Thinn had a nice build thread on an Osmose 70 pattern plane from Kyosho using a YS-63 and a good flying report at the end. I bought the Osmose 70 and am impressed with the quality, but I am using a Saito 82 with a VP-20 Perry pump. I have to finish it yet so I have no personal opinion at this time but was impressed with Thinn's results.
