I am sitting at my desk making a drawing for a landing cradle for the HCS Broadcast 360 and I'm wondering how many of you guys that are using camera mounts with retractable gear have made cradles that you can land in in the event of a retract servo failure. I know that the chances are very slim that the servo, servo arm or the pushrod would fail, but if they did how would you land the model if the gear is up. Please don't tell me that you would have your helper-camera man run underneath the heli and grab hold of the mount as you spool down the rotor head...cringe cringe.

That would be a sad sight to see someone land the model on the camera and watch it roll over and destroy it's self. I have flown the mount several times, but I have never filled the air tanks because I saw this potential disaster from the get go. Tomorrow I am building a triangle platform from 2x4s with foam pipe insulation around the top so that in the event of a failure I will still have a place to land. On the lighter side I don't think that I will be shooting any autos to the platform with the landing gear up.

Heres a simple idea, why not attatch a light weight spring to the output arm of the retract air valve control servo? If I understand right, the retracts themselves are designed to drop down in the event of a pressure loss, but theres no guarantee they will if the servo goes caput for some reason. Something as simple as a little spring would do the trick, and it doesn't need to be very heavy, just strong enough to move the arm is all kind of like a throttle return spring on a gas engine does. The emergency landing platform isn't a bad idea either.

Go for it Wayne - I've now landed my B360 with the gear up a total of 3 times!!!!

None of these incidents were due to gear failure. The main cause of a failure to lower for air retracts would be servo/air valve problems wouldn't it?

All of my 'arrivals' would not have benifited from having a landing cradle available but if you do come up with something neat and simple I may just be interested in copying it

By the way, with the gear up, you will hardly know the B360 is there and it is capable of smooth stable fast forward flight. It's a heavy mount but works great

I use a two piece rolling tool box from Home Depot. I discovered that each piece is just tall enough to support the heli with the gear up and prevent the gimbal from touching the ground. They're sturdy enough to support the heli.

So, my emergency procedure is to have the camera man set them in place for landing in the event the gear won't extend.

It sure is a nice feeling to see 'em come down each time!

How about a sturdy tuperware type tub, It's deep enought that the camera will fit inside, but yet strong enought to hold the heli up, Like you said your not going to be shooting auto's to it, and if the gear fail to come down, you could land softly on top of it to save your heli.. and you could put some weight in the bottom to make sure that it doesn't move around while trying to land on it,, Now I know what your thinking, but I have some that are pretty sturdy,, tought enought to hold a 23lbs heli up,, Just a thought,,, Keep it simple,, XGM

Sorry, I've been on the phone with Dwight Schilling for the last two hours or so.

Yes Hector, that's me. I'm exploring the possibility of getting these helicopters to make extra money instead of just sitting around collecting dust.

The spring wouldn't work as it would load the servo and cause high battery drain and it would have to be a tought spring to pull a non corless servo back. Not to mention when some servos fail the tend to run to one side and freeze.

I have a 12' Makita compound sliding miter saw that I have had for almost two years and I have to invent ways to use this thing or to help justify buying the dam thing. My house has valted ceilings so doing crown molding is out. You all know how guys are, we like to aquire lots of tools.

I was just curious as to how many people have an exit strategy in the event of this type of failure.

If your Car has a sunroof, have your camera operator open it and land in there, should be big enough to the gimble to go through!!!!

Wedge has the right idea

My support vehicle has a large sunroof opening. We use it for an emergency landing with the retracts up. I've tried it (non-emergency) and it works just fine. The camera man sits in the car and grabs the camera pod as it comes thru the opening. I put a large rubber mat (cut out for the roof opening) on the roof so the heli doesn't slide around when spooling down.

Hi Doom, A portable Emergency Landing Pad would be nice if you were a long ways from your "Support Vehicle".
Walter, Dave L, just ordered that BME conversion Nitro to Gas 90 size motor,for his Ex. Can't wait to see it.
