Always wanted to do a build just like this. Very nice. You're not serious about the pilot though are you?

1/6 Vk Dr1
here are a few more pics of the build so far. i wanted to post some pics of the etching i did this weekend, i'm still trying to master it but its seems to be going well.i etched all the belt hardware, the control quadrant. i stiil have to make a lot of parts by hand, things you can't etch and vice versa. the detail you can get is incredible. i also finished my WB guns and found that no matter how much you clean the WB gun sights up they never look qrisp so i made my own buy useing very fine music wire and sanding down some plastic tube to 1/32". i fabricated the control stick and rigged the rest of the fuse minus the turnbuckles as its going to to be covered anyway, as it is i'm going to need eight turnbuckles for the control cables. i have to get far more tension than you could put on a servo if i'm going to have a piloted aircraft.

spikkkkkkkk-- This is one of the most spectacular models ever seen on these pages.
I wonder if you can share how you propose to make the pilot? It's quite amazing to think that you'll have a robot really flying the plane. Mike |

Spikkkkkk:
Hats off once again! You work is simply amazing. I can't believe your level of detail and skill. Can you please tell us how you made the fuse... is it mostly with dowels and aluminium tubing? I gather this was not part of the original kit? Keep posting those beautiful pics. Alex |

SPIKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKKK,
Nice Job on the DRI! I have a 40" version, but keep thinking about the VK models 1/6 DRI. I am amazed at detailed parts you have made. Did you buy the kit from Proctor? It may be my winter project next year, I am currently finishing a 1/6 Pilot Tiger Moth I purchased on E-Bay, needs alot of work. can't wait to see the finished product! hope you have flown a DRI model before, they can be tough to handle AD |

Good stuff there. Haven't seen one from this kit since not long after I first learned to fly RC, back around 1982-ish. How a VK kit got to the north of Scotland was never explained - at the exchange rate back then, around $3 to the UK pound, the cost of getting one in the UK was staggering.
Best I recall, it wasn't this fancy either! You've put some serious effort into adding scale detailing. That thing on ground looping - I've seen several scale models of various sizes of the DR1 fly and the constant is, the nearer to scale the rudder is, the worse they get around take off and landing. Nearest I got was a slightly under 1/6th Focker EV/DVIII parasol, which I designed and built with a scale rudder. With that steep ground angle with the tailwheel on the deck, that huge tailplane and elevator blanks out the rudder - which means as you crank on the power to take off, there's no rudder to help out against the torque swing. On landing, it was okay as she came down the slope. Snag was, try a three pointer and I had no rudder. Some better if I wheeled her on, but as the tail dropped, the rudder went to being an ornament again. She lasted thirteen flights - the only one in any decent wind was around her eighth, the wind held her straight on her take off and landing maneuvres and I won the scale comp she was entered in that day! If you want some modern day proof, look at that itty-bitty BARF Dr1 tripe Tower Hobbies sell. Compare its rudder to 'scale' ![]() Your pilot is eagerly awaited - is 'he' going to actually move the controls, or just respond to them? I have vague memories of an article concerning a 'working' pilot that housed RC gear in a UK mag years ago, but they are vague and the success or otherwise fails to come to mind. Regards Dereck |

![]() Dereck is right re the rudder size, mine was a little insensitive on control too. I recall Gordon Whitehead greatly increased the size of his 48" Avro 504 'comma' rudder in order to make it effective. Steve |

i just finished the wheels. i was going to make my own spoked wheels but was going to cover them anyway so this is what i did. i purchashed a spoked wheel kit from manzano lazer for 15.00. there only good for up to for pounds so i laminated 4 pieces of 1/32 plywood ( very strong this way and light) and used a a center piece to expand and strengthen the wheel then i laced them up with the fishing line each side separately and then covered them with nelsons litefab. they came out very tight no wrinkles and give the illusion of spokes underneath. there about 75% lighter than the williams bros. wheels. here are some pics of the wheels and a few of the plane and where i'm at.

i wasn't really happy with the tires they just wern't quite there so i went out and found some 5 in rubber o rings and they were about an 1/8" bigger and heavier material so i cut them to size and sort of revulcanized together with some liquid rubber compound i made from the scrape and baked them for 15 minutes at 450 degrees. i tried like hell to pull them apart at the seam but couldn't do it so now i'm happy with the look and there exactly 4 and 3/8 ". heres a pic of the new tires you can see the difference right away.

here are a couple of pics of the lerhone. nothing fancy just a WB kit with some airbrushing and metal buff paint. i picked up a bayonets and barbed wire red baron to make robotic. it really is a nice 1/6 figure and great clothing. i'll post some pics when i recieve it.

