Beside one model, all of them are copies of that my old "GB r3 like" model, with minimal engine offset (sidewise), and straight rudder

that "other" model is form R/C kit and that one has all straight (sidewise ... I write sidewise, because motor has ~3degrees down offset)

however lines are approximately 20 degrees back, and that is also in-flight yaw, it does not need significant rudder and motor offset, because of well balanced side area, what is easy to do on such type of model (knife and glue are quick tools for that ) ... so that extreme yaw is then easy to trim by only minimal motor or rudder offset

means the line tension overhead does not come from centrifugal acceleration, but instead of that from lift on fuselage side, you can see that the area of fuselage is similar to that on wing :-)

flying is surprising, experienced c/l pilot will never believe, that it can do eight onerhead, because he will feel, that centrifugal force canno keep tight lines .. but it does, and more, it NEVER fall from lines, and it makes it good tool for learning figures

and no, we do not have flaps, flaps are not necessary, you can have any amount of area, since we do not have any wind and thus we can fly low wing load and if you look polar of flat wing, you will see that flaps are counterproductive and more, low lift coefficient means low turbulence on tips of wing and thus almost no self turbulence in calm condition of gym

yes 3mm wil save you half of the weight :-)

gears, pans and legs are part of the flying area :-)

it has 80cm span, 170g weight, 60W motor 32g heavy and 2s 800mah battery with Spin 11A ESC

Yes, it is almost usual F3P model, my first try was just that. But there are 3 differences, the nose has more side area, because usual F3P model has shorter nose, and that leads to more rudder offset for proper fuselage position with excessive outboard yaw (it is almost 20 degrees). And the secon difference is much stronger powertrain, it has 60W motor, larger prop and battery is 2s 800mah, while F3P uses 30W motor and ~300mah battery. And the last is, that we have aproximately 3 degrees down motor offset, while F3P little right, so the mainframe must be little modified, but that is easy to do by knife 

CNCed bellcrank is on picture ... we all use the same

Just make little bit wider or longer nose than on F3P, I can send you corel draw file with my model if you want measure what we have here, but I succesfully reworked model from this link, the difference was only little out rudder - it is not big problem, but fuselage makes side lift and outboard rudder makes it lower, but it will certainly fly.

You will certainly need ESC with governor, I use Spin11. Motor is 32g heavy 1400rpm/V with internal resistance 150mohm (that resistance is important, becaus motor runs overloaded). I do not think you can find turnigy equivalent, we had bad luck with low cost motors, they easily burn, just imagine what happens with such small motor and such a prop. I would say it will need to be little bigger if you want use such types. This one comes from Czech and its name is Python 60. It is little more expensive than turnigy, but we all use it and it works well. Try to search some motor by KV and resistance and do not look to weingh, you will probably come to heavier motor, but I think such a model can carry it easily.

you can look also to this older page, pictures show shapes and areas. Span is 80cm.

it is difficult with cemech, they found it is easier to resale stuff and that production is difficult :-), we ordered box of motors at once and that is what we fly now :-)

200-300mohm is too much, it needs 5-8A and it makes extra 2-3watts and it will also limit current and thus torque, it is really better to chosse larger motor ... problem ise really that cheap motors does not have Ri in parameters, probably because it is typically much worse than those more expensive, but may be scorpion can have good type

I can send you CDR file, can you read it?

Friend of mine, Marep Petovsky did a pdf with dimmensions ... I will try to post it here.

It has czech comments, but I think all was already written here.

or this one: http://www.modelmotors.cz/index.php?page=61&product=2208&serie=26&line=GOLD

I see you are learning Czech :-))))) ... yes teziste is CG :-)))

  great
