just checked with graupner.

available from november 15

looks like a good servo, will inform with my supliers overseas..
i am also looking for a none expensive paperweight got one ?

I'll take your first half a dozen at reduced price for putting you onto them!

LOL. Don't take the p1ss too much as it will affect you if I have to keep the paper weight!!

We are a few in Norway that has been using them for the last two years. Guessing about 50-100 servos.
It seems to good be true, but isn't. No issues so far...

It is very slop-free and has has a low buzzing sound under load.
Tested it with an amp meter and under max load (thumb on servo horn) it had about half the current draw compared to a 7955 TG despite the 707 having better holding power in real life...
I have found nothing that seperates this servo from others costing 4-5 times more. The holding power is outstanding. Great flap and rudder servo.

If had to say something negative about it, it has to be that it is not the fastest servo around, but in most jets, you don't need the speed anyway...
I have about 20 of them lying around for future projects. Just mounted the 707 on the rudder, flaps and nosewheel on my new CARF Tutor.

As Staale knows I have tested them too, they seem good, much better than Hitec, but saying nothing (I saw a smoked Hitec on friday in a jet-now with JR 8411)...even CARF are using them in the UF on elevator...no collision avoidance electronics in them though
I won't use them yet in a jet as I don't get a few hundred euros saving for a possible ruined day, in a several thousand euro model.
I've used 8411's for years and years and know where I am.
