Hirobo Shuttle Sceadu

First Crash

I crashed new Sceadu 50, due to running out of fuel while fast forward fly. I tried to auto it down, however the heli is so far and hardly see. During brief inspection, a set of main blades, yoke, mixing arms, spindle, main shaft, flybar and tail boom are damaged.

This crash costs me ¥4900 and a set of NHP 600mm blades.

Second Crash

The second always comes after the first. While my Sceadu did a fast forward fly, the engine grow plug fly off at the top of tall turn. The heli hit power wire during auto down. Before this crash, I practice 180 turn auto in case there is anything goes wrong during my fly. However, when it is time to crash, there is nothing to stop it.

This crash costs me ¥8400 and a set of Hi-product 600mm blades. There is one thing I learn from this crash: always check the grow plug before flying. 

Freya OP

This crash is unbelievable because rotor speed is only about 500 RPM when I am just going to bring the head speed up. Due to very strong side wind, Freya OP turn side down even it parks in entirely level ground and the main blade is damaged.

Hirobo StaySee

This time there is a different story. I have a crash in my Hirobo StaySee. Okay, you may say: "this is not a crash, just a hard landing." What ever. Due to the plug out fuel line and the very silence running, I did not aware of the engine can not reach the fuel at the moment. StaySee was not auto in a appropriate place; the tail rotor was hit. It ended up with damaged tail blades and a broken tail drive shaft. 

We all get some idea about how much a set of carbon tail blades could cost, however the price of Hirobo's tail drive shaft is real scare. The carbon tail drive shaft costs ¥9800 ($86 USD) by itself. I would not let my hard earn money go so easily. I had phoned several hobby shops to find the same dimension carbon fiber pipe and no hobby shop carry 7mm (6mm inner) carbon fiber pipe. Finally, I found a material shop carry 7mm carbon fiber pipe, but I have to modify a little to get it fit. Entire job of replacing the damaged carbon shaft took me about 4 hours to get the best quality job done and guess how much did I spend for the carbon shaft. Only $400 NTD ($12 USD).
