well I flew for about 2 minutes this morning and broke the rotor head. At least just the rotor head snapped and the flybar bent and one link connecting the blade grip to whatever it connects to broke, so I guess that isn't too bad. The blades and grips and everything are all intact. Would the main shaft get bent or is the head pretty much meant to snap like that so that nothing else breaks? I hope I can find parts in stock this morning. Damn hobby shops don't open for a bit.

Get the CNC metal head, Very strong and usualy just your blades will break and head shaft could bend in a ver hard hit.
I have yet broken any metalcnc parts in any of my crashes..

yea, but do you realize the blades are 25 dollars and the piece that snapped is 5 bucks? flybar is going to bend no matter what.

When the head breaks it took other parts with it. All of my ball links, fixed pitch links, mixing arms, washout arms, stabilizer bar, and anti rotation bar were toast. The last plastic head I had broke in flight and it cost me $50 in parts and I didn't buy new blades either.

I know I've made several posts about the plastic head's strength but it just isn't up to the task. In my opinion the main hub shouldn't be designed to be a break-away part in a crash. I don't think it was, but if it was that philosophy would lead to issues since it is the highest stressed part on the heli.

But it is just a micro heli. All of the pieces are so small that it is bound to have a few design issue here and there. There hasn't been the perfect micro heli yet. Well not one as cheap as this one.

I second that. At least get the alum rotor head. I bet that's the part that snapped.

yes, but on mine, all that broke was the center hub, flybar got bent, and the pitch arm broke, I lost the boom supports too. So if I got the metal head, god knows what else would get broken. Two hobby stores later and it seems like it is ready to fly again, although now its too windy

I think I might have busted the servos but I can't really tell, they seem to have some play in them.

Good luck on your next flight. Hopefully it last longer than two minutes and won't cost you any money.

How exactly did you break this morning? Did you lay it over on its side? Just curious as to how you spared the main blade but bent the flybar.

I'm not really sure, I came in kind of hard and a little forward so I think I hit the blade into the ground and it just popped the head right off. The blade got slight damage to the end, some of the schrink wrap tore so I put scotch tape on it, I have another set of blades sitting here if I need them. And lets not over estimate, it was more like 60 seconds or less

well it was 30 seconds this time and the head is now broken again, blades still intact though. but this time I lost one of the screws that goes through the head and into the seesaw assmebly with the gold collar. This should be fun to replace. I'm going to try to jbweld the old center hub that broke this morning. Is that a really bad idea?

Yes that is a bad idea. When mine broke in flight the blade/grip assembly flew off like a frisbee. Luckily no one was in the area becuase it have probably left a good bruise or something.

Why risk using the jbweld? The risks definitely outway the rewards on that one. You have safety, the rest of your heli, and the time to do it all weighing against using it. Just wait until you get a few more hubs in your field box.

Just a quesion, but are you new to flying helis? If so then some training gear might help you not to go through as many parts.

I could hover my nitro .30 pretty good, but that was 8 years ago. I have the training gear, its not doing much good though. I think the accident this afternoon happened because A. it was windy and I was dying to fly and B. the servo gears got damaged during the morning crash so I think that contributed to the problem. The head part won't be in until friday and the head from this morning broke clean so I figured I would try the jbweld, with the way I've been going, why start with a fresh piece when I can just keep breaking the old one

Oh BTW, my flybar bent in the morning. I bought some piano wire for like 70 cents that has enough wire to do like 10 flybars. The flybar didn't bend this time.

I have crashed with both the plastic center hub and the cnc one. Believe me that it is much cheaper to just go ahead and get the pretty one.

I had 2 light crashes with the plastic hub that took out many other parts as well making a hell of a repair bill on both occasions. One of those expensive crashes didn't even ding my blades

. Tried the cnc hub and had an ugly crash. Broke the blades, spendle shaft, landing skids, and tail grips. Still not cheap, but cheaper. Easier to fix as well.

It is best of coarse to not crash at all

If buying the parts that make the heli fly and stay together is a problem then you probably should fine another sport because its only going to get worse.

head breakage

If you are a newbie then be thankful that the plastic head breaks - this feature has been much maligned in the forums but it SAVES you money - the head is a cheap part and it saves other breakages (usually - there will always be exceptions - the ground is hard innit...). The plastic head will never fail in flight so I would say it's about right for my money!

I wouldn't say that it will never fail in flight. I've done it. I didn't crash but yet the plastic head cost me a lot of time and money to upgrade to the aluminum head and fix things it took with it. I was doing full collective climbouts to find out the wattage pull with a watt meter. The head broke at the seesaw and took the horizontal fin, boom supports, ball links, flybar stabilizer, seesaw, head, pitch links, and a washout arm. All that without break a blade or bending the flybar. The heli landed and stayed on its skids though.

That plastic hub is the most expensive $6 part that I have ever seen. It saves the blades, but takes out everything else.

btw, PM Matrix Mimi for those bling parts. He carries them and sells them for cheaper than what you can get elsewhere.

I disagree about the plastic center hub taking everything else. It may and it may not. So far I've broken the hub about 3 times or so. And usually all I've lost is the screw and metal collar that goes into one side of the seesaw. I've lost one or two of the plastic pitch rods and I think I lost one linkage rod. The first time the hub broke the flybar bent but a piano wire music rod has held up the rest of the times.

I may be wrong then. If the plastic hub is working well for you then stick with it. I only have a limited number of crashes to go by. For me, it didn't work out.
