The lady is flying. 100mAh lipo, Walkera 5G6 4-1, servoboard mod proportional tailmotor for 3rd channel. 6:30 flighttime. Based on the famous IR Toy Airwolf helicopter. Build log here.
lil’ demo in the livingroom with my modified Walkera 4#3B helicopter: backward circles, piros etc.
CQE Flash carbon blades, bell head mod (see my post here), ADH50L / XP 7A 20T pinion, 2.9g tail / flea, RX 2406B.
Ok, it’s not new (from Jan. 2009) but what Gabriel from Brazil does is just amazing. Incredible. Not legal in Germany probably. Filmed on location in Rio de Janeiro, Brazil – most amazing set – Gabriel isn’t shy to show fly-through-tunnels, fly-through-windows and other crazy stuff in this best of. Probably a 1~ GHz setup with lots of mW’s…
So to me its the best FPV vid ever – or show me something better!
marc on RC Groups showed us this FPV PicooZ. Now check this out, Prox Dynamics (i blogged about Prox Dynamic’s FPV heli here)!
Marc and his FPV Picooz
Before I start: This mod really does make a huge difference. It will make the 4#3B helicopter responsive like never before, self stabilizing and not rolling in any other direction than your stick input. See my videos here.
But only if the flybar angle is set exactly to 45°. If its not, you will end up with the same performance as in the known Bell/Hiller Mod or the other available b/h mods with the original 90° flybar. However with this mod the flybar angle can be set. I’m working on an improvement in how to set the angle exactly AND have it stay that way (thinking liquid metal, loctite, epoxy, bigger screw…) Maybe someone will come up with the perfect solution.
Bell Head on the Walkera 4#3B
Mod made from stock parts. The flybar angle can be set between exactly to any angle around 45° (+/- 10°). The result is pretty much what the Walkera CB100 will be like.
With this mod, the left-rolling problem of the well known 4#3B Bell/Hiller mod is eliminated because phasing can be set exactly. More about parts and how-to later.
UPDATE: scroll down for a 10 seconds hands free hover video.
First step towards building a brushless direct drive 2.4Ghz gyro-ed PizooZ. The shaft of the HP03T 2.9 BL outrunner was replaced by a 50mm 1.5mm shaft that holds the picooZ main rotor. The picooZ rotor head was drilled to 1.5mm (stock is 1mm). The HP03T is normally used for the Walkera 4#3B brushless tail conversion. The motor is power by the flea converter.
Thrust at mid-stick is about 20g – about right, remains to be seen if the revomix works out.
I’m aiming for about 15g AUW for the 2Ch – if it works as planned this will be the platform for the acutator cyclics mod (see post here).
Amazingly quiet!
Just did the first testflights with the Airwolf coax helicopter – made from the well know RC toy heli, the IR, 3Ch Airwolf.
inside look: Airwolf 3 Ch 2.4GHz gyro-ed
The electronics were removed and replaced by a Walkera 5G6 4 in 1 (RX2402) which has 2 brushed motor outputs, 2 servo outputs and an onboard gyro. The 4 in 1 goes into the body quite nicely – only little cutting was necessary.
The heli is now powered by a 50mAh Zippy lipo – maybe a 70mAh or even 110mAh will also do.
Because of a broken rotorblade tip i had to cut the blades back – not good, because lift is decreased significantly – now im waiting for new blades.
The third channel is used to controll the vertical tailrotor. This rotor achieves forwars and backward flying. The motor is powered via a servo board (PCB) which instead of driving the servo motor drives the tailmotor.
IR Airwolf RC Toy: 23.1g AUW, 4:30 flight time
Original IR Toy specs (measured)
Two new vids of the Walkera 4G6 prototype are up on youtube since yesterday. It is said the heli will be available at the beginning of september.
The first one with some basic flying, backward circles and figure eights – the tail looks rock solid. Very nice.
nice!
The second one – inverted flying, flips and rolls.
RC Groups User marc31 just presented the first brushless conversion of the PicooZ. The mod is based on the 2.4 GHz Walkera 4#3B 4-1. The cyclics are controlled by actuators.
