New Product

Introducing the new 2m Kinetic DP !!

I figured it was time to formally introduce the all new 2m Kinetic DP! It has been designed specifically for high speed DS but with the unique set of airfoils from Dirk Pflug, it will excel in a wide range of conditions and flying styles. Its high aspect ratio wing (just over 17:1) and minimalist fuselage (by DS standards at least) is a very efficient airframe whether you are DSing at 450mph or simply cruising the frontside flying F3F style laps or pulling big halfpipe pumps. As usual, Steven Seim is credited with the CAD work and Thomas Pils with the machine work. Both have poured enormous amounts of time and energy into the effort to make sure that I was happy and that everything was made to exacting standards. Huge thanks guys!

I've been so impressed with the MKS DS6125 servos, I decided to include them as one of my design constraints. I am told that they will soon be offering a high voltage version as well as allowing for rotation greater than the 100deg now available. The current install was done with a DS6125 on every surface. All of the wing servos were installed with the aluminum frames with integral bearing kits, metal arms, and 4-40 clevises. The result is absolutely rock solid! The ailerons and flaps are both bottom hinge / top drive with tiny blisters on the lower skin. The current control surface horns are so small I don't think top fairings are necessary. I am considering the Rotmilan roll drive servo arms as well as a custom made servo arm and will see which works out best. The elevator linkage uses a 2mm ball link on the metal servo arm and drives the elevator with a carbon pushrod and 2-56 clevis.

I finally had the chance to maiden her yesterday at Weldon. Like Chris said, she was a total handful on the first flight thanks to an aft CG. Still not sure what happened there as I modeled it in XFLR5 and set CG and decalage for the same stability characteristics as the K100. After a couple more flights moving the CG from 65mm up to 58.5mm and cutting down both the elevator and aileron throws, it started to fly the way I was hoping for. With no ballast in the wing or belly, the weight was around 80oz and it was already settling into the groove and got a 323mph in 35mph winds. A couple flights later, we put 15oz of lead in the belly and flew some really tight laps (2-2.5sec) for a best speed of 372mph! I had a ton of fun watching Chris and Bruce wind her up tight and fast! I think they liked what they saw cause they both re-confirmed their orders after handing me the transmitter!

With its small overall size and sleek profile, I was a little concerned about visibility but after all three of us flew it without any visibility trouble, I am no longer concerned in the least. This one doesn't even have the flouro paint job I've become accustomed to!

When it came time to land, I only needed about half of the 90deg flap deployment to make it move backwards in the 30-40mph winds! After a nice easy landing, I couldn't wipe the huge grin off my face! Definitely one of the most fun DSing sessions I've ever had. I can't wait to see what it'll do in really big winds! From my calcs, the target weight is around 140-150oz. I think 15-20oz in each tip will get us close to the optimal weight and will make it even easier to stick the circuit in ratty grooves. I'm playing with the ballast option of adding dry lead shot to fill the D-box for strong conditions or flying it empty to make it more fun and easier to land in light winds. I hope to have that ready for next time and will report on how it works out.

Again, I couldn't be any happier with the way the K2m flies. I think with the new K2m, we have a sleek, fast, and strong DS ship that is an absolute blast to fly in a wide range of conditions...

That is excellent, Spencer! When I first saw the plane in person I was shocked at the quality of the build. I don't think I have ever seen any product of any type built as well as the K2M. That wing is s-l-e-n-d-e-r to say the least. I was curious how visibility would be but clearly you can see it just fine if she hit 372mph on her maiden day! Congratulations to you, Steven and Thomas for a successful project!

I was wondering the same thing but once I started flying it fast I was only thinking wow, I never thought of visibility, just speed, fun and don't crash So I guess it was pretty easy to see. Still looking forward to seeing a fluro/hunter orange, black and white striped combo...

Holy smokes that thing looks sexy!!!! I love the planform of the wing!

I talked with Chris Boz about the plane yesterday for a a little while and to say he was stoked on the plane would be a HUGE understatement...

I can't wait to see one in person, nice work Spencer looks like another winner!

Just in terms of the looks-good/flies-good department, I like the blending of the leading edge and fuselage (if that makes sense). Anyway, it looks great!

new Kinetic

Hi Spencer
The new Kinetic - fantastic - just wonderful this model!
If you plant on whether the ballast in the wing can also remove
(For us at home would be an advantage)

I love this model.
I have already purchased the servos in anticipation.
Now I just need to save the cash to purchase one.

Thank you for your hard work Spencer. We salute you!

I love the lines. Just dead sexy. Love the large fixed TE tips. Because it is a Kinetic I know the quality is A+++. Congrats again Spencer.
