Picco + Losi 8ight rocks.

[ame="http://www.youtube.com/watch?v=KrMO5reqTJQ"]YouTube - Losi 8ight 2.0 bashing.[/ame]

The Losi is defying being bashed until broken. It won't break. I hammer it, cane it, flip it, cartwheel it, bounce it off stuff, jam it's wheels with gravel, jams it's steering with gravel and all it does is idle impatiently while I clear them then go back out to look for more trouble to get into.

So the Picco is broken in enough to cane it Still haven't bothered to tune it. It's a 1/4 turn lean from factory HSN, LSN is factory, I tried another 1/8th lean, but it hit 115C so I richened it back.

The high idle and the fact it takes so long to settle back to a gurgling purrr does annoy me, it wont cool itself buzzing away, though usually as it cools a few throttle blips drop it back down to purr.

Idles at 80-85C currently hits 111C after a long flat out run down a field. Sounds and looks tuned to me

I put a whole 400ml fuel bottle through it today and the best damage I could do to it was to strip the servo horn adapter by lauching the buggy from full tilt, 50 yard run up, off a grass jump, tumbling, it rolled like a rag doll for like 30 yards and... stripped a nylon servo horn adapter..... its indestructible!

Any thoughts on curing the high idle when it's hot?

Take a look at this thread:

The first post goes over a general tune pretty good and explains a similar scenario to yours.

Good quality stuff makes a big difference huh? :yes:

Picco's in general like a small idle gap, set the gap at .5mm and then use my tuning guide for your performance tune, that idle issue should go away. Looks like all the hard work at first has payed off in the long run, glad to see your really getting to enjoy it now.

Absolutely. You were due for a good day Paul. I'm happy for ya brother.

Well, from that guide (Awesome, thanks) it sounded like I was sitting on the lean side of a perfect tune, so I richened it by an hour and once the engine was warmed up it dropped straight to low idle coming off the power. Still goes straight to whaling like a banshee when you give it the boot though

Except... handy enough when the tanks running low. So I get a low fuel warning when it starts to idle up.

Stripped a second servo adapter today, think it was the wrong side to begin with. So I've ordered a metal servo arm, hoping the servo saver will do it's job then.
