Hi everyone, I'm new to the forums but am a long time builder and flyer so I figured its time to start sharing some of my design and maybe get some feedback. Bear with me as I get used to posting.
I've always wanted to build my own heli rocket but had no idea where to start with regards to blades and hubs. After looking at some off the shelf hardware I came up with this lego/rocket combo.
First flight was this weekend on a B4-2, went up around 200ft and the blades opened surprisingly cleanly.
Some quick build details
Those lego pulley wheels and the associated white rubber bands are the EXACT same diameter as a BT-50 and make for a near perfect friction fit.
The small plywood pieces on the blades make them completely field hot-swappable.
I know its kind of ugly but those yellow alignment sticks keep the rocket stable, if the fins don't hold down the blades at the right angle there isn't enough fin area to keep it flying safe.
The fins also originally weren't big enough hence the big 'fin/winglets'.
A longer shock cord would be nice as I think I made it way too short.
