On my Electric helis, we always put the Gyro in the back, the Raptor i bought has it up front, on top. I am putting a 401 in place of the Century PG2000 (its for sale in the classifieds)

Whats the best location on one of these puppies? Also the servo is up front to, but has a really nice wire link going to the back....should it stay or go back to the tail? Seems like the removable tail is really nice...hanging a servo on there makes it more difficult to change boom...

Either way... there are pros and cons to each

If you were to put it in the tray... it is protected in a crash and away from the exhaust.
Only bad thing is that some people have had problems with the connector coupling that connects the 2 rods. Just make sure u locktite that part.

If you were to put it in the back... it is more succeptible to exhaust and more vaulernable in a crash. Good thing is... you can install a thick carbon rod that directly donnects to the tail without having to use that coupling.


Either way is ok.

I just built a Raptor 90 SE and i chose to put it inside the radio tray. Just my personal preference.

KK,

The best place to put your gyro on the Rappy is up top behind the main shaft on that little shelf it is way protected there.. Case in point.. I flew my Rappy 50 into Mother earth at balistic speed no damage to gyro at all althought the whole front was destroyed... I flew my R30 into the ground balistic ( well as balistic as a 30 can get) straight backwards tail first, no damage to the gyro even then and that was a crash on concrete.. My buddy had his up front on top of the servo tray part.. thats one dead 401.. it even blew surface mounted parts right off the circuit cards..

Servo location is personal pref.. I have one in back on a CF mount and one in front in the servo tray... I have never had a coupler come loose for the one in front and it has been shoved into the ground a time or two.. and so far luckily have not busted the crap outta the servo on the tail.. As stated above putting a servo on the boom does expose it to some fairly nasty environment.. exhaust, the ground directly lol.. and putting it up front so far has had no ill effects.. I cannot tell the difference in the way the two birds fly so there is no advantage to tail mounted for flight characteristics.. However you can use a CF pushrod if you mount it on the boom.. After mounting mine back there, when I do it again I wont go through the expense of another boom mount no gain and its a bugger to clean... most servos are fuel and moisture resistant so you dont have to worry about the exhaust damaging it so much as its hard to clean under the wheel and around the mounts

I originally put my gyros in the back behind the mast but moved them upfront to try to keep them cleaner. BUT, after losing 2 gyros due to damage from crashes I moved them back to the shelf behind the mast. The first crash was a nose first hit into the ground from about 50 feet and the second was a boom strike on a botched auto, The second minor crash actually caused more damage to the gyro than the first. I believe that after the blade struck the boom and broke it came around and smashed thru the windscreen into the gyro. The first 401 gyro needed a new case and the second was a total write-off (at least that what hobby services said).

As far as the servo goes, put it in its stock location. Boom removal and adjustment takes a bit more but the servo is better protected and will stay out of the oil from the exhaust.

place the gyro behind the rotor so it will be save

as for the tail servo just mount it in the front
but if you realy want a removable tail
make sure it will be easy to do that and with a belt driven tail i think it would be more trouble than easy

just my two cents

Alistair,

I'm pretty sure "unlike yourself" he was just being helpful to a new nitro pilot and emphasizing the importance of locktite in that area... Yourself being of veteran status I would hope that you didn't get there by making a whole lot of posts such as this..

If this is a problem area, I will file a notch in the rod with the dremel for the set screw, and locktight the set screw....

Great tips guys, thanks for the help!!!

hey
i have mine mounted in the back....personally i think they put taht tray right behind the main mast there for a reason....
people think that a direct link from the tail servo is better but if u have it set up right then it can be just as good from the front....
your preference really but just remember price and repair costs are an issue


Let me know


Thanks

I have mine put at the back,behind main shaft on my 2 Raptors 30, 60.

I just found out the Gyro on my Raptor 60 became loose as the 2 side cellotapes was not good enough to hold.

What will happen if I found out it too late? (become too loose while still in the air )

KK,

No reason to file flat spots its a fairly small rod and that would weaken it.. Just as long as you use locktite on the set screws you will be fine.. Mine has never come apart even after ballin it up real fast .. IMPO anyone who has had this come apart hasn't done their daily preflight maintenance. Check it for tight everyday and I am sure you will have no issue with just like myself. Another reason some ppl have had it fail is by not sticking it in all the way.. Ensure both rods are stuck all the way in equally there is plenty of rod thread on the ends for the ball links to accomodate this..

hey umbro
a number of things can happen....i have heard this happen to people and it ain't pretty....
it could either spiral out of control becaseu the gyro would have no componsation and you might just try to auto it down....
hard to explain would have to experience it i mean it's probably different each time!

Let me know


Thanks

nope, i got "here" by telling people like you to piss off... yep the same people that are self proclaimed gods... the same people that defend blah blah blah... the same people that have a stick up their arse and don't have any fun... the same people that take everything much too seriously... the same people the attempt to attack me on here because i say, well that's stupid... of course that should have locktite... and no, not everybody uses locktite there.. i've seen it... they can't figure why it doesn't feel right or respond... not everyone uses locktite on the main blade bolts etc... so it's not that obvious, and the sense here is not that common.

why would you put unlike yourself in quotes? doesn't make any sense...

AND... if you read my post which i'm sure you didn't... you just said oh, here's an arse i'll go get him... 'cause you're a knight in shinning armour and all... i asked a question mate...

so to shorten my response to yours........ piss off

good day

Well said, at least now I can tell why your woman left lmfao.... I wish I could proclaim myself as a god, but have yet to do so. I am learning right along with everyone else here. I was also not protecting anyone, I am sure he can take care of himself. I just enjoy noting when someone is a complete a$$. As far as as taking stuff to seriously maybe but to enjoy myself I don't have to do it at anothers expense.


I am truly sorry you cannot comprehend why I quoted "unlike yourself".

Good day to you

Is there a Nitro Helicopter beginners Guide? I know we have one for electrics....

I for one dont use locktite on the main blade bolts.... there is absolutely no reason since they are nyloc nuts and should be part of your regular flight preventative maintenance to check them. For me if they feel like they are no longer tight(thread gripping wise) I replace them.. I have never had this happen until multiple times of removing them. Real cheap insurance to replace them from time to time.. I am not sure if this is rumor or fact but somewhere I once heard or read that locktite weakens plastic so it would make no sense to put it on bolts that use nuts with nylon inserts in them.

There is a helibook out there that is highly regarded among the members here. It's called "Rays Authoritative Heli Manual" and costs about $22 at heliproz. It has detailed maintenance, learning, and a load of other information in it.

i was stupid enough to use locktite on main rotor bolts
i was stupid enough to use locktite on main rotor bolts and after i checkt the nylon was not gripping the tread so i replace the nuts and did not use locktite this time
so never use locktite on nylon nuts any where on your chopper

if you're looking to bet the piss beat out of you, you come and say that to my face. we'll see what happens then you insubordinant fool. i'll even let you know when i'm in your area.

again, your unlike yourself quote has no relevance what so ever.

i meant main bolt ie, the bolts that hold the grips on, not the bolts that hold the blades themselves in. nylocks and locktite is not a good idea.
