Hello All

I am nearing the end of the build of my Raptor 50 All through the build I have been trying to decide where to mount my rudder servo. I have the choice of leaving it up front in the standard position, but i am worried about the linkage rod join coming apart, or I can mount it on the boom (where I worried about my nice 9254 getting damaged in the inevitable crash

I would be interested to hear where you have yours, and the pros and cons for each

Thanks
Russell

I have my 9253 on the tail, but the more I crash the more I think it should be up front. If you are worried about the connection coming apart, just use some blue loctite and check it before flight. That should be something that is in the pre-flight check. I have read you get better response with it on the tail, but I don't see a difference.

decisions decisions! Had it up the front on my raptor 60 until the joiner came apart, then i hit the ground tail first and the wire push rod wrapped itself around the head destroying must of the parts on the head.
Been using the servo on the tail for about two years now, I've had the carbon rod come unstuck once managed to save the heli, Broken two sets of gears, the lugs off of one case and burned out a jr2700 and futaba 9251.

Even with a front mounted servo all the above can happen,But it does stay oil free.You've seen my raptors hit the ground and they don't kiss it nicely. Its up to you there are good points and bad where ever you put it.

hey
from my experience and what i've seen in other posts...there is no performance difference if you have it set up right
you are worreid about it coming apart but that is well designed and if you put loctight on it then it's foolproof...kinda
i personallly have mine up front becausei strongly believe that in a crash it is like 60% LESS likely to be damaged....jsut my 2 cents
i don't nkow if you knew this either but a 9254 you can buy gear sets for and replace them....if that's whats wrong when you crash...for like under $10
rick's has them pretty sure

Let me know

Thanks

Mine is up front. I need it there for balance. Even had to add some lead in order to have a neutral with fuel.

I personally like the carbon rod and the servo on the tail. I have over 200 flights and as long as you wipe the oil off and keep your machine clean the oil is not a factor. But if you leave it dripping with oil then the front is the better choice.

Knock on wood I have never had a issue with the 9253 or 9254 on the tail, but I have never has a tail first crash either.

Just my 2 cents..... Have fun and fly alot.

I prefer tail mounted
Advantages:
Simple direct routing
Less friction than with the rod and the three rings on the tail boom
When you adjust the belt, it doesn't disturb the tail adjustment. (Quick UK style mount - which I recommend)

Disadvantages:
Can be in the path of oil, but as stated by another poster, if you are reasonable about cleaning after flying I personally don't see a problem
Can dversely affect balance.


In either location, in a crash you can break the gear set and/or the case. Both are inexpensive <$10 to fix.

That doesn't happen of you locktite (only need the blue stuff) and ensure there's no binding. Also make sure that you glue the plastic guides to the tail boom; if you don't they move and cause the rod to flex and bind.

My preference for location is inside where it's protected a little from oil and crash. After around 70 flights no problems at all here.

Buy a bigger battery, at least then you're getting something for the extra weight!

If your worried about oil on tail servo you could always wrap it in electrical tape or get some heat shrink and get that round the servo...the biggest advantage of tail mount servo is getting rid of those horrible white hoops!

I still have my hoops on. I've got the QuickUK tail mount on my 50v2. It's mounted at the front of the tail, so I still kept the hoops.

I'm so tight I've got skiddies in my undies!

Carbon pushrod? Don't forget it's me who can't fly the thing straight - the pushrod is merely an accomplice!

agree with carbon rod most direct, strongest application tt makes a nice carbon bracket that mounts at the back of the output area that comes with the SE kits I imagine it could be purchased separately, check helikraft, oil not an issue if ship is maintained, good luck

LOL. I'd argue with that if it wasn't true.
