The ZULU Trainer Canopy

June 23rd, 2010 RobZULU 2 comments

The ZULU trainer is an extremely light-weigth and durable canopy for the Walkera 4G6 / 4#6. At only 2.4g (0.85oz) it offers a significant weight saving and performance increase compared to the stock canopy.

4G6 / 4#6 prototype canopy

A new canopy design for the Walkera 4G6 / 4#6. With inspiration from the Henseleit MP and Three Dee RIGID canopy, I made this canopy longer and tightly closed around the swashplate.

Its easy to put on and uses the original rubber grommets and canopy mount.

And the best part: at 3.5gm it’s even lighter than the original canopy. Here are two pics one of the first prototypes. Still working on the colors and decal sets.

Flybarless Walkera 4#6 / 4G6

Flybarless Walkera 4#6 RX2433

Flybarless Walkera 4#6 RX2433

The rumours have been around for a while, now we have the first picture of the new 3-axis gyroscope RX from Walkera. As per nanoheli.net the flybarless version of the 4#6 will be called 4#6S. A flybarless 4G6 is said to be in the making too.

Fits into Walkera’s platform strategy
This development fits into the Walkera’s platform strategy, in which several models are based on mostly compatible components. The collective pitch 4G6 and fixed pitch 4#6 of FP based on largely interchangeable components. For the flybarless versions merely a new rotor head and receiver will be necessary.

Megatrend flybarless

It looks like the flybarless trend is finally moving into the sub-micro area. We will see if Walkera’s 3-axis sensor RX will deliver what is expected. Besides the quality of the sensors, the software will probably be the deciding point. Whether there will be corresponding update options – we have to wait and see.

The mysterious 5th servo port
It is also interesting that there are 5 servo ports seen on the RX2433 – for the fixed-pitch 4#6 however, only 4 servo ports needed. So what’s up with the 5th port? Is it a programming adapter or is this RX also a prototype for a CP version with the required 5 servo ports?

4G6 / 4#6 pitchslider, chinese weights preview

February 20th, 2010 RobZULU 3 comments

Just got some very nicely machined parts from Hardy, including the new pitchslider and plastic baldegrips inlays. Now there absolutely no play in the pitchslider anymore. Here is a video of the double-bearing pitchslider, i also have a single bearing version which is lighter but has a little bit of play due to the use of only one bearing.

I have also installed chinese weights on the bladegrips which reduce the force needed to pitch the tailblades dramatically.

Walkera 4G6 with HK-250 GT tail rotor grips

Walkera 4G6 with HK250 tail rotor grips

Walkera 4G6 with HK250 tail rotor grips

Just tested the Walkera 4G6 with HK-250 GT tail rotor grips and hub. Very nice!

The HK250 tailshaft is 2mm so i had to use some shrinktube on the 4G6 tailshaft which is only 1.5mm. I removed the hub from the original Walkera tailshaft. With shrinktube, fit is perfect and secured by a grubscrew in the hub.

The Walkera metal balllinks have been epoxied into the bladegrips. I also made some new 1mm CF tailblades with sanded airfoil. Had to use a little piece of 0.5mm CF as a space as the HK-250 GT tailblades are 1mm.

Additional weight is 1.2 gm. Result is a perfectly solid tail. Only drawback is that the pitchslider trave is slightly reduced (by about 2mm), resulting i slower piro rates. I might make a custom tailshaft from 1.5mm steel which is slightly longer than the original walkera shaft.

Now i only need the new pitchslider from Hardy and this will be the perfect 4G6 tail.

Also with Hardys blade grip mod (inlays) i will do a direct comparison between the modded Walkera plastic bladehoders and the HK-250 GT parts.
