The undercarriage is done and mounted, two servos (noseleg & elevator) are in and we've strengthened up the elevator pushrod somewhat.
I also cut a honking great hole in the middle former to allow a large (20oz) tank to be installed.
The spinner bolts straight onto the cowling using a 6mm bolt and some washers (well I used an old pulsjet reed valve actually but washers would do just fine).
Great care should be taken to get the tank right -- pulsejets don't like bubbles in the fuel-supply and a leaking tank can ruin your day (and your ARF) so it's important to make sure there are no leaks and the clunk line works properly.
The next build video will be the last and then we go flying!
