Hi Wurger,
hope the pic shows what I use.
At this point I recognized a serious error in the planview of the engine. The engine tapered too much towards the cowlring. Bad news indeed.
Countermeasures:
I cut off the cowling after drinking two beers and than split the engine from the front and inserted a shim.
All the engravings, part of the oilcooler, all was gone. two more beers and walking the dog to prevent this kit learning to fly.
The pic shows the fuselage after repairs.
Once more 2K-Putty saved the day.
shaved and polished it startet to look again.
back on the road.
Ups, lost two exhaust-stacks! Never found them again. There is always a dropped parts eater around!
one whole week lost through careless measurements!
