Plastic gears & FBL

[blzkrg]

Can the stock plastic gears in the ds510's on the trex 500 handle the extra fbl stress?

i lost my right alaron servo in flight because the gears striped. not sure if it was a fluke, or just to much load on the gears. it caused me too crash - very frustrating losing new parts to stupid mechanical failure.

Thanks

Been flying FBL with plastic gears for 18 months, no issues in flight...

The specs on the metal and plastic geared DS510s is the same, the only difference is the gears themselves

Same here. They've worked fine for me with 300+ FBL flights so far.

I'm having trouble seeing how they should strip in flight,. Maybe there was an incident on the ground or in transit that damaged the servo, but didn't show up until you were flying

Not sure either how someone can confirm a servo "stripped in flight" since it's way more likely that it stripped because it crashed.
Chafed wires, loose plug at the rx or fbl unit, etc would be more likely to cause a crash.

The 510s with plastic gears work just fine with FBL setups. Can’t imagine that a 510 plastic gear will strip in flight unless it took a prior knock somewhere. Quite a few of us have been flying them hard for years on various FBL units without incident.
The only downside to plastic gears is that they break in crashes, but after replacing a few it gets a lot easier and is quick to do.

something has to break, if you go to metal gears then something else will break in a crash, typically something more expensive than servo gears

Did I suggest metal gears?

I am suggesting metal gears! Just to get rid of the PITA plastic 510 gears that strip if you look at them wrong. NEVER had an issue stripping in flight, but 9 out of 10 times all 3 would strip in even the most minor crashes. The final straw or me was when I toook my 500 out for the first time after rebuilding all 3 servos and a gust of wind knocked it off my table and stripped all 3 gear sets. The metal gearsets just happened to be avaliable shortly after and for me is the best option.

As far as the "something has gotta break" theory that is why I am a firm beliver in metal gears plastic HD plastic horns. Much easier replacing a servo horn over gearsets.

But as far as the OP's question, never had an inflight stripping problem. And as others suggested if you didnt have some extreme binding I doubt that was the cause of your crash.
