OK, I know, but it helps to fly before I give a full report. They are MicrHeli (Silver). Turning the swash with my hands didn't tell me much. I went ahead and replaced the tail boom too with the Walmart kntting needles. As soon as I figure out how to upload pictures that aren't huge, you can see the work.

Until then, here are some large pics:

Would a 9/32 drill bit be too large? I got a 17/64 drill bit last night, but it is too small.

I finally decided to change my tail boom out with one of the knitting needles. You're right, the 17/64 is a bit small. The next size metric would probably do the trick but I didn't have it, so I used a small round file and a couple other improvisations to get the tube reamed out for the motor mount to fit good. By the way, cut the knitting needle right at the cap. You need every bit of it to make up for what you lose on the tapered end. Since I found that out too late, my first replacement boom has a slight taper on the heli end.

Couple other things I discovered - putting together plastic parts with machine screws is just plain stupid. I knew this, but I have to reiterate it to show my disappointment with Heli-Max for cutting this corner. Two of the four screws holding the tail boom in the frame are stripped with very little help from me. Now I need to find that post about the hex-head screws that people are buying to replace the machine screws. Another disappointment, but more a miscalculation on my part; the tail skid will only bend back into place so many times before it finally breaks off. That number is one bend less than I used on Sunday. The result is a threaded pin the thickness of a paper clip stuck up inside the vertical fin, with no way to unscrew it. Probably not worth attempting to get out which means new vertical fin and skid. Grounded until I get those as I don't want to fly without the skid. It's saved my tail rotor countless times, I'm sure. Unless I can fashion some other makeshift solution to get flying again. Hmm..."honey, do you have any bobby pins left over from the 60's?"

I have not replaced my tail boom yet with the knitting needles yet but I got to thinking, what if you put the taper on the tail end, then you could cut it at a point where the motor mount would just fit (ie no drilling the shaft out) Might be more trouble than its worth trying to figure out the right spot to cut though.

I agree with the taper and cutting....I removed my boom (both parts!), and measured against the knitting needle, and discovered the same thing. Also, I used a 9/32 bit to ream out the end, and it is a bit loose, but not so much that I can't shim it with something. One tip though. Use some craft glue, or some CA on the vertical tail fin. The plastic mount won't hold enough, and it will turn if it hits the ground at any angle. As for the little metal wire skid....it broke off long ago, and I haven't replaced it....So far, not too concerned. The vertical fin is long enough to protect the rotor. I might put something on there ad hoc like a paper clip though...

I installed the GWS EDF 40H fan unit but I am not having any luck with the tail. It still wants to spin violently to the right the heli spins to the left I don't know what else to do to fix this problem unless it has something to do with the blades not spinning right or something like that. Any help would be greatly appericated.

dreimer, I noticed when I removed the fin that there was some kind of glue supplementing the mount. I figured it was CA. As far as the fin giving when hit, that actually may be better than it holding fast and transferring the shock to the next weekest point. But I'll likely opt for a couple drops of CA like it was.

Kenny4842, Putting the motor on the tapered end of the needle wouldn't work. The mount is bigger than the internal diameter of the non-tapered part of the tube, so you actually need to bore out the widest part of the tube (needle).

The fin gave a bit, and rotated right into my tail rotor....new rotor tomorrow! Along with a bottle of CA!

Kangaroo foot makeshift mod for AxeCP. Got me flying again real fast. There is a better way to secure it I'm sure.

Excellent mod! That's probably along the lines of what I would do too.

Me too! I'll have to see what I have kicking around.

Hey, new to the rc world. Bought an Axe CP last weekend and, of course, had to replace a few part already! No surprise there, right? Anyway, I was wondering about the main rotor gear. After my last crash, there was a lot of vibration. The gear now has a bit of up and down motion that I did not notice before and it seems to be causing the vibration. Not sure where to go from here... Should I replace it? I don't think there is any kind of adjustment I can do from what I see... Thanks in advance...

StevesRCHeli-

Welcome to the wonderful world of "What the hey is wrong with my Axe this time?!?" .

It gets better, trust me. Look for a collar on your main shaft. I remember one or two when I replaced my main gear. Also, watch for washers and spacers on the lower bearing. Make sure they go back where they were. And as always, have fun !!!

#11 Knitting needles = $3
6 Ping Pong Balls = $1.28
More Flight Time = Priceless
Thanks for all the good money saving info was just about to spend more than needed. I was going to look for some tubing but I am sure I wouldn't have thought about knitting needles.

Ok guys/gals......cool idea.

Someone figure out how to keep the pointed ends on the knitting needles. Then 2 pilots in flight knit me a sweater with their tail booms. I like blue....absolutely not teal. Of course we'll need video..........

Necessity is the mother of invention.....cheap works equally well in my book.
