Default RE: Purple Brushless Electric Ultimate BiPe

Well I maidened my little BiPE today.

The battery door is being held by two magnets. The magnets are epoxied into the fuselage, and there is a corresponding washer in the door for each one.

I fashioned a battery tray that goes from the firewall to the area over the wing. This permits me to mount larger batteries lengthwise.

I'm currently running the plane with 2000mAh and 2200mAh batteries that I already had for other planes.

Throws are adjusted beyond the specs. Low rate Expo at 15, high at 30%.

At first I thought that I was having problems getting the C.G. set up properly... the curvature of the wing airfoil caused me to misread the C.G. position as the plane nosed up a bit when held at the location the manual calls for. The airfoil shape caused this not the C.G. position which I had right.

I find the plane rather docile with the above setup and the 9x6E prop. It's not as responsive in rolls as my Ultimate 40S... probably because I am flying it relatively slowly with the 9x6E prop. I may need something larger... but I don't want to burn out the ESC as I'm only using a 15Amp one.

I don't have enough output to hover the plane.

The plane flies nicely though. Not twitchy at all.

Still wish I had gotten the blue one....
