That is the plan anyway. Only did one 1mm slice so far. Too many other projects. And still breaking in the main gear as it is tighter against the larger pinion gear.

Last time I tried same thing using a stock V911 motor. Trimmed about 3mm off main blade trailing edges and it just barely flew.

My flights get real sloppy on high rates and I can't control the V911. My thumbs do the flying, even in the dark by memory. It's automatic.

Maybe stiffen your flybar some. I like the braided fishing line and CA glue stock flybar I modded. Has some flex but have yet to have a strike.

I think the heat-shrink that MOK used is probably stiffer, but I remember him saying you have to be careful cause of the heat can mess up the ball link ends on the flybar (could warp the flybar too I would guess). The paddle one I did, I did heat-shrink off the flybar until it would barely slide over the flybar then I glued it on. But it broke at the edge.

If you use a CF FB, you may want to do fishing line like I did part way out and glue a small piece of CF stock on the top center (or just that part maybe). cause it was posted a few pages back that the CF FB was weak between the mounting hole and ball link ends and my mod wouldn't help that. I think MOK broke a CF FB too.

I would like to have a flybar with metal ends so I could screw the 4g6 paddles on and be able to adjust them easily to tune in. I didn't like the one shot glue on deal. I have many pieces of stock and various parts to order for some testing I want to do. My main V911 is having trouble that I am going to ask about later.

Thanks. I am sure you will update us on how it goes Is that motor any better not thinking about the gear or about the same? I sometimes get a little sloppy myself on high rates when I go a little "nuts". I get going fast sometimes making maneuvers and the heli starts to get sideways unintentionally and crashes into the ground going down and sideways at an angle.

My v911 is coming in the mail Thursday, I am excited to join the conversation as I test this thing out. I currently own a s107 (with a dead battery that I need to replace), a JXD 340 Drift King (that I like but the gear for the upper blades keeps slipping so I am annoyed with it) and a falcon 40 v2 (that I can't fly for anything and sits on a shelf awaiting repairs). I am hoping to learn a lot about 4 ch flying from my v911 before trying out the falcon 40 again. I must have read a hundred pages of this post waiting for my new heli to come.

I did a while back, no problems with the stock TX. I really bought the 9X because of my 9958's. They're a little beast that has to be tamed next to the V911.

The plastic for the flybar is really flexible so I'm afraid I'm going to break it while I monkey with it.

I did an initial test with the flybar (unglued so I just hovered--and I wore safety glasses!!!) and I could hover pretty well so I guess I kind of got it on straight. I tried monkeying with it some more after that and messed it up so I've pulled the paddles off to try again.

Still though, not too bad.

MassiveOverkill, I had a question for you regarding the SoloPro CF flybar. On your blog, you attached the paddles to the CF bar but how did you do that? I only have the MSR paddles but not the MSR Xtreme flybar so I don't have any of the mounting hardware (if any) that came with it. I don't see how to mount the MSR paddles to the SP flybar. Any advice?
I have an xtreme cf fb and a sp fb and the paddles are just tightened down with the screws on the paddles. Should be glued I guess but I didn't make them. They came with three used v911's I bought. The longer xtreme cf fb is much nicer to fly than the short cut off sp fb, but I still prefer the weighted fb. Even more a cf weighted fb because you lose the flimsiness of the stock.

Welcome to the V911 addiction. "Hi my name is Charles and I am addicted to the V911 heli"......."I find myself craving my heli when I haven't had my fix yet for the day" "I sometimes get so high with my heli and don't pay attention to nothing else"

Great you've been reading up, there are many people to ask stuff on here as well

You can screw the paddles on the CF FB without damage, right? I tried on the stock with the 4g6 paddles and couldn't get them tight enough without squishing the flybar. Guess I could have sanded the FB some and then coated it in epoxy on the end, then sanded it some more and THEN screwed them on, but would rather buy the CF one, lol.

LOL. True. I also recommend the MSR flybar as a replacement for the stock 9958 flybar. Makes mine fly more like my MSR--less "sliding" around corners. Plus there's no #$^@%$ gluing and balancing. It just drops in...

