I test flew the p-47 this morning and it flew good. It wanted to climb quit a bit but once I throttled back to half it smoothed out. After about 5 minutes I noticed a weird vibrating noise and landed immediately without any miss hap. The noise was the prop rubing a hole in the cowl because one of the cowl mounts busted lose. Taxing was a little difficult on the grass runway. It is a keeper!!!!!
