Probs with Sidewinder
 

Hello, I'm a new RC fan.

I just bought the Kyosho Lazer RTR with Castle Creations Sidewinder with 5700kv engine. I think it gets overheated (i felt on the engine and esc and it was really Hot) I have the original pinion on the 5700 engine.. the car runs great, great acceleration och high topspeed, but after about 5minutes of pretty rough driving it just stops. Once i turn the esc off and then on again it works for a couple of more minutes. Could this pinion be the problems? That the engine runs with to high revs?

Has anyone had this problem? How did you solve it?:confused:

Is a coolingfan something to recommend? Or maybe a hole in the body for extra aircooling to the esc?

I apologize for my english..I'm from sweden..;)

thanks!

It's definitely a thermal shutdown. Yes, it could be the pinion. What gearing are you using? Some small vent holes can help. Buggies generally run a little hotter because there's no circulation. A fan helps a lot, but they are a pain and you shouldn't need one. Try adding some cooling holes and dropping the pinion one tooth.

Sounds like it might be getting a little hot. I would run a smaller pinion and or larger spur gear or a combination of both. Holes in the body above where the speedo is would help as well. Could also use a small fan on the speedo as another option. Another thing is a using a lower timing on the motor if you have it set high.

thanks for your help.

I will try a smaler pinion.. and perhaps make a little vent hole in the body.
How can I tell if the ESC or the engine is getting to hot?

I run the default settings. But I might have to try a lower timing as you sad.

Thanks again!

I'm using the original gearing in the RTR set... I have no idea what that is.

Normally a temp gun is the best way to check the temp.

u should probably be running a 17. i run a 17 with a mm5700 zx-5 sp. also make sure ur mesh is not 2 tight

I now have a 15t pinion and the engine set on the lowest timing. The engine is cool as ice even after hard racing.
But there is still probs. I now think its something with the transmitter. I lost "connection" with my car after about 35-40meters... I'm gonna try new chrystals today and if that dosent work I will by a new radio and trasmitter..:cry:

Well its cool that you have the speedo and motor temps down. Normally its simple stuff to fix the problem.

For the radio new crystals is a good thing to try and if that don't work try another receiver if you have one to test with.

To night I'm gonna try a different transmitter, radio and even a stock engine and esc.
So today I'm gonna find the problem.:nod:

make sure ur wires from ur esc to motor r as far away from receiver as u can get them, they will make ur radio glitch. i had to change to a 2.4 speky cuz of the same problem. i have also heard that the bullet connectors can also cause a problem, so u might want to short'n wires and get rid of them.

I went to a 2.4 spektrum setup with my MM and fixed my glitching problems.

me and brotheer law had to go to 2.4 to solve problem

Lots of things can cause glitching. If your batteries are not strong enough that can cause a problem, the connectors can be a problem unless your Sidewinder has the new Castle bullets which then the way they fit tight I then highly doubt that is you problem as they are excellent and fit alot better than the standard bullet connectors.

If you have bad crystals can cause a problem as well. Just too many things to think of right now but it is a few more ideas for you.

Yes, just for future reference remember that stock RTR gearing is normally going to be way to high for a faster, lower turn motor.

You might find yourself going to 2.4ghz like a lot of us have...it makes a lot of things easier and I've never had to worry about glitching since I made the leap.

If the Radio equipment is shot, consider a Spektrum DX2. Its budget friendly, comes with a nice receiver and servos, and Spektrum makes great stuff. Here is a link: http://www.horizonhobby.com/Products...rodID=SPM20200 It is on backorder though. Should be in soon.

In the case that you do need a new radio, it will be beneficial in the long run to get a DX2 or similar 2.4ghz radio now rather than later when you really need it.
