Ikarus Meteor 1/3

Hi,

the span F1 is a kind of double to the F1A. What is the reason for this? Stability can't be the reason. Is the idea to screw the nose to the fuse or what?

regards

Thomas,
There is usually both F1 & F1A as a double thickness nose former on Jilles Smit 1/3 scale designs.
This gives more glueing area for the longerons and also usually has holes in it for the screws/bolts which go into the nose cone captive nuts.
I have not looked at the plan, but you may find that the tow release is attached to the front former.

106mm from leading edge is recommended, but I would push that back to perhaps 110 to start.

Has someone a CG without wings?

Before I close the fuse I like to install the span for the FES, but I didn‘t build the wings at the moment

It does not matter without the wings, it will not fly well anyway.

I think to build in a FES and try to calculate if its possible.

so I put a FES in the nose. It's a bit fiddly, but a 65mm fit in:

Bang goes another scale model!!

[Woody80]

for shure not, it`s a nearly invisible system, you only have a 11mm hole in the nose. when towing are no prop attached...

and by the way: the plan and the short kit are not scale, there are at least two points "nonscale"

Hi Woody, I saw the picture of mounted nose cone with drive shaft in rc-network. That shows how nicely hidden the propdrive is! I was impressed! Hope you continue your construction on this beauty with same speed! I would love to see it flying!!

Just let me know what you think is not to scale. I have done now 40+ glider designs and because most are vintage there is not much info avaialble.
For only two desigsn I was able to get original factory drawings.
3view drawings are very helpful but are only as good as how accurate the author of the 3D drawings followed the original details
Photo's on the internet are very useful but can also be confusing. Very often owners and clubs do make modifications to the exterior or the factory
has after market options and/or improvements.
On some occasions I do go off scale for aerodynamic reasons. e.g. if the stab/elevator is small in area compared to the wing area I do increase the stab area by 10-15%.
The aim is to create a scale like flying impression with good handling characteristics
