Has anyone been able to print a main gear for 550 or greater size heli that lasts more than 30 seconds?

if it doesn't fit, make it fit.

I cut them on a CNC... plastic printing hardly ever produces parts that are structurally better than one machined from solid stock and the surface finish is critical as is the plastic used. Granted this may not really be true for for most high end professional printers though.... but 3D printers of that quality are not affordable nor practical for hobbyists.

here is an example of two gears I cut using CNC sherline equipment for my gasser a While back from black acetal (like Delrin)... still flying them to this day.... total time from raw stock to finished part is well under 30 minutes.

what would you charge to make a gear similar to the ones pictured?

Depends on the gear... straight cut are the easiest, for these (Century Radikal) I used to charge about $60 for the set, and I made no profit once time was taken into account (Drawing, CNC coding, test and setup) though the actual cutting is fast once the initial work has been done. So I no longer make parts for sale as most people are used to paying $20 per gear from Heli manufacturer and nearly all scoff at what it cost to actually have a shop make one
