RE: CMPro On The EDGE 540T
You could put an OS 160 in it and it still wouldn't 3D!
I had one last year and I wouldn't reccomend them to anyone! (sorry if you have already bought one..)
It was way to heavy for the size of it and the construction was poor (glue joints letting go in flight) I got a lot of flak about the airfoil... basically I think a 12yr old chineese child was asked to draw a picture of a wing and they went from there...
The control surfaces were way too small for 3D and because of the weight you would have to really overpower it to have any fun. I had an ASP 1.20 which I admit was a cheep engine, but I since sold it to another modeller and he put a similar size engine in it. I had a fly of it when it was set up and it was still a pig.
The colour scheme was terrible also - I got the american flag design but it had the same layout top and bottom so it was not good for aerobatics.
I hope I haven't put you off ARF's - I have since bought a couple of ZN Line models, much more expensive but they fly soo much better and the construction is way better that that of the Asian brands.
