Help!
headspeed

I'm setting up my raptor 50 for the md500 body, after upgradeing from the30. Should the head speed be lower for a more scale affect? And if so how will it affect flight, I'd like to be prepared if possible for any major changes. Thanks!

5 blade setup ?
Remember that the more blades the lower the head speed needed.

I am making a ECO8 MD500D four blade setup and will be shooting for a head speed of 900-1000 rpm

Since nobody makes a 5 blade setup for the ECO8

If you're still using the 2 bladed Raptor rotor, then fly with a headspeed that you and the heli are comfortable with. Unless you go multi-blade then it's more important to retain control of the heli with a nice fuse on it

1800 or so is a good mix of stability and fuel economy. Considering a full scale turns 200 rpm or so you aren't going to get a "scale" rotor speed so you are more concerned with the head not shaking.

I also replaced the hard 3d dampeners in mine with blue and the green paddles with black to get a nice smooth scale flight regime.

Thank's for the advice guy's. Ya'll have been very helpful in the short time I've been a member.
By the way it's still 2 blades,I like between1600 and1700rpm at or around hover. And have the blue dampeners with black paddles.Of coarse this will be my first with a body so all of the above is subject to change.

Here' you go, this one turns a little under 1000 rpm on 1050mm blades.

I fly my Raptor 50/ MD500 at 1800 on the 'optional' gearing with an OS 50-Hyper. Most of my flying is done at 5000ft. You should be fine at 1700, just make sure you don't get out of the efficient range of your engine, or you may end up with overheating issues.
