I actually forgot how I put the bump strip on. A picture helps jog ones memory. So I used plastic cut to fit at a right angle. The bump strip was heated in the Perth sun for a few hours. The strip had to be handled with gloves at this point. Starting from the front, the strip was stretched over the right angle plastic. The heat in the strip allows for a very snug fit to the hull when stretched and cooled. The strip was then cut and joined at the back with a custom carbon fibre cover over the join. When the temp drops the bump strip pulls tight to the hull. The strip was also glued to the hull with marine adhesive. It works very well and I did do this part right. I chose the PMX4 as my skirt. I did this because it was the newest design and noone else had a set on their craft. A very nice curved skirt with a replaceable wear panel. I went with a two tone effect using two different materials to make the skirt up. The skirts are fitted the traditional way with a batten up top to hold the skirt to the hull. Two screws that’s it. The the bottom is attached to the hull via Stainless steel rubber insulated p clips. The rear segments have the anti scooping flap fitted. Here you can also see the landing feet. They came off in the first 5 hours I suggest you really pay attention when putting the landing pads on they protect your hull from the car park!
These pictures are a mock up of the 1100mm duct to see how I might fit it. None of the duct in the pictures were used on the PMR1. The actual duct I used came from England. The Hull and all the work to this post was achieved in 4 weeks. I thought I had this build in the bag. I was very wrong it would be many more months before the PMR1 took its first flight. I decided I wanted a really good duct so I asked a business to do it for me. In hindsight I should have just built it myself. Time would have been saved. I would have the duct the way it is supposed to look. I suggest if you can build the PMR hull the duct shouldn’t be a problem just more time.
Now we are getting to the engine, drive line, belt and fan. Soon we will be flying in the PMR1 via my descriptive prose, scaring gremlins out, breaking down, trying plow ins on purpose, following dolphins, having fun!
