| emaxx tranny/ nitro power!?
do any of you guys think the emaxx can handle nitro power! im building something! and i want to be able to shift it from 1 st to second! and reverse is not a problem! And no its not a crawler! but i might do a brushless on it for simplicity thanks for the help! |

why dont you just use a T-maxx one? It has 2 speeds and can handle nitro

I would have to say that an eMaxx tranny can not hold up to nitro. When people use very strong brushless motors, like ones that are as powerful as nitro engines, they usually use a tmaxx tranny instead of an emaxx. | ||

E-maxx tranny does not have a brake disc setup,motors are the brakes.T-maxx tranny has disc brake setup already on the tranny. |

My Tranny isn't really a E-maxx tranny anymore, but even when I ran stock output gears, The force needed to strip the gears was more then a Nitro can produce. You can quote me on it and I will prove it if you don't believe me. A Nitro Clutch can not transmit enough torque to do any damage. Unless your full throttle off a sweet jump and land bad. The main problem would be heat and friction. I started crawling with a T maxx, I know you say its not going to be a crawler but think about it. A Nitro has to have over 10,000R's to start making power. Much of that power from the engine is wasted in the clutch by means of heat energy. An Electric motor makes close to full torque at any RPM. Two electric motors produce WAY more startup torque then a nitro. So it only makes sense that the E tranny is far more stout. With a nitro motor on an E, or even a fast brushless setup, you will more then likely heat the gears because of the speeds involved causing a failure of the plastic gears. RC4WD aluminum gears and lube would solve this but you still have the problem of shifting. Steel Idler gears are mandatory even for a stock E maxx. What I mean is the E is stronger then the T but the T is designed for nitro. If you put a nitro infront of an E your asking for trouble. The E is very stout but not designed to operate at those speeds. The ONLY reason people use a t maxx tranny is the fact that is it low geared. Atleast thats the only reason I can see. IMO they are JUNK. I run a 2.5HP brushless outrunner at 120 to 1 through my E-maxx Patlas tranny on 13.2v A123 cells. I can't see it ever failing. But thats slow. My Scorpion 3032 would scramble a T tranny in a matter of seconds. Yeah I built my own output gear from scratch but RC4WD has them too. Infact, if you wanted to use the first gear second gear then you would need the RC4WD gears to allow for the both gears. Plastic would NEVER tolerate the shock loads. *Its not geared low enough. It will be a DOG off the line. *Shifting will be an act of luck and a POWERFUL servo as the nitro's clutch will have drag and not allow it to shift smooth. *When/if it does shift, the shock load will likely destroy it. If you used it as a manual range select, you would be ok maybe, but if its fast your after, get a nitro tranny. To hook a servo to the shift and try for shift on the fly, I don't think its very possible as a good candidate. Use a Nitro tranny for a nitro motor, they are designed for it. You are going to have more trouble then it is worth trying to put a nitro on a E Maxx tranny. Last edited by WheelChair; 10-08-2007 at 02:41 PM. | |

I will never understand. Why people persist to. Put thoughts and opinions. On a forum like this. What I mean is. To break thoughts up into. Different lines so reading it. Becomes an exercise in retarded Japanese poetry. I believe that it should go. 5, 7, 5, for correct Haiku. Come on guys, I think that it should be pretty easy to get a coherent thought out of your brain, through you fingers, and on to a forum without making every person that clicks on said thread bleed from the eyes. I was tought that writing should have the same "feel" as spoken conversation. Do you puke out one line statements while talking to your family or friends? I hope not. If you think the way you post I feel sorry for you. One line of code generated and then executed at a time would make for a simple existence. |

I had a bone stock tmaxx tranny hold up to twin .46 4stroke engines and never have a problem..... the big drawback to the E tranny is the fact that the gears stack up leaves it a little prone to stripping a little easier.

i guess i can let the cat out of the bag! im building a replica monster truck! Its going to be sweet! And i love how the emaxx can shift on the fly but thanks wc for your imput it helped and made me decide that stuffing a brushless motor into a parma or some other model motor will work! im going to build it with txt axles 4 link and an emaxx tranny, it will look like the monster truck modern/iron outlaw! and it will run a full custom cage built by me!!! thanks for the help guys! |
