A few of us had a kinda sorta contest to come up with an RC version of the $10 Wal-Mart foam glider called the Raptor......I decided it needed to be a twin, and now sorta looks like the TU-95 Bear....but with only 2 motors....so it's called the TU-47 1/2 Cub.....Started on it Monday....waiting on CW/CCW props and 20A ESC's....but that's why I like to mess with foam....motors are 2200kv Grayson Mini Jet, 4.75x4.75 props and a 2200 mah 30C 3S.....we'll...Continue Reading

No complaints

Motor: Powerforce G15 (LC3542/6T) 920 kV 42A max 36A load
ESC: 40A
Batteries: 3300 3S or 2200 4S
Prop: 11x6 (ESC gets a little hot) probably change to a 10x6
Servos: Towerpro MG90S Micro

Post maiden notes:
1. PLENTY of power (4s)..unlimited vertical at FT.
2. Plenty of aileron and elevator control....dampened with 35% expo and 80% travel adj in trans.
3. Not enough rudder....already changed.
4. Less than 10 deg of flaps and she'll all but stop in mid air....
5. She'll land dead stick with ease..no tip stall...she'll land even slower with flaps....
6. Good sport plane with a 3s....unbelievable with a 4s.......and I'm sold on sewn hinges !

Scratch-built Foamie Contest Build - Einzpfeil 2.0 - Proof of flight...sorry for losing sight of her occasionally. I was busy watching the airplane and not the viewfinder....she's plenty fast and maneuverable...though I don't have the stabilizer gains set correctly....she'd flutter with the stabilizer engaged, but only at full throttle.....

After a few tweaks..........Was nervous about flying her, but after big Al told me she's easy to fly, I flew her the rest of the day......
I'm pleased.....the goal was to develop a more aerobatic aircraft , and she seems capable of just about anything

Here's another one off that I built for BBCC 3 (almost 2 years ago) and never flew. She was underpowered and tail heavy.....I fixed that and flew her for the first time this morning......she's another one of my one off's that has never been kitted..as far as I know this is the only RC replica of the original......

Doppelpfeil 1.0 Maiden (1 min 45 sec)


She's a handful..working on Doppelpfeil 2.0.......

flew her 5 times successfully..it was that "Oh let's put her up one more time" that killed her....got her in the sun, lost orientation, and she went in hard....BUT..the foam board crumpled like the front of a Mercedes, saving all the electrics........

This is for all the guys on RCAAA......you know who you are !

I've decided to try to build a 3D-ish foamie......so I stole the stuff I liked from 4-5 ARF's and came up with this....takes (2) sheets of 3/16" Elmers board and a 2 liter bottle for the canopy.....I'll revise and annotate once I build her, but you guys get the idea......As always, drawings are on 36x48 paper.. foam board blanks are 40x30.

I did a box fuse because I don't like batteries, ESC's, and Receivers flopping around in the wind !

This ain't Dollar Tree foam !
