    Just finished it. Now waiting on 1300mah batteries in the mail to fly. Definately can't balance with 1500. Can't wait! 20170220_162255.jpg

    I am considering this now since nothing is yet glued to the underside. I am thinking maybe 2 bamboo skewers? hmmm, maybe even 2 more carbon tubes since it seems the front needs a bit of weight anyway? What do you all think?

    Yes the front does need some weight and if you can add weight and strength in the right place what is wrong with that. Go for it:) Carbon tubes, I don't think bamboo would do much.

    I put a skewer in the Vert Stab, because I used Value XPS (MPF Grade B) for this build, and it felt a bit floppy, and I REALLY did not want to add more weight in the back. But yea, will go for the Carbon in the front.

    Yeah, even with shrunk tape on mine it is still floppy, I will probably put some 2mm carbon in the fin.
    As it is mostly windy in the UK when it`s not raining I feel that the weight penalty will outweigh the handling problems of having a floppy tail.

    So the A frame from the nose down to the 1st Carbon spar wont work, would have to cross the prop slot. Taking a wider angle not possible either. So I would have to add another carbon tube above the prop slot to complete the A frame. Will have to measure out, cut, and then weigh the carbon, make sure its not too much weight to add.

    Hmmm. My plans may have come out differently to yours as I could lay out the tubes but they wouldn`t reach the very front of the nose, just a bit shorter.

    lol, cmon now. If printed to scale, all of our plans come out the same. ;) Anyway, check out the very crude drawing I did. The red is what you suggest, but I think it falls too short of the nose. Where as I cover more of the nose, but will it be better? I dunno. :)

  11. I think if you shorten the existing cf rod, now take your red lines and it looks like they could almost run up the leading edge and intersect in the nose area, no blue required

    Yeaaah, that`s right you can get a bit further. There`s no need to go all the way, you want a bit of crumple zone.
    `You're just too finicky:D
    OK I will change the wording to cockpit area:)

    not true...baboo skewers are sometimes more effective than carbon..they will add strength and also bend a bit in an impact...i don't use carbon anymore unless i need a very long spar. With hot glue and some triangulation the bamboo will work very well.

    BadAxe...you have the right idea for sure..hope you don't mind i grabbed your pic....if you do bracing like i show below..with the black lines..and you make the points where the lower braces intersect the upper...that contact point reinforced with glue and maybe tape..you will have a very strong nose section...

    Not at all and thanks. But I am just wondering if adding 4 more tubes will put it overweight. I guess as I stated last night, I will measure cut and then weight the tubes, see what kind of weight I will be adding. I only say this because its mentioned you really dont want to hit 18 oz on this bird.
