Re: Oil Cooler Locations

The first three Lasers built in Australia all had the oil cooler behind the seat for cg reasons from the first one. We had a ram air scoop on the LH side just under the wing near the trailing edge and the outlet under the fuselage with a dam ahead of the hole - worked well in fairly hot ambient temp...

Re: Laser Airfoils

If you overlay profiles of the 0012 and the 21012 you will not see much difference. We bought a wing kit with ribs already cut but modified them by shaving a couple of mm (from memory that's all it was) off to give us a symmetrical wing although not exactly a 0012 (also note that near the root the s...

Re: Laser 200 Build

I'm away from home so don't have access to my library.
I'd look here first for the minimum bend radius: ... B0007EL65M

Re: Laser "3 point" angle.

I've seen Lasers with different main landing gear lengths. Ours had tall gear, one I flew a little while back was much shallower deck angle. The longer gear for the S-2A was to provide ground clearance for the aileron spades under the lower wing. My S-2A was an earlier SN to which the previous owner...

Aerobatics Downunder

I'm sure that the regulars from Australia will join me here. I have seen a couple of new aerobatic forums fizzle out in recent years, hopefully this one is successful. I've operated Pitts for most of my flying career; a "Laser" for over 20 years (competed up to Unlimited); a Std Decathlon and now a ...
