The last 2 flying days I have flown the XT 25e and been very happy with it.
The ZOHD Kopilot is only needed for RTH (I’ve had to use it a couple of times already as the predominantly yellow plane disappears the moment you take your eyes off it) . The ZOHD Kopilot also has a built in switchable stabiliser that make landing in the wind a tad easier but you don’t really need is as the plane has that good “locked in” feel about it.
Today the new 12 x 8e APC prop turned up (this is the recommended size but I have been running an 11 x 8e as it was all I had) so it has been fitted ready for another test flight.
I have also ordered a 4200mAh 3S 75C LiPo as the current ones I have – 3000mAh 3S 30C LiPo’s trigger the low voltage telemetry back to the radio very quickly at WOT. Back the power off and at least 10 minutes of flight is achievable. Testing this morning shows the motor draws 8 amps more with the larger prop so I think the larger capacity battery will be needed.
For those that are interested here are the test results with the two props, both tested on a fully charged battery.
