Re: Old School Rocket Car Build
I thought they were using rocket motors without the parachute ejection charge. Just all 'go' power in the motor.

Re: Old School Rocket Car Build
The car went 85mph in 1.7 sec in that video with a small 13lb thrust composite rocket engine....2 days prior I ran a 23lb engine for 1.4 seconds....thing was ballistic but I didn't get a start on my GNSS some didn't get a read....got lots of new engines I will be testing in the near future...stay tuned!

I think you sent me a dupe that I didn't post and that was it. I'll check. This was today.

Re: Old School Rocket Car Build
So the end of run tumbling... it's like you need a ramp at the end and some James Bond style deployable wings. Just sayin'.

Re: Old School Rocket Car Build
I wonder if it's the duty cycle or refresh rate of the testers ? Maybe they just don't test frequently enough for that kind of acceleration?
If a jobs not worth doing then its certainly not worth doing well.

Re: Old School Rocket Car Build
The "braking zone" looks pretty brutal. Is the chassis holding up well?
