check out my first scratch built...

i call it: HammerHead

it's got a 48" wing span and the AUW is just under 21 oz. i managed to fit all of the radio gear right at the cg, with the battery pack about .5" in front of it. i was also able to router out a channel along the leading edge of the wing and slipped tape weights in.

it balances exactly at 1-3/8" from the LE.

lets just hope it flies...

here's a better shot of the design...

this was taken before the radio install.

Hey Torc, that thing looks pretty cool! Did it take much weight to balance with that long tail boom and no nose?

This was my first SAL-flying wing ...

It needed appprox. 70g of lead in the nose, AUW 450g -> too heavy for competition, but a lot of fun

it took roughly 6oz to balance the thing...

i had to get a little creative to mount the radio equipment forward enough. bu it worked. i originally planned on this being an hlg but at 20.65oz, i dont think it'll qualitfy as one. im going to consider it a sloper instead...

correction!!! i meant 12 oz to balance

this thing. i thought it was using 1/4oz squares but they were 1/2oz ones instead...

How are the servo arms/control horns protected from the ground? I got tired of breaking them off on my M60, so got servo bay covers. You might consider getting some strong ones to use as landing skids.

When's the first flight?

im pretty busy with work so i dont know how soon i can get out for the maiden...

but... i will try and get out this weekend. i'll take pics and maybe even video. as for the servos arms, i think the tail being so high can give me some protection from the ground. but not much...
