It just doesn't seem like the brushed motor has enough power to climb higher than 20-30 feet in the air. This is with the stock prop, but I just fit an APC 6x4 on there so I'll see if that makes a difference. I had to cut out a small chunk on top of the empennage for the 6x4 to fit, I hope that doesn't cause any problems.
I already have this voltage sensor to check the battery after a flight: http://www.hobbyking.com/hobbyking/s...dproduct=22693
, but I'm not sure if I should get the FrSky DHT-U or the Quanum telemetry system. I can't tell if the DHT-U has all the parts I would need to see my battery voltage, or if you have to get a separate transmitter. Any help would be appreciated.
Hobby King has a number of voltage meters. This one has not only a read out but an alarm to let you know when the battery goes below a set value. Unless there is a lot of noise in the area you can hear the alarm while the plane is still pretty high up.
I just realized it is back-ordered. I know that other RC suppliers have similar items that will give you a pretty loud alarm when the batteries go low.
