Sorry to hear about your bad experience. We have identified an issue with the on/off switch on a small percentage of SmartPlanes sent to North America. We are currently offering unlimited refund or replacement for any SmartPlanes from the affected batch whose on/off switch breaks during normal use.

Hi Karl, that's interesting. I think the weight-balancing or physical trimming has become deformed due to hits. This usually doesn't happen, and any deformity should be visible. Did you also check that the "Reverse" switch did not accidentally get toggled? Another thing you can check is, hold the phone, give it full throttle (don't let it fly away!) and turn the phone left and right. Does the rudder turn approximately the same angle left as to the right? The wind from the propeller can affect the rudder's turn.

Also, in a week or so we are about to push an app update which has some improvements to FlightAssist, if you cannot solve the problem maybe that will help.

Hi Byron, is your Smartplane turned on and fully charged? Are you keeping the phone very close to (almost touching) the plane?

Galaxy Note 3 is known to have problems with Bluetooth Smart. Please watch out for app updates on the Play Store.
Note also - you cannot use your phone's Bluetooth settings to "pair" with the plane. In fact you don't need to pair - just open the SmartPlane app to connect to the plane.

Please try the latest app update v2.1 on the Google Play store. It should fix this issue.

This can happen due to two reasons -

1. Maybe the rudder got stuck - move it by hand (carefully!) to the left. It should then be OK.
2. The "trim" option somehow got turned on without your knowledge. To check/fix this, press and hold the horizon till the settings/options show up. Then, turn OFF the "Trim" switch.

Does this solve the problem?

Hi Erik, I replied to your review on the Play Store. Can you please try the v2.1 update?

Hi Gowtham, please try the latest updated app v2.1-BETA. Does it solve the problem?

The firmware will be updated automatically, if needed. You don't have to do it yourself. The process takes a few minutes and the app will tell you when it's updating the firmware.
