nose diving!!
 
When ever i hit a jump at speed thr pro just nose dives and i cant figure why any help is welcome.

Keep the power on when the car's in the air and the front should stay up - Have you got any extra weights in the front at all? Any Drag brake set-up on the speedo??

Any of those will cause the nose to dive

Paulmay79 28-09-2009 02:44 PM

Ive got no weight on the front and im not sure about drag brake.

Paulmay79 28-09-2009 02:48 PM

Just checked the drag was set to 10% ive now set it to 0% so ill have to test it later. Cheers Nick

have you increased the rear anti-squat, 2mm of spacers under the front mount for the rear suspension. (you will have to dremel the chassis to allow for the higher position of the bracket)

put loads of weights on the servo and some at the back of the gearbox and some on the chassis. it need to weight 15.50grams with the battery . buy some core rc weight £3.00 for a full pack should do it. or add some lead

15.5g, are you sure?! lol Think 2wd is 1480 ish off the top of my head

And for weight, just go to a local kwikfit and ask the guys for a couple of strips of wheel balance weights. They hand them out free usually!

i got told it was 15.50 but not 100% sure :)

DCM 28-09-2009 03:29 PM

it nose dives, as the rear is kicking up, as it crests the jump, the rear anti-squat will help with that.

By this do you mean raising the inner brace on the t piece? If so im with you.

over all it is about 1650 with battery.

sounds about right Paul, most people run them a fair bit overweight

Paulmay79 28-09-2009 04:08 PM

I find it helps traction and control. Its just the diving thing but ive still got to test it now ive turned off the drag.

sparrow.2 28-09-2009 04:09 PM

Could be your back end is too soft too, causing the back end to slap the face of the jump which kicks the back end up.

Increasing the antisquat might make it crap on the bumpy stuff but make the back end rotate nicer into corners...

Really looking forward to my first race with the rat soon. Will hopefully make a change from running a B4 for a while. The endurance race with the truck really showed the potential of the Ansmann stuff :)

Paulmay79 28-09-2009 04:11 PM

Did you get your t??

sparrow.2 28-09-2009 04:15 PM

Yes I did! Sorry meant to let you know. Fantastic piece of kit!

Sadly weren't allowed to run it for the endurance race but it went on completely straightforward and should help running mod over the winter.

Paulmay79 28-09-2009 04:17 PM

Good im glad your pleased.
