    ok I have a Atomic force 17 turn motor and I did not put the caps on it and it runs just fine. My question is do I need them on? I do not get any interferince at all.


    For timing it says the motor has adjustable timing, my questions are is it worht it? How do you do it? If any 1 has a link they could post on how to do it that would be great!

    Did it come with 2or3 capaciters? either way just tigh them into each other and solder to motor tabs. I would use them to help with radio interference. Timing can be a little tricky that 17t is probably set at about 15 and 20 degrees. I would never advance past 20d ,I found on my Gem motors 17t that about 14d works good batterie last alittle longer and motor last longer . What are you running it in? RED

    I am running it in a traxxas 4tec, would the caps really make a differnece I have had no problems at all! How do you set the timing? How do I know where it is at?

    I would use the caps do what you want thats up to you , Now timing you have 2 screws at the end bell loosen them, you dont need to remove them . On most motors each mark is about 6degrees timing so count were you are at. use the marker on the end bell and count from zero mark to were the mark on the can is .
    That well tell you were your timing is set as I said before I would gess at 15 to 20 deg.

    I meant not to excide 30degrees that'll totally fry that motor.

    After you get your 17t worked out drop a Speed Gem 7t and drop your gearing that thing well fly. THat 17t should get you around the track purdy darn fast to with the right gearing. Make sure your gearing is correct for that motor or youll smoke it. RED

    well for the 17 turn I was running I think a 27 tooth pinon and a 66 tooth spur, my LHS has a 51 tooth on its way

    for speed gems the lowest turn I can find is 9t

    That 27/66 is more for a stock motor like a 27turn with a fixed 24deg. timing. Try looking on the Tower hobbie site for the other Speed
    Gem motors , there cheap about 31. bux each .

    well the way I was told big pinon small spur equals speed!

    Brother the pinion that I suggested is big 27teeth big and the 66 spur well flat out fly thats why I said w/ a stocker motor 27t. And yes you are so right the bigger the pinion and the smaller the spur the fast you'll go but keep in mind that gearing is the real key to top speed the motor is what is gonna get you there faster, you cant over gear or under gear motors or youll fry them.

    Heres a little more help for gearing ,just keep in mind that a good starting point would be this always start with a pinion gear that is 2 teeth lower than your motor , for example you have a 17turn motor set at 16 deg. timing use a 15 tooth pinion gear, I'd even say change your spur to a 82 tooth and work down if you need to youll end up with a lot of punch and good top speed.

    good luck with it , if you give me your tranny ratio I can figure out your final drive ratio for you , RED

    I downloaded this gear program that tells you the speed for like different spur gears,pinons,tires,and motor RPM's, iv been messing around wiht it and all but I dont know how many RPM's my motor is. I checked on towerhobbies and the kyosho motor site but no luck. The motor is a Atomic 17 turn by Kyosho. Can you help me find out the rpm's?