I can just imagine the PMs flowing into his inbox right now: Mr. Spikkkkkkk, My name is XXXXX, curator of the (Choose one: National Air and Space Museum, Imperial War Museum, etc).. and We would love to be the future home of any aircraft you feel like constructing. Don't bother even asking what we'd like you to build - if you build it, we'll exhibit it!
Man, I'm in awe. Absolutely amazing, again. |

Only problem is it kinda makes a mere "flying model builder" such as myself to simply toss in the towel. It's rare to see such detail in a static model never mind something intended to be flown!
btw - whilst oggling the fine scale detail I didn't notice before that the actuall power system seems to be missing? I suppose the ESC and Rx will be installed in the pilot figure (antenna built into the scarf?) but the motor and battery and wiring are very well hidden. That LeRohn doesn't actually work does it? |

Absolutely amazing, and I always thought an RC pilot like you are building was a good idea. It (he) can be moved from plane to plane, if all are at the same scale, even at the field. Of course the control setup necessary to be able to use the RC pilot is more difficult than installing the servos directly, but all models built for the pilot would be completely scale, both in looks and function.

Master modelers like this are inspiration and teachers to all who aspire to some level of perfectionism. It's a shame that the many master modelers and others are not given mass media coverage and public acclaim that rock stars and sports heroes receive. Master modelers get most of their appreciation and encouragement from fellow modelers like us.

all i can say is i'm grateful lothar was a little runt. i would have to pic a plane with one of the tightest cockpits going to make a robotic pilot for and not mention my cockpit is modified from a kit which even makes it little smaller, thanks lothar for not eating your wheaties and smoking 3 packs a day at age 12. he looks like a little boy next to the baron. no way could i fit a 12" figure in that cockpit but lothar saved the day at 9.8".

Lothar was the taller of the two brothers - I noticed your Richthofen pic in Post #48 is labeled 'Lothar and Manfred', but it should read 'Manfred and Lothar' if you're going from left to right. You'll have to stretch that 'runt' pilot figure a bit

your right, oh well i'll have to scale him down a little bit , between 6.5 and 1/7 scale. i didn't know where to start on this pilot seeing as how it's going to be a pain in the ass that's where i started. i mounted 2 servos in the lower abdomen for hip movment. i have about a hundred servo's kicking around so i had to find the smallest and strongest, they have to be able to hold the stick and rudder in place just like a conventional set-up. i also etched some 20mm stainless steel joints. they will connect either to 3/16" hardwood dowel or alum. tube, maybe both. those will become his appendeges with hands and feet attached. this 12' action figure i hacked apart is the cheaper blitzkreg model and i'll be using the head, hands and clothes from the more expensive and better bayonetts and barbed wire version. i'm going to try and make it as light as possible. here are a few pics.

Hi all
I have only read the last two pages of this thread, I don't normally but in on other peoples conversations but in this instant I cant help my self in adding my congratulations to a wonderful build and a builder that deserves all the credits that bestowed upon him if he was inclined to enter the Top gun competition I'm sure some of the regular competitors would have to move aside to make room for him. Once again congratulations on a beautiful model. Regards Dave |

here are a few more pics of the pilots progress. every thing seems to work well at this point just understand it's basic robotics he will fly the plane he wont get out and shake hands with everyone. the bottom half walks very well and even has a certain stride about it. as i said before i'm building this pilot from stuff i have laying around so its more difficult than if i was a systems manager and had the finances to order muscle wire, actuators,framework and put them all together. they have kits out there for twelve year olds with all the hi-tech parts to build there own robots. so it's a lot of trial and error for me, try this try that. i built a quicki mock up of the seat and rudder bar and every thing fits well and works well so far all i have to do is connect the top half with the bottom half and build the arms. there is a total of 6 micro servos installed in the lower torso and upper chest. i modified this to sections from the action figure and will be the only parts i'll be using besides the head,hands and feet. i cut out most of the plastic on the inside to reduce weight and used balsa to mount the servos in the upper portion. these action figures are heavy they weigh almost 2 lbs so you could never use one stand alone for a dummy pilot even, not on this plane anyway. i'm going to cover the limbs with 3/4" super lite foam tubes so he will look muscular not like a bag of bones under those clothes. i'll keep you all updated on the progress. i just wanted to mention that round thing on his butt is a lite foam tire. he has no thighs so there wasn't much meat down there and i had to form the rest of his behind and it also houses a rare earth magnet thers one in the seat of the plane also so once they line up and connect his butt wont move off that spot i didn't want to rely on the belts holding him in place. all the alum. welds are with zinc and a special flux that would eat the paint off a barn door and once you get used to using it, it works extremely well. i'm going to do a intire 1/6 alum. frame with it one day soon.

