I've been toying with the idea of doing a 3-way inline cluster, and just for added giggles canting the two outer motors to provide the most appealing smoke trails. The outboards would be more for show than anything else, so they'd be smaller than the primary in the center. Something like this:
Can anyone provide some guidance as to the advisability of doing this, particularly withe regard to safety if all three motors doing light?
The biggest risk would seem to be if the center and only one of the outboards doesn't light. But with the central motor being quite a bit more thrusty than the outboard, I don't know how much effect the outboard motor would have on the flight. Also, due to its canting, the outboard is pointed a bit more directly towards the CG (but not *exactly* towards it, probably), so it should apply less torque to the model in flight.
Is there an analytical way to assess this, or rules of thumb, or is it just gut instinct? Is this just a bad idea?
