Pizzaz with sliced ribs

<< < (3/5) > >>

Mike Quinn:
Bit more progress

Not sure if bellcrank mount is a bit over the too but should be strong enough hopefully.  I had to glue paper between the ribs to stop the leadout binding on the ribs.  Works a treat but not sure what other people do.

The 1/8” steel wire comes in handy to help sand in the TE shape before gluing on rear sheeting.

Cheers

Mike Quinn:
Hi

Wing just about done.  Tips/adjustable lead outs and last bit of CS sheeting to add.  Had to add a false TE as I dropped the ball on the TE thickness.

Weight at this point, 52”, without pushrod, tips, tip weight box, adj lead outs or flaps is 250g.  Heavier than I wanted but I did just use ‘odds and sods’ scrap balsa and 8Ib RC model wood.  The TE sheeting was closer to 10Ib.

I’ll save my 4-6Ib stash for when I can avoid flying into the ground so often.  LL~

Mike Quinn:
Hi

Nothing exciting but on with profile fuselage.

Was very flexible behind TE but stiffened it up for an extra 9g by cutting some 0.8mm carbon sheet, tapering from 18mm to 6mm.

Carbon cutting jig is a ChrisEdge BMFA (UK) design from the FreeFlight Forum reports.  Originally for making Carbon wings (cutting spars), for FF comp power models.

Works really well for all sort of cutting strip.  Can use a barrel micrometer for precision cutting.

Anyway, overkill for a Pizzaz  ;D





Mike Quinn:
Need to carve/sand a little channel on top and epoxy strip in then will cap with 1/4 soft.
