Spark on launch of jump
My 8ight-B (1.0) has a spark when headed up the jump. I assume there's some chassis flex at that point, but I don't know what is sparking as a result of the flex. It seems like it's coming from the rear or mid-rear section of the car. Performance is normal, no problems.
It's not the spark-of-clutchbell-death I've had when casing a jump .
Any ideas?

Could be rocks on the face of the jump. Are you using titanium screws in the bottom of the chassis anywhere? Titanium can spark with moving static electricity. It might be the chassis flexing. Does the clutch bell and spur gear look ok?

If you notice when you marshal at Indy, about 30% of the time during a race various cars are doing that on the big triple. I was standing at the corner before the runup for that, so I had a good view of it for the whole main... Nothing to be concerned with if your clutch mesh is good... now, sparks like that CAN be when you break a clutchbell or spur gear (it looks the same... worried the heck out of me the first few times mine did it at the Texas State Series race... but it was fine.)

Thanks for the replies. I'm relieved.
Yeah, it's at Indy. I notice it at the triple near the stand (the back triple is too far away, lol).
As far as the clutchbell spark goes, I'm very familiar with that... too familiar with it. lol. The track change introduced me to the wonders of shearing clutchbell teeth, particularly when casing the triple. I went through a clutchbell every week at first. In one race, I stripped all but two teeth from the 13 tooth bell on my truggy. . I've got it under control now, though. I land the backside more consistently, I'm off-power, and I put the Robinson bells in both truggy and buggy.

Mark. Ive noticed that also. Sometimes when people take off there is a little spark. I think it is just tiny rocks in the soil. Nothing to worry about. Even tho at INDY it does not appear that there are rocks. Take a look at under your chassis. Some of those scratches are pretty deep.
Yesterday was a blast tho. Motor was running great. Car was performing pretty good until the track dried out. I put the Smart diff in last night and can t wait to try it next thursday?

Get some of the Skid Plates for your Losi. They are amazing. They make a molded bumper for the front skid plate and rear skid plates for both Losi 1.0/2.0 chassis. It will also greatly improve the life of the chassis. DE Racing makes them for I think every model buggy out there.
Its about 8 bucks for 3 rear plates and 8 for 1 front bumper skid. They are rock solid and I have tested that more then enough .. They also just bolt right in with original hardware.
And its free shipping I believe. Look them up.
