Dry Chemical is terrible on these models !!! Send that turbine in and youll probably need a complete rebuild, as dry chem is corrosive. The chemical itself is monamonium phosphate w/ a urea base to prevent clumping. if it got inside the Rx, or any of the ECU componets youll need to get those looked at also. when it sits on metal it will corrode it quickly, not like a strong acid, but what would normally take years will take weeks. I would get everything out electronic that you can, and you probably would want to look @ your gear and air systems also. If there is chemical on it blow it off. What a headache for a moment of panic !!!

Halon is # 1 but expensive as all get out to recharge. No residual and no reactive properties as it disperses quickly. Heavier than air so it will hug the ground in a release.

CO2 is probably the best for the hobby. inexpensive, and reaily available at most welders supply, or any where that deals with gasses. its only draw back is the temperature it comes out of the cone at and the fact for that nanosecond the watervapor it attracts. other than that no other complications.

Dry chem..... well only if you have to if your going to lose other property because of your fire, and the whole Jet is already written off.
