Default Evader RTR - How best to slow it down?

This may sound silly. I need to replace my wife's old old old nikko buggy. I think top speed on this thing was maybe 5 mph, but it was pretty reliable and very difficult to break at that speed. I'm eyeing the Evader RTR, but that's wayyy too fast. I would like to gear it down and install a slower 27 turn motor, but I can't find any info on which spur/pinion gear combos will fit or what RPM the motors will run. Any hints out there?

PS: I need to get all this for Christmas.

thanks much.

Ok, A 27t stock motor is going to be FASTER than the photon speed motor. Yes, the Photon technically has fewer windings, but the gauge and quality of the wire is what makes the most difference. My kids both have Evader Pro's, with Reedy MVP stock motors ( 27t), and both clock in at about 24mph. ( the Photon tops out at 20! )

Slowing down the truck is not as easy as putting in a smaller gear. I understand your concern, but that's the wrong approach. By undergearing a motor ( specifically to slow it down ), you will in turn damage the motor by overheating it. It does so, because the motor is ofrced to operate at it's maximum RPM , all the time. Not good for the motor.

If I can interject, the stock Evader ST ( Plastic ) is brittle. I bought the stock EP St for my son last June. For the 7 weeks we owned it, it was waiting for parts 5 out of the 7 weeks.

If speed is a concern, Please consider one of the Tamyia RTR models. They are a step up from the Nikko's that you are used to, but very durable. If you truly want the Evader, I would recommend the 'Pro' version, over the plastic version. The Graphite is actually stronger than the plastic used on the stock truck.

My kids are 5 and 7 respectively. They both have Evader Pro's, and have learned to drive them very well. Don't worry about the top speed being too fast. My son got the hang of it at age 4. Just go to an empty parkinglot to practice. That way, they can go fast, and learn how to judge the truck, without hitting anything.

I read your gearing article, so I got the overheating issue down pat. I'm not stuck on the Evader. I missed the difference that the Pro has stronger graphite parts, but I do like the improved ESC features that protect the drive train. I liked the idea of "free parts" but concerned about waiting on them. I'll check out the Tamyia. Thanks!

The solution might be to glue some stiff foam under the transmitter trigger to reduce it's throw.

With the 2pl radio, that comes with the Pro RTR, you can dial out that throw electronically. By retadring the End Point Adjustment, you essentially limit the trigger travel, and acheive what you're looking for.

If you don't mind me asking, why the concern over the truck being too fast? I really don't hear that one very often...[sm=spinnyeyes.gif]

I LOVE my re-release Tamyia Hornet. The RTR version comes with a 23 turn motor, so it is slower (around 15mph). The Gravel Hound, Rising Star, etc are all excellent entry level 4wd buggies. Each is sub 20mph in top speed, and made from ABS plastic, so they're plenty durable.

Hahaha... We got these Nikkos at sears clearance at least 15 years ago. They were pretty slow. She just likes to putt around with them. The E-Maxx we had was way too fast for her. She kept crashing it into trees, so it made her nervous. Plus, she's afraid she will run over her Shih-Tzu if she looses it. She LIKES the slow ones! GIMME A BREAK! LOL!!! (Just messing with you guys.) I orderd a QD buggy an an extra battery. The seem pretty tame. They're cheap enough, if she wants an upgrade (better car), we can work on that.

thanks for the help, guys.

lol cav that is hilarious...

Anyway I have never heard of wanting a slower car.... I would look at a traxxas stinger motor it is really really slow but lasts a long time. Depending on what you put it in, you should get around 20-18 mph.

An old Lemans 05 would effectively cut the top speed in half and last till hell thaws out after the big freeze... However, the best apporach is with a radio capable of limiting the end point throw of the trigger, as Skrappy suggested.

Here's an idea bgi, if you are into batteries then use an old stick pack with 1 cell removed for 5 cells. It will slow the top speed and also will make the truck a bit more lazy and easier to control. It will not have the neck-snappy resonse of a geared down vehicle.

Hey, u-dud, that's a good idea. Too bad I gave away most of my crap-o-la Shark packs. I'll remember that if I get a 6-cell buggy. The Tamyia uses the silly 8-cell AA packs.

I miss my E-Maxx. It was good fun. I may pick one up off a friend that's out of the hobby.

She has a toy to play with when I'm flying my planes...

I was going to say: those images are "avitars" go to the user control panel & upload yours!

Then I checked. I have no idea... They changed it.

Had a thought on your motor needs.. Why not got a 55 turn lathe motor? Monster torque but slow as Christmas compared to a 27t...

I agree with the earlier comment that a 5 cell pack is the best way to acheive your ends. Gearing will only slow it so much, even a 55t motor will have loads of torque and make it really snapping in handling.

Get a Rustler. They're slow out of the box.

i let my girlfriend drive my hummer a crapload of times, it had a mvp 27t stocker freshly cut so it probly did around 25mph, for a tramiya hummer it was flying and hard to control, she tore off a suspension arm twice and broke the grill piece out of the hard body, she also stripped one of my tie rods,

it sorta made me sick to watch her do this but whatever, its a toy

My son (6) has had a Stampede for a couple of years. He runs a 27T Monster Pro now, but we started out with the stock motor and a zip tie. Yes, a zip tie. I put it around the transmitter grip. It stopped the trigger from going all the way to full. No worries about gearing or anything special. When he was ready to go faster, I cut the zip. Easy.

I was thinking of something simple like this to limit the trigger. Thanks.

A zip-tie on the transmitter to limit the throttle travel?? The 5 cent solution, for the 50 dollar problem!

More like 0.1 cent. ;-) Much simpler than re-programming the ESC when I want to drive it!

That is a really smart idea! I spent hours trying to figure out how to limit the throttle for other ppl and that is all it would have taken....................................... IT KILLS ME!
