Well it flew - great! It looked a bit tail heavy though...

Yeah, it was hard to tell with all the wind blowing it around. The battery still has space to go farther forward, so whenever I get it back in (hopefully calm) air I can adjust that a little more. The tail-heaviness might be due to the receiver refusing to stay in place.

Great work brother ! truly appreciating your efforts . I wanted to understand that how did you build with measurements taken .
Can you guide me how to design a airplane , are there any standard measurements on setting the length and width . Also i had a confusion how to use 3mm vs 5mm board . Does 3mm for smaller planes and 5 mm for heavy size ? please guide .

I didn't have a choice between 3mm and 5mm foam board. I think the foam board I used is 5mm thick. If I'd had 3mm foam board, I might have used it for the tail and the formers to make it lighter. For setting the length and width, I built the Baby Hornet from a free-flight plan, which I converted into foam board and poster board. That, and my lack of skills with Inkscape meant I didn't change the size of anything.
I'm pretty new to designing R/C airplanes, so I guess the best advice I can give is that whatever you design, don't be afraid to just throw it up in the air and fly it. If it's a plane you built, you can repair it or build another much more easily than if it is a store-bought design.

Flew the Baby Hornet for the last time today. The tail broke off after a landing, and the power pod ripped out when I tried to remove the battery. I think it's time to retire this little guy, but I do want to make a larger one soon with flaps and ailerons to do some STOL stuff. It definitely needs to be way stronger for that to work. Back to the drawing board! (Or in this case, Inkscape.)
I'll post the video later today.

Oh man, looks like you figured out the cg! Excellent job. Lots of learning. The next one will be even better. Congrats.

Thanks! Yeah, even though the control surfaces are oversized and the thrust angle is all wrong after a bunch of crashes, it was pretty fun to fly! The bigger one will probably have lots of its own challenges. Hopefully I can start building it soon.

Isn't that awesome! I'm having a blast with it so far!@Hondo76251 your stol competition is taking over the forum
As a history and Aviation nerd one has to consider that a tremendous amount of airframes were designed with short, undeveloped runways in mind...
even a lot of war birds that one doesn't usually consider in the "STOL" category have a design element at their core that allows them to lift a tremendous amount of weight off of a very limited runway.
I was hoping that the parameters of this competition would actually allow for many different styles of aircraft to join in,

Progress! I changed the wingtips and h-stab, and figured out the rudder shape. Next up is the fuselage and deciding about the landing gear. I'm thinking about a fixed or free-castering tailwheel...

I've started planning out the fuselage, and come up with a new name ... the "Bush Hornet." (Get it? "Baby" --> "Bush"? Ok, I thought it was cute...)
Also, what do you guys think of this landing gear? It looks ok to me, but I'll still need some sort of tailwheel.

It wasn't really a joke, it was just a replacement of words.
That picture needs to be an emoji!

Ok, the plans are done! I have my doubts about how STOL-y it is, since the flaps aren't very large, but it's something. I'll start building in the next few days!
