Re: SPAD Extra build

They are actually called "Multi walled Polycarbonate sheets". Size is 4.6 mm and 6 mm. Use the one that is 4.6 mm.

Re: SPAD Extra build

OK folks, The extra is ready for its 1st flight today (Maiden flight sometimes seems like the "Only" flight Grin

). Everything in place, and locked in. Ready to glow.
Hope she flies well.
Will try and post the video and pics after I get back from the field in the evening.
Hope everyone has a great flying day
Safe landings
Doc

Yep, some programmable mix seems to be enabled (regardless of whether it is a heli radio or airplane one).

Re: SPAD Extra build

Flight Report:
Something was not right. The plane kept banking, first on one side and then the other. No amount of trim kept it level. Maybe the airflow over the two wing surfaces not being equal is doing it. But the glide was superb. So back to the workshop tomorrow and 1 wing to be remade.
Will update you soon.

Re: SPAD Extra build

Wing rock is a factor of forward speed, did this happen even at high speeds ?

Having wing rocking problem @ both hi & low speed may b bcoz of different aerofoil (shape of both wings). Can c in the pix clearly.

Re: SPAD Extra build

The difference in airfoil may be the issue but then it could be fixed with proper trim settings. If the trim setting is intermittent then the cause could be something else. Check if there is a wobble in wing. I suspect that the wing incidence is changing due to wing wobble.

I had similar issues with my red-spitfire on the elevator axis. It turned out to be wrong wing incidence.

My poor Extra took a back seat preparing for Amby and then the aftermath of Amby. But Now finally here is the flight video of the first flight of the SPAD Extra.
Waiting for comments and suggestions.
