Rez's Jet Provost


Recommended Posts

It's confession time... I bolloxed it up! crying

The eagle eyed might spot that (to paraphrase Sesame Street) "one of these wings is not like the other..."

In my infinite wisdom, as I'm building this replacement wing I seem to have had a whole bunch of warning signs that someting wasn't quite right... and somehow I resolved in my mind to work around them and get on with the wing rather than stop, think and investigate WHY things weren't quite right. I won't go into the details but suffice it to say the wing trailing edge angle was all wrong resulting in a tip chord about 5mm too long.

Arse! angry

I therefore had a chat with Phil about this and ended up repairing the wing rather than start all over again. First off, trim back the wing to the correct profile and then de-skin the top surface to dig out the torque rod so it could be re-set into the correct position.

In the process of getting the epoxy off via Dremel, the sleeves of the torque rod got damaged. These were repaired with heatshrink tubing.

Where the aileron sits, since the hard balsa had been cut out I needed to replace it with a set of indivdual sections, carefully sanded to height to make a nice snug infill.

New rib TE were cut out of decently wide balsa, glued in and then the whole area was re-skinned and sanded flush.

And there we have it, port and starboard wings the same shape at last! Now to move back into the garage for the tissue and dope and spraying.... Eurgh! frown

Nice recovery Rez - great job! Repairing a model is often a good way to force learning and develop skills and methods beyond those of just building from the plan - so its great that you've had to scratch you head a bit and think this one through to a successful, completed repair thumbs up

Look forward to seeing the JP airborne again in April.
