I bought my Type - A after flying a Syma X1 for some time. I want this build log to be a reference for people considering the chassis (I'm really glad I bought an RTF, it's hard enough learning to fly without having to learn quad PID tuning too). The V1 Type - A isn't on the website anymore, but most people are familiar with the general components.

Here's the V2 that's available now: http://www.helipal.com/storm-racing-drone-rtf-type-a.html

My big revisions have come each time I've really wrecked this thing (full drop from 80 feet twice in one session, and low @ roughly 20 mph on pavement earlier this week).

Changes/Upgrades

• Printed a new upper deck from ABS (5g lighter than the carbon, and more crashable).
• Removed all but 2 JST's from the power harness. Shortened ESC signal wires and relocated ESC's.
• Mounted vTx on the upper deck.
• Added GoPro mount.
• Using Gemfan 5030 3 Blade's for now.
• Been through a few revisions on motor guards and landing gear, all 3D printed. Will keep this updated with revisions, and happy to provide STL's for anything on here.
• Adding a circular polarized antenna set tomorrow. We'll see how they do. (Update: The Neewer's shown in my parts list show up in a Boscam box. They also showed up SMA male, opposite from Amazon's photo)
• Replaced all columns (by necessity, they were bent) and went from 6mm on the lower deck to 7mm. Helped accommodate the ESC's.
• Added 90 degree Rx Antenna Mount

Definitely an ongoing process, lots of crashing. Should be good information for others starting out in 250 quads. Feel free to tell me what I could be doing better!

Cost list can be considered as a real cost of ownership, I'll list all consumables and anything I have to replace beyond the RTF kit.
