I think I've figured out how to mount the receiver and gyro inside the frame. Remove the gyro tray, mount the receiver inside the frame under the tail boom mount and put the gyro on the bottom plate directly under it.

I had a couple of flights with my 450 Pro 3GY yesterday, and I have to say it flew pretty well. I increased the collective pitch to 12.5 degrees and set the cyclic gains to 3 o'clock. Tail stop is also good now with the CCW brake set to 2. Time to start upping the cyclic rates and I will probably take collective pitch to 13 degrees.

I still haven't tried different blades yet. I must do that...

I'm running some carbonfiber 335mm 3D blades from Hobbyking ($6?).They work pretty good and I have on order some Tarot fbl blades to try.I have noticed that the Hobbyking blades are inconsistent in sets for equal flex and that has got to be a problem.Whats everyone running and what's the best bang for the buck in mainblades??

On the 450's I've been using Align's 325D 3G blades (I got a few sets for $12) and the ALZRC 325mm FB blades. Currently I'm running a cheap set of eBay 325mm CF blades on the heli with the 3GY.

I have been running cheap fiberglass blades from ebay as well without issues. I also recently bought 3 sets of carbon blades from hobbycool. Will try those soon as well.

KST servos and the G31

I've decided to go back to the starting point with the servos. I've ordered a set of the KST215MG servos and hopefully should get them next week. The Robird setup videos show them being used and I've spoken with Liu from Robird and he also recommended them. KST servos aren't a brand that I've seen here in the US so if any of you guys have had experience with them I'd appreciate hearing about it. Also, if you've used them with the Robird G31 I'm REALLY interested in your comments. Thx........

I'm getting ready to install the Robird with a DFC head on my 450. Has anyone compared the manuals for the Robird, ALZRC and Black Widow? At first glance, it looks like the BW manual is going to be most helpful and the smoothest read. I'm assuming they're all interchangable?

I'm using the Kst 215, awesome servo at 7v and my servo arms are at 10mm.Also using it for a tail servo and also awesome!!I had a crash that broke two servo arms but no servo damage( still very smooth).I have been using Kst servos for the last 6 months and while some early batches had some weak main shafts the current ones are good.Alofthobbies sells them for $26 and $1.50 for spare arms or $6 for gear sets.There the least expensive and in the USA!I'm running the Align Dfc head in my Beam and that's why I run 10mm on servo arms(12.5 works to but it feels more solid at 10mm)!

I don't have a DFC head (yet) but I've heard they put more strain on the servos and the rotorhead arm bearings. I'm encouraged to hear that the KSTs hold up on the DFC. I can remember - are you using the Robird/ALZRC fbl controller? I will check out the Alofthobbies website, thanks for pointing that one out.

Two Robirds, one on a Beam with 215 and a Copterx BlackAngel with 115's.Both work great but the 215's at 7v are noticablely faster.

Aloft is almost in my backyard, maybe 40 miles north of San Diego. Thanks for the tip!

The DFC 600 blade grip arms were also exploding till Align issued a fix.

I used to worry about the Dfc breaking but after over 100 flights on each Dfc head( 1 Align Dfc, 1 Tarot Dfc 450)and no play any where I think the 450 version is ok.I do notice spool down vibs but I think that is because I run the blades tighter with the Dfc heads( seems to work better).
