This is the third time I'm going to try to post, seems to keep timing out on me.

I have an e-flight apprentice I've been flying for about a month. Every now and then when I turn the transmitter on, then connect the battery Ihear the start up beeps going, but the plan does not seem to be getting power. Ican hear the low pitch electronic noice coming from the plane, but can't get the prop or servos to engage.

It happened again today after I went to change the lipo battery. When Iplugged it in it was no go.

The manual does not address this issue as far as Ican see. Any idea what I'm doing wrong ?

Thanks

Check to see if it has a safe start. You may need to go to full throttle then back to low in order to arm the system. Other areas to check are the charge on the Lipos. Make sure they are freshly charged to full capacity. If the ESC is set to reduce power when it sences 70% power in the battery then low battery power at the start will cause these type issues.

it the TX bound properly, or somtimes you need to turn the TX on for a few seconds first so it can secure two open channels.
