There's no massive turbulence caused by the canopy, unless the canopy is very poorly designed which is not the case for the Allure. I've seen jets designed to fly at Mach 2 with less streamlined...

Thanks Bill !
Unfortunately my friend who does the composite parts is swamped with work at the moment, so we can't offer kits for sale.

Thanks Ken !
This is only my second attempt at film covering; the previous model (Radiance) was fully covered in white film so it's a vast improvement. My prototype Radiance didn't look like much...

Setting the incidence angles with the TLL-90S angle meter.

I wish i could paint the fuselage but film covering doesn't look bad either. It's probably a lot less work too because film covering doesn't go inside the small scratches and you...

Sorry Bo, i think my message was confusing. I meant the TLL does the same thing as the Wixey (indicates a different value when turned 180 degrees). I think it's normal, the angle meter measures the...

Hi Bo,

I remember you added a little down elevator at low throttle mix to keep the downlines straight.
Could it be that this mix kicks in when you reduce the throttle for the stall turn?...

Hi Bryan,

Maybe you have a different Wixey, but mine is type 1 and it's certainly not under 60g as you suggested. The weight is 120g, as you can see in the image below....

Their website seems to be down at the moment....
