Another set back

All was going so well...

I'd made the electrical changes that the LAA were asking for and then did some more ground running and high speed taxiing, up to 40 knots with the tail up. The Twister seems easy to manage on the ground and this was despite a significant crosswind.

All good. Until I went to clean the mud off afterwards and while cleaning noticed that the exhaust pipe seemed loose.

Sure enough it had cracked completely around the outside of the weld.

So it's cowlings off and all to bits again to get this fixed.

I am using a local guy who is guru. Does welding for Shuttleworth Collection aircraft and is CAA approved. He also repairs and rebuilds old Formula 1 cars.

I think he will be able to come up with a solution for a fix.

As always with these things I see a silver lining. At least it happened on the ground and not on the first flight which would have been bad. Also it gives me an opportunity to slightly change the angle of the pipe to clear it's fairing on the cowl as it was a bit close before (no heat damage to date but it's nice to know it will be 5mm further away in the future).
