Well guys I said the heck with it today and did some circuts around the feild.
I burnt 2 and 3/4 tanks of fuel flying around the feild doing laps both ways and landing approaches and a few landings to check for fuel. Well on the 3rd tank I got a bit cocky and was doing stall turns(for the first time) the got really cocky and tried a few loops. Well all was going great, accually made 4-5 loops and then it happened..... the tail came off in mid air and it went to the ground in a hurry.
Im not really totaly sure what happened, but it stopped forward movement at the top of a loop and when I pushed the stick forward and bit(I think, may have jurked it back for a sec first though) I heard a SMACK and it started to spin without control of the tail. I got it back over to the upright position and it hit the ground just a moment later.
The damage dont look to bad at the first go over, basic crash kit plus a tail gear box.
I dont know if I should be upset or not, I dont really feel all to bad about it, I knew it would happen sometime. Im more hyped about the awsome feeling of being able to really fly it. I had such a great time flying around and hearing the sound of the blades thump through the air knowing I was finally in control and not chaseing it.


Sorry Im not able to post pics, but if some can, I would be glad to e-mail 'em to some one that can post 'em for me,just send me an e-mail.

Did you have a boom strike in the air? Or, did the tail gear box just come off all by its lonesome?

After chating with a couple of guys, looks like I didnt have the mains tight enough and one folded and struck the boom. I haave most of the parts on the way, still in need of a tail gear box case though.

How high was it up when this happend? Seems you got off pretty lightly mid air boom strike and subsequent crash. My first crash cost me a set of main frames too.

rcspud, Too bad about your Raptor. It looks just like mine after a hovering incident last weekend. I was doing O.K. then a I got a little too high and a little too quick on the pitch. I sraightened the boom supports they looked like bannanas. I had some parts but of course not all of them. I think I need another whole heli just in case. DOC

Hi, Do the factory dampeners make the head loose and make it possible for a boom strike in inverted looping?

No the factory flap damper will not make the head loose. The reason he had a mid air strike is that the blades were not tight enough in the blade grips. This allows the blades to dip too much on the lag stage and contact the boom under stress, or quick movement of the cyclic.
Keep in mind that you have a lead and lag blade at all times with that main rotor spinning. That is why airwolf (the movie) is such a joke.......A supersonic Heli? How does the lag blade go into negative supersonic while the lead blade is supersonic? Come on all you engineers out there educate me!....

Keep your blades tight in the grips and this won't happen to you.

As for the flap dampers they do sell various durometer hardness of rubber for you to choose from. Stay with the softer ones if you get too hard of a durometer it is harder to keep the blades in track. Also keep the spindle that runs through the dampers lubricated with dielectric grease. This will help keep the blades tracking good.
