Oh the tribulations of silly oddrocs, forces you to think backwards, outside the box. Heck, just throw the box away.Lol, there was a word replacement in my previously reply which my immature sense of humor thought would be appreciated . Probably would only apply to flying REAL trees AFTER Christmas, which nobody should do anyway.
with all due respect to those who subscribe to the “In Thrust We Trust”, with the exception of tractor motors, since I started scratch building I have always been dubious about solving every problem with added nose weight and added thrust.
you add nose weight and definitely makes it more stable by pulling CG forward
but if the added nose weight precludes you from get a draggy OddRoc off the rod or rail with sufficient velocity, you have to add more motors in the tail, which brings the CG backward
so you add MORE nose weight……but then……
you can see how this may end up both literally and figuratively having your rocket design chasing its tail.
my go to solution for instability has usually been to increase the tail feathers AND the thrust. Agreed the added fin surface area does have a cost in both weight and drag, but particularly for rockets that start with a far forward CP, it seems more efficient than just throwing in more nose weight.
I would always tell our old RSO that power and nose weight solved 90% of my oddrocs problems and THAT ain't bad. He replied that the other 10% of the problems were far too serious and to go launch it in South Park.
Be kind to the crabby old dudes this Christmas, they are just trying to keep you safe and sound. SINGING: CAPITAL CITIES SAFE AND SOUND.
