Zen 50 or H9 Aresti or GP Venus
It's going to be interesting to see how people like or dislike the Venus. Given GP's track record, it should be a good plane for a daily flier. I would go with either that or the Zen, both look pretty good. The zen has impressed alot of people over its lifespan, while the aresti hasnt been all that stellar.
If my Kyosho Majestic decides to meet the ground, I may try the Venus, just because it's very affordable. The specs are very close to the majestic, but with larger surfaces for F3a stuff, which would save me some time doing the mods. I am running an Enya 80 4stroke on the Majestic, and all up weight should be between 5 and 5 1/4 lbs (prob 5 lbs 2oz max), so I am excited to see it fly.
Post pics and let us know what you do.
