"The other way you can slow down a flying wing is to increase the reflex in the wing and move the CG forward. This will create more drag and extra lift (to a point) 
For example when launching a flying wing it is normal to add 15% up elevon to give a…"

"No to all those choices, they will all cause overheating in use or charging and the last option is positively dangerous! Don’t do it
You can parallel batteries as long as they are the same AH, same volts, same C rating,"

"1)  Yes, I refer to the skywalker X8 but they are usually loaded with heavy batteries and you wont hand launch these beasts. do a search for the injuries caused to people trying to do that. they are also far from flimsy. 
2) yes and no, We do just…"

"Hi Grant
We aim at 18-20m/s launch speed, slightly higher than your 15m/s as the aircraft are different, The 3G is based on initial acceleration not constant acceleration as that is impossible with a bungee or spring system and difficult to measuere…"

"I see where you are going but even a 10 meter track would still need about a 3G acceleration, not exactly portable !
If you are going that way then I would seriously recommend using using a large stepper motor with a suitable gearbox and a…"

"It does not matter, Truthfully I never noticed if it did or not. the important function was that whatever the orientation of the drone that pulling the stick back brings it back to the point above the launch position, moving the stick left makes a…"

"Hi Grant
We have been building and providing medium sized catapults at www.Air-Vision-Air.com for members and others for several years. 
These are mainly for fixed wing and flying wing aircraft up to 6Kg ( Typical Skywalker X8) . our part number…"

"check the manual.. you can set simple or super simple for each of the existing modes. 
Super simple is exactly as you describe. it works great and has been implimented for a long time. "

"My guess is that when you changed the mode settings you did not write the changes to the flight controller. there are times when the write function does not operate correctly or automatically. 
It always a good idea to WRITE the changes you make and…"

"This is because you have the simple mode set on the mode switch and the super simple set to CH7 
This makes the system see both Simple and super simple at the same time when ch 7 is ON,  I had the same problem last week. fixed it as 
mode switch…"

"I cannot get at any logs until much later today.., 
The easy way to see this issue is in manual control, The X8 flys well under RC control and if Adverse yaw is the problem then when the aircraft is in level flight and you command a medium RIGHT…"

"This may be a mechanical issue? does the aircraft fly OK in stabilize?  or is it hesitant to turn ?
I have seen a similar example of this with a flying wing where the down going Elevon in a turn was causing the aircraft to Yaw in the wrong…"
