i have a 401 gyro on my blade400 and when i power it up it will not inishalize but if i power it down and then power it back up it will inishalize what do you think would cause this? it happens every time i go to fly! but will allways inishalize on the 2nd power up? and works great after it is inishalized! i'm lost plzz. help??

If its a DX system put the gyro switch in heading hold and rebind the reciever.

yes, i use a dx6i , ar6200 , 401 , phoenx 35, 3= 65mg's , and a s9650 powerd by a evo 25

so i should put my heading hold on and then rebind my reciever? THANKS for your help BarracudaHockey

When I don't have my gyro switch in HH mode when I plug in the battery it will never go to HH mode. But when the switch is in HH mode then plug the battery it goes to HH mode every time. You can also try switching between HH and rate mode three times in three seconds. That seems to work sometimes.

It has to be initialized in heading hold or as you said, it will never go into heading hold.

Whats happening is that the gyro is booting faster than the receiver

Binding sets fail safes. During boot up, before the reciever and transmitter connect the reciever sends fail safe position to the servos (and gyro gain wire). So if you set that failsafe to heading hold, thats what it will get during boot up.

If it comes up in rate mode and you disconnect and reconnect the battery, the reciever goes into quick connect and gets the proper signal before the gyro initializes and it looks like that fixed it.
