Trex 450 Pro

Hello to all

I am new to helicopters and predicably I have made some mistakes that have led me to email the experts.

1/ After a minor take off accident i damaged the gears that drive the rear tail rotor. These parts were easy to get and fit and after a test run the helicopter was ready to go.

2/ I then mistakenly left the helicopter battery connected and proceeded to surf the controller a Radio Link T6EHP-E just to see what features it had. Following the manual I pushed together the data input buttons in to open the menu to view the screens such as REVR, EPA, TRIM and N-TH by pressing the select button. During selection of the features the helicopter powered up itself instantly to 100% which then led to another crash. This time the main drive gear stripped which again was easy to get and fit. Hoping all was ok i installed the battery, turned on the controller but unfortunately I now cannot function the throttle and the throttle hold switch does not work.

3/ I have attempted to follow the setup to ensure all is back to original including the REST data reset function and I did discover that the STICK setting was on mode 1 instead of the standard mode 2, I then put it back into mode 2 but this did not assist.

4/ The helicopter will go through a series of beeps and tunes once powered up and last night just like the original incident the beeps went to constant beep and then powered up to 100%.

I hope you can assist me as I am lost to sort this matter out, i bet it is a simple thing.

Thank you for your assistance on advance

It sounds like the ESC is going in to setup mode, which it will do if the throttle is up when you plug in the battery. Try reversing the throttle channel.
