I am sorry that the instructions for how to use the water stuff was not included in the manual. Not sure how that did not make it in as it was in the beta versions of the manual, also the manual I got with my copy has in there that it requires SP2, but Acceleration was recommended (due to MS incorporating multi-engine helo's). Seems like some things got lost in translation between our copy, and the final retail release.
How to use the fire fighting equipment: First you need to go on the center console (right seat side) and on the right side of the center console set the hoist master switch to one of the 3 positions (pilot, co-pilot, aft pilot). For this we will select pilot, and that will enable you to use the panel on the right hand side of the center console. From there you use the cargo release mode switch, and select one of the other positions. If you select Shear that drops the water, and so forth. Then you go on the forward right hand side over head and arm the shear switches and then the water will jettison. To get the water to stop/retract water suckers you just move the switch back to safe position, and turn the hoist master switch off. Sorry for the confusion and anyone who wants screens/video tutorial of it we will be more than happy to do it. Thanks for the comments, and for trying the product.
