Raptor 50SE build, which dampners, Raptor peeps help if can.

Hey all, building a Raptor 50SE right now. I read an article sometime ago on head dampners and I need to ask a question as it has been some time since reading it and can not remember something. .... With the metal head on the Raptor 50SE some people have stated abit of a head shake on spool up and spooling down after landing at lower rpms. From what I can remember this was with the "RED" firmer dampners that come with the kit that state for "3D". Anyways then of course in the kit you get the "BLUE" dampners which of course are softer.

My concern is this, I do not want to install the blue ones and find out after doing my first flip that I connect the boom and down I go, but then again I do not want to have a twist and shout contest with the red either. Has this issue on these dampners been resolved or have people went to using a different aftermarket dampner made by someone else that is far better? Or am I worrying and talking over nothing and just put in the "RED" ones?

Thanks if you can help as I still need to learn allot of ins and outs on the Raptor heli.

Depends on how hard you fly, rotor rpm and blade stiffness along with tightness in the grips.

All raptor 50s will shake a tad until up to rpm or off the ground. Remember landing gear flexibility matters not in the air. If you fly off grass try the reds. I'd suggest you lubricate the red rubbers and the spindle with silicone grease.

Personally I did not like the reds in flight due to some wobble at certain rpm with shaky stick movements (too much coffee and I'm not about to give it up) and went to V-1 black rubbers stretched over the V2 spindle and compressed into the plastic V-2 head block. Pretty stiff compared to the V-2 blacks. Have not tried the blues in a 50 though but in the 90 they are a bit too soft.

What generally happens with a stiff flap restraint is ground resonance on a hard surface. Same thing with most all 2 blade helicopters.

With my setup I've yet to hit the boom with autos, flips, rolls and inverted loading but my son Colin on the other hand managed to destroy two helis over hundreds of hard flights and so he prpbably should start to use the red rubbers with the 30 and 50 machines.

Sorry I could not help more.

I've flown a friends R50 SE with the blue and red dampers and the red's are quite a bit better IMO. If you're just going to be doing basic stuff for a while (hovering, FF, loops, rolls) use the blue ones, but if you're getting into 3D put the red ones in just make sure you lube the spindle up well.

You can also use V.1 black rubbers in the V.2 head which is inbetween the red and blue dampers..I've managed to hit the boom with this setup...but it took 6 years of trying

Thanks guys, since I am not very likely to do allot of hard 3D this year I put in the Blues to avoid the spoken of head shake. My Bud Willie said the same thing you did Colin on the reds. Thanks to both you and your dad for the replies and details, it is greatly appreciated.
