I have the 1.20 TM 80" in the box waiting for assembly. Green models are sold in the UK by J Perkins & in the States by Pacific Aeromodels.
Anyway from what I have seen so far ; the quality of the wood and construction is excellent the covering seems fine, the harware is extra heavy duty and it is highly prefabricated, even the fuel tank is installed. All you need to do is screw in your servos, hook up your flying wires (no pushrods just like the real thing) intall your your engine & gears and the rest is field assembly which is quite a job with all biplanes. Looking at photos, the TM30 is similiar but smaller.
You can find a few reviews on both sizes in RCU product guide section and a full review in the Pacific Aeromodel website www. pacaeromodel.com.
Good luck
