Today I took the Blade 300X out to a nearby field and flew 8 packs. On the 4th pack I performed a forward flip into an inverted orientation and for some reason instead of applying negative pitch, I applied positive pitch. The heli hit the dirt upside down.
Aftering pick up the 300X and inspecting for obvious damage, of which there was none, I decided to try another flight. I'm amazed it flew after an inverted crash. I wonder if the Microheli Aluminum/Carbon Fiber Main Frame made a difference in this crash. Normally in a crash like that, at minimum, the main shaft would snap and servo gears would strip.
Here's the flight video. This is a Blade 300X with the following upgrades:

The Microheli Aluminum/Carbon Fiber Main Frame for my 300X arrived on August 27, 2013. Just yesterday, I finally got around to assembling the frame and re-installing all the electronics. The assembly of the frame was pretty much straight forward except for a few items which I will outline in this blog entry. Also I want to express that I am completely satisfied with the quality of this Microheli product. I didn't experience any soft aluminum while wrenching screws tight. Every piece and screw lined up.
This blog post is organized into the following sections:
This year has been busy for me; full of non-heli projects. More busy than last year. Tonight I finally got around to disassembling the 300X plastic frame. Let me share with you, this is not some easy chore.
Upon disassembly, I noticed (see pic below) the screw that fastens the elevator servo to the frame had ripped its way through the servo's mounting tab. Do I really want this to happen again? That's a $24.00 DS415M servo. Servo is still good and the mounting tab will continue to hold the servo in place. But do I want this to happen again? No.
Picture below depicts the disassembled 300X parts placed into a shoe box. I'm done for tonight. Even though I have a new plastic frame ready for re-assembly, I'm stopping for tonight. I don't want to do this chore again. So I'm purchasing the Microheli carbon Fiber Frame for the 300X and then I'll continue re-assembly of the parts into the Microheli frame.

The EMAX ES08MD servos are an upgrade option for the 4F200 cyclic servos. They perform better than stock and are an all metal gear digital servo. These servos are also a tad more responsive than the prior Futaba S3154 servos I had installed in my 4F200. Not a major difference, although small enough to notice from a non-pro 3D heli pilot like myself.
But, modification of the 4F200 will be required if you want to upgrade, since these servos are taller in dimension than the stock servos. The rest of this post I have documented the steps I took to get these servos to fit securely into the 4F200 air frame.
DISCLAIMER: This post does not represent the one and only way of doing this. It only represents "a" way of doing it. If you are up-to-the-task of modifying your 4F200 then proceed and only proceed at your own time and cost. I shall not be held liable for any type of loss associated with the modifications described by this post.
Here is why modification is necessary. The ES08MD servos are simply taller than the stock servos.
