Autotune D Values Outside of Range

I recently did a few rounds of Autotune on both my X-5 and X-8 flying wings. All worked well and both planes seem to be flying well, however, when I checked the derived values after the Autotune flights, I noticed that RLL2SRV_D and PTCH2SRV_D values were greater than 0.1 which is the supposed max value according to the parameter listing. The actual values for my X-8 are 0.172 and 0.139 respectively.Any thoughts on how this can be? Should I just leave them as is? Or should I reset back to the…See More

"Thanks for the reply.  I updated your post on the ArduPilot forum, let's see if it picks up some attention. I flew the QuadPlane today and faced some challenges with AUTO and QRTL modes, with the aircraft reacting in a super aggressive…"

"Iskess, without the Quadplane components it can loiter at around 9A (I'm using for 4S, so that's around 130W). Initial tests with the Quadplane setup show around 13A or so (190W). However I still need to do some more testing and dial down…"

"Jacques,what increase in amps or watts do you find it requires for cruise when flying with the quad booms on? My Skywalker seems to need about 160W rather than 120W, that's +25%. I haven't seem many people post their findings yet, so I…"

"Very nice build.  The Ranger seems like a great platform for VTOL conversion.  I really like the paint job you did too. I built something very similar for a new TV Show called DRONED.  We delivered it to Tyler Perry, who is a huge RC…"

"I am using Li-Ion 3200mAh cells in mine. 4P3S makes it 11.1V at 13200mAh. the pack is quite light. give me 70 mins with payload of 300 grams. max current at takeoo  is 22A. cruise is 11A."

"Yes, I think this is a really good airframe. If anyone is interested, I posted 2 build logs on RC Groups. Build log for fixed wing only Build log for Quadplane conversion"

"The ranger is indeed a good platform to convert to VTOL  If anyone wants to build one, I posted a build log a few months ago  http://px4.io/portfolio/quadranger-vtol/"

"I love long distance fixed wing planes. they are excellent for wild life conservation. the tigers can be tracked by picking data from their radio collars. so no need to risk humans for tracking."

Observer/Ranger Quadplane

Posted on June 16, 2016 at 3:30am 19 Comments



Here is a short build log showing the work required to convert my Quanum Observer to VTOL Quadplane. The mods are done in such a way that the Quadplane can be reverted to pure fixed wing in around 10mins for ultra long duration flight (+-80mins on 15AH packs) and when a landing…
