Flair Dara 20

My Uncle has kindly given me a flair dara 20 kit, rescued from his loft space in the hope that i may build and fly it. I am thinking of providing a brushless motor as i am in my comfort zone with electric rather than IC. I have searched the various forums and found a few links to videos and one build, but no clues what motors have been used.

I was thinking of a turnigy sk3 2836 as at this link

the nose has min dia 40 mm on outside. the E2k motors are too large...

I was trying to get an equivalent to a 0.2 ic but appreciate that there is no direct comparison. some have used the 1 hp = 760 Watts, so 0.2 comes out at around 300 W. some others suggest 50 to 250 times AUW in pounds (so this would be around 1.5 to 2 pounds so perhaps 400W.

The sk3 above has 400 W so looks a reasonable starting point. Has anyone got suggested approach? might need to post elsewhere but thought i would start here

I once tried converting one using 10 2/3 sub-C and a Astro Cobalt motor. It had about 350W (from memory) but was too heavy, and although it flew it needed a good chuck to get it airborne. With Lipo and Brushless I would expect 300W would be a good starting point. If possible get 350W+ and a lighter setup than I had and you should be OK.
