I started a build log for my 4f200 to hopefully pass along some information, build a database of sorts and maybe help some people with this very awesome helicopter. The methods and opinions expressed here are my own. Links to other peoples project reserve their own methods and opinions as their own as well. These methods and opinions are to be used as a reference point only. Follow these instructions, methods, and opinions at your own risk. The authors of these works will not be liable for damages to you or your property. Please always take proper safety precautions and use proper safety equipment to protect yourself.

To start off i want to just say that if you own or are planning on buying one of these helicopters. In my opinion, it is absolutely mandatory that you upgrade the receiver (2612V) with a 2618V RX at the very least. There are better and more expensive receivers/gyros you can buy. But the 2618v is stable. It will hold the tail and fly very nice on this helicopter. Unlike the 2612V.

First I am going to cover a few repairs i recently had to do. As I crash and rebuild or modify this helicopter I will be posting new information here. As well as editing and updating existing posts. Check back for edits and updated info. Subscribe to this thread by clicking the link above to receive updates on new posts.

My fiber frame pieces were broken so i had to swap them out. Surprisingly i had at least 20 or more flights with the frame in this condition. Replacing the frame is quite a pain. The most important thing is keeping your screws organized. You might as well clean up and check for wear. Repair or lube things while your in there too. I happened to find a worn gear cap on my front tail drive gear. The only other issue i saw was some wear around the outside of the outrunner on the motor from when i crashed the frame rubbed the side because it was broken. I also had to rebuild the tail and replace the belt. More info on these repairs in the coming posts.
