Messerschmitt Me 163 Komet -- Brian Taylor's Plan

Hi Guys,

After viewing some videos from the "good ol' days" during the holiday break, I

couldn't resist having another try with the Komet.

I built this plane over a dozen years ago, but sadly it was not to have a long

life. The take-off dolly jammed on take-off and for whatever reason, I was

unable to get the plane back on the ground in one piece. It seemed to fly

quite well, even with the dolly attached.

I'm enjoying the build thus far, Brian Taylor's plans are hard to beat.

Dave, presume this is electric? I built the Jim Kiehl (?), 84" version and flew it up at the Midwest club for many years, I even think Keith flew it once. It had a Moki in the front back then but on moving here I converted it to electric and added ability to light a reloadable rocket motor in back. Unfortunately it has yet to be flown mainly because the old Airtronics sevos/extension leads have to be changed for Spectrum guidance. Anyway mine also used to take the dolly with it on occasion but I always managed to fly around and land ok. My biggest problem was that on grass, a bump would make it prematurely airborne, dolly would drop followed by an immediate prop strike !! Once in the air though I likened it to a big glider, very stable and very docile. Straight spin was neat, inverted spin was scary. Keep us all in the loop as this progresses.

Hi Killickb,

Thanks for your input, My original build utilized the elevator trim control surface as elevators and the outboard control as pure aileron.

This time around, I'm using elevons, rudder and landing flaps.

Did you find the landing flaps helpful on your considerably larger komet?

This Komet will only be 50 inch wingspan.

I'm hopeful to set mine up for Rocket Assisted Take-off as well.

I think the AMA is cool with R/C planes powered with up to G-sized Rocket engines.

P.S. Hi Mark,

Happy New Year, I've been Following some of your recent Posts, Cool Stuff as usual.

Hi Turbonut,

I'm looking forward to how your 40" Komet Flies.

What motor, battery and esc are you powering yours with ?

I'm finishing the upper turtle deck sheeting today and I hope to flip it

tommorrow and place lower bulkheads and begin sheeting.

Dave, my control was as your first one --- elevators on the inboard flap position and ailerons outboard. I did program in a crow position (don't ask me why?!) you know, up aileron / down elevator but it created some strange pitch movements, sure didn't give me a steep glide path! Never did program flaps, they would have had to have been on the ailerons (flaperons) anyway. Did have rudder which was very useful while on the dolly. This thread might just motivate me to get on mine but I am in the middle of a big electric Super Connie and we don't have a build season down here so -----. Isn't that giant wing fairing fun to do, sorts out those that can plank and those that can't !!

Hey Scott,

That sounds like a pretty potent power system, I was considering a 4 cell

pack also @ 70 amps.

But I may re-think and go to 5 cells at lower Amps. I'm planning on a folding prop (aero-naut)

How much current are you running with your 9-6 ? And the weight ?

Hey Killickb,

That super Connie sounds sweet ! Just How big is it ?

Yeah, the planking takes some patience, I'm not thrilled with my quality of

balsa.... hard as a rock or punk.

Hey Scott,

no need to respond to my questions, I remember reading the --

"Missing Me 163 recovered" thread and that was YOU.

That thread was part motivation for my build.

I just couldn't wait for you to start shipping

Awesome Molds by the way !!

cheers

Yep, G motors are fine with the AMA. At that size, you might be able to use the low thrust but long duration 32mm reloadables from Aerotech that were for the Bob Parks Phoenix r/c rocket glider.

you might need a little more thrust than it offers for a ROG takeoff, though. Perhaps have a 24mm higher thrust short burn stacked below the other motors and ignite both at takeoff....that would boost it off the ground, and let the long burn push you around nicely. Kind of like the two nozzle motor they were working on back at the end of WWII, on the real thing.

Hey Mark,

I'm planning on finishing with clear Monokote and Floquil lacquer paint.

It's basically how I finished my Mossie and Hurricane.

Those two are older than dirt and still look pretty good. (1993 & 1992)

I'm pretty sure that I've enough of both materials to finish this plane.

I'm going to try to "gloss" this one a bit more though.

-DG

Thomas B --- thanks for the rocket motor info. I'm probably going to set up the electric system first and later adapt rocket power after I'm comfortable with everything. But I will try to size the exhaust area to place the rocket engine.

Scott, looking forward to flight reports


... more pics tommorrow

Here's a few more pics....

I cleaned up some of the top surface planking.

I also mounted the firewall and started to block up the nose...

My month of February is pretty much lost for building, so I hoping to get this framed up this month.
