RE: wingspan b-17
I promise not to hijack your thread, just bring a little camaraderie and add a couple of shots of our progress on the Wingspan 1/9 scale. Frank's building, I'm paying. He is a Top Gun level builder with several B-17's in his resume already. I am always shocked by how much progress he's made every weekend when I come by with a camera. Still, anticipated maiden flight day is not till Spring '09. He enlarged the rudder a little to be what he considers scale and set back the firewalls some from plan specs to allow for good prop position on the Saito 125's we're installing.

lipos in the fuse. I really wonder if this would over power the bird as 4 4130 axi's would work maybe

RE: wingspan b-17
my van has fold down seats. i can fit a fully assembles gp tiger moth in her so I already measured. You ought to see the 1/6 scale makes mine look little but i dont have the money for that. The hardest part is you must be able to read plans as there are no instructions, what puzzles me is mike shows the servos in the stabs and fin but that would mean control horns(yuk) he also has a servo plate in the stab area inside the plane. I think he tried to satisfy both types of builders

RE: wingspan b-17
Sounds like you have a plan for transport. I saw the link on the 1/6 scale and checked it out. What a beauty. I saw a 17' wing span B-17 fly at the Byron show in the early 90s (their B-29 had crashed the year before). It had (4) 4.2 Sacks engines I think, and a pilot and co-pilot both with transmitters. It was awesome. Yours will be impressive in it's own right. I am going to send you a link to some internal actuators. Very cool and very scale like.

RE: wingspan b-17
thats what i was looking for the aileron thank you. ill use old fashioned torque rods on rudder and elev. each elev will have its own high torque servo . Reports are 90 oz will be enough but im going higher for saftey. Also ill run two jr 6v 3000mah packs parallel for power as this monster will take a lot of servosat least 15-20 servos

RE: wingspan b-17
heres the guns. OMG they are perfect resin replicas and the turret motors. motors will run on 2 aa batts and use a servo to reverse the polarity so the turrets rotate. im not elevating guns having the turrets rotate via radio is enough for me. again kudos to mike and his company he puts all others to shame

RE: wingspan b-17
mike designed this aircraft from boeing plans. Hes a cad operator full time so thats how he did it. Its a unique and perfect kit . Upper turret motor and mechanism working and in place. not as bad as i thought. it will work via a radio channel and a reversing circuit to go left and right. gun elevation controlled by the cam which was easy to make. third pic is the motor. it rated 5 v but ill run it off two AA batts. plent fast,

RE: wingspan b-17
I'm a member on many forums (not so active on this one looking at my post count) and I also have a couple build threads those other forums....and I get the same situation...with hits or replies. But the members that do reply, and thank me for the time, effort and skill put into not only the build...but also documenting for the thread makes it all worth while. Just know that for every reply there are dozens more just watching the thread with interest. There are so many good threads and builds that I read through front to back....and don't reply...even though it could be a great thread. (As I usually don't have much too contribute to that certain thread, that someone else hasn't already posted)
Take a look at the "hits" to your thread...it's a fairly new thread (early Feb you started it) with nearly 1700 hits. I think your thread is getting a lot of attention...as it should, you are moving right along on this project. Everything is looking really good....and I enjoy coming in to view your latest progress photos.

RE: wingspan b-17
thanks getting the top turret to fit the fibreglass and rotate took most of the day. Cutting out the windows will be a very impt step and need to get that right. I work 12 hours a day on this. when i teach i work 6 hours a day so thats why it seems to go fast its a work of art and im not gonna be afraid to fly it!
