Description:

New hybrid drones are being designed here at the sandwichaero laboratories, smaller and cheaper than our actual 2000W hybrid drone.

next model is going to use 15" propellers and a 1000W generator, a configuration which will provide 5 hours of flight time with a light payload (up to 500g) and more than 2 hours with a medium payload (up to 2kg).

You can buy our 2000W hybrid drone from here: https://sandwichaero.com/products/hy1000-hybrid-uav

Here is a Focke Wulf I acquired in a trade. It was repainted, with Callie Graphics markings. The pilot is FMS, repainted to look more like a German fighter pilot. It also has Dave Brown wheels, aluminum cannons, and hand painted spinner. I also added padding around the instrument panel.

I live at the foot of the Smokies and would like to know if there are any locations close by (between Knoxville and Chattanooga) where folks are doing slope soaring. Have flown gliders with high-starts and winches but never slope soared. I will build a plane if there are suitable locations near by. If anyone knows of a location, please advise. Thanks, cph

Built this Star Wars K-2SO speeder bike some time ago, never flown due to not being the best pilot...yet / still learning. Hopefully later this year i have another 250 size quad for practising & fondling with iNav.

Props are for show. No idea how they will perform. I also have clear 5030 props. Might add LED's later. Top front panel is held with magnets for easy access to battery bay & receiver. I've used two top plates from zmr250's with 10mm standoffs in between as the midsection. The flightcontroller and esc are in between those two plates. Arms are standard zmr250.

K-2SO - Bandai
4X T-Motor F40 F40III 2306 2400KV
Betaflight - SPRacing F3
2x ZMR250 various parts + plasticard
Racestar 4x1 ESC - 20A I think
Balances perfectly with nanotech 3S1500mah.

Needful Things - Dry Lubricant - Great for Gears, Linkages, Wheels, etc.



Here is a link to the Video:
https://www.youtube.com/watch?v=-9yzjQH9MBc

I came across this item when I was looking for a way to extend the life of plastic & nylon gears on brushed motors and prop shafts.
The reason I like this stuff is that you can brush it onto the surface without wasting lubricant and it dries so it doesn't collect dust & dirt ;-)
It works very well and this is one of the items I always have on my RC Hobby Supplies shelf.
Since then I have found it work great on Control Linkages, Wheel Axles, Hinges, anywhere lubricant is needed and oil is not an option because of the mess and collection of dirt & grime.

Here is a link to this Item:

DuPont Non-Stick Dry-Film Lubricant with Teflon 4 fl. oz. Bottle


See you in the Air!

Oh dear !
I really was afraid of this ..
Can't do sweet SPUDS all with mixing ..
Probably because of the auto stability built into the board .
As soon as you mix , servos stop working properly ..

BUTT ....
WL Toys 949 control board to the rescue ..
The board cant handle the XK brushed motor , just way - way to big a motor .
And around 80% throttle , the board shuts the motor down .

Solutions -
1) Smaller prop
2) Limit the throttle to maybe 70% max

Anyhow , the plan was to do the second wing with a 949 board and a much smaller quad motor ..
I guess there is plenty of time to remove the XK motor , not like its locked in or anything ...
Such is life ..

working on custom pit mats , i should be able to do custom names and hobby shop logos , screen printed onto the material.

just unsure of what material i will be using . i have some yoga mat material now , trying to figure out how to get ink on to a textured surface properly right now.
i may go another route material wise ... still unsure.
