Getting back to it after about 30 years........
After the Barton
B.A.S.H. (our local aerodrome) here in Manchester, I saw my very first
model jet engine. I saw an engine spooling up to
about 150 thousand rpm, and I want one! I went out, and bought an Easy Pigeon, with
Futaba 6X, to re-acquaint myself with new technologies in the modeling field.
Later I bought a Futaba computer set. Excellent piece of kit. Follows, some
thoughts.....and just to prove to our visitors from overseas (and south of
Luton),
we DO have greenery, space and blue skies, here in Manchester UK!
Easy Pigeon
|
 First electric model. ARTF? What
the he...??? Ahhh! Ready made. That's good. Well it was. Wasn't it?
Build time: One evening to
assemble. Had fun digging out 30 year old X-Acto knives and various other
tools.
Maiden flight: Easy, really suitable for the complete beginner.
On a later flight.......I found out at about
1000' that if someone else has made it, you don't know how well it's put
together. She got caught in a thermal, I was losing visual, some gentle
rudder to spiral out, and the most gentle recovery I could do was far too
harsh. The poor thing just folded on me, and fluttered down to earth like
a wounded butterfly. She recovered, though, thanks to the rep (new
wings!). Good man.
I fly her with a six pack of 1500, and 2000 SCR's, (buggy packs) and
get about 15-30 mins ave. thermal hunting. I need to install a SP500/buggy
motor when I get around to it.
NOTE: There is no reinforcing across the wing spar! The
spars just butt together. Bloody shameful. Keep her to minimal G.
Months later, I stuffed her into the top of a
tree adjacent to the cemetery, about 60' up! Well, I'd recently bought a
new set of drain rods..........
"Hey Sarge, there's this bloke wrestling with what looks like a
50' snake........"
Drain rods are bendy, of course, everyone knows that, don't hey?
Next: Ahhhhhhh! I knew kids were
born for something useful. Up you go, lass. Well, 11 year olds don't weigh
much, you know!
The last flight I had with her was a very
thermally day, they were poppin' up all over the place. Flying her towards
me at about 300', and she did a wing flip (180°), she was now
upside-down, still coming! I was truly surprised at the violence of the
flip not snapping the wings!
All in all a good kit for the money. Recommended.

The Multiplex Cargo
|
 |
 |
 |
| The cargo, looking for her third flight,
after the dreaded climb/stall/snap! How's that for a strip? |
Look, she DOES fly level (using mixing on
elevator) |
An early flare, ending up as a real greaser.
Great fun! Carrier deck comps, anyone? |
|
Comment: Multiplex have really dropped the ball on this
one. The CG needs to be 1¼" forward of the plan position (thanks,
Roy - Mega Models), and should have DOWN THRUST built in (about 2° should
do it), not upthrust. What were they thinking???? If you build this as per
plan/instructions, it WILL unstick after 10'-20', and launch itself
upwards at about 60°, stall, and come back to you. The snapping sound is
not nice. Ouch.
I've used a Ripmax Extra 50A (great items, I wouldn't use
anything else, now), with 7x2000 SCR's. About 7 mins, semi-carefully. She rolls,
too. If it can carry 500g, why not another flight pack? 14 mins?
Just don't open the doors!
I
bored out the nose, as much as was sensible to get the flight pack as far
forward as possible, yet I still had to batter some lead in the nose. Two
HS-55 Hi-tecs at the back end give the push/pull on rudder/elevator. This
is destined for LED landing lights, with those high power white lights.
Should look good at dusk on finals. I've found her to come
in on finals very fast, and floaty, so I crow brake her in. Make her as
dirty as I can, but she still floats on, and on, and on (Ariston?).

