Just joined this forum, but haven't seen many posts about the ACT system on the SC. My SC will be here tomorrow and I have heard mixed reviews regarding how well the ACT system works. Am curious to see if it really works. ;D

the act system works by compairing the differnce in color, or brightness of the two sensors. the problem with this is if you fly over something lightly colored like sand or concerte it will confuse the system and limit you control. its a good idea just not implimented very well. your best bet is to check all your control surfaces and make sure they are level, make sure the wing is on stright and check your center of gravity before your first flight. when you take off make sure its into the wind and let the plane climb a good bit before trying to make any turns. remember altitude is your friend as it gives yu time to correct mistakes, and with the cub most mistakes are easly fixed by letting go of the stick for a second then gently fly out of the problem, over correcting is you enemy

In the perfect enviroment it works. Unfortunatley I have not heard of anyone finding the "perfect enviroment". Such a place will have nothing but grass on the earth and nothing but sky in the sky. I senses heat......

Work?  Why yes - to your demise. The only one's that believe in ACT are newbies and ParkZone. ACT works by using sensors looking at the ground and horizon. It differentiates shade (dark ground/light sky) and tries to keep them that way. If the plane goes up or down too fast and the shade isn't right it 'takes control' AWAY from you and essentially neutralizes the controls. You can achieve the SAME result just by letting go of the sticks. Of course new pilots don't they just over correct some more. The high wing Cub will self correct in time but not immediately. If ACT kicks in up high, no problem, but then letting go of the sticks would work also. If it happens down low you have NO ABILITY TO CORRECT SINCE CONTROL IS REMOVED! Just like letting go of the sticks once you pointed it straight at the ground from 20 feet up it's going in! Its not useful down low and wrecks more planes than it saves, but it sure sounds good to new fliers. Since they can't fly anyway and they wreck anyway they figure it would only have been worse without it. They can't differentiate between their short comings and ACT's problems. So it works up high where you don't really benefit from it and screws you up down low when it doesn't help. It also gets totally confused when you fly over water, snow or very light ground surfaces (light concrete, sand) since it doesn't know what to do with that. It's NOT SMART, it's just a shade sensor. What it does best is lure in new fliers. Great marketing scheme. |

Work? ACT works by using sensors looking at the ground and horizon. It differentiates shade (dark ground/light sky) and tries to keep them that way. Are you sure? From what I read a while back it used heat/cold. The earth is always warmer than the sky....except in a few situations like over water, snow. If this was true (the shade thing) then night flying a stock cub with ACT on would be impossible. Might have been for a co pilot system that I read this about,.....not sure. Kevin |

;DJust maidened my SC and I unhooked the ACT before launch...didn't need it..flew it twice...2 easy landings and no damage !!! Spent abou 2 hours on Clearview prior to flying. I'm back !!!! More power !!!!!!! ;D ;D

I will second the opinions expressed above. Most beginers like to fly at low altitudes at low speeds. The ACT system blows up the @#$ in this environment so its pretty much useless.

THE ACT SENSES light to tell the diffrence in up and down the Some others like the co-pilot use temp to tell up and down.

Rip the sensors out and throw them away before your first flight,I didn't, shame on me.Like I've said before,they should offer the SC without ACT at a reduced price,,get more people in the air!! And yes they are light sensors,simple photo cells,,,very simple!

As a complete beginner, I found the ACT amazing. It never at any point messed me up and only helped until I was more comfortable flying without it. But, everyone is different, as you can tell by so many different opinions.

The Firebird Phantom and the Supercub both have ACT. Both systems do nothing but cause problems. I've both, and permanently disabled all aspects on both planes.
The sensors are simple photocell. It only works if the sky is light and the ground is dark. White snow, light concrete, or reflective surfaces will all confuse the ACT especially under a cloudy sky.
It may work for some in perfect settings, but never anywhere I fly.

The ACT is a lot more trouble than it is worth IMHO, when I got up in wind with it on by accident ( dumb did not notice the Tx switch had been bumped to on) induced a vertical oscillation that I could not recover from. After repairs and disconnecting the sensors am fine. With sensors disconnected, the Tx switch acts like a dual rate switch, ACT gives less control surface throw than ACT off so I fly with it off, but at least with the sensors disconnected the system does not try to take control of the plane away from me.
