Hi,

I have never had a glider with a V-tail, and would love to have an idea on the recommended throws for elevator-rudder (elerudder?, ruddervator?, elev-O-ruddermatic ?).

I read on the retroplane forum that ailerons at +30/-15 mm is a good starting point, but no mention that I can find on the tail movements.

Did anybody took some notes (and remember where they are) when he build it, or are you like me ?

Best,
Miguel

Hi,

I have started building the K3. Or at least, I have started the thinking about building. Love the plane and love the plans.

I will use DevWing to get the ribs straight to the cutting machine with a HQ profile.

Am I right measuring dihedral at 3º, wing incidence at zero and tail at -2º ?

Best,
Miguel

I was thinking in HQ 3.0/12,  Eppler 201, or Eppler 195  for this wing and 2.5% dihedral with carbon tube main spar.

Best,
Miguel

Hi Fred,

thanks for the welcome, I will order a 1/4 scale Grunau Baby, and put a comment. 

Can you please elaborate on the wing changes that you plan to redraw?

Thanks and nice flights,
Miguel

Note the link says Opel Rak, but it is in fact the Ka3

Great model to fly by the way

Thanks Ralph,

I noticed that the name of the link is not right, but it is pointing in the right direction, that shows no availability for the plan, unfortunately.

I am on the list for "Notify me when available". Let's see.
If it doesn't work, I will use your kind offer for help and pm you. Thanks again.

Anyway my requirements are simple: I want to know how to purchase a set of 1/4 scale Ka-3 plans and have it sent to Madrid Spain.

And yes, I also think this is a great model to build and fly.

Incidentally, I have been lurking a bit on the forum it it seems a nice community that you have here. Congrats.

Best,
Miguel

Hi,

This is my first post in this forum and I understand that I am resurrecting a very old thread. Sorry

I love this plane, and 1/4 scale suits me fine, but I do not find a "Shop" tab in this webpage. It seems that I can purchase in

http://gliderireland.modelisme.com/planspage.htm

but I find no indication of availability, postage cost to Spain or anything else, apart from a Paypal button.

Also, Islandmodels shows "no stock" for this plan.

Your help will be appreciated.
Thanks in advance,
Miguel
