Flexible plane on robotic parts

[vv3k70r]

I was trying to make something submersible with electric propulsion and I build a fish (with controller to animate), but aerodynamic part dosent seems to work common sense underwater (for many obvious reason for anyone who made physical engines for game, it is not a kerbal submersible program). Day later I consider to check if it would work with a plane. However small enough servo and pistons are not about to handle wing movements to give any reasonable lift (and then considering power usage) by wings as a bird do so I have to stay with a jet engine for beggining. I sued wheesley because it is good test engine (even without thrust vectoring) but it could be any engine.

It dosent have any control surfave as elevon.

Plane have 2 g-11hinge. One between cockpit and fuel tank (moved 3clicks by absolute toward cockpit, and tank same way + servo) and second cockpit-engine. Hinges are responsible for pitch. Traverse rate and angle limit is responsible for how fast and agresive is response - I set it to very responsive on +/-30deg and max speed. F12 servo is responsible fo roll with same values. Damping at max but it worked with other settings too. I do not yaw for anything other that tankers and rockets. Autostruts to grandparent.

Because of this robotics lack of power is an issue on low speed alternator with landing, so there could be just one atempt without extra battery (but I landed this on first attempt with breaks set before touchdown as I always do to the planes by setting them on the spot) and then plane looks quite a dead:

Manuverability is better then expected:

Drag is very low, but solution with juno and frontal intake could be more intresting. I try later with smaller wings.

There is no other use for this then stunt and it is not a propper way to use whole wings as control surface. But I found it as intresting solution.

Of course as for all robotic parts there is a Kraken on runaway, but it dosent prevent from taking speed to fly very fast. When in air Kraken is gone that indicate where Kraken live and is against robotics.

Here is file steam workshop:

Kraken is gone.

I tried with juno, flying is more intresting but lack of propulsion force me to add horizontal surface (and in case of stunt I set SAS to prograde to get any orientation what is current vector). It is very touchy but I suspect birds feels aerodynamic fromF12 much better and it is why they have more control surface.

Takeoff is safer with speed around 60, but it can around 30 just the tail is a bit long.

Taking is a manouver similair to atacking snake - gently touch on pitch up, and then directly pitch down to stright flight - otherwise it will do the loop and with this weak engine it will end up on lower altitude than loop begins.

Landing is easy - turn of engine, set breaks and lower to hover over ground untill lift is gone around 30m/s.
