This week the Raptor 140 completed a 30km (18.6mi) fully autonomous flight! It only used 58% of it's 8.8Ah batteries, giving it a potential ability to cover 51.2km (31.8mi) on a single charge, the whole time flying at 75kph (47mph) for 40+ minutes! Impressive...
Some additional metrics to consider: is average amp draw was 12.8amps, or 21% of the 60amp esc, also it had a 5.8km/Ah (3.6mi/Ah)…
This week I conducted the Raptor 140's flight testing. I put it through the paces by testing it's general maneuverability (pitch and roll), high maneuverability (rolls, loops, climbs), its speed performance (cruise, max, stall) and it's technology performance (video, telemetry, GPS, compass, autonomous flight, etc).
It passed all its…Continue
After two months of research, testing, designing, building and just all out airplane slavery, I've finally completed the Raptor 140 - the next generation of the Raptor flying wing family, which is the next performance step in my USA trip next summer.
Check it out!
Improvements over original Raptor:
Four times the…
Here is my FPV Village Video with my FPV-Raptor
FPV Raptors shipment has come in & for a limited time, Cheap Drones is selling them for only $99 dollars! Sale ends quick, so hurry.Continue
While adding the AMP to the Shrike, we wanted to understand Flying Wings a little better and explore expos. We incrementally increased expose to 0%, 30%, and 60%, then flew the Raptor with the existing vertical stabilizer at 100%, 50%, and 0%. We were surprised to find that it flew just fine with 0% stabilizer! This test was in low wind, however, so it will…Continue
We did some testing of the Raptor in the wind - stronger than we've ever done before and had some very compelling results: flying wings (or at least the Raptor) do awesome in the wind, i.e. hold a fairly good heading and can withstand most jarring. The Nova in the same situation could have been disastrous.
We also continued our effort to finish the Shrike - a flying wing w/ a fuselage that will be powered by an APM2.
On this week's episode of MyGeekShow we repaired the Nova after it's horrific crash last week, tested our airspeed sensor to see how accurate it is, raced the Raptor around the field trying to measure it's speed, and finally installed a camera on both the Nova and the Raptor. And I may have crashed the Nova again. Yeah. Not good.
This is a new format, and obviously longer. Let us know what you think!
Welcome Nick to the show!
This week we tried to compare the Nova's max speed to the Raptor, however a radio Tx/Rx failure occurred during the Nova's takeoff, causing a massive crash that nearly destroyed the Nova. Never use a 5 year old cheap Tx/Rx on your handmade custom airplane.
We then tried to get a max airspeed for the Raptor, however our airspeed sensor continually gave suspect readings. We decided to go back to the…Continue
This week we adjusted the control surfaces on the Raptor to get it all balanced and flew it a few times to get more experience and test the airframe's performance. I've got to say, flying wings, and the Raptor specifically, have far exceeded my expectations... it flies great!
Its very, very stable, has an excellent power to weight ratio that allows it to climb indefinitely, enough control surface and authority to allow a perfect…
This week I overcame the challenge that is making foam wings out of sheets of foam... hard to describe, you'll just have to watch it : )
I finally got it down and cut out two wings for the Raptor, taped em' up and got the electronics ready...See you next…Continue
This week I got a great start on building the Raptor - a 48 inch wingspan flying wing. I learned an enormous amount of information:
1.) 3M 90 Spray foam Melts XPS Foam...
2.) Loctite Foam Board Adhesive Is a great foam, give it plenty of time (24 hours+) to dry/cure
3.) When cutting out flying wings with a hot wire cutter, both sides of the wing (if using a two template method) need to communicate very well
4.) A 12v car…Continue
The Nova is grounded while I figure out the APM troubles I'm having, see these posts for the details:Continue
