First trial of DIY cable cam in Sulham Woods
CABLE CAM MAIN PARTS LIST.
Speed Controller RCline SP-RF20, an old 20A Brushed Motor speed Controller for cars. Runs very cool with the 15T gear below, runs quite hot with 40T gear, the correct gear for this motor/ESC set up is probably somewhere between
If you can't find these then go to your local modelshops and buy a motor/speed controller combination . Tell them the weight of the rig and load , what speed you want to travel at, your intended gearing, and they should be able to advise the size you need
Tx and Rx 27MHz system from and old Traxxas RC Car.Try to use a 27MHz system as this is better in amongst the trees than a 2.4GHz set up.
Main gear TREX 450 helicopter main gear 150 tooth
Motor pinion gear 15Tooth Trex 450 gear will give you around 15km/hr, a 40T pinion gear will give around 40km/hr, that is what is pictured
Pulleys 60mm ‘R’ Groove – nylon pulley wheel C60-10B these have a 10mm bore and will take up to a 10mm dia rope. Cut a 10mm piece out of a cycle inner tube to give grip for the driving pulley.
Video Tx There is a video Tx attached to the front for live downlink. It is an ImmersionRc 2.4GHz version, works OK with this system because I am using 27MHz for RC, if you use 2.4GHz for RC , you can use a 5.8GHz video Tx from ImmersionRC. See firstpersonview.co.uk/ for set ups
