Loc Bullet - Cluster - Stuffer Tube

[RobP]

Hello to all,

I'm currently planing/building the Bullet from Loc Precision.
Instead of building the Bullet with a single motor mount I'll construct a Cluster motor mount for up to 9x Klima Motors.

What would be the better construction for a stuffer tube?

1. All of the 9 motor tube will be lenghten (see Picture 2)
or
2. The motor tubes will be shorter and an additional single tube after the motor mount will be the stuffer tube (pic 1)

Thanks!
Best regards
Robert

Option 2 ( Pic 1 ) should have a more favorable CG.

Hi to all,
if someone is interested how this story ends last year...here is late feedback

Regarding the motor tubes for ejection I only lenghten 4 of the 9 motor tubes. So max. 4 motors should have an ejection charge.

To make it short...the Bullet flys beautiful. 6x D9 motors are enough for a slow flight to 200m
2x Motors with ejection charge are enough , 4 pcs are not needed

Best regards
Robert
