Hi guys
I run a B6 on a very flat and grippy astro surface with big jumps. My B6 is flying dramaticaly nose down. I am obliged to accelerate at maximum in the air to flatten the car. Sometimes it is not suficient and it lands verticaly ![]() Any idea to improve that ? My set-up: Little drag brake Front shocks: Red springs, 45 Losi oil, standart pistons Rear: Blue springs 37.5 Losi oil, standart pistons Ride high 18-19 mm Thank you |

I would say take the Drag brake off completely

plus it's an easy thing to try. No need to fart about with weights. When a 2wd car is in the air it doesn't take much braking to get the front end pointing downwards. |

Also consider your rear shock package. Sounds a little too stiff, not familiar with Losi oils, but 37.5wt on the rear sounds thick, combined with stiff spring (blue) could be kicking up the back end over the ramp pitching the nose down....
Ideally need to see the car in action to advise better, but that's a thought. Most b6s that I've seen jump well and a look nicely adjustable in the air. Last edited by charlesk; 16-04-2018 at 08:08 AM. |

What surface do you run to go with 37.5 rear oil, most run about 32.5 max

I run a very flat surface of concrete (old tennis terrain) covered with very high grip astro.
and we have big wooden double jumps (covered with astro also) At this rates Losi wt oils nearly equal to Asso. We run very low cars (18mm) |

As above, too much drag brake will dip the nose, I run about 8% on my 2WD. Other stuff such as angle of your shocks and anti squat plays into how your car jumps also.

Hi,
Sounds like the rear oil springs are too heavy. Looking at the conversion chart. Losi 37.5 oil to equivalent to AE 35. I'm running on indoor astro, astro is laid on concert floor, with wood jumps. Rear I'm running 30 ae oil (32.5 losi oil) 1.7 piston and 2.1lb spring. I have no problems with jumps, running 17mm ride height. (Track video: https://www.youtube.com/watch?v=EYkHF9op5A4) Let me know if you want full set-up sheet. MiCk B. :-)

Hi Allan and Mick
This is the track we have at the end of this page http://www.automodelisme.com/forum/i...Posts;start=60 Seems as flat as yours maybe with bigger jumps ? Mick: Yes if you can send your set-up please I can compare both and try your shock set-up ![]() |

Hi,
Thanks, track is indoor, so space at a premium, but doesn't get rained out. The blue astro on yours is nice. Set-up attached. Any questions, just ask. MiCk B. :-)
