About this Plan
Pedro. Radio control sport model, for electric power. Wingspan 50 in, wing area 395 sq in.
Direct submission to Outerzone.
Quote: " Steve, I participated in the 'Build theme for first half of 2024' over on the RC Groups Vintage Forum....The vintage glider and or rubber powered free flight won the theme poll.....I found Pedro (oz8203), a slope soarer from 1974 that I've built as a powered glider with the thought that I can convert it to a hotliner in the future (we don't have many slopes here in West Tennessee and the Tennessee Highway Patrol frowns on us when we try to fly from the off ramps on I-40). It's also not practical to set up a high start on the runway because we have so many club members that would object.
Leopard 3536-5T 1520 kV motor
60A ESC w/ 5V-5A BEC
Freewing 17 gr metal gear digital servos
8x4.5 folding prop
Spektrum AR 6210 receiver with satellite
About the only thing I had to do was eliminate the taper of the forward section of the fuselage to accommodate the battery and ESC....a whopping 1/4". I also tried to lessen the overall weight of the airframe but not affect the structure. Had to scooch some formers around to accommodate the push rods, and strengthen the wing structure to tolerate the higher G forces of powered flight.
The original plans don't indicate the airfoil, so I used Airfoil Tools to determine what they used.....a standard 12% Joukowski.
So here's Pedro's speedy brother........ And here's a link to the build log: https://www.rcgroups.com/forums/showthread.php?4471067
However, she won't fly for a while......wind and rain for the next few days, and then temps in the single digits....I'll get a video as soon as feasible "
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

* 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.
