Re: Volvo A40F articulated dumper
Great cinema. Good idea too turn with cti cylinders. I think it's an option for my next Volvo-dumper.

As regards the CTI cylinders, they can be a bit hit and miss and I can not yet figure out why they sometimes do not work. Some days they work without a glitch , other days they suddenly stop working intermittently. Each cylinder piston is capable of 4 kg push and pull , that's 8 kg working together which should be more than enough for steering. I am running them on 3 Cell lipos but I am tempted to try 4 cells . |

Re: Volvo A40F articulated dumper
A really nice model. Dump system speed is very prototypical and smooth. I don't have any personal experience with the CTI cylinders but have seen them used in a variety of applications. Let us know when you find out what is causing the occasional problem.
Love the sound system and lights! Ken

Do you mean O rings installed on the piston shaft so that each shaft can not be pulled completely into the cylinder? Also is the Thor 2 BCD speed regulator ESC good enough or do you have better experience with another ESC type for parrallel CTI cylinders Thanks for the great advice. |

Another option is this one. http://www.cti-modellbau.de/CTI-Schaltmodule/-154.html With limit switches, you can limit the way and with this switch module you switch on minus the knob. If the limit switches are set correctly, the cylinder no longer drive fixed. I would recommend it but only with the O - try wrestling. Manfred |
