For those who have QB kits with 30 degrees up, are we able to modify the stops in the tail (non-strutural welded tube between the longerons) to allow... -
210 hp is enough in the 4-place to perform admirably. Planes like the Patrol would be overpowered above at 210 hp in my opinion, you are giving up landing...Leave a comment:

I used the left drain. It's not a big deal if you can't get every last drop of oil. The residual oil is next to nothing.
I do have a remote...Last edited by Battson; 01-12-2020, 03:07 PM.Leave a comment:

Some have been asking for an update.
The update is, heavy snow continues to prevent the aircraft from test flying. Expect more in spring...Leave a comment:

As I write this, I cannot recall taking water out of the gascolator (ever), it has always been intercepted by the wing tanks....Leave a comment:

Thanks for sharing.
You may find the gear oleo strut holes are a little tight. When the oleos extend during landing, they rotate upwards...Leave a comment:

My front seat arm is 690mm (27"), rear seat is 1450mm (57"). I probably measured that with the front seat fully aft, as the most conservative... -

One of the primary advantages of fowler or slotted flaps compared to other varieties of flap, they generate extra lift behind the CoP and lower the deck...Last edited by Battson; 12-19-2019, 02:36 PM. -
OK - let's back the truck up here.
A tight fit is a problem for later, you want some flex here.
Tight cowl overlaps are hard to get...Last edited by Battson; 12-18-2019, 11:05 PM.Leave a comment:

If we assume a metre of head generates +0.15psi in the fuel system, then one might assume -300mm of head in a low wing would relate to -0.05psi [suction]...Leave a comment:
