    I flew my 6" Black Fly today for a successful L3 certification with NCR in the Pawnee National Grasslands. The AeroTech RMS M1297W took it to 10,315' AGL at 600mph.

    I couldn't pick a favorite picture, so I didn't! ;p Video and altimeter data will be posted in the coming days.

    Congratulations George. Welcome to L3!
    You are officially the first one to fly a 6" fly and cert L3 with it at the same time. We're looking forward to one of your awesome videos.

    Wow, George, awesome pics and congrats on the L3. I am looking forward to the video as well. Of course, now that you're an L3 and have access to a plethora of motor choices I think it's only appropriate that you try to see what motors you can cram in that airframe. I vote for a Loki Blue M3664.

    I made sure there was enough room for a 6XL 75.... That leaves three more grains to go. :eek:

    Thanks, guys! Already eyeing the bigger hardware... Looks like ~3 miles and M1.4 might be possible.

    Here's the M1297W video:

    I am finding it is a bit more complicated build with the tailcone, getting it all to line up and connecting the retention plate with the long screws
    thank you George for sending me your build pics, they help a lot

    You could do the tailcone/thrust plate a number of ways, but here's what I did... Pictures and MixMaster parts list should be self explanatory.

    It's actually kind of fiddly to poke all five 4" long flat head screws down to the coupler nuts and get them started. I just live with the PITA because I don't expect to be taking the thrust plate on and off too often.

    It might be nicer to use 5 short threaded rods and put a second set of coupler nuts just below the thrust plate. Then you could use short flathead #10-24s. That would be slightly heavier...

    To make sure the 4" long flathead screws had plenty of thread engagement I stacked a washer, the serrated flange locknut, and long coupler nut on the bottom of the aft CR. I loc-tited the button heads to the flange and coupler nuts, if those get loose you're gonna have a rattle that's hard to fix.


    McMaster P/N and desc:
    92210A382 18-8 Stainless Steel Hex Drive Flat Head Screw, 10-24 Thread Size, 4" Long, Packs of 5 1
    90264A425 Zinc-Plated Steel Coupling Nut, Low-Strength, 10-24 Thread Size 10
    93776A391 18-8 Stainless Steel Serrated Flange Locknut, 10-24 Thread Size, Packs of 50 1
    92949A245 18-8 Stainless Steel Button Head Hex Drive Screw, 10-24 Thread Size, 3/4" Long, Packs of 50 1

    Here’s how I filled the extra volume in the cavernous nose cone and prevented the chute from packing down into the pointy part.

    Walmart pool noodles and shipping foam.

    I used a 42" heavy duty drogue and 144" main, both from Spherachutes, which seemed about right for our field at 5,500' MSL.

    An option, albeit at a premium, to look at is the Fruity Chute Iris Ultra Compact chute.

    Not only do they pack into small spaces but they perform as well as one or two sizes up, as compared to other manufacturers. For example, a 9' Fruity Iris may perform a well as a 10' chute from another manufacturer.

    Again, fantastic chute but at a premium.

    The 6" Fly flew again today. Perfect flight to 9,424' AGL on the AeroTech RMS 75/5120 L1420R. I installed the 808 onboard camera for this flight.


    Curious to hear other 6" Fly flight results as mine consistently out performs OpenRocket simulations. Be careful if flying near the limits of your waiver! Not a problem with my club's 20k' standing waiver.
