I brought home the XeroG raptor to start trouble-shooting again. My brother is feeling good, his trex-600 showed up yesterday and it is almost ready to fly this evening... need to instal the radio gear and a couple of links, setup the pitch and give her a try. I would have worked on the raptor but we decided to get the 'rex up and running first so we would have a heli for him to fly while figuring this one out.

I tried the rotor head assembly from the XeroG raptor in my stock raptor frame today and it worked very well. No hint of vibrations. I could not use the swash off the XeroG setup without adding an anti-rotation pin so I used my stock swash. The swash on the XeroG setup was just replaced with a new one and it did not help reduce the viberations any.
here is a picture of the XeroG raptor on the left without the canopy. The stock eRaptor is in the middle with the blinged rotor head setup on it. The c50-15xl mounted in the box is setting in between the two. It is removed for now because I bought a used actro 24-4 to try on the XeroG setup. The used actro appears to have been in a crash as it seems to be bent. (it vibrates the heli frame pretty bad when running.) So I will mount the hacker motor with the box again to continue testing but what else is there to test? any more suggestions are welcome.

MR. Snoopy!

There is nothing that is XeroG which can cause this vibration, most of what we manufacture is non-rotational except for the swashplate and our gear reduction unit. Since you are using a V2 box and a OEM swash, I cant suggest that there is anything wrong with these parts and in addition would suspect not.

All that being said, a vibration can be frustrating so here it goes with the usual suspects. Since you have tested the rotor head on your other machine we can rule out dampers, flybar mismeasurement, bent spindle and finally the rotor blades? Did you test using the same ones, blades can be really far out even though they "come balanced from the box?"

The next area I suspect is the tail blades, tail output shaft, and then finally the bearings. The bearings can cause slight vibrations but should not be enough to cause a bad day.

And finally main shaft?????

I am sure you have tried and checked just about everything....?

Let us know what you have done and we will try to point you in the right direction.

Hi XeroG! Thanks for the input. The head assembly that I swapped from the XeroG to my stock raptor has a new feathering shaft, main shaft and metal head. At the same time we put new main bearings in the XeroG frame and also tried a new swashplate. I bought stock plastic 85mm tail blades today to try. The ones we have on the heli right now are the TT 95mm cf blades. My stock rappy is using the stock plastic 85mm tail blades.

Two area's that I am wondering about (assuming that the tail is not the problem) are the main bearing blocks and or the lack of a anti-rotation pin/slot. I don't know if using the elevator control as an anti-rotation system works as well or not. Nor do I know if that could contribute to the head wobble we are experiencing. Is there any chance that the main bearing blocks could contribute to the head wobble because of a slightly loose fit of the main bearings? The fit right now seems reasonably snug but it is not difficult to slide the main bearings in and out.

I have two more sets of main blades to try. Both have been tried on the XeroG setup and they both acted about the same. The head started to wobble approaching 1900rpm. The 600mm funkey blades I have used on my stock raptor with no vibration problems noted. The other set we are using on the ZeroG are another set of 600mm TT cf blades.

When I get some more time to work on the XeroG setup I will try another motor shaft on the actro24-4 to see if that was all that was bent. If it runs smooth I will use it for further testing as this is the setup I am using in my stock raptor with good results. If I can't get the actro running correctly then I will remount the hacker/box setup and continue trouble-shooting from there.

Thank you for your time and help.

Charlie

actro 24-5, schulze 32.55, 11s evo 20's 3700 mah 6min in idle up 2.
i put back 2800 mah after that flight. i fly it in 1 tho and i think i could get more from it but thats all my nerves can take at once.
i'm going to put a 24-4 in it this weekend with a smaller pinion and see what that does to amp draw and flight times.

for now check tppacks.com. Soon you will be able to purchase the new e620se frame to convert your .50 raptor to the new eRaptor from Thunder Tiger. tppacks.com should have those available online shortly.
