Completed the maiden flight of the 140 this week... it flew AMAZING. Seriously, one of the best airframes I've ever flown. This is significant as it proves that I'll be able to scale up a an airframe without having to do a large amount of testing or rebuilding due to a design issue. The Raptor 140 just flew... perfectly.
Next week I'll be completing flight testing to get to know its performance (maneuverability, stall speed, max speed, climb rate, etc).
See you next week!

hi trent, remarkable time achived on 4400 3S lipo. is this aircraft available as kit. what type of EPP foam has been used. are the drawings available?
Thank you John! I've since hand launched it by myself without issue, but in the long run, I'll need something more repeatable and "safe" as these are only going to get bigger and heavier. I've got some ideas I've been working on, and of course, will make a video of it. Thank you again for your support!
Crash: Ha ha! Sorry man... I just geek out on this stuff (hence the show's name). Thanks for watching!
Great work! I don't know what happy pills you are on, but they shouldn't been missing in the local drugstore.
Nice work Trent! You did a great job of capturing the nervous excitement of a maiden. We've been having great luck with bungee launches of aircraft like this. Small metal hook in the belly, forward of the CG, tent stake, ~20 feet of decent surgical tubing, 5 feet of thin braided nylon/kevlar tied to a keyring.
It makes the launches sooooo predictable.
Keep 'em coming!
JC
Thanks Mark and Gary! Exciting stuff...
Whoop whoop
Dudes! Congrats on a maiden!
I love your show and watching pretty much every episode. Trying to get into FPV and APM stuff myself.
Thanks for posting all the links for the equipment - it helps a lot.
Looking forward to see the future shows.
Cheers,
Mark
