The perfect addition to your small electric helicopter. 325 blades perfect for T-rex 450 or similar size helis. (315mm bolt hole to tip)
Radix 325s are perfect for the T-rex 450 and similar sized helis. In T-rex terms they are 325mm length (tip to tip) 315mm bolt hole to tip (standard blade measurement). They are a great balance of lift and control rate.
For an aggressive 3D setup we recommend running at full control extremes (maximum pitch range and cyclic ranges). This will give a lively yet very stable feel. Even in hard 3D they remain quiet and are hard to overload with extreme controls.
