Thanks, chaps. The other engine is now finished, although I've had to remove the exhaust on one side of the first engine as the inboard sides of the engines need to have struts on the inside of the exhausts, between the engine and exhaust.
Yesterday I spent a couple of hours cutting slivers of masking tape and sticking them to the wings. I sprayed them last thing yesterday and today I peeled off the masking tape.
This evening I fixed the 8 outer struts in place.
And then trial-fitted the upper wing. Also shown are both finished engines.
Next on the agenda is the manufacture of the engine nacelles and radiators.
