Alpha Jet Replacement
This unit is very light puts out a lot of power when coupled with a Mega 15/3/6 motor. The tabs connecting the motor mount to the duct unit are a little flimsy and are poorly mounted to the motor canister housing and well as the duct unit. If unit is being enclosed in an airframe it shouldn't be a problem but if exposed the unit's integrity could be compromised.
I give this product 4 stars. Review by Groden, Mark
