Hi,

Is it worth me trying to do auto's with the Protos or is it really not big enough? Am I going to end up smashing the under carriage?

fwiw..

Protos autos great..SAB blades are a bit better than Radix, imho...Heli rolls or flips in and out of inverted in an auto better than any heli I've owned, except for the Raptor 90...But that's another story...

Autos and inverted autos on a Protos no problem. Protos is much lighter than the T-Rex 500 and that reduced head loading makes it auto pretty good.

I was always afraid that the tight belt would hinder it's auto performance but it doesn't seem to matter that much.

I've done inverted autos with the Protos. It autos well for a 500. Thing is you pretty much have to nail autos with this size of bird. Not much room for error.

Research on auto techniques. Others can explain it much better than I could. Practice it on the sim until you're consistent. Then do it. Remember to go against the wind.

I have videos of doing inverted autos with my SDX, but not with the Protos. Here's a video of a regular auto. Just practice a lot. One bad auto with the Protos can break stuff...

Other than for fun, why would you practice auto's with the Protos? Nitro heli's - yes; electric helis??

On that line of thought, why would you practice autos with nitro helis either?!?!?!?

Because you run out of gas - blow a glow plug - break a fuel line, etc.

There is very little chance of the motor quitting on an electric heli.

good points, psych.

you can lose motor, but often also lose Rx control for same reason (fried ESC, etc.)

but I've broken a belt before... motor was fine, but it was definitely auto-time. rotor spun very freely, though... made it easier...

Autos takes precision and often times no chance of bailout for electric helis. Its often for show since it takes skill to pull one off, especially with this size of bird.

There may not be much necessity to know how to auto but in case of flight failure its really good to know. More so with nitros.

For me, its about the challenge of mastering autos.

Over heat an ESC, static hit that shuts it down momentarily etc...........Ron

question here guys... are you folks with electric helis consistently using UBEC's? If not, and the ESC goes, wouldn't it take the internal BEC with it? At that point you have no control of cyclic and you aren't going to be able to auto it down...

Side note: its pretty cool for show though!

On electric helicopters I have:

Sheared the pinion in half - T-Rex 500
Sheared the motor shaft off - T-Rex 450
Blown the one-way bearing T-Rex - 450
Blown the motor - T-Rex 450
Blown the ESC - T-Rex 450
Broken the tail belt - T-Rex 500
Pinion come loose - T-Rex 450
ESC Shutoff incorrectly set (motor shut off) T-Rex 500

I'm sure there are many, many others I have forgotten.

The worst is when the tail belt rides up on the rear pulley on the T-Rex 450 and jams in the tail case. When you hit throttle hold it just does a stop blade auto. Kinda sucks.

If you're using the internal BEC you would lose complete power if the ESC went out. Parkflyer BEC works fine and is relatively cheap. I'm using it on my Protos right now.

Going back to the question of the thread...

I don't think it's necessary to know how to auto with the Protos. The amount of accidental crashes you'll encounter while learning to auto will outweigh mechanical failures that will require you to auto.

Main reason to auto....???....They are fun!!...Between the 3-4 hardcore flyers in our group, we have literally thousands of autos between us...Do we ever crash...Yes, but rarely...Usually with the 450s, which sustain little if any damage...Give 'em a go..They become addictive....
