Perfect fit for eflite Radian ,add a VM 11x7 with this and you have a vertical climbing rocket with the stock motor .
10 seconds of climb is enough with the stock motor.

This spinner fits the e flite radian perfectly ,teamed with a vladimirs or gm prop ,makes an excellent climb improvement.
Need to buy a 4mm collet to use it on the stock Radian motor,
