Flying in Japan got crazy last year with new regulations similar to those in the US. In Japan after registering your plane you must inform the government that you intend to fly. You must have a spotter to ensure that you don't exit the boundaries of your flying site. You must inform the government if there is a crash so that the airplane supplier can investigate and eliminate the problem which led to the crash.
As I complained to a co-worker about this he asked, "Does that apply to all RC planes?" I replied that it only applies to planes weighing more than 100 grams.
"Well then, you have your design requirements, don't you!" was his reply!
I scaled down the FT Alpha to 60% on my home printer and got to work with a 3mm Depron sheet available at a DIY store nearby. I have an original, never to be flown in Japan, Alpha here in silver, as well as the 100 gram version. The 100 gram version is called Hyaku, meaning "hundred". It is not painted because it came out at 95 grams and I want some margin for future repairs. I am definitely intimidated by the thought of flying it!
I chose the 1106 6000KV motor and a very small 2S battery, along with linear micro servos. It all works, but I am not sure how well it will work in flight. I find the gremlin motor to be hard-starting. The servos don't seem to have the precision of larger ones. A flight test is badly needed!
I can do better. I have heard that UHU Por is a lightweight alternative for gluing everything together. There are also some better servos around 2 grams as well.
Has anyone else tackled this challenge? I would like to have a 100 gram mustang, for example.
I built the Hyaku using all of the parts in the original plan but scaled to 60% There is probably a better way to alter the design to get the same plane but with fewer parts. Any recommendations will be appreciated!
