Dielectric Grease, what is it? help please

[enrico]

Hi everyone,

This is a quickie for everyone, It is about dielectric grease. The raptortechnique web page ans several other forums say that it is nescesary to lube or grease the dampners and that dielectric grease is used for this purpose. After several auto shops asking question, no one could tell me what is dielectric grease so the big question is, what is it? Does it have another name, maybe brands, what is it actually used for? ... Please any help will be very appreciated.

Regards

Enrico

I use the silicone oil that they use in R/C car shocks on my dampners cheap easy to find, just get the thickest they have, lube after every 20 or 30 flights

also you can try plumber supply shops or hardware shops ask for "stop cock valve lube" its the same stuff

Ok. I'm the new guy. Just barely got a Raptor 50 last week and building it. Have flown planes before. I have had some people say you don't need to lube the dampeners and they have never had a problem with doing it that way. Raptortechnique.com says your main blades will go out of track if you don't. Who is right?

[enrico]

Raptortechnique is right, specially when you switch from the blue dampners that come with the kit with the harder ones, the orange dapners. If you dont use any grease the blades will go out of track instantly. I will also recomend you to go for the lube in the dampners. It`ll pay off in the long run!

blades will not go out of track instantly, I use the red dampners and have NEVER had problems with my tracking EVER, even through hard pitch pumps, but I do change my dampners every 3 months regardless, for longevity it is probably advisable to grease them, my helis do see hard work and I maintain them accordingly. Having said that, my little venture 30 which I fly for fun does get the rubbers lubed because I dont do as much work on it as I should

My mistake, I shall correct instantly, but anyhow, when I first put together with the red dampners, at first spool up the blades where completly out of track. I raised head speed and little to no improvement was made. By next weekend I lubed the dapners, whent to try it out again an voula! problem solved. Blades where tracking perfectly with out moving links or anything. Ausheli is right though, for logevity it will also help. Just my two cents.

I don't have radio gear installed yet so the servo links are hanging free. Once I have those installed though, if I have it lubed correctlywhen the blades turn the links should not be sticking or moving right? Swashplate should not be moving up and down. Forgive me if I sound nervous about this. I am. If I crash this thing the first flight the boss is not going to let me get another even though I am having someone else fly it first.

once you get everything hooked up to the servos, they should stay put unless you move the servo arms or if you press on the links. The only parts that should move with out any servo input is the flybar and the short links. Think I got it right, anyone else can chip in and correct me if I`m wrong, please? the best way to go is follow the step by step instructions of raptortechnique. they are quite well detailed and will guide you through the complete building of your R50V2 with out any mess up. (Trust me, Since step one I messed up!! :shock: if it werent for raptortechnique, i wouldn`t have learned anything )
