KGB - 29 May 2006 13:55 GMT
Hi

I have been out of the hobby for a year or so and, to get my
motivation going again, I am currently building a small foam electric
model (Miss Hanger One). On MH1 the foam control surfaces are merely
sanded at 45degrees and hinged using "Dubro electric flyer hinge
tape".

However, I am more used to building larger models (up to quarter
scale) and control surfaces fitted with "proper" hinges securely glued
(and pegged) into solid balsa - hinging with tape, even on a small
model, looks a trifle insubstantial to me.

When using hinge tape on electric models, is it normal practice to
just apply the tape to one side of the control surface or should I
hinge both sides?

Regards

I do both. I don't use tape - just a strip of solite each side, then
cover the lot with solite again.

On larger models, solartex or solarfilm is good.

FOOL!  Everyone knows if you want to be taken seriously you have to have a
scale model running 4 stroke petrol engine.  Its bad enough to buy an
electric but to make one out yourself out of foam and tape?  Geez.

Hi

Thanks for the helpful advice.

Alas, I do not possess a 4-stroke petrol engine.

The nearest I have in my workshop to such a beast is:-
Saito 56 4 stroke
Laser 150 4 stroke
Laser 200 (V twin) 4 stroke
Zenoah G45 petrol
Plus assorted smaller engines  - glow and diesel.

I am simply not used to foam and tape; my current meagre collection
includes:-
Paper Aviation "Regal Eagle" (large cardboard model!!!)
1/4 scale Mick Reeves Sopwith Camel
1/4 scale Glen's Models Extra
1/4 scale Flair Tiger Moth
1/4 scale Precedent Stampe
Flair Puppeteer
Plus assorted sports, funfly, glider models and "own designs".  I
would point out that all these involve some limited skill with a craft
knife and the ability to stick two bits of balsa together rather than
buying a "Ready to Fly" model.

Unfortunately, my workshop is a shade too small to build any more
biggies, so - having had a break from modelling for a year or so due
to moving house, I thought in my foolishness that I would try
something cheap and cheerful to rekindle my enthusiasm for the hobby
and that I could literally just throw in the car and fly without
getting any of that nasty glow fuel on my nice new Rohan trousers.

I apologise if I offended anybody by building a feeble flying electric
model - just how feeble, check out the videos (especially video 1)
at:-  <http://www.redshangarone.com/products/miss.html>

The nearest I have ever come to a 4 stroke petrol engine in a plane,
was when I had an aerobatic flight in a full size WW2 Stearman biplane
over Los Angeles - now that I can recommend.

Regards - apologetically    8^)

My Zagi has tape both sides but my little 3d style pitts has tape on only
the top surface on the ailerons and elevator and both sides on the
rudder(for cosmetic purposes only)and touch wood is been fine so far

I can understand your concerns, tape does seem a bit dodgy when compared
to other methods.

If it bolsters your confidence in trying the stuff... I have used it for
taping the elevons onto a zagi. The zagi did not have the most
comfortable of existencies on the slopes I fly off. It has been
repaired, recovered several times but.... the elevons never once fell
off !!!

There are a variety of tapes you can use but I would do both sides of
the control surface. A lot of people have found "Diamond" tape to be OK,
if you haven't seen it then it is like sellotape but very clear and
apparently isn't unduly affected by light.... local stationary suppliers
is where it can be found. One good thing with an electric jobbie...
the fuel ain't going to bring the tape off     >:-)

Chalk another up for the everready brigade.  As for offending anyone nah,
Macgyver would be proud.

and as for anymore nay sayers of electric flight check this out

Hi

Personally, I think it needs trimming properly - it obviously won't
fly straight and level.        

And as for the crappy ground handling at the start of the flight, he
clearly has a sticking wheel!!!!!  

The last model of mine that flew like that was when the tranny aerial
fell off half way through a flight.                

Regards             8^)          

P.S.  To get back on topic, I wonder how he hinged the control
surfaces.

    Diamond tape or similar on both surfaces is the way to go

Yes, 'Diamond' tape is the way to go. It is very clear so does not spoil the
colour scheme, it resembles slightly thick sellotape and comes in small
rolls.

Like sellotape the security of the adhesion more depends on what it is
sticking to than the strength of the material. For solarfilm, profilm etc
where it sticks well, a piece on one side is fine for speed 400 type planes.
I use it in one piece, the whole length of the hinge, and to remove the
'unsightly gap' then apply a piece of film over the top. For foam maybe both
sides is needed but it is much stronger than it looks, especially as there
is no fuel to compromise the adhesion.

As a final tip, rub the tape down firmly with a fingernail after application
