Hi,



JL tjets are not that bad. <img src='http://www.h0slot.de/public/style_emoticons/<#EMO_DIR#>/wink.png' class='bbc_emoticon' alt='' />



In stock version, tye 've got stronger motor magnets and armature than original aurora cars, and once tuned (polished gears, finding hard points in gear mesh, balanced shoes and brushes, long guide pin, wide silicon tires) the car runs great. It 's why (I think) it's a chassis often used in "rookie" racing classes in USA. Cheap and eficient one tuned. You don't have to buy a lot of aftermarket parts to make it runs.



the only issue, is that JL cars NEED to be tuned, and doesn't run correctly out of box. And the lenght dimension of the chassis is slightly different than the original aurora chassis (causing some problems with mounting posts and wheelbase, but nothing impossible to fix).



For the brasspan, the only problem is that you loose some break effect. The weight cause inertia. But the car handles better in tight curves. I made some quick timing tests this days :



ferrari 250gto without brasspan : 7.9s record, with stable 8-8.2s

with brass pan : 7.473s record, and stable runs on 7.6-7.7 seconds



So the brasspan brings you a improvement, because of the very low gravity center. And if your track has the brake wired, it should be even better (mine track has no brake).



You can see my ferrari 250gto, with brasspan, under 14volt :

It's fast enough for me <img src='http://www.h0slot.de/public/style_emoticons/<#EMO_DIR#>/laugh.png' class='bbc_emoticon' alt=':lol:' />



For the alfa romeo, I choose this racing color scheme :
