I had to put my servo tray kind of far back to accommodate a Futaba RX,and I went with 19 strand pull wire so I took a small weight penalty,but my light is balanced at 65.5-66mm 221g with 11g of nose weight.
I swapped out the elevator screws for nylon and trimmed down the control horns to shave some tail weight.
Itís a nice weight now and does everything well! I was shocked at how it performed in massive lift with aggressive blowout! Rock solid at speed! And incredible launch.

Please remember every gram in the tail is several grams in the nose. 3g extra in fully painted tails plus a couple grams likely in the painted fuse = extra 20g nose weight…

I'd forgotten that was that supercool painted fuse and tails. That makes sense. I'm sure you'll still kick my butt with it this season David!

She be done and RTF. Can’t wait for a blustery day. I am also rebuilding my first BAMF. It was an extremely good flyer and I can only assume it came from the wing. Hey Thomas can I buy just a parts bag for the BAMF?

Sweet! These are the best deal in DLG! Got out with mine yesterday in Violent after storm lift. My light at 222g was able to break out in tough conditions and then handle ridiculous speeds in massive blowout while at the same CG! When the air went dead a hour before sunset I busted out the deviant and monopolized on the cool dead air. Perfect combo.

David,

You wonít win any dead air rounds but, I have a strong at the same weight and itís fun fast.

BAMF - ArmSoar Composite Gliders


Hi guys, I donít know if this has been addressed before or not, I donít have time to read 2500+ posts of what is sure to be an excellent glider.
Long story short, got my BAMF today, 56 days after ordering due to some inventory issue. The general manager hooked me up with a generous gift card for the shop though so itís all good.
The problem is this.. I ordered the RH launch bamf, and noticed some serious quality/design differences between my Bamf and a local pilotís.

My rudder doesnít fit square with the fuse ( a 5-7į bias to one side of the seam on the leading edge), the wing doesnít bolt down flat to the fuse because the rear hole wasnít drilled straight, causing a 2mm+ gap between the wing and fuse and when I *carefully* tightened down the crooked wing, the right wing has about a 5-10į steeper slant/ dihedral than the left wing. When looking straight down the fuse you can easily see the angular difference between the two wing tips using the elevator as a point of reference.

Analytically, I *could* see how a right hand launch model might possibly benefit on launch and left-hand thermaling with a high right wing and left biased rudder, assuming I mounted it that direction) however Iíve never seen a DLG that comes ďpre trimmedĒ or biased for left or right hand launch. I would assume the model would be perfectly symmetrical aside from which wing has the hard point in the wing tip for installing the peg.

Has anyone else encountered this? Am I right in thinking there is an issue with this kit? Also my friendís Armsoar DLG- which is a couple years old- has the larger checkered style weave on his heavy layup and mine is uni-directional on the wing and fuse. Has anything changed in their heavy layup weaves since the model came out? Iím a fairly strong guy with an athletic background and Iím worried Iíll break a light weave or standard weave on launch. This is my first BAMF and first new-to-me DLG, so Iím a little lost here. Any input would be appreciated. Thanks

Couple of things. You won't break the wing. Can almost guarantee it. I can launch my light layup with ballast to over 75m with no issue. My strong and standard layup can handle way more and take my launches. (I'm a power launcher) . There have been some issues with wing alignment out of one set of moulds. Talk to Thomas and he will help you out. The fin is not deigned to simply plug on and be square. It has wiggle room so you can adjust it to be square to the Main wing. The horizontal stab will be slightly off as well but that is typically on most dlgs. So when building fit main wing. Align stab with wing then set fin to be square with stab. Unsure about the difference in wings dihedral. What are you referencing it against?

Are you saying that the wing is warped? It should be perfectly straight when one wing is compared to the other with no twist in either wing.
