I use a Bungee that's 50ft of stout rubber and a 10ft leader of line to a ring. Its a quick aggressive launch with a very quick tow and the rubber always collects right at the stake. That's the way to go IMHO.

It's absolutely great when training alone. Can be scary when doing a side-by-side MoM launch with many pilots.

If there are 4 pilots for example with 17M separation between bungee's it should work ok... The line is so stout at launch that the model has no choice but to fly straight up the line. I rarely see the model veer off to the side on launch.

I'm more worried about the zoom part. Unlike in a real F3J mass launch, in this case all models would be doing the same thing (zooming), almost all aligned and at the same time.

Its rare that they are going to zoom 17 meters into another lane and the things is that your event like most are smaller so you can go 25 meters apart.

We fly a man in man format monthly here in Dallas, we use "class A" (hand launch) gliders with tow hooks. It evolved out of pain and agonoy assosiated with javelin throwing. It's been around for a while.

It's all up, last down, scored first down gets one point, second two, third three and fouth four points. If everyone gets the 5 min task, everyone gets the four points.

It's a scramble, you step up and fly, contest requires 6 flights. There is a means to resolve ties. It's a total gass, other clubs in Texas fly as well.

I've never seen a major tangle of lines....

I'm a big bungee fan for practice. Probably 1 winch session to every 5 bungee sessions is how it works out for me. 50' of 4M rubber and 90' of mono.

A MOM bungee launch seems fine as long as everyone has the minimum skill required to do a straight launch under some degree of "pressure." All it takes is one guy zigging when everyone else is zagging...

Agreed -

Your group needs to have all parties capable of an overhand throw - one of our pilots had a thrower for him. The thrower in question had never done the task (he was an F3K guy) He was just fine.

If your bungees are launching with 40 + LBS of tension you can't really go left or right - the model just goes up.

The assumption is that the model is setup to launch effectively - if your model is out of control for setup it doesn't matter what you use - chaos is more likely.

This format is not only effective but really fun and you get a LOT of rounds in as well.

Please rather consider Flying F3B next year, you know it is more fun than this dork landing stuff and we could use some more pilots in the US!

Man up and take the challenge!

I know its arguable, but "B" is more work than J. You need atleast 2-3 people to practice, you need different winches, you need planes that don't easily convert to other diciplines.... arguably (I know you flew well with the Fosa at the J tour event) Its not that I don't love F3B, I grew up and cut my teeth on F3B. Its just too darn hard to master your craft at unless you have a dedicated local team.

Hi Gorilla

I know, you getting married and stuff...

But Thomas Cooke and I practice a lot B just the two of us. We setup 4-5 winches and one guy is at Base B, the other flies 4-5 runs, then we rotate. Yes, it would be nice to have a thrower for a 4kg fully loaded B plane, but our practice works as is and you get good at throwing heavy stuff.

Just a thought, I know you would be digging that B stuff.
