Where did you get/buy the 3/32 nose gear wire?

Your location might help here.

Music or piano wire is hard wire that is sold my most hobby stores and can be ordered online through places like Tower Hobbies, SIG, and various balsa suppliers like Balsa USA. A number of places also sell pre-formed landing gear that may or may not need trimmed and the final bend made.

Drill rod is another material that is used. It is a high carbon hardenalble wire usually sold annealed, which is still pretty hard compared to common mild steel wire. For most hobby applications it does _NOT_ need to be hardened, and hardening is a non-trivial process involving heating to about 1450F (cherry red) and quenching with the correct cooling method, then having the temper drawn by reheating to a suitable temperature typically around 400F-500F. A2, air hardening steel, is popular for flap and elevator horns used on larger control line ships. Again, for our purposes cold formed with the correct radii the annealed drill rod is plenty hard enough in most cases. This can be obtained online through suppliers like McMaster-Carr, Fastenal, as well as through local metal and material suppliers.

Hello, please leave your message !.
You can use steel rope, there in the US there are plenty of houses that sell bouquet, or you can use "piano wire" of 2.5 mm and manufacture the curler for the nosewheel. Do you get me?. Greetings, Mauricio.

Hello !, If a kit, just not bring ailerons and I will add a micro servo for each wing, which makes the flight much more even and dynamic. When placing flaps in one and two positions, it becomes a great "flotón" and you can enjoy a long period of flight with the engine already planted.
much appreciate your participation in the forum !, greetings...Mauricio.-