If I had a rare earth magnet in my butt I would need a soft tyre to sit on too...
I think this pilot is absolutely brilliant, I've never seen anything like this before, it's such a shame that most of it will be hidden in that tiny cockpit as you said. I hope we get some video of him 'in action' before you install him in the plane. Steve |

I do wish to see video too. I'm trying to figure out how a single servo using only one end of the servo arm can cause both extension and flexion of the limb. I'm guessing that one of those motions is passive and that the sliding captive wire at the back of the knee gives it spring. There's a lever at the hip attached to the servo arm?
I'm amazed by this build. Mike |

I don't want to keep you away from the workbench but can you take a few close ups of the hip joint and leg as they attach to the servo. I'm trying to understand the mechanism. I'm looking to copy it at all, I'm just curious of how it all works and you get the desired motion.
I'm really looking forward to seeing how you will make the arms work the stick. It seems a pretty complicated integrated series of motions to mix the movement of the stick for ailerons and elevator. Are you planning on rotating the entire torso to gain the side to side aileron stick movement? I have to say that this thread has me more interested than any other that I've followed in a very long time. Mike |

I knew there was something familliar about you. I've told your story to my children and rode your ride at DisneyLand and for those of you who don't know Spikkkkkk's real name it's Geppetto, Pinnochio's father. In all Honesty I can't decide if I think your really from the future and the inventor of Skynet or Geppetto either way you have to be FICTIONAL!! this is too far out there! ![]() So How much time will it take you to give ol' Pinnochio life ? seems to me at this pace you should be done very soon! As usual, mind boggling work! Brent |

I get it now. As for your mechanism, don't even discuss it until your buyer signs the check. We don't need to know. I used a simple lever device in a foamie Sopwith Camel a few years back to connect the surface control threads to the servo. I think that someone called it a "walking leg" or something like that. Wasn't my idea but it worked. I wasn't trying to increase or decrease the load on the servo but rather to have the threads controlling the elevator and rudder mounted to a lever with the right moments.
Your robot build reminds me of something I saw online a few years back when I was into RC tanks. I was playing with the $90 1/16th scale Heng Long tanks but was always interested in the 1/6th scale (old 12" tall GI Joe sized) models. Way to much $$ for poor old me. Anyway, there is a guy, his named is Vince Abbot I think, who was making robots to man his Tiger tanks. I guess that they should more correctly be called "animatronics" rather than "robots" since they were essentially moving models while yours actually performs a task or tasks. I'm on the old PC right now so I can't find the links to videos of his GI Joe's doing their thing. If you don't mind me posting links I will. I don't want to clutter up your amazing thread. Mike |

post away mike, my thread is your thread and thanks for understanding. i'm poor too, thats why i'm building this with stuff i have laying around i mean if i could buy the parts and mechanisms it would be easy this ways harder but tests your resourcefullness and enginuity and you get more from it in the end, it's like wow i built this and works and from that pile crap like the phoenix rising from the ashes. look at the movie flight of the phoenix not the remake the real one with jimmy stewart and harvey kruegar. when they found out he was a model designer they died, big plane little plane it's all the same basic stuff and worked. your not to far off the mark with your walking leg. rob

had to tear down and start over. there just isn't enough cockpit space and i also had to cut the weight in half to protect my CG. i stopped thinking complicated because the best engineered things are simple with less things to go wrong. i'll post a pick of the new chassie i built. i tested the legs on the new pull-pull lower portion of the robot and they work far better than what i had. i'll keep you updated on the progress. he's just relaxing now but you can ,see the direction i took. the frame will be completely alum. and have complete X/Y for the right shoulder. little by little i'll get there. i did have his pants on when testing the legs and the movements look very real. i know it doesn't look like much now but with the built up foam and his clothes on sitting in that cockpit actually operating the plane he will be a stunner.

