Aerochia LT-1 First Flight Video

Tue May 18, 2010 9:04 pm

figured this group would get a kick out of something like this... my buddy Andy has been building lancair legacies for the races in reno. In his spare time he designed and built this plane from the ground up... 90% carbon fiber, weighs in just under 500 lbs empty with oil.

It went for it's first flight last weekend, and I made the trek out to the desert to document it for him...

Hmmm the area of the fin and rudder seems rather small in relation to the vertical cross section of the cockpit area. But what do I know ...

How does the nose undercarriage work? It seems counterintuitive having it pointing forwards. Does it rotate just at the wheel mounting point or does the undercarriage leg move so the wheel leans? I know the Predator has a similar sort of arrangement.

Was the nose inspired by the Sea Fury?

Nice looking plane though. It must be very satisfying to build your own plane like this and see it take to the sky, and return in one piece.

Well, there are no shock absorbers on the gear legs, so they need to be angled to provide some flex on landing.

it's a castoring nosewheel... it's spring loaded and pivots around like a shopping cart... controlled by use of rudder and differential breaking.

Thanks for that. Is a castoring wheel trickier to get the feel of than a directly controlled nose (or tail) wheel?

It depends I guess. Two of the planes I have flown have castoring nose wheels (up to a certain angle) and also nosewheel steering. While taxiing with differential braking isn't all that cosmic to get the hang of, I only use it if I need to make a very tight turn i.e. a 180 out of my parking spot. The rest of the time I use nosewheel steering, it's required by my operating manuals in order to limit the wear on the brakes (not to mention hot brakes after a heavy weight landing).

Hope that answers your question, if only from my small point of view.

Thanks for that. I was just wondering how the differential braking compared to using the nose steering, but I suppose, like most things, you can adjust, and as you indicate, it can give you a tighter turning circle when needed.

More specifically, if you are not actively on the pedals/brakes with castoring nose wheels, the plane has more of a tendency to wander. With nose wheel steering it's less likely to. Just my experience.
