I'm already flying a fold-able tricopter with a diy tilt-mount to carry the LX3 camera but it's too heavy to fly as a regular AP machine.
While I could simply buy a turn-key large lifter, I enjoy the design and build process. I also like using techniques that don't require large $$$. Less carbon, more ali and wood.
The goal: A fold-able hex that can lift a diy pan and tilt mount with the LX3 camera with downlink
I already have a diy under-slung Trex600 mount that has done me well for 4 years. Pan 30 degrees each way, tilt to vertical. The engineering will be very similar here.
The Hex
Motors: rctimer BC2836-11 750KV, esc's rctimer 30A. Controller - test hop with a kk baord (already hex configured) but I'll be going the CC way
I like them large. I regularly get to 400' with the T600. I want the same from the hex.
Large carbon plate (top and bottom of frame/hub) is difficult to get (without selling the children) in New Zealand.
Options - laminate 2 layers of balsa and glass or carbon cloth each side as a sandwich. Possibly next frame.
Chosen route - 3mm pine plywood top and bottom. Easy and simple.
Arms. I tried 12mm pine in Mk1 but they flexed too much. 12x1mm aluminium is lighter than square tube. Harder to work with (getting things straight) but there is a way
The clamps / motor mounts are 12.5mm balsa laminated with 2mm ply top and bottom. Light and strong. I drilled through with a 12mm bit and pushed them on the tubes. Quite tight and oh so light Alignment will be done on the table before the clamps/mounts are either glued or screwed to the ali arms.
Here is the progress so far...
The 10x10x1mm ali channels underneath will give the hard-points for the mount while adding rigidity to the 3mm ply deck.
Time now to thread wire through the tubes. I have heard that it is good to have the esc's at least 75mm from the rx and controller. I'll probably put mine under the motor mounts. Can't go further than that!!!
