pic one is looking down the steering nozzle, I chose a 3 blade prop to do the work. Its set up with a traditional flex shaft and drive dog so other props can be experimented with. This one started out as a x437/3 that i turned down to fit.
Pic two shows the internal layout. I was given a roll of carbon fiber from a customer who does composite work for a living. Since the 3 printing came out a little on the thin side I decided to just do a layup over the whole thing to strengthen the drive and to seal it up. It worked out well, it runs dry and that is all i could ask for.
In case water does get inside the servo ( a Savox, will post model number later but it has 220 oz torque at .18 transit speed) will stay hi and dry, the mount was made using a piece of carbon plate i tried making my self and a couple trim tabs I had laying around to keep it from moving, a zip tie and velcro further aided securing it. Its seems a little janky but It's actually nice and solid and the velcro should absorb some vibrations.
pic three shows the linkage for the steering nozzle. I cut off the tip of a Gatorade bottle and left some excess plastic, I heated it up with a heat gun and did my best to shape it to keep it from binding on the stator nozzle. The steering arm is a servo horn I had in a parts bin, i simply CA glued the snot out of it, so far it's holding just fine.
pic 4 shows the intake, this is an area i feel can be improved on quite a bit. I didn't have any input on the design of it, this was just a test to see if it would even work, the design was borrowed from a 3d printing web site.
