Post by: gerryb on November 02, 2011, 00:01:38 AM

a few photos of the ka-3 i'm building from one of fred's 1/4 scale short kits. i've taken the fuse frame off it since i took the photos and it's nearly ready for covering. a very nice build, relatively easy for someone thinking of building a vintage model for the first time and it won't break the bank! nice one fred. :clap:  :clap:  :clap:

Nice work Gerry. You're way ahead of me on mine and I've been building for about 2 years!

thanks bill. i'm trying to make myself stick to one project at a time until it's finished. not easy when there are so many models in my head to be built. i'm already thinking of what's next on the list. are you going to finish yours soon? have you much left to do? 'twould be nice to see a few v-tails on the slope next year and it's not that far off you know!

spot on chris. yea, i opened a 'new topic' without looking where i was  in the forum. i think i'm better at gluing balsa and ply than finding my way around these web sites. now then, maybe its all the glue is the problem........

Sorry lads, quick message here. My father in law passed away this morning :( so I'm in the midlands to take care of some family stuff. I'll move this topic to scale section when I connect to the web.

Fred, I’m sorry to hear of your bereavement. I’d like to offer my condolences to you and your wife on your loss.
Such events bring into focus the really important matters of life, don’t they.

Ger, if you ‘Through a Right Wobbly,’ then, presumably, you must have travelled within a “Right Wobbly” and thereby passed through it. (A highly improbable event, I suggest, given the diameter of your waist.)

What I assume you meant by your expression, was that you imparted (or induced) a sufficient amount of energy to a “Right Wobbly” causing it to gain momentum and  thereby travel upon a trajectory. ( i.e. you ‘Threw a right wobbly‘.) However this too is an improbable event, in my view, due to the fact that Right Wobblies are merely abject terms of expression and do not posses any material form or matter to which energy could be imparted.

Given the above facts I can only suggest that in future you decease  from referring to Right Wobblies and stick, (if you’ll pardon the pun) to building planes!

And before you call me a “Stupid English prick,” I would point out that such a statement would also be incorrect.
I am, in fact, an “Old stupid English pick.” And proud of it! :lol:

Now, what was this topic about………… :?:

Great building, has your pilot been bought at AH Design's?

hi mat, thanks for compliments on ka-3.

yea, i bought pilot from ah designs. i asked for a sweater with the doppler effect on display but apparently it had been taken by someone on this very forum. imagine that!!

i hope to cover ka-3 this week, ready to fly soon

Title: ka-3
Post by: billscottni on November 06, 2011, 11:47:36 AM

What did you think of the AH Design pilot Gerry? I bought one for my KA-3 and I thought the legs were a bit out of proportion: too long?

Title: ka-3
Post by: Alan_Perse on November 06, 2011, 11:55:49 AM

Condolences Fred. Please give my condolences to your wife.

Bill I agree with you about the pilots. I have two pilots from AH Design. One 1/4 scale the other 1/5 scale. The legs on both seem to be two long. In fact I'm going to have to shorten the legs on the 1/5 scale pilot because it won't fit in my skylarch 2.

Title: ka-3
Post by: billscottni on November 06, 2011, 12:21:15 PM

It's a bit unusual, because there is a formula that uses a ratio between , (I thinK) shoulder to elbow which gives you a leg length.

Title: ka-3
Post by: gerryb on November 07, 2011, 00:00:58 AM

just spent a bit of time measuring the pilot in my ka-3 (what else would you be doing at 11.30 on a sunday night...must get a life!!).  length of head/neck is 3"; body is 4 1/4"; legs are 9 1/2". total 16 3/4".

if you multiply each measurement by a scale factor of 4, you get length of head 12"; body 17"; legs 38".

at 1/4 scale, i figure this gives us a full size pilot of 67" or 5' 7". not a very tall pilot you'll agree but the proportion of body to legs doesn't seem right.

i think the problem is not with the legs but with the body. i think it should be about 1" to 1 1/2" longer to be in better proportion to the legs. some time, when you have nothing better to do, take your own measurements and see what you think.

just make sure nobody is watching!!

