Chris,

My Aresti is my second plane. I believe you when you say it's stable! I was quite impressed with it's "go where you point it" behaviour and how easy it is to land. It was something getting used to how long it takes this thing to slow down for approaches compared to the trainer.
I've been practicing KE for a while and know that I need to move the CG back some. I expect it will be much livelier after that. Either the metal H9 engine mount has to go or some lead is going in the tail. Currently using an 11x5 to keep the speed down, but thinking it's time to go back to an 11x6. I bought a Saito 72 for it, but am keeping the 46FX on it now that the tower muffler woke it up from it's slumber.
Have you flown a Kyosho Sensation or Majestic 40 size? I have a couple sensations still in the box from the Tower clearance. I'm tempted to get a Majestic (tower please put them on clearance) after reading about how stable they are. On the other hand, I'm thrilled with the Aresti.

swlarcham,

The Tower muffler has the advantage of diverting most of the goop above the wing if you aim the tip up. Just do some upside-down every now and then to clear the goop out.
