Naw, just more POWER! It is straight and stable when moving fast. Lots of Power and nose weight solve 90 to 95% of your problems, just like cold, hard cash! Trust in thrust!I wonder if the problem is a lack of yaw stability. I know it messes with the crane aesthetic, but could you add a vertical stabilizer aft?
The flight ain't over till Madonna sings!Now that song is totally stuck in my head: "The truth is, I neeeeeever left you, all through my wild days, my mad existence, I kept my promise! You kept your distance....."

I think all that drag didn't help much too. Just needs more sustained power, stability was fine, just ran out of oomph. Quest has those E26 motors. 3 times for F78? Better power curve. Maybe 3 F39s if that doesn't work, get into the G power band! Taking out noseweight will move the CG back then it will really want to go horizontalYa, i was a little worried when i asked you how much nose weight you had to use for the cog and you said you put plastisen clay in the whole nose section. Way too much for that no doubt. you are probably correct in more power may make it more stable...
E12 0 with a pinch of BP on top!You could argue for same thrust, shorter Delay. Won’t be a high flight, but pop the chute just as it starts to go south on you. I don’t think cranes are known for being high altitude flyers anyway.
You can drag race a saucer!E12 0 with a pinch of BP on top!
Okay, now you are just teasing us. How was the REST of the flight?Woosher showing off the gams and doing the mating dance for all the lady cranes.

Yes, inquiring minds want to know. The still-photo looks terrific!Okay, now you are just teasing us. How was the REST of the flight?
Woosher flys fine on the E12 0 motors with a pinch of BP on top of the motors. Videos are on Facebook. Model rocket fanatics. This was Wooshers third flight.Okay, now you are just teasing us. How was the REST of the flight?
I have been following your OddRocs for a while but this is the first time I have paid attention to the motor choices.Woosher flys fine on the E12 0 motors with a pinch of BP on top of the motors. Videos are on Facebook. Model rocket fanatics. This was Wooshers third flight.
I just take the same amount of powder contained in a 24mm AT reload charge and divide it among the 3 E12 0. Works good as Woosher dosen't have a huge recovery volume. Woosher is a naughty bird and likes to zigzag if not under full thrust, the gams get in the way! So it's either clustering more powerful composites or just going with no delay on the BP E12. The E12 0s have worked so I'm sticking with them.I have been following your OddRocs for a while but this is the first time I have paid attention to the motor choices.
Choice of a zero delay suggests that you are confident of stability under thrust, but anticipate rapid if not immediate loss of stability during coast phase.
Is this the prototypical flight plan for your creations, which tend to be awesome AND high drag designs? I.e., “TRUST IN THRUST (but not in coast)” ?
is the pinch of BP because the “ejection” force from burnout from a (non-doctored) zero delay motor (no clay cap or “true” ejection charge) is potentially insufficient to deploy the nose and laundry?
