Cause of Right Tilt and Left Turn Problem

The left turn issue in my opinion is just a nasty side effect of a very lightweight FBL FP, youll just have to learn to fly around it.

Yes! There is only so much the FBL system can do, and to get the level of performance in a heli this size is impressive. It's easy to lose track of how far these things have come in the past couple years. Just watched an old episode of Mythbusters where Grant tried to fly a tiny (by the standards of the day) FP with nicads. I for one am happy to have something like this.

Flight wise, the msrx is awesome. Especially when you compare it to the other FBL FP ultra-micros out there....oh wait, its the only one! (get some Walkera!) This whole left turn issue has never surfaced because there has never been a heli like this..therefor WE are on the front lines of learning the tendencies. Much like when FBL system hit the market and that one poor bastard that stuck his 450 in the dirt on the maiden flight because he gave right ale BEFORE he lifted off

Some systems just take a different approach.

+10,000 I love being at the forefront. w00t!

Walkera has a flybarless micro as well, actually had it for while before the Blade mSR X.

It is the V100D01.

A spinning motor must also induce gyroscopic affects. What happens when you put a tiny gyroscope to one side of a heli and not the other? Are there any other helis that have off-center motors? I can't believe that the degree of tilt and the absurd difficulty of left turns is normal, or the odd assymetric design is coincidental.

The tilt is normal... for all helis. Look up 'Translating Tendency'.

"In our conventional anti-clockwise rotating helicopter this is sometimes referred to as the 'left skid low tendency'."

Thats closer to mcpx size though (well, maybe not so at 240+mm rotor span?), where talking msrx size. The new micro CP they just came out with is msrx size...but it dont count, being cp.
Blade span:
V100D01= 202mm
msrx= 181mm

21mm is quite a bit bigger with a heli this size.

I would say the main physical difference is not in size but in weight.

V100D01
1). Main Rotor Diameter: 202 mm
2). Tail Rotor Diameter: 48 mm
3). Overall Length: 216 mm
4). All-up Weight: 66g (Battery included)
5). Tail Motor : WK-WS-10-002
6). Main Motor : WK-WS-12-003
7). Tail Speed controller : WK-WST-10A-LTC

mSR X
Type: Electric Flybarless Single-Rotor Fixed-Pitch Helicopter
Main Rotor Diameter: 7.13 in (181mm)
Tail Rotor Diameter: 1.46 in (37mm)
Gross Weight: 1.09 oz (31 g)
Length: 7.44 in (189mm)

More than twice as much!

However the main difference overall is flight characteristics!

The V100D01 does not fly as easy right off the box...

AWESOME!!! One of the one things from Heli-MX school I remember

I moved the battery to the left side of the helicopter, now left turns are as smooth as right turns. Try figure 8's before and after. It looks like there is enough room to mount the battery inside the body on the left side which would look better.

for those that say the mcpx dose not lean look again mine dose and my to larger Gasser's do also
