Hi Andy,
I echo the previous comments.
The Flair Kite is a great plane, it's a nice kit to build, a nice plane to fly and as tough as old boots. You won't be dissapointed if you get one.
Mine is fitted with an Irvine 46 with 11" x 7.5"Graupner prop, which for me is a combination with plenty of power and a noise level well below 80dB.
