For my summer project this year, im building a remote controlled boat with a trimmer engine. a Q about servos?

how high of torque servo do i need to buy to be able to pull the throttle cord? (in kg/cm please?)For my summer project this year, im building a remote controlled boat with a trimmer engine. a Q about servos?
Get a spring balance and measure it. (In 'real' science and engineering that's also known as 'empiricism' 鈽?

There's generally just a little spring in the carb to pull back on the throttle; It shouldn't be much, but you can also weaken the spring.

Changing the rotation of servo's in Radio Controlled Car?

I recently put together a RC (Radio Controlled) nitro powered car. I have just noticed one major problem. On the controller, when I turn left, the car turns right! I don't know if it is because I put the servo' in wrongly or what. What can I do about this? I hope I dont have to take it all apart and redo it! Is there a way I can change the rotation of the servo's in the car without taking it apart?Changing the rotation of servo's in Radio Controlled Car?
hold the remote upside down! =) no jk. i don't know exactly how they work, but i expect that if you reverse the polarity of the motor that turns the wheels, it will switch it around. try that and update if it doesn't work.

I have a radio controlled car model, i tryed switching to another steering servo. still unresponsive any ideas

What transmitter and recievers can I buy to control 4 different simple servos?

I have 4 bird launchers for dog training. All have the servo/ electronics built in. They are made to buy a $700 system from dogtra or tri-tronics, but i know i can do it for alot less with another transmitter and reciever. Im sure it is very simple considering the servo only triggers the release mechanism. I need a battery operated system that can be controlled at a maximum distance of about 700 feet. What should i buy and is it easy to hook up to such a simple servo?What transmitter and recievers can I buy to control 4 different simple servos?
a radio controlled airplane transmitter would work great check out a local hobby store or one of those nice radio controlled cars that have a 4 channel system check out futaba

How should I adjust the servo-motor cables (controls exhaust/intake valves) on '02 CBR954 RR,for hi-r.p.m. HP?

I want to adjust the servo cables for the intake and exhaust valves so that they open/close at the optimal RPM to make the most power in the high-revs? I want this to be approximately 7000-12,000 rpms. I do not have a power-prgrmmr or such, but do have a K%26amp;N filter, FMF silencer,hi-per cltch and 1 tooth smaller front sprocket.





Are there any certified-Honda Tech's out there to answer this???How should I adjust the servo-motor cables (controls exhaust/intake valves) on '02 CBR954 RR,for hi-r.p.m. HP?
there are no cables that open or close your valves they open and close via the camshaft the servo motor in your exhaust is not adjustable period do not mess with your bike you haven't a clue to how it operatesHow should I adjust the servo-motor cables (controls exhaust/intake valves) on '02 CBR954 RR,for hi-r.p.m. HP?
From your question it sounds like you are confused about the variable exhaust valve system. The valve in the exhaust system which is controlled by the bikes computor and moved by the servo motor and cables has NOTHING to do with the engine exhaust/intake valves. As far as I know there is no optimum power setting or tuning to it. You simply set it as described in the manual. After removing the lower part of the fairing you can see the lower pulley, there are dots on it. At idle to a certain engine speed the pulley is in one position. As you rev the engine the pulley changes to two other postions through the rev range (I can't remember the RPM shift points). You simply change the cable adjustment to make sure the pulley travels to the correct position when it changes, there is no majic setting. If fact most aftermarket exhaust systems simply do away with the valve which tells you that it is really not all that effective anyway.
geo46er explained it perfectly.

Do the amount of channels on a r/c radio relate to how many servos it can control??

exactly... a 2 channel radio can control 2 servos. Typically for cars and boats. 4, 5, 6 and more are typically used for planes and helicopters.





However, you can contorl multiple servos from 1 channel with a Y harness, typically used for V-tails, flaperons, etc.Do the amount of channels on a r/c radio relate to how many servos it can control??