Crazy Sparrow
|
 |
On me 'ead, son! |
|
Underpowered. A lot. I've just read about how to cure it.
A new motor/box/prop combo. I'll post it soon. Trouble is, when you see it in the box, you just plain
can't resist! Looks really well in the air, but it is very fragile on
landing, the main gear just needs a bit of beefing up. Back

Miss Europa
|
|
On the strip.
A lovely park flyer, a great
first model. No vices at all.
|
Speed
400 7.2v running an 8"x4", through a 1.5:1 Graupner box. 3 x
HS55 Hi-Tec servos. Superb. |
|
I run two packs,
7x500Ni-Cad's, gets about 10mins, and a 7x1100 Ni-Mh gets you about 15
mins! ROG (not grass) a bit twitchy, it ground loops for fun! Just the
ticket on those balmy (!) summer days. Back

Twinstar
|
Twinjet
|
|
The
Twinstar. A great little performer. Get one to-day! Poke through the
spinners with a pin, then press the props on FULLY. They won't come off
(unlike my first flight with this one - wheeeeiiizzzzz .....splat!) Now retired to that great
dustbin in the sky.
|
My
Twinjet. Great machine. Still flies in almost all weathers. 7 x 2000SCR.

Spitfire
|
|
To
get here, you have to do a bit of this
|
Doesn't
take long with a kit of this quality.
|
| Balsacraft Spitfire. What a great kit.
Cyano and CNC parts were a revelation! How easy the Spit went together. I
installed, as per plans, but I put a dual conversion Rx in. Mistake. They
don't like electric. After a roller-coaster ride in the sky, I put my foot
on the floor, and pulled the Spit out of the ground (she'd buried herself
about 4" in!) and pulled.
Slooooop! Out she eventually came. New kit
installed, and some repairs (amazingly little damage, but now I know to
allow for batteries coming through the front!). I found her to be very
responsive (on 7x2000 SCR's), but a bit too quick for me at the moment.
She is currently retired, but will be flown again (when my adrenaline
levels are too low!). GWS (pico 4ch) receivers rule, OK! Back

Misc

Forgotten
this one, hold on, it'll come back to me.... ah yeah. A Jolly Roger. Check out
that tranny! It let me down in the end
(Skyleader).
It disappeared vertically downwards into a field (max revs -
natch), close by and in plain sight.
I spotted the point of impact, took a distant transit ( a big tree), and
walked towards the tree. I should by rights, have trodden on it
(the grass in the field was only about 4" tall). But even with the
assistance of a passing Bell 47G crop-duster,
it was never seen
again................ Dun, dun duuuuunnnn (drum roll, exit stage left).
Mind you, I started when MacGregor was putting out those
anodized blue bits of stuff they laughingly called radio gear. Before
launch, you had to wind up the rubber band on the escapment - truly!
Single channel never ruled, and it wasn't OK!
Old stuff - when I wuz a lad......
Literally just
bit the dust - in the days of no silencers. The hook just behind the
TE on the fuz is the winding eye for the escapment (rubber powered servo
to you newbies!)
|

Vernon
Mini Robot s/c (single channel on rudder only - max deflection right
if you press the button once and hold. You get left by pressing, letting
go and pressing and holding! A right royal pain in the bum!). You
can see the actuator arm out of the fuz and up into the rudder loop |
Cobra
C/L (covered in silk), with Merco 35.
|
Keil Kraft Gazelle
C/L (with DC Spitfire I think). Good fun.

Things that are good...
1) Super Nova chargers. Wonderful piece of kit.
2) Ripmax Extra ESC's. Good value for money, a proportional response
to your left thumb.
3) Balsacraft kits (Hah! Good luck finding them!).
4) Four 400 motors on a model. Shifts anything.
5) Electric flying. Nothing to clean, afterwards. I get more hours in
per week than any power jockey. (Doesn't mean I can fly any better though!)
6) Gunther props for 400's.
7) Gold connectors and silicon sheathed wire.
8) GWS pico 4ch receivers. Some reports of range problems, I don't fly
that far away, something to do with failing eyesight........
10) Bo Derek.

Things not to do again...
1) Put a dual conversion Rx in an electric installation.
2) Use a Multiplex IPD Rx with a Futaba Tx. It doesn't work, servo chatter
all the time. Even on the bench.
3) Buy a Hi-Tec ESC. The BEC doesn't work. At all, from new. I thought it
would do my Cargo, reverse would make for fun taxi-ing.
4) Never, I mean never let the smoke out of the 'plane.
