It's rock solid stable, I've reduced my over the fence speed from 100kts to 90ts and it still floats.

Denied LOBO (Lancair Owners Bulders Organization) instruction today due to self insuring. I'm totally convinced the Lancair instruction program is to protect the insured people. I am fortunate enough to be able to self insure but was denied "professional" instruction by a 40 hour time in type instructor (I have 30 hours so I question the quality of the instruction regardless). I wanted to reaffirm my confidence in the type but that is obviously not an option or a concern of the LOBO.
Regardless, this was an eye opener. I'm safe and confident flying the airplane but there is no instruction available unless you have insurance. I am also confident enough to say I am qualified and available in this type to provide instruction as needed.
I spend at least $30K a year in premiums insuring things; perhaps I should dump all insurance?
Bryan, any comments on this and your thoughts on "grounding myself"?

You deploy something that completely changes how the airplane flies while crossing the fence? Flying on speed stops the float, you'd be suprised how much runway a Falcon chews up flying 10kts fast on landing...

I get what you're saying, it makes sense. The plane feels really solid at 100kts and takes a lot of power at 90kts. I've never had speed brakes before but the technique seems to work. I have done something similar borrowing a friend's Mooney and it seems to stop the float. I guess I could come in slower and not use the boards till after touchdown?? Any thoughts?

Speed brakes work pretty well to take the edge off of a rough ride when descending but if I recall correctly use is restricted below 200' on those I've flown.

If you have a split deployment while crossing the fence it might not be pretty. Speed brakes on final are a limitation on many jets. Do you land the aircraft with full flaps? I've started landing with full flaps. I guess the split deployment of the brakes would be a similar risk to a flap split deployment. I tested what happens with the gear out, flaps out and brakes out and the plane still climbs at 1000 FPM; it's a beast. I will practice throwing the boards out only after landing; I appreciate the advice. I might need to slow the over the fence speed 5kts to do this.

Based on what I have read here, you are 10x the pilot I am, so read these comments knowing they are coming from someone with much less experience. That quote above makes me wonder what sort of approach angle is needed to NOT be dragging it in at 90 knots... What are power off approaches like in that bird? I wonder if an AOA indicator would help?

If i was going to use them i would put them out earlier, maybe turning base. I would never make that big a configuration change on short final, too risky.

What needs to be mastered is the bleed off of speed at the end. In the Falcon we fly VREF+10. It usually puts us in the 125kts range. If I hold 125 to the ground I'll float to the end. I must bleed that speed off at the end and touch down at REF+0/-5 or half a donut slow on the AOA. I'm on the AOA during the bleed off, airspeed is just at number at that point, I want to know what the wing is doing...

I've got an AOA. I think I need to practice flying the AOA up high. I've never used an AOA before but can really see the benefits of it flying a slippery bird like this. The Eclipse was much easier to slow down the Lancair.
