The Elite 1500 are a little bit different than the Eflight's. I believe they are still NiMH. For the team's first prototype flight this year, we did cheat a little bit and used LiPo's.
Which brings be to our team's first milestone: We got our first flight on Sunday!
Although our plane doesn't look very pretty yet, I will post pictures soon. Hopefully after putting this one through some brutal testing the second prototype will look more like a plane.
