Hubsan X4 Race Chassis (v2)

English:

Inspired by http://www.thingiverse.com/thing:636591, I designed a comparable racing chassis for the original Hubsan X4 (first generation, featuring only two LEDs) with 7mm motors

The PLA-printed chassis weighs approximately 85 grams, nearly identical to the original. With a stripped-down keychain camera (http://www.chucklohr.com/808/index.shtml) and a 380mAh battery, the complete copter weighs a remarkably agile 43 grams, enabling excellent flight performance

v2 Modifications:

Following several flights and crashes, I implemented subtle enhancements to bolster stability while maintaining weight. Version 2 boasts reinforced connections between the arms and the central body

Inspired by http://www.thingiverse.com/thing:636591, I designed a similar racing chassis for the older Hubsan X4 (the version without LEDs in the arms) using 7mm motors. The PLA chassis weighs a mere 85 grams, almost identical to the original housing. With a low-cost Chinese keychain camera (http://www.chucklohr.com/808/index.shtml) and a 380mAh battery, the fully assembled copter weighs approximately 43 grams, allowing for exceptional flight characteristics

v2 Modifications:

After several flights and crashes, I decided to reinforce the frame slightly without significantly increasing the weight. Version 2 now features stronger connections between the central section and the arms
