Spatan USB Link Issue

[KnifeEdge]

Anyone had the problem of being able to read from the gyro but not being able to write?

Any ideas on whats up?????

have you tried deleting/re-loading the drivers?

also make sure your using correct one for your cable type.

Just tried it now... have deleted flash link in devices, installed drivers, plugged in the USB flashlink. Vista then installed its own drivers. Still have the same problem.

Any other things I should try?

[raptorheli2]

do you have another gyro you can try?

want to find where we are chasing a fault here.

cheers

hi thanks for your help!

After my fafing around for a few hours I finally have it sorted. Managed to upload new firmware to the gyro, and it now allows me to read+write config settings to it.

I have removed subtrim on the tx and put it in the config settings in order to get 90deg on the horn.

I am hoping that this may get rid of the drifting! If not I think I will have to play around with mounting.

Cheers

When setting up KnifeEdge dont use trim or you will be causing drift yourself. Also make sure revo mixing is disabelled in the TX.

A far better solution If the servo horn is not 90 deg is to sort this mechanically by moving the Servo horn round on the splines till you get 90deg or use a disc and drill it yourself. Thats why servos have different output arms.

Adding trim creates a cumulative effect whereby each time you switch on the Rx/Gyro it considers the Neutral hover point to be wrong causing it to drift.

Thanks Brian

I have got rid of the subtrim, and have made the mid point adjustment on the gyro using the software. Hopefully this will do the trick!

Thanks
