This was in response to vjindahl’s question about reinforcing the perpendicular fins, which are made of 1/16” lightweight sticks. 1k carbon tow would not be strong enough reinforcement for the fuselage. Dave supplies 3k tow in the kit for the fuselage reinforcement.

Ok, got It! Thanks! Also, I’m still having a little trouble with my motto stick design- I throes to design it using thin sheets of wood but I don’t know how I would hook the Rubber band on a thin sheet of wood, cause there’s nowhere to put the hooks. I thought about using the motor stick design that most axial helicopters use, but I think it would be too heavy.bjt4888 wrote:Ash,
The Freedom Flight kit uses thin sheet motor sticks with one strip of 3k carbon tow attached to each side. This is one possible fuselage method. You could try winding carbon around the motor sticks, but I would think that this method would add excessive weight if enough carbon and glue was used to provide adequate stiffness.

Do you recall the approximate time of the year that the post was?bjt4888 wrote:Ash,
I included a picture of a rubber motor rear hook in a previous Wright Stuff thread (maybe 2014 or 2015) that would work.
I would need help from someone with more expertise on this forum to find this picture.
