Well I got the new one, and here's a couple of pictures in case anyone is watching.
Running a Turnigy 1400kv motor, 8x4 prop with a 1000mah (2200mah shown) battery. I've just been testing it with my watt-meter and it runs at about 330watts when the battery is fully charged.
Didn't expect that much grunt! Just by holding it upright and pushing the throttle up it can easily hold itself in the air from about half throttle. Wondering how it'll be balanced though with a 2200mah battery up front as I can't see any Centre of Gravity markers on the wings.
Also managed to setup my controller so that I have switches for exponential on the throttle, rudder, ailerons and elevators. I'm not sure how much to go with on that front but will get rid of most of the input to keep it safe and then see how it flies.
Gonna give it a go tonight but it is a little blustery so no doubt I'll come back with a bag of foam bits.
From that second photo you can see that I stacked it yesterday and the carbon fibre rods already need setting back in with glue.
The battery has been made to fit by heating up a screwdriver with a creme-brulee blow torch (classy) and then just cutting out the foam when it's red hot. Came out nicely. The fumes that come off that foam though... had a lungful by mistake, not good.
