A few weeks ago i was reading on here about using a helicoptor gyro to aid in steering a rc truck. I ordered the ESKY something or other gyro for $14 off e-bay. I got it yesterday and quickly mounted it on my Rustler VXL. ***!

I just put it on with double side tape over the steering servo did adjust anything. At first I noticed the slow speed turnig radius was a little wider but that was ok. The I started doing some high speed runs, this is a 3s maxamp 5000 battery with 23/76 gearing using anaconda tires with the traxxas wheelie bar all the way down. At first the car was twicht at high speeds but after the second or third run it went away. Then I tired doing a high speed turn around the corner (all this is on asphalt) and the car got crazy sideways after a few runs the tires were howling so much that a buch of neighbors came out. I've never pushed this car so hard, it was absolulty crazy the control and full power slides on the street this thing was doing. But the fun was short live about 15 minutes into terrorizing my neighbors the car came to a stopwith a high pitches whine like a stripped gear.

Upon closer inspection I have broken one of my output yokes, all of u joint holes were oval and about to bust and I cracked both of my back rims just from power sliding so hard.

I'm going to fix it and maybe experiment with a Sidewinder esc to take advantage of the punch control. Is there any stronger half shafts and yokes? I don't think i could stop doing this.

That gyro must have been crazy heavy [&:] What would it do to help the performance?

Spetz

So, besides wear and tear, did the gyro work well?

Sounds like you had a blast right before things broke!
I am now tempted to buy one. Do you recommend it?

My Feedback: (1)

i think gyro's are best used in drifting.......because they want to go sideways

robg68

I definitly recommend it but if you are using 3s or more lipos take it easy on the street. It's just the full power slides on the street give too much traction for the wheels and drivetran. I've had this car for over a year and I've never broken a wheel . I also use 60K diff fluid so my rear wheel differentual is pretty limited. Even so this is by far the best $14 I ever spent on my car.

Spetz

That's good to hear!
So the gyro really helps the car keep a "straight" line and not spin out all the time?

Can you post the gyro model number??

robg68

the model is Esky EK2-0704, make sure you don't get the Esky EK2-0704B.

It keeps the car straignt by making a bunch of fast minute corrections that you never could. Example I could floor the car to about 40 or 50 mph, nail the brakes while turning the wheel slightly to get it sliding around the corner, half way though get I could get on the gas and have it power out of the turn. Before I would get it up to 20 mph, get on the breaks hard and just spin out.

here is a thread about running the gyro...lots of info and testing

I will difinitely look into it
The idea of some sort of stability control in an RC car intrigues me!

Foxy

There's no doubt that a gyro can make the most cack-handed RCer look like a drift king, and can also help dramatically with controlling overpowered cars. Just bear in mind they are totally illegal in racing.

robg68

Redfisher, that is the thread I was reading that gave me the idea. As for the racing I just bash so that's not a problem.

redfisher1974

Im going to order one.....looks like fun and you can just unplug it whan its not needed.

Spetz

What happens when you get lift off oversteer? Does it correct it?
Or does it only work on power oversteer?

Foxy

It corrects any kind of error or situation within the limits of the model, cos it is based on the attitude of the car (the g-forces felt by the gyro), not the control inputs.

robg68

It correct all over steer, the only situaltion where it doesn't work too well is if the front tires are in the air but as soon as they touch down they are pointed in the right direction so those traction rolls (flips) coming off of a slidig wheelie with the wheels turned are non-exsistent.

Hate to revive this but I just got the 0704B and it works great...when using a plane remote. Hooking it into my 3 channel TQ it doesn't work. Just slowly blinks. I just now saw someone said to get the 0704 and not the 0704B. Is that because the B doesn't work with car remotes and the 0704 does? Or is there a way to get this one working?
