Barry,

I did not go with redundant anything. The only thing I did extra was to install the smart-fly opitical kill it weight a total of one ounce and if you have throttle servo trouble it gives you a way to kill the engine in the air if you do not have a choke servo

I always say do what make you feel best. While Hoss knows what he is doing, sometimes you canot get to wild with things.

Here is my complete setup. My personal preference is no redundancy once I get below a 50cc plane. This plane is not really a 50cc, I'm just using one for it

DA50
22x8 PT models CF prop
Fromeco 2400mak Li-ion on the igntion
Fromeco regulator set at 5.2 volts
Fromceo Badger Failsafe Switch
Smart-fly optical kill for the ignition
JR2000 Scanselect receiver
Fromeco 4800mah Li-ion for the reciever
Fromeco regulator set at 6 volts
Fromeco Failsafe Badger switch
Hitec 5945's all around
SWB dbl lock control arms
Dubro ball links on the servo arm
Dubro Kwik lok safety links on the control horns
H9 Titanium control rods

A lot of the above is overkill but that's how I like things. The Failsafe switches are electronic so there is no moving parts, if they do fail, they fail on not off. There is no choke servo as I have a nylon rod connected to it pointing to the front so I can just pull it to choke it then push it back in to open it.

Total weight according to my Escali scale is exactly 14lbs 4 ounces, I just weighed it. Wheel pants are not installed but I am going to do that since I have more than enough power now so add about 4 or 5 ounces
