes the path he took in producing this eye-catching model.

It's time to crawl out of the woodwork (no pun intended) regarding the construction and design (?) of my Rockwell T2 Buckeye, which I believe has graced (or should that be DIS-graced?) the pages of this magazine in the not too distant past.

I have had many kind comments about the end product, indeed it has won 'Best Jet' during its short life, but I must admit that underneath all the glitzy lipstick and curls lurks a 'rough old country botch' for which I should perhaps obtain a dog license.  I can think of several excuses for this but the one I'm sticking to is that I had only seven weeks to do it before the Northumberland PSS event last April, and it had to be ready.  Any which way!  Fortunately, I found the strength to overcome the embarrassment of photographing it during construction, so the shots should emphasise just what you can get away with  when you're in a hurry and flat broke!

Opting for a larger model this time (so I'd stand more chance of SEEING it crash!) the Buckeye was ideal as it had all the right proportions, together with a colourscheme liable to glow in the dark.  So, having found a nice article in 'Airplane' magazine and settling for 1/7th-ish scale, battle commenced.

 

Dad turned me a couple of round front formers on his wood lathe.  These were joined with 1/2" square balsa, nose block added and we had a front end!  The rest of the fuselage formers were loosely outlined from blue foam, on the basis that they could be 'cut down' when I found that everything else didn't fit.

The massive fin and dorsal gusset were a framework of 1/2" balsa, with a split rudder needed for the cruciform tail arrangement.  The tailplane was a built up structure from 3/8" sheet cut into strips.

The two partial structures were adjusted to mate with each other, but first all the gaps in the fuselage structure were filled with blue foam blocks which were sanded to shape.

When joined up it dawned on me that this was one big bird and room in my signal box workshop was going to be diminished rapidly!  Everything in sight was then sheeted in 1/16" balsa.

 

The Eppler 205 wing cores were cut out by Neil McHardy and myself out of white foam and veneered, shortly afterwards I sat on one panel and damaged it - I'll let YOU guess whether I made another or fixed that one up!!  Having cut the wing seat at the correct incidence and organised the wing bolt mounting system, an 'engine unit' was clagged together using white foam, balsa, veneer and loads of filler.  This unit screws on underneath, giving the Buckeye its characteristic chunky depth.  After making a cockpit interior with pilots, a canopy for a Fouga Magister (which I'd bought from Ray Jones at Woodvale in 1984!!) was modified to fit and the entire airframe was covered in Solartex.  Radio installation was simplicity, the flaps and ailerons use different lengths of torque rods running parallel.

The finish is white cellulose primer and Day-Glo orange which was sprayed on in a car booth and once detail such as panel lines, decals (all hand cut from vinyl) and other graffiti had been added, the whole thing was lacquered using 2-pack car lacquer.  The black bits are car tyre wall black which was finally added at 2am on the morning of the event and whilst still tacky for the test flight, at least it didn't stick to the fingers enough to prevent the launch ... and it was dry when I landed it!! 

Although I was well briefed for the flight (i.e. - I had a spare pair of underpants) it was docile and predictable and I look forward to exploring its potential at this years events.  It looked a bit bare without the wing tanks (which are blue foam covered in Solarfilm and then tyre wall blacked and resemble elephant suppositories) but performance and trim appear unaltered with them fitted.  All in all a pleasant conclusion to seven weeks panic!!

So next time you vote at an event for a beautifully finished model, depicting the original in almost every aspect,.....BEWARE!!......it might hide a variety of evils, especially if its one of mine!  But who cares, so long as it looks good, flies well, performs reliably and realistically with a reasonable measure of strength for harsh arrivals?  It's not HOW you do it, it's AS LONG AS YOU DO IT!

So go do it!!
