Description

10 Feb 2013: BOM

1400mm 6mm sq CF tube (wing) 1400mm 3mm CF tube (wing) 1 length 5mm CF rod (tie down rods) 1 length 4mm CF tube (push rods) 1 length 1.5mm steel rod (pushrods) 1 roll - heat shrink adhesive film 1 roll 3M hinge tape 3 sheets of 1mm - 1.5mm balsa 2x 15mm 6 gauge screws 4x 30mm 8 gauge screws Wheels - 45mm dia x 2, 20mm dia x1 1300mAhr battery Motor and prop options as per instructions 1x 4 channel RF receiver 1 sheet, 3mm foam board (tail section) Supa glue and hot melt glue gun / sticks 2 or 4x 5g servos - tail plus alierons

24 Nov - New wing parts for a 6 / 13 degree poly wing option (200mm chord version only) plus updated instructions.

21 Nov - 200mm chord wing, left and right wing tips added, instructions updated.

20 Nov - lighter version of the 15 degree wing joiner uploaded, trainer width aileron updated also.

19 Nov - Major crash on SKU, lost a weeks solid work unfortunately, am also waiting on advice re replacement parts in AUS for my Bot.. so all in all, is progressing slower than desired.

I have uploaded what NEW files and parts I have tested and will look forward to completing this version as soon as possible, including a new set of instructions and parts list.

Two wing designs included in this version.. on with a 150mm chord, the second 200mm, (both in a Clark Y profile) for a lower landing speed, both are 1400 mm long, in a polyhedhral configuration.

Parts included for a dihedhral wing if desired for both variants.

Both wing sets have been loaded as zip files.

The current tie down brackets and wing mount will suit the 150mm version of the wing only.

09 Nov - After a series of flight trials it has not been possible to extend the hybrid version and maintain the same flight characteristics on a full ABS model. Is easy enough to fix. I have marked this version as a work in progress. Am presently redesigning an longer version, 1300mm wing span, with a 1300mAhr battery and larger motor to suit.

rudder and tail fin... nothing that could not be done during the fitting process, just a minor refinement.

05 Nov - Updated wing profile loaded with joiners and wing mounts, increased lift and slightly longer chord, but still within the requried ratios for the current stabiliser and tail fin.. not tested as yet.. but if anyone builds it inside the next week please let me know how it goes.. :). Recommended OAL wing length is 850 - 950mm. Adjusted rear wing mount bracket to follow, which will be at slightly closer centres than the current version. Zip file added for the new wing parts.

Also added the standard length tail section (as opposed to the short tail version in the zip file) as well.. fuselage length with this component is approx 68mm longer (is called tail section V3).

Modifications to the ABS / PS foam hybrid plane as published a few weeks back to restore the static balance and update the relevant build details.

Rather than having to download the files individually I have added a zip file of the .stl's.

Started makeing the plane right now. It looks great and I am already looking forward to fly it!
It was hard finding the right carbon tubes on the internet, but I found some.
I will print the plane in PLA, though. Hopefully that will work.
Great work, also the wonderful instruction!
the plane is split across multiple files.. if you can let me know what you were looking for I will happily upload the relevant SKU..
Hey could I get that sku file as well?

Could you supply a BOM. It would help in assembly.
I did read the instructions, but it was hard to asses what components are required.
hi Lobster.. have made a list for you.
About the "Balsa nose strip" where can i find it? or is it a part i can print? I am thinking of printing the panels aswell, as i can print fairly thin.
hi Lobster... that is a 3 - 5 mm square strip of balsa, sanded into shape.. hardware or hobby shops have plenty of this.
Hi,

I would like to know if you think this could be modified for FPV?
I mean putting a camera where the motor is and putting the motor on the back of the wing?

Thank you vry much,

Nick
hi Nick,

Is one of the options I am working on.. have just moved house, so busy with immediate repairs and getting organized... stay tuned.. :)
Just wondering what you use to slice the nose/engine mount, I am trying with slic3r and it slices the wrong shape and netfabb reports a lot of problem which the auto repair cant fix ?
Thanks
hi Maca,

It does come up with errors but prints ok for me.

I am in the process of revising the design for that part and cleaning it up, as per the post above, had had both hands fairly full the past 3 weeks... if you want to send me an email I can reply with the SKU file with the partially complete revisions as they exist at the moment..?

All the best.. Chris

hi Nat,

Sorry for the delay in replying... I've been traveling for a few days.

 Note the detail in the current version of the instructions re the 200mm chord wing.. I'm yet to get the chance to build it but based on the flying Ive done with this model to date I would probably build using that version with the 6 and 13 degree joiners for a proper poly wing. I'd retain the overall the wingspan (reduces wing loading to 10 oz / ft sq) but shorten the outer sections as it flies as if there is too much angle on the wing tips with the 150mm wing.

The only other thing I would do is make the fuselage 50 - 75mm longer.

Make sure you use the correct wing mount and position it as per the instructions to eliminate the need for all but a few grams of additional balancing weight.

Good luck.. will look forward to hearing how you went... :)
Is there any more updates with this? have you been able to make a video of this flying? im printing it atm and will pass to friend who flies.

Nat
hi Roboteernat... as per the posts above time has been very limited the last few weeks... stay tuned for a few updates and a video or three... :)
Have done a bit more testing with the wing at up to 950mm (in an attempt to manage the increase in weight from 520 g for the hybrid version to 740 g for the full ABS model) and it doesnt glide as it needs to for the kids to practice their landings. Am just knocking up a design for a longer wing chord with a flat bottom wing which I will print, test and publish inside a week... :)
 they are all options... pick one.. :) its full ABS if desired.. personally I am using foam board for the rear stabiliser and ABS elsewhere.. if you have an option re thin sheeting for the wings that would be great.. balsa in 1mm thickness is easy to sand and fit to any shape or size of wing.

Video coming... flew it last weekend.. want to get the designs revised to further improve the weight distribution as well as extend the wings as per the instructions to improve the glide ratio.
Congrats - I love it! I too would like to see her fly in a video.

One observation; since it uses carbon fiber tubes, balsa wood, etc., don't you thin calling it "Full ABS" might be a bit misleading?
Video's requested. Lets see it fly!
You beat me to it.  I wanted to do something like this....a lot of work....great job!!!
