Aerotech make a G12 in their RC range, but in the 32mm hardware.

Also available for the same hardware:
F13, F16 and F23.
To get a 'G' size with KNSU you will have a considerable weight gain. The E6 'equivalent' I modelled in BurnSim needed 36g of propellant(max that will fit in a 24/60 case) for ~35N total impulse, with optimum KNSU(ie, cooked)
Compare that to the E6 which has 22g propellant in a 24/40 case for 37.5N total impulse. A 63% increase in propellant weight and the 24/60 hardware weighs more.
The AT G12 has 51g propellant, so KNSU 'equivalent' would need ~83g.
If you're into competition flying you're at a disadvantage. Sport flying it might not bother you... |
