Brake Systems?
Has anyone manufactured any simple brake systems? Also, what if you had two planes on one frequency. Could you fly them simultaneously? haha

RE: Brake Systems?
There are several brake systems out there, but none of them are simple. That's the reason why you don't really read much about them. You won't see them in wide use until you get up to large scale aircraft or jets. For most of the rest of use we get along with out them and learn to stop the plane in other ways.
Two planes on one channel = two smoking piles of balsa splinters!! :D No, you can't fly them together. This is why frequency control is such a big deal at all flying fields. If your plane is in the air and somebody on the same channel turns on you are going to lose control of your plane. Ken |
RE: Brake Systems?
Right, Right, but there is no way to synch two planes together on one frequency so that they act identically?

Hahahahaha, please put the bottle down.:D Scott

RE: Brake Systems?
I have an idea. Get two planes, try it and let us know how it works out.;)

RE: Brake Systems?
It's totally possible. But, you need split screen viewing.. meaning one eye goes one way and the other goes the other way, and you also will need the ability to focus on two different things at the same time. Oh, and you must have four hands. Yep, it's toally possible..:eek: Two heads will also work.

RE: Brake Systems?
You could use the same brakes as R/C nitro cars. But they would be heavy for an electric foam plane.
Or you could use a parachute like the bat-mobil :D |
RE: Brake Systems?
Dubro used to make a simple nosewheel brake part #157 .. Just a drum that tabbed into the wheel with a coil spring to apply friction when a cable was pulled..
We hooked it up to the elevator servo .. down elevator applied the brake. Rocket City was making them but they folded. You can sometimes find them on Ebay.. ohh like right now. There is one in this lot of parts. http://cgi.ebay.com/Rc-airplane-land...QQcmdZViewItem Hobby Lobby sells an electric brake from kavan but it's $57 Pn HLFK263 |
RE: Brake Systems?
I just don't see the need for it. I have flown some aircraft that get pretty darn fast and have never had a stopping problem - even with a paved runway. The only time it would be justified is with giant scale stuff or jets.

RE: Brake Systems?
Jet guys use pneumatic or hydraulic brakes but simple they are not. Jets are REQUIRED to have brakes by AMA.

RE: Brake Systems?
I've used that Dubro , drum and spring brake myself. We were flying from a 240' paved runway . There were alot of go- arounds. But that brake made many more of those aproaches "in the window" for a full stop. It was just fun to use it. And it was neat to hold the brake on and run up the engine. It works great !!! Very simple mechanism. There is a small coil spring that is wrapped around a drum brake. The drum has 3 prongs on it and you just stick them between the spokes of the wheel. One end of the spring is attached to the nose gear and is fixed. The other end of the spring is connected to your elevator servo via fishing line. Pull the line and the spring constricted around the drum. Braking was variable and linear. And the entire rig was very light weight. Just to be clear, you use only one brake and its on the nose wheel.

I don't remember where or the specifics of the how, but I remember reading an article (I think it is online) where the loop side of velcro was used as a light friction brake against the inside of the wheel. I wish I could remember where I read this, but I guess it could all be a crazy creation in my head full of ideas. Anyway, this would not be a mechanical brake just a simple friction brake to help slow things down. Has anyone else seen this?? [&:]

RE: Brake Systems?
A tight wheel collar will do just about the same thing if all you want to do is slow it down on pavement.

A very simple mechanism that works well. --- For those who don't know: These simple "kits" had a small drum that affixes to the wheel. On the wheel wire you install a small plate that can move against the drum. A spring holds the plate away from the drum. A wire is run from the drum to the elevator servo. When you push the nose down ( or up, it's up to you... ) the wire is pulled pushing the plate against the drum. These are lightweight ( .2 oz ), simple, easy to install, and effective. HOWEVER they are primarily designed for trike gear planes. |

But it would also slow it on take of - requiring a longer runway instead of a short one for landing. No gain.

RE: Brake Systems?
not if set up right take off would not be affected.

RE: Brake Systems?
I have a tower 40, and as you know it has very basic gear. I think I will just tighten the collars around the wheels a bit so the plane will not roll as easily.

Put a very short piece of fuel tubing on the axle to rub on the side of the wheel. Less damage to the wheel and makes drag adjustable easily.

RE: Brake Systems?
Be carefull if trying to use a friction brake on a tail dragger. Any friction on the mains makes the plane more likely to try to nose over, especially on landing.

RE: Brake Systems?
In my gallery are some photos of a system I have installed on a LT-40 and a Kavalier that work great and are fun to play with. I use the gear channel to apply them. Either off or on.

RE: Brake Systems?
Good idea and very simple.
