I just bought the 30cc Aerobeez Sbach. It shipped today, I'm happy to report on anything once I get it. But there is plenty of good info out there about the company, and also a great build review by 'aesthetic dentist' on Youtube, who goes over the whole experience of buying and assembling the plane. The value is great, there web site is accurate with respect to stock and pricing (for example, I got the plane on sale, it was the last one and I was not able to add another to basket) and I got order/shipping/tracking information the next business day (which was this morning
I've been flying pattern for a few years (similar to IMAC but different kind of airplane). I flew in 1 IMAC contest last year, actually in a class above my skill level as no one else showed up to fly Basic (I will be OK in Sportsman, I just had never practiced snaps, spins, or point rolls before). Anyway, I think any decent scale plane is fine for starting out, and as said above the key thing is to set it up right and to practice.
Where do you live? You should try to find a club with other IMAC pilots to fly with, it helps a lot and is a ton of fun.
For this plane I am running electric. The receiver and servos share one regulated lithium battery. 6 channel radio can work, can also not work. I had the Airtronics 8 channel radio with which you can not set up individual aileron rates. It was a learning lesson. I had the Futaba 6EX radio before that, and found it lacked a feature I really wanted for precision flying. So, you can make it work, it might not be perfect and if you are looking to buy a radio, you're probably better off looking for 7-10 channels.
I still have to figure out servos. I have 4 Hitec 7975's which are marginal with respect to the karbonite servo gears (good up to 12lbs) and the 140oz-in of torque for most surfaces. I do want to keep it light, so I might use them and get a set of smaller/lighter elevator servos (Savox 0251 maybe).
