Hello

Started building a Pizzaz to replace the ‘hand me down 3rd hand’ one I acquired.  The original plan has a foam wing and slightly more taper but I’m following the basic layout of the one I had.

Not built a full depth, sliced rib model before so feel free to comment.  OS 46LA powered. 

Cheers

Hi

Yeah, I robbed some of the parts from the original.  The pushrod is an arrow shaft.  Lighter than it looks 😀.  The travel is way more than it will need.  Probably 60 degrees or more.  Just looks tight in photo.

Lol, had more photos but lost the will to live trying to add them due to size restrictions,

Will have another look later.

I’ll put some weights as I go as not sure if I’m going too heavy here or there.  I’m making this one out of largely ‘odds and sods’ balsa … some of which came from the ‘waste’ off a 1/5 Slingsbury Petrel RC laser cut glider kit as you can see from the STB TE piece.  Balsa is too expensive to waste these days 😕

Cheers

PS this is what the finished model looks like before the ground got in the way.  Not pretty but good enough for learning on.  Had been messing with 2K base/clear finishing on Oracover film.

Hi Dave.

It seemed pretty strong, the wing was probably salvageable after the crash but I decided to cut it up into pieces to see how the guy had put it together.  It will be sheeted on the LE so kind of a D box of sorts, with cap strips and some TE sheeting.

I’ve built many RC and Freeflight models but not too many CL models and only one 46 sized model so some of this is slightly unfamiliar territory.  Lol, I used to be able to predict how much one of my FF comp models would come out to within 10 or 15g but this is virgin territory so to speak.

And I suck at flying CL too 😂

Looking good.   Nothing like good construction phoios.

From what I can see on those plans, the stab looks to be "flat" (no airfoil shape), with the leading edge simply rounded off.  I built planes with such stabs and they flew well enough.  But when I went to giving the stab some airfoil, tracking was much better.  The plane was more stable around neutral, and corners were more precise.  Less bounce (overshooting).  Anyone else with the same experience regarding airfoiled stabs?

None of that might matter to you but it is something to consider if you have not gone that far in construction yet.

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
