Blade mSR Short Arms Swashplate Mod 2

Solutions is always more than problems. The blade mSR swashplate mod with shortened arms mentioned earlier does work, however, here is a shortcut for it! This modification will improve your heli as good as previous Shortened Swashplate Arms Mod, in the way that enhancing more cyclic throw and response.
The idea is simple, just replace the stock swashplate with 4#3B metal swashplate! This is how it looks like after mod.

Watch how it fly indoor first!

Guides of short arm mod

This is the 4#3B metal swashplate, which fits the mSR stock swash hub.

Drill and screw an anti-rotation pin which is come from a servo link rod. Then remove the unnecessary swashplate arm.

As 4#3b and mSR swash bearings’ size are identical so we can mount it to mSR stock swash hub. And you can see the arms are much shorter.The weight of 4#3B swashplate is 1.4g which is 0.1g heavier than the mSR stock one.

Difference of swash plates

The stock mSR swashplate has a very unusual pivot point to ball joint location. The ball joint is actually lower than the pivot’s plane thus the ball joint tilt is actually moving upward-outward. This means as you tilt the swash higher the swash deflection becomes smaller and it is not linear.

Unlike a 4#3B swashplate, the ball joint is actually on the same plane with the pivot thus movement is almost linear on any direction thus providing you a bind free and a linear tilting swashplate.

After swapping the mSR hub to the 4#3B swashplate base, the ball joint is near the same plane of pivot, so offering a natural and close to linear tilt.

After Mod

Following are some photos showing the after-mod mSR.

Some people may think 5G6 swash maybe even better, since the arms are even shorter than that of 4#3B swash. But it may result in binding on the rotor head if the arms are too short.
