Are you just starting with RC and UAVs? If so, something that's crash-resistant like the EasyStar is a lot more important than interior room. If you're an experience RC pilot and cost is no object, the the mini telemaster is fine. The EasyStar can carry everything we need, including HD cameras, autopilots, loads of wireless gear, etc, but the mini telemaster does have more room inside (although it's not as easy to keep the payload centered on the CG.)
Two other choices which are similar and in the price range are the Alpha 40 electric and the NexStar Mini EP.
Foam does have durability advantages, especially if you are a poor RC pilot, but traditional balsa planes do have a big advantage that Chris did not mention. They fly faster, which makes navigation, particularly in wind, much easier.
If you are interested in interior room and capacity, but like the durability of the Easystar, then check out the Skywalker (best current deal is at BEVRC.com, I think).
take a look at the new multiplex fun cub. I just got one and am building it up. It has lots of nice pockets for gear lots of room. It has ailerons,flaps, 55 inch wing, 40 oz stock weight should be real stable and its multiplex epp. It's goes for $120. I will know how it flies in a couple of days. hobby people has it on sale for $99. it evan has a tow release and realy big weels that will handel any surface and breaks down very nicely for transport
My first real plane was a mini-Telemaster. 47" and about 3.5 lbs full up weight. It flew beautifully.
Some observations on how it flies:
- It is too light to avoid nosing over, when taking off and landing on grass. You will have a lot of bent motor shafts.
- It is very light for flying in any wind. A 5lb plane will be a lot more stable.
- A bigger plane will also have more fuselage room, for putting in cameras.
- You'll need wheels about 3" big to roll on grass.
