Oh good, I enjoy an occasional visit to the 'naughty step'...
In my opinion, the Portugese Chippes are little beauties in their own right - do you know if they aerobat them in Portugal as we can't aerobat the UK Lycoming Supermunks? The extra 35 horsepower gives the Lycoming Chippy some real extra oomph when it doesn't have a glider on the back. We operate them at ~£65/hr compared to the inverted oil set-up that is normally at least twice that. BBMF Chippies have been brought right up to date with electric starts, modern radios and a PowerFLARM. All good mods making these classic aircraft useable for the foreseeable future.
