Hi guys.

For a long time, I have thought of a way to build a simple system that "easily" can be mounted on a regular XC harness without too many modifications. When I read all the posts on this forum, it looks like I'm not the only one that would like such a system. So, why not make it a joint project.

I have devised a basic design that might be used as a starting point. The challenge is that you lean more backwards in an XC harness compared to a traditional PPG harness. So the system needs a way to adjust the tilt of the motorsystem when you stand up and when you're sitting in the harness.

In my preliminary design there is a system that can do this. It is activated through a wire (line) connected to the foot rest or the bottom of the cocoon. When you sit in the harness and stretch your legs, the tilt of the motor changes. Minimum and maximum tilt is determined by two pinlocks.

For me it is important with a KISS system (Keep It Stupid Simple). The more simple the system is, the fewer things can go wrong.

Mounting the system (preliminary design):
At the top, the system is mounted where the Emergency Parachute is mounted on to the harness (by the shoulder). At the bottom there are side supports to stabilize the system and counteract the tork from the motor/prop. There are also adjustable straps that extend from the end of the side supports up to the carabiners. This is to keep the system in place and push it in to the back so the side supports have effect. The straps will only have an effect when sitting in the harness. When standing on the ground the straps will automatically be loose. Here the pressure of the propeller automatically will hold the system in place and into the back.

Once the principles are in place and tested, we may consider making the most of it in carbon. This also gives a more ergonomic design and a better comfort for the back.

What do you all think. Could this be a joint project for those interested?

Regards Bo :-)

It looks really nice and sounds smart. But I don't quite understand how your spring system works. Do you have any close-ups pictures of it.

very nice work. One small thing, we have found that you do not need the rubber motor mounts.. not enough vibration to worry about.. but you may wnat them there as spacers... it looks as thought the flex in a non parallel way..

when you do your videos, can you include some info on motor/controller prop combo?

best, Peter (Ozeflightclub)

I agree. But in my preliminary design, the rubber suspension acts as a hinge so the unit can tilt ;-)
