Thanks to Hooks for turning us on to the new Skywalker foam UAV platform. Mine just arrived and based on a quick inspection, I'm pretty sure this is the one for me! Everything about is totally optimized for a UAV, from the payload capacity to transportability. I'm blown away by how thoughtfully designed this one is.
It's got it all:
- The durability of foam with all the interior room of balsa
- Payload area right under the CG, so you don't have to worry about balance issues
- Hand launchable, but still can carry pounds of payload
- Breaks down easily for transport
- Ailerons and optional flaps
- Pusher, high-wing configuration, with servos outside to save room inside
- Super tough EPO material
- Easy to get to equipment with big bay doors on both sides
- External mounting spots on rear fuselage for wireless transmitters (keeps them away from other electronics)
Here's a shot of a prototype being flown by the creators:
Rather than give it a full review (I haven't flow it yet), I'll just give first impressions in pictures.
Comments
I'm on to something not digital, but with and without metalgear.
Don't fall for the notion that digital servos are "better". They're really only meant for aircraft that need very tight control, like 3D helis. They're actually worse for aircraft like our because of the constant current drain and buzzing on the ground when they're fighting gravity effects on control surfaces.
Henge MD933 digital servos have following technique characteristics:
1.Use metal gears, especially use steel material in output gear, which has better intensity , abrasion resistance and accuracy, makes sure servo’s output deviation very small after long time running.
2. Use high quality motors as FUTABA's, makes sure the servo's life longer, and tests prove it can continually run in high speed for 50 hours.
3.Use Japanese raw material to produce outer shell, which is more sturdy and durable and can bear 120℃ temperature.
4. Rapid response control, better acceleration.
5. Very nice consistency, center error less than ±0.5 degree, angle ±40 degree, biggest ±60 degree, error less than ±0.5 degree.
6. Have overload current protection function, even if the output gear is blocked, motor and electronics component will not be damaged.
7.Suitable to be used in 450 dynamoelectric helicopters to control the inclined dishes and in fixed wing airplanes

Something like this will fit, but I'm working on finding something more quality for use with Gyro.
drill hole in carbon horizontal tail boom & glue 3 mm rod in to hole with epoxy... make a small grove for rod and glue together fuse as normal. 2-cents or non-sense?

you can see it in other places too.
This UAV should bounce well !
Many thanks for that info, i will probably wait a week and then order it to my new address., please save me one. ;-)
