    Mod 1.5 gearing help please

    Hi guys. Iím a little new to the gearing thing and itís confusing me. Maybe you awesome rcíers can help me. My current set up is a max 5 esc, leopard 5892 1000kv motor running a 35t pinion and 33t spur all that was available with the corona going on. The motor and esc temps are good no overheating. But Iím not happy with the speed or power. Can someone explain the gearing calculations or explain to me which one I need to go up or down on and what it will affect. Reading it back out loud sounds stupid but I swear Iím not Iím stuck. Please help. Or point me to the right thread. I canít find anything on the treads that helps me. Tia

    Where is your setup from?
    The closer to 1:1 gearing (the pinion and spur are the same sizes) means that you have more torque. The higher kv is more speed but higher heat vice versa

    I really hope you arenít running a bigger pinion than spur.... the pinion goes on the motor shaft.

    If that gearjng you said is true you have most likely overgeared the motor and will need to gear down.

    And what exactly arenít you happy with?
    Too fast? not fast Enough? Too much backflip wheelies?

    Pinion gear is like the front gearset on your bicycle. Spur is like the rear. Switch gears and how easy/hard is it? What gives you low-end power and what gives you top speed?

    So I need close to 1:1 ratio or for more torque and low end I need bigger spur than pinion?

    From here US.
    Yes I’m running a 35p 33s. Corona virus can’t find anything in stock or that doesn’t take 3 months to get to me in USA bc of slow shipping
    I have a 25t pinion that I had on it with the 33 spur and motor was overheating

    It’s too slow and doesn’t have the torque I want to pull wheelies on demand at any speed or throttle position and have good top speed.
    I would like to get this resolved so I can work on getting it set up more for 6’s for my son

    Get a belt drive to try, itís what I have and i like it. Although [mention]Gripdog7205 [/mention] didnít have such as good luck he didnít get the ones from him with the machined shaft for no slipping

    I’ve thought about that I read you tread on it and saw you set up and I love it ��. And you give great advice. I’ve seen you and gripdog post on multiple other treads and you guys are very knowledgeable and Friendly

    Thanks. Hereís my belt drive. I just got 15/30 gears. I had 25/30 and am planing on getting a 25t spur for other combos

    There than perhaps better quality gears. What does the 1.5mod achieve?

    Better quality than who?
    1.5 gears are stronger and less likely to break teeth.
    The wfo gears have a you break it you get it replaced warranty

    Did you pay to have your spur shaft 90 degree machined

    Acidic01 I’m sure there are some good quality gears out there. Better than wfo? I’d have to see them to pass my own judgement. I have the said gears and I can attest that they are top notch in quality and durability and I like the “if you break it we will replace it policy on them. “

    So in a sense if have a smaller pinion Than spur I’ll have more top in and if I have a larger pinion and a smaller spur I’ll have more low end correct?

    You really should never have a bigger pinion than spur as it puts ton of stress on the motor. The same pinion to spur is the most you should do.

    I guess what I was really trying to say is why would I go to 1.5mod over stock? Do see that one needs a after market motor with a 8mm shaft for pinion.

    Did I miss something?

    As you go bigger on the pinion and smaller the spur the less torque you will have. To gain power and torque you would go to a lower pinion and/or a higher spur.

    I like the WFO concept, by it avoid a lot of friction in gears, is the best thing of the kit, and the smooth sound I hear in videos I see in the web.

    So it’s in reverse ? More torque low end I need bigger pinion smaller spur? I’m confused now for sure. Lol

    Stronger, wider gears than mod 1. Ie: more contact surface and better gear mesh. Less wear or chance of breakage

    Small pinion larger spur more torque and less speed. Go up on tooth size on pinion, and you will get more top end. Just keep a eye on motor temp and esc.

    Smaller pinion, Bigger spur = more torque
    Bigger pinion, Smaller spur = less torque

    No. I made a flat spot myself, with a dermal. and it never thought about slipping. Took maybe 5 minutes. Keep in mind Iím not on the, knock your boy bandwagon, Iím just stating facts. Iím sure whatever issues folks had on here with him are probably due to growing pains or new business startup.

    I tried that before. I had a 25t pinion and a 33t spur and the motor was way to hot after about 10-15 minutes of medium no bashing run time

    Gearing up (raising the pinion) will just make the motor hotter

    I thought so to but like I said earlier I’m currently running a 35p 33s and can bash and play hard 25-30 minutes and motor not over 105 degrees

    Mate, I made a search in the web for hobby shops in your country, I understand that is hard to find online sellers offers shipping to your country.
