Keil Kraft Caprice

Next project is this old timer, going to be 2 channel rc, with a bit of creative thinking it should all fit.
I'm considering moving the fin on top of the tail plane (would it still be a caprice?).

I have seen two of them converted to single channel radio and both worked well using the original fin size and location, but with a bigger rudder. There is a video on YouTube of them somewhere

Doug, I see you still haven't opened and read my PM of the 12th December, don't you think that's just a little bit rude?

Perhaps he doesn't know how to?
Depending on what he is using to view the forum, it may not be obvious where PM's are or how to get to them?

He has answered mine in the past
I think he knows how

This is a thread about the KK Caprice so is there anything wrong in ignoring inappropriate posts? Definitely not rude.

Doug, since you do not open your PM's (but you know how to) as an administrator my only recourse is to address you in a thread that I know you are reading. When are you going to open my PM sent in December and answer it?

Klippy is just using this opportunity to get a message to, and get a reply from Doug, he can clean up the thread and remove any posts not related to the Caprice later.
The Caprice is another one I tried out when I was a youngster, I think it's a beautiful model and should easily convert to 2 channel radio, but try to stick as close to the original as possible please Paul.
Are you going to tissue & dope it or use heat shrink film?

Pol.

Yeah, go ahead and move the fin. As much as I'd like to see it as original as possible, the fin is a problem when landing is it not?
If my memory serves me correctly, I seem to remember having to do some emergency repairs on site every time I flew mine.
Correct me if I'm thinking of another model please, ..... it was many years ago. :lol:

Pol.

it'll be tissue covered along with "ezedope " so nice to use, no smell and it cleans up with water, I'm actually sensitized to real dope, gives me a streaming nose and sore eyes.
A little progress today.

Fuselage looks even thinner now I've cut balsa!
Think I'll take you advice Phil and leave the vertical stabilizer as drawn, may beef up the attachment, I hate butt joints...

Does that stuff shrink as tight as the old fashioned dope?
I used to use several ultra light spray coats of the cellulose dope and I got a really tight skin that was very light. it did sag a little though when I painted it, but I can't remember what I coloured it with.
I prefer heat shrink film now, although I haven't had cause to use it for a while, .... HobbyKing sell it for peanuts. :lol:

The rigidity of doped tissue is a valid point.
It was popular, when no other lightweight covering materials were available, to build was was in effect a pretty flimsy single spar wing structure (to save weight) that relied heavily on the doped tissue to provide torsional rigidity. The down side was the tissue ended up 'brittle', prone to puncture and of course damp conditions!
The heat shrink films are both waterproof and much more puncture resistant but as a result are also more flexible. With the same style internal structure a film covered wing is likely to have lower torsional resistance.
It may still be adequate but if a 'free flight' glider is given a Tx controlled elevator it can be made to fly faster than would ever be possible with just 'natural' longitudinal stability in free flight.

Pol, there were coloured dopes, and coloured tish, too, but the tish colour was pretty feeble in comparison with a pigmented dope.
You could always tish and dope it, then solarfilm on top for colour.

One of our ex-members used tish and that water-based floor varnish for his models. When I tried it, I got a horrible mess, because it foams up if you over-brush it - then the foam dries faster than the rest!

Found ezedope to be just like regular dope but without the smell tbh, if litespane was still available I may have used that, not a great lover of film finishes, each to there own of course and if I was building a modern glider then I can see the attraction.
I just like tissue, it's cheap ( hobby craft sell 6 sheets for a quid) and I like the fact you can repair it in the field, I know it's delicate etc but I'm just weird......

not a lot of progress over the last 2 days....got a dose of man flu ( all sympathy gratefully received).
Fuselage is 90% complete, need to get my head round a few radio/control run installation problems, made a start on producing wing ribs but I could really do with some thoughts on the following..

any idea of how to build in the elevators?
not really keen on the trim tab type of thing, over to you chaps.
