Model Forum / Radio Controlled / Land Models / February 2005stinger motor replacement
The Stinger 20 turn stock motor on my Stampede gave up the ghost. I'd like to replace it with a faster motor (of course). I did a google search here and one person found that the Trinity Speed Gem 19T 2 was faster and lasted longer on a charge than the stock Stinger. Any input on this replacement motor? Will it burn up my speed controller? Gears? Thanks, Dan Cutter The motor you mentioned should work fine. Even a 27 turn Stock racing motor (if worth a crap and set up right) will be noticably faster then the Stinger 20, and give longer run time then the 19. A nicely tuned 19 turn will be worlds faster then the Stinger 20. I have a 19t in my Losi 4wd buggy, putting that motor in the Stampede would be scary. I might have to try it :) The Stinger 20 is a real dud of a motor. Sure it's a 20 turn mod, but it is designed to be cheap and last a while, not to be fast. I have pulled Stingers from a 4-TEC, a Rustler and a Stampede and replaced them with Stock motors and saw an improvement in each one. Gears will depend on a lot of things. What surface you run on, do you run full speed all the time or part throttle, want more top end or torque? I would start at stock gearing and see how it works then adjust from there. Just watch your motor does not overheat. > The Stinger 20 turn stock motor on my Stampede gave up the ghost. I'd > like to replace it with a faster motor (of course).

However, I called two places to get the Trinity Speed Gem2 19T double wound and they said there is only a single wound Speed Gem 19T. I don't even know what that means, could you iluminate for me? And can I go ahead and use the single wound motor? Your reply has got me excited to put a 19t into the Stampede! BTW, I have an Emaxx too which is tons of fun, but the Stampede rules the skate park where it jumps way better and doesn't break either. It'll be fun to see the stampede after upgrading the motor.

Dan Cutter The single turn motor will work the same as the double. The current draw and top speed will be about the same, but it should have a bit more torque, if I remember correctly. Justin I don't have anything to add to what was said below on the motor. I do want to add that I have taken my nephew to the skate park with his Stampede and it was amazing! He runs a 27 turn "cheater stock" in his and he gets killer air. When your talking tough, your talking Traxxas! > > Thank you for you reply.

The Stinger is great for its intended audience: * little Johnny with his first RTR doesn't have to do comm/brush maintenance * sealed endbell means Johnny can't mess up timing, brushes, etc, resulting in endless toll-free support calls to the manufacturer. * decent battery life * 0-degree timing, which keeps Johnny from smoking his ESC in reverse (ie, effectively retarded timing). * probably very cheap to manufacture, as you point out. * 0-degree timing also allows the motor to be wired backwards and used in applications like the counter-rotating prop Villain IV boat. etc. It's a dud for experienced modelers and people who know something about decent performance motors.

It's *one* of the reasons to go brushless. THe airplane guys are way ahead of us on brushless adoption.

Out in the cool breeze, not much heating problems . Up in the air so not much dust . They spend much less time at small "thottle openings" so cogging is not really an issue. . Cogging is probably not very noticeable with the slippery drive systems (ie propellers). MIKE <SNIP> > It's *one* of the reasons to go brushless.

Out in the cool breeze, not much heating problems That's not a new problem with brushed or nitro. We'll adapt. We always have. >>. Up in the air so not much dust Again, you imply that dust isn't already a problem. Brushless motors have less moving/sliding parts, so they'll handle dust better than brushed. >>. They spend much less time at small "thottle openings" so cogging is not >>really an issue. You're absolutely correct on this one. See next. >>. Cogging is probably not very noticeable with the slippery drive systems >>(ie propellers). Ummm. Don't we already use slippery drive systems? Beefing up the slipper clutch is a small price to pay for efficient power. I love brushless. How about all the glitching i read about like from the Novak SS5800 setup? Who wants to spend $200+ and deal with that? > How about all the glitching i read about like from the Novak SS5800 > setup? Who wants to spend $200+ and deal with that? Just got my super sport installed. I can positively verify there is at least one SS5800 that does not glitch. BFG *big freeking grin* Justin Whats your setup? Battery?

Remember to drop some teeth on the pinion and check the ESC for excess heat after you swap motors. If you're running a mechanical speed controller, go as low as you dare and watch for melting wires. :-) Signaturehttp://cbsrmt.mousetrap.net/RMTdb/ CBS Radio Mystery Theater database CBSRMT uploads each day in <news:alt.binaries.sounds.radio.cbsrmt> http://greyhound.mousetrap.net/altus/ our ex-racer greyhound http://www.mousetrap.net/~mouse/cs.html How to get good phone support I am dating myself..but I have a traxxas hawk 2. It has the XL1 speed control which I believe is the same as the Pede. I use to run a 17 turn motor with no problem. I believe the pede is a lot lighter than the Hawk so should be really fast!