Thank you all for your kind words, much appreciated.
(to stay on this topic, I replied to a few texts also, but my colleagues told me this morning they never received them! I have a new phone for a few weeks now, so that might be since day one! If I never replied to a text etc, please accept my apologies! Vodafone is having a look at that now!  :!:  :!: )

Anyway, as usual, great work from Ger!  :clap:  :clap:  Your Ka3 is really looking good!  :clap:
What colours are you going to do yours? (if you already know)

Title: ka-3
Post by: gerryb on November 07, 2011, 14:02:38 PM

thanks fred. i decided from the start that i would build a typical ka-3 rather than a specific one. so i put parts of different '3s for scale effect.
 i'm going to use the same scheme you used for your 1/4 sc model except in light blue and yellow solartex.
i'm cutting parts at the moment, so hopefully i'll be finished covering by the weekend.

Very nice build, Here in America very few people build anymore and even fewer, scale sailplanes! Kudos to you and I am going to order a short kit from Fred! Keep up the great work, Joser

Title: ka-3
Post by: Fred on November 10, 2011, 20:04:21 PM

Hi Joser,
Welcome to the forum!  :D

Strangely enough, considering the number of modellers in the US, I think you are right!
You have some very very good builder, like Fred China, but most reports from scale events only shows RTF glider (off the shelves), very few hand made / built up glider. But that seems to be the way the hobby is going to these days I guess. The technicality of the hobby is pushed backward more and more, but who is to blame? Modellers or manufacturers?

Ok, end of the OT rant, sorry Ger!  :oops:

Title: ka-3
Post by: gerryb on November 10, 2011, 21:09:57 PM

thanks joser and welcome to the forum. lots of building going on here and more to come.
re arf's, i find i go through stages, sometimes lots of building, then something arf takes my fancy, then enough of that, back to the building.
i think arf has its place, especially if you want to get into flying quickly. i'm sure lots of guys who would never have got into models did so because arf's were so readily available.  once you're comfortable flying with a couple of models under your belt, then it's time to consider building your own. with a bit of practice on easy-build models who's to say what you might take on as a project, even a ka-3!! (me climbing down off speech box).
are you going to show us some of your work joser? please do, we'd love to see it.

finally got out for 1st glider flight of 2012.  went to tountinna today for a couple of hours and flew  my new ka-3.  it flew beautifully javascript:emoticon(':D') wind was nw, about 8 to 10 kts, some low cloud and a very enjoyable outing was had by me!!!  some photos as promised.
colour scheme is not scale, but the blue and yellow show up very nicely against the sky.  thanks again fred

not taking anything away from your model gerry
i found this on the scalesoaring forum
www.scalesoaring.co.uk/yabb/yabb2/YaBB.pl?num=1303335384/45
this is an amazing piece of building

Title: ka-3
Post by: gerryb on January 13, 2012, 14:56:06 PM

thanks for compliments lads.

andy,  yea, i've seen that one, very nice work.  that's one of fred's too, at 1/3 scale.  bigger model, easier to add more scale detail (check out the framework through the canopy).

i've also been following the all tube version by olli on retroplane. amazing build altogether, even down to scale control runs for the 'ruddevators' or v-tail, which ever you want to call them!!

there really are some good builders out there, lots to learn from them.

ladies and gentlemen of the gliding fraternity, please give a warm welcome to the 'new kid on the block' (the glider, that is, kieran has been around for years!!).

kieran wallace with his newly completed ka-3 from a certain mr. marie's kit.

model turned out very nice in the evening light on tountinna, facing east.  unfortunately, not enough wind for a test flight, but hopefully next saturday we'll see it fly.

Post by: billscottni on August 03, 2012, 14:07:50 PM

Gerry,
Did you use pushrods, snakes or closed loop to operate the tail surfaces on the V tail?

Anybody know what the real thing used?

Title: ka-3
Post by: Fred on August 03, 2012, 14:54:22 PM

Hi Bill,

The real one used Push / pull system

hi bill,

i used blue/yellow sullivan snakes, stiffer than red/yellow but still easy to go round curves.
