Hi there. Im new. Having problems with my tarot landing gear. Its plugged into ch7 on futaba receiver. When i flick switch on transmitter i can hear a faint click on both legs but no movement. My flight controller is a mini px4 with no aux out terminals.

OK, it's a Plane but what a fantastic piece of engineering!

This model is breathtaking!  Never seen detailing like this before:

unbelievably amazing..  but cant help thinking the guy needs to get out more :-)

Nice though it is there seems to be a group of engineers working with complex electronic equipment to achieve it ...

So compare that to the chaps working on their own in sheds who knock out equally complex models to the same exacting scales ...

Barrington Hares 1/5 scale Merlin - a fully running V12 all made by him ... he even displays his scrap box so you can see the size of things like piston rings and bearings - all hand made by him...








Then there';s the little french postman and his scale Ferrari 312 PB - so detailed that if you were small enough you could drive it ....



All equally precision made and all as astounding  ~~

Thanks, seen the Ferrari before but not the Rolls merlin very nice both of them.

Barrington Hares said that although you can scale down metal you can';t scale down oil ...  it';s either too thin or too thick for the pipes - so he can only run it for very short periods or it overheats  :rolleyes: :azn

Nice jet. Yeah that little Ferrari is something else.   Amazing

Interesting that. With aircraft you can scale down the physical structure but you destroy the surface area to internal volume ratio when you reduce the size of the model which means that it will never fly like a perfect scale replica, if you make it as a perfect scale replica.

Similar to how you can throw an ant of the empire states building and it will be fine, but try that with a person...

I wonder if you could replace the oil with something with a higher specific heat capacity and lower viscocity? Mercury or Gallium perhaps?

This is where scale has become more important than functionality, as an engineer I regularly have these issues to resolve - alternative coolants is an idea but are too limited in their practicality; to me something I';ve designed must work, if scale accuracy is important then I will try to find the most sympathetic solution.
