Default CM Pro Extra 300 90... any good?

Hey guys,
Just wanting oppinions on the current CM Pro kits... are the quality alright? It seems their prices are fairly good for what you get...? I'm looking at a katana 50 and Extra 300s 90/120. Coming from a 40 size plane is it much harder to fly a 90 size aircraft?

Thanks james.

Good to hear!! I actually posted this quite some time ago.. but i bought one about 7 weeks ago now, and have built it almsot as you said! I used dual elevator servo's, and am running a O.S. 1.08 with Bisson Pitts and APC 15*6. It was due for maiden yesterday but wind then and today has been awful so i have been holding out, fingers crossed tomorrow will be better. I to had drama's with CG, and i ended up making a second hatch in the tail just forward of the rudder servo hatch, and strapped the RX batt to the former with supports. Even with this here and even using dual elev servo's and 4*40 pushrods with metal clevis' all round it was still a tad nose heavy. It needed about 80gm's to balance it. But i took a tad out so it was a fraction nose heavy for the first few flights. But i'll post up how it goes.
