Flybar Weights, Head Dampening Shims And Fine-Tuning Cyclic Response - E-flight Blade SR RTF Airframe Instruction Manual

Flybar Weights, Head Dampening Shims and Fine-Tuning Cyclic Response

Your Blade SR is equipped with two sets of flybar weights that are secured in both the outermost position against the
flybar paddle and the innermost position, closest to the head/main shaft.
Note: The innermost collars are used to secure the paddle control frame and should not be moved.
In the outer position, the weights help provide added stability by increasing the amount of cyclic input required to
overcome the gyroscopic force of the flybar paddles. In general, flying with the weights in this position will still provide
good cyclic response, but with reduced sensitivity (especially when in hover), when compared to having them positioned
closer to the head/main shaft on the flybar. We suggest you make your first flights with the flybar weights in this
position before making any adjustments.
If, after the first few flights, you feel as though the cyclic response is too quick, we recommend moving the inner set of
weights out, next to the outer set. With both sets in the outer position, the cyclic response will become noticeably less
responsive.

If, after the first few flights, you would prefer to have even quicker and more aggressive cyclic response, you can
reposition the outer flybar weights so that they are closer in to the head/main shaft on the flybar. It is usually best
to move the weights in only a small distance at a time before making each subsequent test flight, until you find the
position at which you prefer the cyclic response most.
Note: It is important that the weight(s) on each side of the flybar be positioned at a distance equal
from the head/main shaft in order to prevent imbalance that could lead to vibration in the
rotor head.
Dampening of the rotor head (main rotor blades) can also be adjusted in order to fine-tune the cyclic response of your
model. In general, stiffer dampening will result in quicker cyclic response. The dampening of your Blade SR has been
set to provide good stability right out of the box, and we suggest that you make your first flights with this amount of
dampening before making any changes.
If, after the first few flights, you would prefer to have quicker cyclic response, you can stiffen the rotor head dampening
by adding shims between the O-ring and step washer on each side of the center hub (see the "Exploded View" drawing
and parts listing for reference). Head dampening shims are available separately in packs of eight (EFLH1144); however,
you should install only one shim per side at a time before making each subsequent test flight, until you find the
dampening at which you most prefer the cyclic response (and stability).
Note: You must always install an equal number of shims on each side of the center hub.
Note: If you install too many shims, and the dampening becomes too stiff, the helicopter can wobble and shake
in flight. Take care when making testing flights after adding shims to prevent crashing the model as a
result of a wobble or shake.
