It will be rather small. Go to WalMart, get some ping pong balls, Michael's craft store and get dowels. Make your own. Cheap and easy.

See some I made here. (http://www.helifreak.com/album.php?albumid=567)

Ping pong balls are a tiny bit lighter than woofle (sp) balls.

Also, you do not need tomake a center hub like I did. Just cross them and wire tie them in the middle. Use two, one each way.

Thanks Heli... Appreciate your input.. The set I got was with all the B400 parts at my LHS so I just grabbed it and didn't think about it until I got home.. Thought they looked a bit small. Wife just left for wallmart.. "hey, grab me some ping pong balls.." She looked at me like I was nuts.. Thanks again!

yes this is maybe too short for the b400 but maybe work
i did my own with carbon fiber tubes but so crappy, I didn't fixed them on a centre and didn't cut them so maybe I know why they crashed so much... stupid I am but now this is over for me.
Enjoy your first flights, be gentle with throttle please and stay on the back of the heli.
IF you broke servos gears, change them for metallic such hitec65mg as I crashed 3 of them, eflite servos are so cheap/weak

Did they seem small for your blade or just about right? Looks like you and I are of the same profession.. :thumbup:

i bought 4mm carbon fiber rods. used plastic balls that i had. blue tubing keeps balls from moving to skids, the black things are the clamps that hold training gear on skids of cx2. black electric ties stay on all the time and i just thread carbon fiber rods through them. back side of criss crossed carob fibre rod is some whiteout indicating center.

photos to follow later. sorry

You can see here the ones that i make with 2 carbon rods and the balls of the pack that you mention here. i get those but for me i found them too small so i make this and never crash.<object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/WlCmiMfu1Fk&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><embed src="http://www.youtube.com/v/WlCmiMfu1Fk&hl=en&fs=1" type="application/x-shockwave-flash" allowfullscreen="true" width="425" height="344"></embed></object>

I did the same thing. I had that kit left over from my CX2 so I just cut the rods in half and epoxied them into longer CF rod that I got at the LHS and left the thin rod, rubber grommets and original orange balls in place. Worked great!
