RE: Second plane
G'day
I recently built an E-Flite Pulse 25XL. And if you are looking for an electric to follow as your second plane, this is worth a look. It is easier to fly than my Four Star 40, flies better aerobatics and the kit was extremely well put together.
I put the recommended L-Flite 25 motor in it with a 40 Ampere ESC I just happened to have and a Tunnigy 40C 11.1 Volt (three cell) 3000 mAh battery. I used E-Flite's recommended motor because I knew it would fit easily (it did) and it is powerful enough. There is a larger 32 option but it is not necessary for the way I want to fly it.
It was not cheap (nothing RC is here in Australia) but it was certainly worth it. And as I said before, it flies better than the Four Star 40 and also the Mid Star.
There are also the larger Pulses from H9 which you could also convert to E power.

PS I started typing this before your last post so to some extent it is redundant. But then again, it may be worth a look and think. I suspect the Four Star 20 and the Pulse 25 are similar.
