Well I did it and turned mine into a lawn dart!

LMAO Just meet up with a cool local, that knows how to build and fly...unlike me!! So we did some hovers in the yard, then headed to the field! Wind was mild for my taste 5+ or so, so I took off. I did a nice turn on the right came around and tried to go left. I got so far then everything just went straight towards the ground ( like it locked up). Opps! So I did buy a lawn dart! Thanks LockMD I had a good time and now I have a reason to tell the wife why I need to upgrade all servos, gyros, carbon fiber, esc, motor, camera, and parts for my computer cause she won't know the diff!!! Well its all fun and games until I hit the shop. Looks like I might be working more hours this week! Next time I might just do the lawn dart just be cause that was cool as *****!!!!

:hug:I'll be glad when they have RTF 400 airframes (minus the batteries and TX) I'm going to get several of them. Last I Checked you still had to buy the whole works. If you had that kind of luck try putting a different brand of servos. I've stripped out two already, got two spares.Learned how to straighten the main shaft with it still on the heli. Do it on the cx2 every week or two.

How do you straighten the shaft out on the heli? Share that one with a newbie please. I can't even tell if I have bent one unless it's extreme. I think it makes more differenece in which direction you tighten the main shaft gear onto the shaft flats. (Could be changed 180) Ditto with the outer shaft and the set screw hole.

Yes how DO you straighten it ON the bird? I would love ot know :)

Sorry its taken so long to reply, I've been moving. Spin the helis up as slow as it will comfortably go and observe the anti-rotation bracket ( see horizon hobby parts list). If the anti-rotation pin is thrusting in and out of the bracket (assuming all is well balanced) then the mainshaft is bent, uasually at where the shaft comes out the top of the heli, since that is where the most leverage is applied in a blade strike. Stop the heli, unplug the battery. By hand turn the rotor shaft till the anti-rotation pin thrusts as far into the bracket as it will go and stop. Hook a forefinger over the rotor head and placing the end of your thumb with one hand onto where you observe where the bend is and holding the tail boom with the other hand, firmly and smoothly apply reverse pressure where the bend is on the main shaft being careful not to break any linkage (with aluminum upgrades you will likely bend the upgrades negating the repair into a worse condition, keep the plastic on).Alternatley spin the rotor and bend the shaft until the anti-rotation pin stops (0r a tolerable level) thrusting into the bracket. Then the shaft is straight. Beats taking apart a Chinese-puzzle you can't put back together. YEEGADS!!! Try practicing on a wire coat hanger if you don't have a cx2.

Put a carbon fiber upper rotor shaft aquired from scrap (check your LHS) on my cx2, no more bent shafts, when the time comes to disassemble my b-400 I'll see what I can do about CFing its shaft. (See the thread "balancing xtreme blades")

Replacement main shafts for the b400 are only 2 bucks and look easier to replace than the CX2, will stay with the stock ones for now, may fill shafts with JB WELD if inspired to do it just to experiment.
