Regarding weight vs strength...
I used to build for strength and pretty much accepted the weight gain. But over the years I have found it is far better to build the airframe as strong and lightweight as possible. A lighter plane <u>built strong</u> will sustain less damage than a heavily built airframe.
<u>
Built strong</u> mean glue joins with larger binding areas then the pieces being joined are offering.
Mortising is a good idea to keep the piece in place and increase the binding area. It is not practical for every glued join in a model. Filleting all joins is easy and practical.
<u>
Built strong</u> also mean a covering and finish that is hard to tear. A covering in which each thread of the fabric has to break in tension and thus resist tearing and each thread is cemented to the frame.
Both do not add any significant weight to the model.
As far as wind it not the weight it's the amount of power, I fly 1 and 2 lb aircraft when most would stay home because of the wind (but these airplanes are considered way overpowered by most) and penetration is not an issue. Two of the planes in particular that are in the 2 lb range are a 43 inch span Kadet and a Easy Star both powered in the 800 watt range no problem flying them on a windy day, and both have taken some hard hits and are still flying.
I do not build helicopters that look like airplanes

.
I see many fellows that prefer ARFs and install propulsion that they trust will avoid a crash if they can point the nose straight up and climb to a safe altitude to try again. That is not my enjoyment of flying a model.
To each his own in the hobby.
A far superior method to glue fillets are gussets made of light ply (laminated pieces of balsa), and my preferred method (borrowed from timber framing) of mortising the wood to give you more glue area and a stronger joint an example of which is pictured below.
Pictured in your posting; no need to duplicate an oversize picture here.
Gussets are often used as part of the design but are not practical for every joint in the model. Glue filleting ismore practical and usable at all joints.

I thought your posting was worth some response.
No one has to agree with my outlooks in the hobby.
P.S.: for "sensei" that no doubt will read this posting.
I is evident that you (sensei) have already made up your mind.
You are asking for directions to build logs and videos.
You probably already know that clicking on my name brings you to all my postings and you may even have done that already. I do not have facilities for videos and consequently did not have any incentive to make some.
You have already made your own judgment about Zor anyway.
It would change nothing. I enjoy the hobby and wish you all the enjoyment as well.