I'm all about the paddles tonight. I went ahead and re-did the paddles on my V911. I tried shoving it in there as far as I could and then balancing them and making sure the paddles track in the same plane. Then once it was balanced and looking straight, I smeared CA glue (gel) around the outside of the shaft and the paddle. I have NO idea whether this will hold or whether I'll have a flybar paddle "missile" shooting off later...

The problem is that when you stick those paddles in there, they're really stiff and hard to adjust. If I had CA glue in there trying to set, I'm sure I'd get it all over my fingers and it would probably harden before I got the darned paddles leveled out. The only way I could see of doing it differently is if I took some sandpaper to the ends of the flybar to shrink it down or else took increasingly larger drillbits to the inside of the flybar paddle with a pin-vice until I got the holes large enough for the shaft to fit in there comfortably. Then I suppose I could balance them and then mark where they're supposed to go, pull the paddles off, add a little glue, and then push them back on until they line up again and HOPE I GOT IT RIGHT!!!

Well, I bought two sets of the paddles and 4 come in a pack so I can experiment. I've got a few more flybars coming as well in the mail so I'll be able to experiment some more. Anyway, here are some pix of my flybar with the CA gel on the outside waiting to cure.

I bought a new leftover MSR a few weeks ago and it came with an extra flybar. I'm gonna drop it in one of the 9958's and see what happens.

Just remember to start off easy with small stick motions until you get used to the way it flies. It'll be a little different. You flying with stock TX or T9x?

You need to sand down the flybar shaft after clipping the weights off. The hold-down screws of the paddles secured it but it wasn't as tight as on the stock flybar. Carbon fiber doesn't have enough friction and the blades can turn on you, especially in a crash, but then again I guess it's better for the paddles to turn in a crash than transmit the shock to the fragile carbon flybar.

I won't mess with the Xtreme flybar until they make it a solid piece all the way through. I'm pretty happy with the stock with paddles, but I do see an advantage to the Helios, as the paddles should be out a litte further giving more leverage. I still have 2 or 3 spares which are collecting dust.

I found no need to CA my paddles on. With the set screw cranked down, they're solid in place. Once again, you want to sand down your stock flybar just enough so that there's a slight interference fit. Don't try drilling out the holes in the paddles, sand down the stock flybar.

I put my 4g6 paddles where I wanted them, then marked them with a superfine marker. Then I put glue inside them and put them on via the marks. I was not sure if it would harden on me too fast and I just barely got it! I wear gloves when using glue anyway. I have boxes of Harbor Freight gloves from cheaper to thicker ones that cost more. I had drilled out my paddle ends (brass I think on the paddles I had) and also sanded the flybar end just a tiny bit.

I want to get some slower drying CA glue for certain things though! That would be much better. also added glue inside the screw hole on mine and filled that area up as well.

Looks good though. Hope you don't get too much FB flex. if so do the small braided fishing line like I did, it helps allot. Just add a tiny dab of glue, glue an end on where you want to start. then wrap it tightly (isnt hard at all) and glue the end when your done. Then go back and brush CA glue around all sides of the line, I did 2 coats. check for balance again though.

Post some flight vids if you can once you get used to it some. I would like to see some slow movements, hover etc. if you can sometime.

I thought you was. But didn't think you could screw paddles on the stock. didnt work for me. It chewed the flybar end so bad, I could adjust it anymore for further testing. I had different paddles, but still. Wonder what I am doing wrong? Do you get less FB flex with paddles as compared to the stock with weights?

Coaxials fly well close to the ground.

V911 has to get to eye level quickly to get out of ground effect. Take it easy on your batteries for the first dozen flights. Do not keep flying until it can't lift off. Swap batteries instead.

Outside summer heat is a battery killer, though the same batteries seem to recover fine on cooler days.

Have fun bouncing the V911 off the walls and ceiling indoors. It won't break until you learn to fly fast. Get some flybars for that time.
