    CH Products Pro Throttle Resistance Mod

    I bought a Ch Products Pro Throttle a few weeks back....I wanted one for a while as they looked very no frills and good quality..right up my street...Anyways apart from the fact there are no pots on it (which is a major big bug bear to me when you have a throttle of that quality) the main problem with it was its loose throttle slider....I would be in a dogfight and then realise that I was only on half throttle as the resistance in the throttle movement was so slack I wouldn't even feel it sliding back especially when my mind was preoccupied in a fight...I couldn't find a fix for this on the internet anywhere although I did find forums where folks had complained about this problem.

    So I decided to strip it and have a crack at getting some resistance in there which I did successfully by adding 2 thin strips of sticky backed velcro into the slider.

    The interior of these throttles is suprisingly basic and so this mod should not be a big problem for anyone who could wire a household plug.

    Here is a break down for those that want to do it....:

    A Good Tips: Firstly you may want to use your phone camera to get shots inside the unit as you take it apart so you have reference when you put it back together. I tend to do this these days with anything I take apart for the first time , especially electronic stuff.

    Also, its a good idea to get a dish or something to put screws and small parts into so you are not losing them around your work area or accidently brushing them onto your floor.


    1) Take off the 4 rubber gromets from each corner of the underside of the base with a small flat screwdriver.

    2) Unscrew the 4 screws from each corner and take the bottom off the unit.

    3) Unscrew the 6 screws that hold the slider cover being carefull not to damage any of the wiring.

    4) Gently pull off the potentiometer throttle paying attention to the small piece of plastic that is friction stuck to the underneath of the arm. This should slot back between the 2 uprights at the one end and acts as a resistance to the pot action.

    5) Unscrew the 2 screws on the centre of the slider which attach the grip on the other side.

    6) Cut 2 strips of sticky back velcro. IMPORTANT you only use the fluffy (loop) side and not the rough (hook) side. The pieces should be around 6cm by 1cm.

    7) Gently pull the slider away from the base keeping all the wires intact. Secure the 2 pieces of velco either side of the slider and between the 4 slider skates so that when the unit is put back together these 2 will be on the top of the slider causing friction with the base top (as in the image below). Push the velcro down especially around the edges. You do not want any of the sticky on the Velcro to come into contact with the underside of the top body housing when compressed.



    8) Screw the unit back together in reverse to the way it was taken apart. Make sure that the plastic piece resistance block that goes under the throttle pot lever is secured between the 2 uprights at the end of the push fit top. The pot and lever is a pushfit and will be secured by the halves of the unit when it is put together.


    This mod worked for me and added just enough friction to the unit to keep it from moving unless I consciously moved it myself. You do not want it to jam or be too stiff. You could of course add more of less Velcro to create more or less resistance as preferred.

    Hope this is of use to someone...~S~

    Update - I have had this mod for over 2 years on my CH Products Pro Throttle with no noticeable negative difference in the performance. The mod seems to be as bullet proof as the throttle itself.
