Maybe exhaust nozzles are needed to concentrate / direct the motor thrust and keep it on center. There also is the possibility of increasing the motor thrust by accelerating the flow rate.

I spent alot of time working on it today...got the timer for the 2nd stage working properly, now I can time the 2nd stage in relation to the burn time on the 1st stage....put some small wings on the body too....can't get more engines till teus so testing won't be till mid week...starting off with 2 Ds to get it running straight again and test the timer...then work my way back up to E and F engines and hopefully get that 100mph goal....it's gonna be harder than I thought
