Did you sell that to John "TEXX" Kolher? I think he had that pink and blue laser at NALL last year.?

I think that modified Lazer is called an Extra? Sorry dude, couldn't resist!!

Re: Why not a Laser.......

Why does it lack in knife edge? That side area looks enormous...

Re: Why not a Laser.......

Here is the start of mine. This one is 35% but will be scaled down for a 120 2 stroke for testing. I added about 3" to the fuse length, made it a little taller and enlarged the entire tail.

Re: Why not a Laser.......

I don't know why it was said to lack on knife edge.... I knew plently of people that had the Lainer's that would take off at a crawl and through it into a high alpha knife and climb out.

Hell a 260 and a lazer are really close.


Why airfoil the stabs?

I would airfoil the tail so I could put them on tubes. Just from an ease standpoint.

Re: Why not a Laser.......

I think a contributing factor to the lack of knife edge is a smallish side area ahead of the CG. From a side view, the cowl necks down to almost the size of the spinner. With a single jug engine, most of the jug is in the breeze. With a twin, the mufflers won't fit in the cowl. When I increased the fuselage length on my last one I increase both the nose & tail moments and increased the rudder chord. It definitely helped and with yaw authority.
When I built it in 1995, I didn't know what 3D flying was! I also didn't strive as hard for the power/weight like most 3Ders have today. Though it ran very well, my 3W-70 twin was a boat anchor by today's standards.
I wonder if my BME-105 would fit in a 33% laser cowling?!?

I agree, airfoil the tail and eliminate the pesky flying wires...

George Welcome Jr of Port ST. John Florida has a 40% Bud light Laser 200 with a ZDZ 160 in the nose. It has a airfoiled tail surface as one of the mods. It is bad ass And has been put through the 3D ringer. I will look for pics.

Re: Why not a Laser.......

Jeremy,

Jack Strickland I think sells some plans for a 40%er. Would love one with the long canopy like Leo's last iteration. The only thing I can think of why Lasers are not so popular is the cowling is not as clean looking as Extras and Edges.
