About this Plan
Jacara. Radio control sport twin. This is a modern plan in PDFvector format.
Quote:- "Steve, I mashed together an Argentine Pucara, an OV-10 Bronco, and a foamie that I found on RCG called the Jackal ...took what I liked for each and came up with this, the Jacara, a high wing twin for 5 channel electric..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

Typical me....Well, DUH ! I went back and looked at all the calcs I did when I was putting this thing together.....I'd set her up with 7x5's (21 oz thrust each) originally...it's amazes me that she flew at all with the 6x4's (11.5 oz thrust each).... no wonder I had to coax her off the ground.. only had half the design thrust....What a Marroon ! I've changed the props and will re-maiden today

Hi There! Simon of New Zealand, here. I downloaded a Jacara plan. Enlarged some key bits by about 2.5 (the biggest my work photocopier can handle); measured the drawing and multiplied by 2.5 for simple dimensions and guessed the bits I couldn't be bothered to draw, measure or copy. Built out of balsa; used UHU glue, mostly. Covered with cheapo chinese shrink-wrap. Powered by two 2212 2200kva brushless; run in parallel thro two 30A esc; two 8 x 5 props. 2200mAh 3s. Rud, elev, ail and flaps. FLYSKY X6i tx, 6-chan rx. 4 x 9g servos to run ail and flaps - in-wing mounted. 2 x 3.9g mini servos to run the rud and eleve, both mounted towards the tail. Flaps about half-span, 15 and 45 degree selection. Tricycle uc. Main on bent ally sheet; nose articulate on bet wire! T/O at 30% thrott, 15 degr flaps. Cruise at 27% thrott. Full-flap landing........the thing almost floats backward in the right breeze! Excellent, stable flyer at moderate thrott; sort-of aerobatic at more ambitious thrott settings (as long as I have the height!) Pictures att [pics 006-008]. I love flying this beast. Thanks to the uploader of this (recommended!) fine plan and to the Site for hosting the service. Gold.

Nice work. What's the wingspan of your finished model Simon? Somewhere around 50 inch?
SteveWMD - 01/11/2021
Yip, as you say ......50in-ish. Truth to tell.......I haven't measured it and a variation is the addition of the solid sheet wingtips with top and botton tapered fairing pieces.

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
