It's not the newer (V2) re-designed one with SAFE technology, rather the original one (V1) from 2008. It seems to be in really good shape considering how old it could be. Just the plane and a battery - no transmitter or charger.

The plane has:
  • Stock BL15 outrunner, 840kV motor
  • 30A ESC with 0.7A switching BEC
  • AR500 DSM2 5-Ch receiver
  • 3x 13g metal gear servos (ailerons & elevator)
  • 1x 37g standard servo (rudder & nose gear)
The battery included in the deal is a 3200mAh 3S 11.1V 15C Li-Po.

Everything appears to be in working order. I'll be using one of my DX6i's (or both for buddy boxing).

I've got a bunch of 3S 2200 lipos (with XT-60s) so I'll be using those (with XT-60 to EC3 adapters) along with the 3200 battery included in the sale. It's great having the same batteries for my 450 helicopters, my Flyzone Sensei, and now the E-Flite Apprentice.

I've heard that the AR500 was prone to brown outs, the stock motor's base (made of a plastic like material) can get hot and melt, and the main shaft can get knocked out of alignment easily due to the motor's plastic-like features. I also realize the ESC has a rather weak BEC (700mA). And the wheels are small - not good for grass at all - thus the prop is only about an inch from the ground. All things that I'll keep an eye on for sure. But this plane has obviously been flow at least a few times successfully, so I'm not overly worried about the above issues at this time. To be honest, the rubber...Continue Reading
