with adobe acrobat 10 all you have to do is print the pdf at 148% and then when the paper prints out you need to cut like 1/4" border off. the blank part around the plans is what gets cut off.
i can tile a set at 30" when i get home tonight.

Thanks!
I was using Adobe Reader X and I had a similar problem when printing tiles. Nothing lined up and there were large gaps of missing info. I tried a lot of things but if I remember correctly, I fixed mine by changing the portrait/landscape setting.

30 inch tiled plans would be awesome. i'm playing around with putting it into landscape but it still is coming out funky. missing huge chunks. i'm also on a mac so it might not work the same way as acrobat.

and then maybe a 22" ws to see it it will be better as a micro at that size with a 10gram motor.

in the case of a 48" that is getting to big for simple stick model. you would need more internal stiffiners and probably cover most of it in foam or balsa. I am not the person to ask on a bigger plane like that. since I started micro and have been doing a lot of small guillows and other rubberband kits and my only 32"ws or above plane I have had dove nose first on maiden from about 100yrds up.(forgot the servo screw for the elevator control arm.)
Don't be upset man! I have been accused of having a screw or two loose in my time. Servo screws are kinda important though
I love the Guillows kits. I built a few as a kid! Never flew half of them. Just loved seeing the skeleton go together. Never was very good at covering though.

Almost finished your bird. I named her the SBach420!!!! Will post the pics when complete. Just got to mount the motor and figure out how to install the hatch to access the battery. Using a 2s 1300 lipo. Oh and find some time I was at this point in the build a week and a half ago. Life got busy.

I finally got some good calm weather for a yard flight this evening with the new motor and batteries. This setup is perfect for mine. Turnigy Park 300, GWS 8x4 prop, Mystery 12A ESC, Gens Ace 3S 450 mAh 25c packs. It hovers at just a touch over half throttle and has plenty of power for pullouts and fast vertical climbs. I flew for 5 minutes and the pack read 11.7 when I plugged it into the charger. The motor was slightly warm. Mine is now completed to my satisfaction. I will weigh it with the battery tomorrow.

Edit: Recharge was 255 mAh. I think I can add another minute to my timer.

For my battery hatch, I used Blenderm for the hinge and velcro to hold it down.

that is great the plane is working good I cant wait to get mine in the air.
Yours looks great too and very nice setup I think I will be ordering almost the same setup from value hobby. unless you know of some place cheaper. lol cheap is good.

I believe, if I were to build this again, I would extend the middle section of the main 6mm wing layer inside the fuse all the way to the front to butt up against the firewall and the fuse halves. Not only would it give a nice central plate for battery placement, it would pretty much eliminate any flex in the front of the fuse with only a minimum of extra weight. I could still glue a plate in there to do the same job, but it would be stronger and lighter if it was part of the wing.

yeah that is my idea with an extra plate to glue in (W/ GG)like the motor mount section but horizontal from the front to the wing. A lot like the lil ripper fuse is.

Thanks for the battery hatch pic! Is it ok to mount your battery(obviously it is) to the side if the fuselage like you have. Does it not affect the CG or have you counter balanced by have reciever/esc on opposite side. I want to put my battery between the servos in the middle of the wing but man she's tight. This will make it hard to insert the battery, so your setup makes more sense. I am just wondering how nose heavy she will become and how to correct that. Again lipo is a 2s 1300.

Regards,

E.

I'd rather have everything right down the middle if possible but yes, I do have the ESC on the opposite side to try to balance it.

As expected, mine is a little heavier with the larger battery and the Park 300. Fully loaded, it weighs 9.2 oz.

I guess it would have helped if I added my pics. I hope you don't mind TheOne420

I am hoping this thing will behave better than the last one(a full fuse version not this nice beasty)! Shes was a might twitchy. I have just enough room to fit the battery between the aileron servo and the elevator servo. I am only concerned about taking away some of the inside wing/fuselage structural integrity. I can either lay the battery flat(I would have to cut it in deeper a bit) or verticle lengthways with the fuselage.
I guess once you seal the canopy thats it eh! No more access to the servos and such...guess I should remember to put my servo screws in the arms before I close her up Weight so far is 10 oz on the money.

The time has come. I got the battery installed securely and added a guide post for the rear control rods(bbq squewers aren't the best to use). Motor is mounted and I hope its positioned correctly. Time to close her up and go for the maiden tonight! Can I use a Slow Fly prop? My motor has the shaft for the hex fitting of a SF prop. Its an EP 1047 the orange colour. The motor is a L2205 1350kv for 100 watts. Fits perfectly but will it be too much for the motor?

That may be too much prop for that motor. You might be ok on 2S if it will fly the plane but it will cook it on 3S. Most of my 2205 sized motors like an 8x4 or 8x6 prop depending on the number of cells. I just couldn't get enough thrust out of my 2205s for this plane on 2S, even with a 9x7 prop.

Would I be better of switching to my Park370 1370kv? Thats what I had on my now broken SBach.
