Mark Richards, some info which may help. I run my DB10 with 2s lipo saddle packs /13.5 motor with the batteries in line down the chassis, running in high grip track with full size spec tyres (BRS) it handled very nicely with a bit of under steer. I decided to run the saddle pack across the chassis as per the nimh cell position, it turned into a disaster I only had to show the car a corner and it was on its roof, tried stiffening the back/ front, different levels of additive, spring rates etc but could not cure the problem.

On checking the weight distribution of both layouts found with the stick pack configuration I had 70g more weight on the front of the car, reverted back to stick pack layout and car back to its best. Try some weight over the front of the car.HTH

blackbird, did you drive on a carpet track? Did you also try to put the saddlepacks completely at the back? could it be that you used full sized tires that made you traction roll?

Just curious.

Hi 2wd, had the saddle pack in the rear most position with the esc behind them also had 30g of ballast either side of the esc.I always run my tyres from full size as cannot bear to size them down

I am going to try the saddle pack again in the cross chassis position but adjust ballast to match the wheel loads I have with the lipos in stick pack configuration.

I drive indoors on a large carpet track

Why did you switch from the center location?Are you trying to move weight back?You might want to tidy up the wiring a bit.The motor wires look that they may cause a tweak issue.
What is your front track width?I moved mine out a ton and think it will allow my car to carry more corner speed without the fear of traction rolling.I'll be back out at Lou's to put the BMI up against all those CRC's.I could always use a teammate to help with R&D.

half too none.

1 cell lipo in the position of the old cells. not a great deal of weight too move around. cell is in an inline position until i can make a new 'top deck / battery bar' that will allow me to locate the cell sideways.

My feelings at the moment are there isnt enough weight in the right place to hold the car down. so when the mid corner loading occurs the car flips.

I've gone softer on the springs, which now gives me a better turn in without, oddly, making the car flip any more often.

Running tonight on different tyres. Carbon effect instead of BSR. Different track and carpet though to my other club.

Default getting better

Ended up running the BSR wheels again as my arbour for my tyre truer doesnt fit the carbon wheels. The offset seems to be wrong.

Changed mounting position of side plates to the rear hole. Car handling better, no grip role (different carpet to origional posting)

New and very weird effect. Front of the car seems to bounce when loaded... flex perhaps ?

With this post I want to thank WorldGT shop http://www.wgtshop.com/ for the very good and fast service they provide. The owner of WGT shop is very fast in replying to all questions i had about the DB10R. He even answers mail on saterday and sunday to help out with whatever problems there are. (personal experience as i bought and build the car last week or so). He also gave me hints for building the car and reamed the spindle blocks for me as customer service. Thanks .

This sunday will be the first test during our first indoor race. Haven't tried the car yet so will have a basic setup and start from there. Class is 13.5t 2s lipo with gt bodies.

does anyone have problems fitting a standard size servo in the DB10? I can't center the servo saver in the middle of teh chassis as the servo can't move any further to the left (looking from the front). The servosaver is roughly 3 mm off center.

As I understood it... the chassis is set (drilled) for a mini servo Futaba 9650 or one of similar size.

the futaba s9650 has 4.5 kg of torque and 0.11 sec at 6v. is that enough for a 1/10 pancar? Just curious. What servo are you all using?
