Been looking at some Lipo's for this bird.
Since it's a racer and it only needs about 120 seconds of full power carrying any more than enough to do that plus enough to putt around for another min at 1.4 throttle waiting to land is a bit of a waste and a extra weight as well.

I decided to change the colour scheme to make it similar to my other planes Here's a pic of the progress so far.
I was quite suprised at the weight difference in the covering I'm using and the original Eflight covering. After weighing it I reckon I've saved about 1/4 of an Oz by re covering it.
