Radical Edge 540 Motor ?

I about to get my Radical edge 540 and was wondering what motor and prop would be good with it. I am thinking about the EPS 350 but I am not sure what gearing either the A or the D anyone have any Ideas ?

Radical RC recommend the 370 with the A gearbox (3.75:1), so I would imagine that the 350 would do well with the A and perhaps an 8x6 prop. If you went to D gearing you'd need a larger prop and you'd get less speed than the Edge 540 requires.
Of course you could get a Graupner Speed 300 (which apparently is exactly the same as the GWS 350), or you could spring for the Black Diamond 301 or even a small brushless (Razor?).

Cheers, Phil

A Razor would be awsome on a radical edge. I have heard that the black diamond is just a retimed $10 eps300 replacement motor. If you retimed an eps350, you could probably outperform the Black diamond. A 2s etec 1200 would probably make any of the mentioned motors pull it vertically

I would love to get another razor (I have a 350 on a d gearbox on my miniflash and it is awesome) but I just cannot afford it now I can afford a $17 eps350A which is the direction I think I am going to head in. The edge just came this afternoon so hopefully I will have it built by the weekend . I do have an extra eps300c I might try on it Just have to figure out what prop to use

I'm flying almost a duplicate of the RRC Edge 540 with the C gearbox motor using a 10 x 8 GWS prop. It flies really nice, has plenty of enough speed for aerobatics, hovers to the extent that I can, but doesn't pull out of a hover.
