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 battery capacity (2.2Ah to 8.8Ah)
Two times the motor power output (300W to 600W)
Better servos (9g cheap analog to 11g digital)
Better air flow (exposed to embedded electronics with canopy)
Better water proofing (plastic wrapped to embedded and sealed equipment)
Folding prop (8x4 fixed plastic to 10x6 folding carbon fiber)
Add current sensor (provides live, in flight Volts and Amp draw)
Seperate GPS & Compass (instead of mounted to APM, improves sensor clarity)
Improved Crash Damage Reduction (Batteries secured safely)
Larger and additional Carbon Fiber spars
And more...
Estimated performance:
Weight: 16000 gm
Flight Time: 40min - 50min
Stall Speed: 25kph
Cruise Speed: 60kph
Max Speed: 120kph
Radio Range: 1.5km

I was wondering about that too :)
Weight: 16000g !!!

Doug - Glad you saw that too! I'll trimming/embedding more once I know the CG is right. I love that picture! Very good demonstration of the principle. The kits will be priced very competitively. One of the reasons I'm making them is that I couldn't find a good priced one out there.
Fracis- Ha! You are right! One too many zeros : ) That would be pretty heavy!
i think you have a zero too much at weight, or is it really 16 kg ?
A wiring 'hood' would not harm the performance of the R140 and clean up the center section nicely. Maybe a sectioned pool noodle? I understand that in development, access for changes and tweaking is desired. If the right size, it might support the FPV camera from the back side and make it less prone to wind flex.
That said, embedding the major components is a significant improvement in the 'slipperiness' of the aircraft and this will result in needing less power to stay aloft. 'Frontal Area' is very important in aircraft flight efficiency.
Which one of these riders takes more energy to move through the air?
If it doesn't break the bank, I will buy one of your kits!

Thank you Gary! It is so fun to make these. I seriously geek out (hence the name!)
Yes, a lamination video will come soon (planning on the week of10/26). In fact, I'm going to start selling Raptor 140 kits late October/early November, and they will have VERY detailed build videos, including lamination.
Brilliant brilliant brilliant. All so professional oh did I say brilliant.
Please could you make a wing lamination tutorial video I have been wanting to try that for a while and have a wing just waiting to be given the treatment.
Ha ha! You saw that? I think you are the first one to notice that little clip. Well done : )
It is great to be back.
BRAVO! Good to see you again Trent.
Love the teaser at the end!
