How do i get the pin out of balance bar assembly. part of the bar broke of in a crash. i have a new bar.

I had a similar issue when my kids mixed rechargeable and regular batteries in the Wii balance board. The acid leaked and the springs corroded. But I figured out a quick fix - see photos. The springs look just like the spring-end of a safety pin, so I just snipped the ends of two safety pins and fixed them in with needle-nose pliers. Safety pins conduct electricity and the fix works fine. Cheers.

you can find replacement balance bars for the Fast Lane Hawk 4 rc helicopter from WAYNENIK on eBay!

Sometimes "toilet bowl effect" or TBE can be caused by a crash.
Try this: Gently, but firmly, press (or pull?) the drive shaft down towards the body, where it comes out of the 'copter, and where it comes out of the bottom rotor and attaches to the top rotor. Also, check for any thing wrapped around the shaft. Even a single long hair or thin thread can wrap dozens of times around the shaft and impede its functionality. Balance bar blade strikes are fairly normal in crashes or out of control flying (i.e. heavy throttle trying to pull out of a drop) and not to be very concerned with, they will decrease as you become an even better pilot.
You say "now, after liftoff it just banks sharply and crashes" does it spin? Or maintain heading and just bank? TBE will often get worse, but can usually be fixed.

Charging/Battery care?
Fly. As soon as you can't keep altitude, land and turn helicopter power off. Do not drain battery fully, ever. Cool for 10 mins. Charge until light on USB charger doesn't get brighter when you unplug heli. Cool for 10 mins again. Rinse and repeat.

Please let me know if none of these solves your issue, and I'll consult my repair notes and pick a few brains, we'll figure this one out for ya!

This is called spring bar or spring pin. You can buy these on ebay. Make sure you get the right size. The distance between watch lugs is the right size. Measurement must be taken in mm.

May I ask what heli you have so I can help you more. I am a r/c heli piolet and know most helis

The top of the main shaft is probably broken. There are 2 pins that hold the "head" for the main blades straight and are probably sheared off. This is causing the balance bar to hit the blades and cause it to crash. You could try the crash kit here: http://www.helipal.com/spare-part_v-max-parts_syma-s107.html

The upper shaft 'T' head has a broken pin in it (the part that holds the blades. You can flip the heli upside down and slightly rotate the blade housing back and forth and IT SHOULDN'T do that. Another way to instantly identify it is dislocate the rotor head links and the upper blade housing should instantly separate) It's made of plastic.

Anyway, It's also called the "T.B.E." Toilet Bowl Effect. It's not 'really' what's taking place, it's move of a cyclic issue but the effect looks like it's swirling in a toilet bowl... You need to replace the inner shaft basically on the upper rotor. They cost anywhere from $4-7.00 bucks. It took me about 2 days of researching and purchasing another one to finally figure it out. There was another website that says the balance bar is it or the gyro has gone bad; this simply isn't true.

Cheers!

Cut the balance bar off until the pins are exposed. Use some pliers and squeeze the pin out and then put the new balance bar back on and put the pin back in.

I did it this way without the tool kit, my balance bar was already broken so it wasn't an issue to cut it. It worked for me, I am flying it right now.

Were you able to find a replacement balance bar? I broke mine and can't find one? Thanks!

Well according to my mitchell manuel you don't have to.here is the procedure.
1. open the hood.
2.Remove the push-pin retainer's that secure the top of the upper facia and grill assembly to the upper tie bar to allow the upper facia and grill assembly to flex forward.
3. remove ther bolt and push-pin retainer that secures the top of the headlight assembly to the upper tie bar.
4. Gently pull the upper facia and grill assembly forward to access the bolt on the inboard side of the headlight assembly
5. Pull the headlamp assembly straight out to disengage the the snap in retainer at the lower outboard back surface of the assembly. Turn the assembly so that the inboard assembly clears the front facia.
6. pull the assembly out and away from the veh.From there you'll be able to access bulbs.
be careful not to touch the bulb with fingers or oil in skin will blow bulb.
Good luck.
