... I was wishing for a lunsford kit with the throttle/brake servo and steering servo ones also, you can save some fine weight with all those, it is 5 links for that alone. I think about an ounce (~28g) can be saved.

If you go to Jaf1977's pic, the spring will be located between the turnbuckle tool hub and the servo horn slider, so the slider will be working against 2 springs, one at each side, trim the slider about 3 or 4 mm on the side of the new spring to make space for it and the geometry stays the same and that's it.

I'll try to post a pick of mine. Ive never fried a servo in any car with this method. I had a Losi 1.0 with the tray fully screwed to the chassis and ran the same servo for 3 years with no failure. Its the servo I have in the dnx408 now.

The reason the servo burns is because of flex, chassis flex, when you are at full throttle and the car hits a big bump sometimes the engine wants to pull away from the servo, if the linkage has no give (e.g. spring) the servo will suffer the whole strain of this pull, which can be substantial on a 7 plus pound car doing 30 mph on the straight.

All I can say is that I have never gotten a servo failure with this method and I have been using it for 5 plus years on all my cars no matter what they are.

One thing to make sure is that the "throttle side" spring should be stronger than the "brake side" spring, so you keep the whole deal working properly (so it open/closes the throttle).

Try it!

Thanks for the info pic's would really help, I wander if vibration is also causing these problems. When the motor isn't running servo worked but as soon as I stated it up would not work and jump around a bit some times. I am thinking to put some orings or fuel tube between the radio tray and plate to raise it some and should dampen vibration and allow some movement if needed.

Guess time will tell, hope so...for all the truggys racers. Seems like truggy class is getting bigger every year, around these parts anyway. They are fun to watch..... something that big moving so fast and sticking like glue.

Last weekend i was lucky to get my 1st outing with my Durango, nothing really challenging just a hop skip and plane trip across to southern France to race at a small meeting, Montpellier GP 2011.

It was a great expereience to be there with, all the top drivers( |elliot, Reno, Jorn, and try to learn as much as i could on how the car differed from my old Mugen, from the moment it 1st left the pit lane i knew it was very different.

For those who have seen the pcitures or videos as normall the track was more difficult than it looks, not much grip.

That said the whole experience was very useful and by the end of the weekend and another 2 hour test on monday i am certain that the car will be awesome, The team drivers seem to be working hard to get the best understanding from all different track types, so i am sure we will get thier feedback on how to get the best from this awesome car.

Got the next 3 weekends booked racing and testing as long as the UK weather is kind.

Next big Road trip is i am coming to Cali in July and was wanting to bring the car out for some racing and testing, i am sure some of you can point me in the right direction on where to go.
