Hi there,
I will be getting a Rattworks I90LH "Yardstick" hybrid motor.
Can anyone tell me any real world experiences that they have had?
What do you use as the ignitor grain? Is there any particular variation with
different propellant types as the starter grain? Has anyone tried a different
method of lighting them? Yes, I know that it is only a TRA approved motor with
the manufacturer's reccomended ignition methods.
