Hey Guys 
New to FT Forum, came here from RC Groups, think it was Mr Man that pushed me to come here thanks to his great CAD tutorials.
Recently been crashing 3D printed planes which was getting to me a bit. So I decided, I like what Flite Test does, lemme give one of their planes a go. I had some correx on hand, some spare electronics so why not. To better my CAD skills, I tried to make it a hybrid so Correx + 3D ABS printed parts. More on that later.
Built from the original Baron plans, just increased the wingspan ever so slightly to 750mm. I used 2mm correx and so had to change things here and there to make things fit together from the original 5mm foam used.
I also had some carbon DIY pushrods from a previous plane that I managed to get to fit here as I knew it was gonna be fast so I wanted maximum torque from my cheap 9g servos.
Final Config:
Motor: 2212 - 2700kv with a 6x4 prop
ESC: 40A
Lipo: 3S 1500-2200
6mm Carbon rod infused in a 3d printed wing spar
Printing:
I decided to print the powerpod, wing spar, ailerons, elevator and rudder since the scallops are a bit tough to cut perfectly out of correx. Since Correx can go in the sun I wanted to use a filament that can go in the sun. Std PLA is heavy but prints so great, ABS is lighter but a bit harder to print. However, I just couldn't get a stiff enough flat part without going to crazy weights even with ABS. I eventually settled on around 20g for each aileron, 33g for the rudder and 25g for the elevator. Gyroid infill. Anyway, this ended up being way too tail heavy. I hoped I could put my battery all the way forward but to not avail. It was not enough. I ended up using 80g of lead in the front to balance out that rudder and elevator on my 1500mAh lipo. Total AUW 780g.
Maiden flight:
Initially I used an Emax 2822 - 1200KV to maiden the plane, but as it was so heavy it was barely flyable, I couldn't get it to go 3 mistakes high. It needed full power to stay up.
Ripping off the rudder:
I decided to replace the ABS rudder with a correx one (33g down to 7g + bbq skewers for stiffness - say 11g at the max). I also swapped the motor for a heavier 2212 - 2700kv unit and since its way up front, it will help with CG. I still ended up needing 40g nose weight. I also halfed the powerpod since all the electronics were unfront anyway lol... This brought the nose weight requirement down a tad again. I am roughly now on 670g AUW with a 3S 1500mAh, maybe a tad lighter. Still a decent amount above the suggest 510g by FT, however, I do have 315w of power.
Re-maiden:
Like a bird on roids! She's quick, super quick. Unlimited vertical and oh wait battery flat... Yup, 3min flights are a push. My 2200mah gets me about 4min but its an old lipo so theres a difference in power, I can feel it. Otherwise she flies great. Something to get used to.
To Do Still (Hopefully before this weekend):
I am gonna rip off the ABS elevator and put a correx piece in. Should allow me to get rid of the remaining 35-40g of lead up front when on my 1500mAh. I also want to give it a a paint job as the correx white can get hard to see in the clouds.
I have three 6x5.5 props in the toolbox... I know I shouldn't use em on this. I know. Right? Too much. Yes... Too much. I already have 315w with my current 6x4... but I do want to see what it'll do lol.
Hoping to get an updated video this weekend as well as some newer pics.
Heres a quick video from last Sunday at the field before the rain came, unfortunately this is with the 2200mAh so not as quick as my newer 1500mAh. No lead needed with 2200mAh.
