Making an "Ugwi Stik" out of a sig Kiwi.........

Read through the instructions and reviewed the plans...here's what's going to change (so far) : Inboard third of the wing will be flaps, outboard two-thirds will be ailerons cut from 3/16 sheet.....all scalloped. Same for the stab. Wing tips will be built-up to match the Stik's wing. Servos will be wing mounted. Wing will be built one-piece flat or with just a touch of dihedral. She'll be built as a tail dragger with a steerable tail wheel. Since she's going to be electric (GForce G32 Brushless Outrunner Motor (4250-800KV)) the firewall and motor mounts will have to change, but I'll wait until the motor arrives to make those changes....the rest of it is pretty straight forward......now, where are my X-acto's ?...Continue Reading

Smaller airframe......bigger fan

OK....here's how we set the rates and expo:
Ailerons:
R=30/E=20, R=45/E=25, R=70/E=25...flew the ailerons on low rate
Elevator:
R=40/E=25, R=60/E=25, R=80/E=25...flew the elevator on mid rate

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
Receiver: Lemon 6 channel mini (DSMX/DSM2)

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
