How Slow will it Go? Turbulator Tape Testing the E-flite DRACO
Ойын-сауық
Feeling the desire to tinker, I was curious if applying some aerodynamic treatments to the outboard, non-slatted wing sections on the DRACO wing might get it to fly a touch slower. While it flies plenty slow, my hypothesis was that there could be laminar separation out at the wing tips causing it to wallow at really slow speeds. So, I added some zig-zag turbulator tape to intentionally trip the flow to turbulent at the tips as that would keep the flow attached longer. I think it did help get it a touch slower and get the AoA a little higher as well, but ultimately you can only get so close to 0 airspeed. You can be the judge, it was a fun experiment to try. :) #slowflight #DRACO #TheRCGeek

That’s really interest. Something so simple making a huge impact. Nice one Chris👍🏻
Thanks Chris. Never heard of that.. pretty cool. Nice tip buddy, Skip
Good work Chris, I too looked at the slat fence line compared to the outboard washout and the standard boundary layer separation is definitely going to be aggressive at the tips. This addition would definitely help. I’m still trying to sort out the adverse yaw in the turns using better stick coordination rather than being lazy with additional mixing.
Great experiment 😉 Mick would be proud.
Turbulator Tape. Reminiscent of the Rockwell Turbo Encabulator, and I'm sure just as easily explained. Nice work and excellent flying!

good info. Always want to stall full ahead across the full span without a wing drop to either side....that is bad because that's how you enter spin territory. At least if you stall straight ahead you have some chance to power/fly out of it. Dropping a wing, not so much (as I think a lot of guys who have the Draco have found out)
Looks like it makes more than just a little difference!
Turbulant tape hummm nice work, nice promo Chris Hogan lol 😉👍🛩
Good one Chris. My KAVAN tires from SIG should be arriving any day (2 months back ordered from Germany). I’ll let you know how they perform when that time comes👍🏼

Yeah, no more ‘oops’ reminder. 🤣. I will say though, I did prefer the sound of the 2blade more actually. It has a deeper tone to it.
i found some vortex generators to the non-slatted sections , so far so good but I have not slowed it down that much
nice flying : )

I cover that in my full flight review (kzread.info/dash/bejne/dW2BqqSskqzNgco.html ) but the battery is the Spektrum smart 5000mah battery pushed all the way back. I don’t recall cg location specifically off hand but it’s in the review vid.
Don't forget tubulation on the horizontal stab. Do explore it. 🤘
Chris I had to get a new fueslage but forgot to remove the 4 wing locks that are screwed to the fuse. Can you 3D a set? Nobody sells these. Thanks
Nice test!! Maybe try leading edges like QQ uses??

Chris, interesting experiment. What would be the result if you change the front part of the whole wing with turbulator tape? Regards and excellent video.
@Thercgeek

Since the slat is there, that already turbulates the flow through the gap. So, adding the zig zag tape through that region won’t provide much benefit.

If you do a google search for “zig zag turbulator tape” you should find some sources. This is the 12mm 60deg type.
