New head dampeners

[BigVanVader]

What orientation were you in when your link popped off Rodney?...Also,how tight were the blades in the grips on Bobby's machine?....I know that you tighten the crap out of your blade bolts just like I do Rodney.....if Bobby's were a little looser than what we are running then that could explain why you were able to save yours and his couldnt be saved....orientation at time of link popping off is another variable.
Sorry to hear about your crash Bert,Bobby.

Thats true Vance

Just got off the phone with Tim.... He has yet to receive the head.
Delivery only takes one day between these locations. Once Tim has the
head, he will be able to tell which dampers Bobby installed.

The pilot Karl is speaking of was indeed running the faulty dampers and he did have a boom strike.... nothing secret about it. We need to see which dampers are in the head....plain and simple. Send the head back.

From my experience in the last 13 years of flying 3D I will also say that the dampeners have very little to do with boom strikes.

This is exactly my experience as well and is why I was looking from the start for what happened and will not just go along with the idea that it was soft dampers. I still run the 70 O-rings and about medium on the shim combo and I never change them, I’m talking several hundreds of flights. I fly smooth and my stuff lasts a long time, so long that I seldom get to talk to the gang at Min Air because I don’t need much. Ever do a long (several hundred feet) vertical dive and have the model hook at the bottom during pull out? I have done this tail down and give aft cyclic to recover inverted and had it hook, only did this a couple of times and still did not hit the boom, I did cringe though! I have done this with an SE where the axle was so loose it could be rocked like a teeter totter, the dampers where basically not touching the axle and no problem. Damping being to loose will cause sum funny things including pitchiness in fast flight witch makes this hooking tendency even worse, my old SE had like a thousand flights on those dampers at that point. Like Eric said damping, soft medium or hard has more to do with the preference of the pilot and how he likes the model to fly and not to much to do with keeping the disk out of the tail.

Your calling Eric and the rest of us Min Air reps and pilots bold faced liars when you say we will say any thing just to tow the company line this is crap and you know where you can stick it!!! If you don’t want any field support from company reps then maybe you should fly a Nexus 30, then there would be nobody to help you or lie to you either. Have fun with that!

Im Done, I Wanna Hear From MA On This Subject!

Karl Nelson

[WillJames]

PLEASE lets leave the speculation and finger pointing and pot stirring out of this discussion and just wait and see what is determined from the inspection of the head. I know Bobby, I know Bert and I know all the MA guys as I fly with all of them and they are ALL good guys and truthful. I really don't think anyone is covering up anything, and if the mail down there is like here, it takes priority mail 2 days to cross town! :DOH

Arguing and bickering about it is not respectful to anyone involved or the members of this site.

Thank you in advance for waiting it out to see if it was the dampeners or something else that caused this crash. Until then, burn some fuel or electrons and have a good and safe weekend!!

Karl, lets chat on Skype.

Rodney, there is a big difference between losing a link in forward/backwards flight with pitch applied and losing a link during a hover. I don't know exactly which orientation you were in but I don't think it was a snake. Correct?

Matt

:shock:

[00boto]

HAHAHAHAH..... That made my night Jerry!

[BobbySmith]

I run my blades very tight Vance

Matt i sent it priority mail they will have it tomorrow @ the latest it ususaly takes 1 to 2days by mail

Linked popped off?? there was no blade flutter just a straight explotion all it needed was a fire and it would have done well for the movies

I have 6 more sets of dampeners and also have pics iam very curious to see what gets said
Bobby

[00boto]

Thanks Bobby!

Matt

[BobbySmith]

Here is what is left of the head

[00boto]

If he was in a snake with cyclic and collective applied, there would not be flutter, the blade would instantly dig in either positive or negative and then game over. When a blade doesnt have a link it can pull some pretty ridiculous pitch, this could be why both the blade broke and the boom was shattered in three places. Even with 50D dampers, it's very hard for the blade to dig that deep into the boom and boom supports. I bet both boom supports were chopper in half as well?

[00boto]

Bobby,
Have you ever checked that blade grip for stress cracks around the arm after some of the crashes you have experienced? I've seen many pilots out there unknowingly running cracked grips.... its kinda hard to tell unless you look closely.

this was a new Stratus Beast flew @ IRCHA se and Mulberry (with O rings) and it was rocking

Some of you need to grow up. The situation is to be between Bobby and Minair.

I had a boom strike the weekend of the BlackSheep Event , and that was atleast 2.5 to 3 months ago. Since then Miniature has worked hard on the dampers to correct then. I know of several people that have been flying the "newer ones" for some time now , with no problems.

All I ask you to do Bobby, is to let Tim check everything out. This will be a start .I'm sorry to hear about your loss..

[Jerry]

Thanks Henry for jumping in and setting the record straight about what dampeners you had issues with.

Perhaps an interesting piece of damper data that's pretty consistent with what Matt and Eric have said..... Over the past few seasons, I have been flying modified MA Tempest FAI heads with large amounts of delta and higher than normal flybar ratios. One of the things that the increased delta does is to really leverage the blade axle in the lead lag direction. When I was running a more radical set up in the 2004 season, I had to use double 50D orings to avoid mast bumping. I went through orings pretty quickly (about once every case or few of fuel - and I know of no FAI pilot that has changed them out every 1-3 flights) because the blade axle was moving so much in the head. I even had impact ovaling in the head block I used where the axle was banging in the lag position. I've since moved to a less radical set up to avoid this issue, but even when the axle was moving around so much AND I was doing our B schedule which has negative maneuvers including a flip with tight, full fore cyclic and lots of negative, the axle never touched the bottom/top of the head block. As soft as we sometimes run our heads, if soft dampening was an easy way to in/produce boom strikes, the sky would have rained F3C models for the past several years of this schedule rotation, and it would REALLY be doing it now with the 2006 maneuvers with which we're working.

Henry,

Most of the post have been very constructive with trying to troubleshoot what actually happened.


Matt

[H to the C]

The issue should be between MinAir and Bobby. All of this back and forth stuff is getting nowhere. Even if some of you are trying to help.

Henry,

If nobody stood up for what was right, and tried to get good information out there, this would be Runryder all over again. Subtract all the drama from this post.... myself, Larson, Russ McC, Jerry, and many others have been trying to help.

If you want to talk more about this, lets take this kind of business offline and keep it between you and I.
