700N Crash :(

[Gixxer]

I can't see how it would be the one-way bearing that 'seized'. surely its job is to remain locked (seized) whilst the blades are being driven, and seizure would only affect an auto??

[johnsandywhite]

Just a question. WHY would a locked one way bearing cause the motor to cut? I had a connection melt on my 550 Lipo. The motor stopped turning, luckily I run a 2s Life battery and managed to auto down with a locked OWB.

sorry to hear about the crash, man. I was hoping to see you at the field this weekend

For what is worth, I don't think the OWB could be the cause of the engine cutoff. My Trex 600N doesn't have a OWB, as long as your clutch assembly is smooth you don't even need a OWB on a nitro

D'oh. Not good. As Tony said, never seen the frame damage there where it has. I wonder if its because of the DFC head, everything being lower an all?

When I got my first nitro which was a Trex 700 the first thing I wanted to do was learn to auto and luckily I did as I had a few forced autos to deal with

One way bearing has nothing to do with the engine cutting out, The only downside to a OWB seizing up is you will have a hell of a job doing any auto's with it.

If engine & OWB ok, check the clunk line. Mine had a split & the engine stops pretty quick full chat, no fuel.

ill still be there this weekend dude just with no big helis hope to see you there

Sorry to see that. I have a box full of 700 spares inc frames as with my 2 700's I went for the turbine and gasser conversions. If you PM me a list of what you need I will have a ferret about and see what I have got. Everything will be new and unused and whatever they are on the web they will be half that price. Lets get you back on the horse again.

Then i have no idea what happend...it was defiantly a seize because the main gear is totaled! and clutch and engine are fine!

As said don't see how either of the one ways locking could cause the engine to stop. Either the main shaft bearings seized or the gear failed. Or the engine just stopped because of a fuel starvation and the gear got chewed somehow when the blades stopped abruptly in the earth.
If its any consolation my Logo 600 came unplugged as I climbed off the deck for an auto tonight. No buffer pack (dickhead) no control, watch it fall. Canopy, frames, blades, 2x6s 3700 Volts packs all destroyed. About £350 worth. Main gear survived though

[JoeBailey]

Could it be that that bearing block failed in flight, I've never seen a block do that in a crash the main shaft normally bends to a pretty good angle but the blocks are normally good.

That's a point. You don't have the same problem with a Brushless locked OWB as with Nitro. It's easier to turn a Brushless than a Nitro motor
