Hi everyone, This is my first Forum/ APM Experience... I am trying to have my X8 fly with the airspeed sensor but I am having a really strange behavior. I have the APM 2.5 directly from 3Drobotics,…Continue
"I'm in for a pair if this moves forward….. X8 carbon Kickstarter Campaign??
As opposed to "Just" an x8, it would be great to compile all the mods and custom revisions into an open source file; things like:
"I strongly disagree with the issues you guys are raising about weight. If you build it right it can be very strong and still quite light. I fly fully moulded gliders and they are bullet proof compared to what is required for a X8
I Like the…"
"although I have just put a 5mm carbon web along the length of each wing just in front of the elevons, 600mm length. Has enabled me to have another 10m/s before flutter happens.
Simple, easy & very light, but it is a bodge."
Both the FDM (Stratasys Fortus Ultem) and SLS (carbon filled polyamides from SolidConcepts) we have used for X8 sized blended wings yield no discernible surface roughness, although grooves could be added to minimize drag for low…"
It only takes a few hours to print an X-8 sized aircraft using SLS. (It takes about 36 hours with FDM.) The principal hurdle is cost. Glass filled or carbon filled nylon is expensive and only a few production facilities are…"
"There are several composite blended wings available including fiberglass and carbon fiber. One is now in service in Africa supporting counter poaching missions. Optimized composite blended wings have a somewhat different shape as…"
Hey guys! (and girls) I noticed a lot of people do love their X8 but they are pimping them quite a lot... Most of the time going above the max weight of the aircraft or going faster creating flutter. A composite airframe would help a lot in stiffening the desing and pushing the enveloppe. If I was to produce a composite airframe from an X8 completly in fiberglass, would there be interest from members in this forum? I do not know how much it would cost so far. Just a ''yeah I would like one""…See More
In the log file you sent me there are a lot of parameter changes during the flight, so it's a bit tricky to evaluate, but there are a few things I can help with.
First off, I suspect you may have loaded a config file from someone…"
"Awsome Thanks a lot for the help! Here is the Tlog file. I hope that I nailed the issue correctly and not mis-interpreted the data.
The Waypoints are really close to each others... my safety pilot was a little stressed. Next time I'll try to…"
The airspeed being erratic on the ground is normal, as the airspeed goes as square root of pressure difference. It will settle down once you above about 5m/s, and get more and more accurate as it gets faster. Do make sure you calibrate…"
Love flying wings, I think it is the perfect way to minimise the wet area not used for lift. Former merber of VAMUDES at University of Sherbrooke, I still love UAVs for their great potentials and accesibility