I like how you've redond the hip rotational movement. Very simple. I'm really interested in seeing how you tackle the more complex mixed motions of the arms as they control the stick with strength to actuate the controls.
You do great work. Mike |

working pilot
i got some more done mike. the right arm which is the control arm will have three servos, 2 to operate the X,Y and one to push the elbow horz. with the shoulder movement. the tape and chord is holding apart in position until th JB weld sets. theres also a servo for the head to move with the rudder. ive got four servos installed and one to go. you can see how the shoulder works. there's a servo turning horz. with the vertical shoulder servo attached, so if i take the jotstick and rotate it in a circle thats exactly what his arm will be doing. left arm is for the throttle which will control the arm. i installed a ball joint so no matter what action the pilot is takeing this set-up should be able to compensate for all the twisting movement. i'm trying to keep it simple and strong. a professer in college many years ago told me simplicity is the key to good engineering and every problem contains it's own solution. i never forgot those words. right now it weighs about 5.25 oz. and i don't expect it to get over 7 oz.. here's a couple more pics and i'll keep everyone posted on the progress. i also reajusted my control stick to control surfaces. there's not alot of room in this modified cockpit for the stick to move enough to get the movement on the control surfaces so right now the differential is 1/2" on stick translates to 5/8" at the CS. the way i had it before would have led to overcontrolling and probably a crash. so hopefully these new ajustments will do it. BTW do't let the way he looks fool you, i don't look so hot with my clothes off either.

Saying every engineering problem contains its own solution is a nice positive spin, prior to that I had only been told that every engineered product carries within it the seeds of its own destruction. I like your version better

well i'm 90% done just have to install some shields over moving parts and sculpt some soft foam to fill in here and there and then get some clothes on this pervert, some light air brushing on the clothes and skin for more realism and then stick him in the fokker DR1 and will see what he can do. here's a few more pics.

Hi spikkkkkkkk'
My dad told me of this thread but failed to give me the link I've found it now and have become completely hooked on following your progress! I remember your thread on RCMF for your other model, great levels of detail in that one too! I didn't realise it had crashed on it's maiden, sorry to hear that, but hey It happens.......I've crashed my fair share the same as I've had my fair share of success. I've seen pilots 'stitched to false controls that are linked to a conventional set up, I've also seen pilots with servos in them moving false controls. But this is something else, a pilot that is actually going to fly the plane! OK, you've got me hooked,.........when's the next update Oh, just one more thought..........perhaps you need to fit a spring up his backside and give him a german WWI chute, so if you do get in to difficulty he can at least bail out and live to fly again Keep up the fantastic work! Cheers, Walts. |

dr1 working pilot
just finished getting the pilot installed and fine tuning every thing, like with all my models i add a lot of detail so no doubt when modifying a kit like this you are going to have extra weight so i needed to balance. i use the vanessa system to balance my planes. i love it because you can do everything your self and you don't ned 4 hands. ive been through these weight issues before so now when i know a plane is going to be overweight i build a 3/8" arch in the cowl especially if it abs or fiberglass to give it strentgth and to add weight. it's only balsa so there not much weight there but what i do is drill about 24 3/16x 2'' holes to accept lead rods so i don't have to fart around to find some place to put extra weight to balance. it's already built in and will take anywhere from 1/2 oz to 1 lb. in any case the pilot works great and actually works and looks better than i ever anticipated. the throws are where they should be, it's all balanced,BTW i had to add almost 15 oz. of weight.i'm posting a few pics of the pilot in the cockpit in his leathers and also a quicki diagram of what i do if theres going to be a weight issue. i will have have video in a couple of days i'm waiting for a mini camera to come in so i can put somewhat in the cockpit so you can see what's really going on with his movements it will definately blow you away. i know this because thats what it did to me and i'm my worst critic. 2 or 3 days at the most and i'll have the video and i also want to add a little realism to the pilots face but useing some oils subtle but distinct.

Even if the pilot was non-working, he still looks superb.
A lot of otherwise excellent models are spoiled by the pilot figure - either too small/large, poorly dressed and too 'toyish' or (worst of all)...missing! I'm guilty of the last one, having no pilot in my Eindekker yet. Looking forward to the video. Steve |
