Smoke system for gun barrels
May 26, 2025
Since I've been making these systems for others' Cobras (Roban, Vario, LM, Alterbaum), it's time to put one in my own. This bird is already jam packed with electronics (animatronic cockpit and sound system), locating space for the smoke tank and pump was challenging in a narrow fuselage. Because of all the added contraptions in the nose, this model has the unusual problem of being too nose heavy. In order to achieve a better cg, the lipos have to be located rearward, standing vertically in a side saddle configuration. 2x 3d printed L brackets attached to the side frames allow the lipos to be strapped tight using hook n loop straps. The nose area is now free to house an rx battery and miles of cables and electronics.

Hi Patrick, we will up the size limit on videos. As for posting, we have an “Other Scale” category under which you can choose Len Mount (but not the specific model).
Hey Patrick, we bumped the upload limit and it appears that you've taken full advantage! This video looks great! Of course, the subject matter helps. ; )
I understand native video streaming adds to the server expense. But I think it's a crucial feature to reduce usability friction. Hope you negotiated a good deal with a CDN such as Akamai:) Alternatively, you could allow embedding FB video, where most scale videos are already hosted.
Often overlooked but always appreciated!!
That looks excellent Patrick
You do great work Patrick !!
very Realistic wow
Very nice machine !
Motion including arms is awesome, I find it realistic. Must be very visible in flight. Well done!
It was a static display project, I've never flown it with the outboard passenger. His seat- the ammo bay door is supported by 2 tension cables, therefore not a rigid platform. I'm afraid he'll be bouncing up and down during flight, too risky.
How heavy is this bird now?
29.5 lb flight weight.
Nice build, specially the CG optimized Lipo position. Impressive features at the front gun.
