Looking at this makes me think you should probably pack a fire extinguisher just in case...

It happened to the ProMod car when it was a nitro .18 too!...
The O-ring tires were super glued to the plastic wheel as well!...still blew!

A thought occurred to me. for the Dual setup you might want to do an over under setup instead of side by side that way if the timing is off it won't steer the car to the side.

Best I can tell the timing of the engined is spot on...plus the consistency of Estes products!..made two runs...both ran exactly 72 mph...we will know for sure tho in the morning...also, I plan on putting the single mount on top of the duals..getting a much more streamline body.....going to go 3 engines eventually...130mph in 2.4 seconds....want to be the fastest in the world
at 132ft...even tho they wont let me compete with it
