Had one of these as a present. Not bad for the money, but lousy instructions. The balance point is wrong and a number of other instructions and photographs are from the Tucano, in the same range. In my case I had to lengthen the cowl as the measurement given as 5, 1/2" from bulkhead to drive plate ended up with the cowl being 1" short. I had to add a strip of aluminium to the back. This entailed a re-spray of the cowl.

After getting the balance right by putting servo's in the tail, (I amusing a Laser 80) The thing is OK.
