Bluebird & Other Scale Models

[TAGood827]

Hi Tim,
Yes, they are still available. I will check on P & P and get back to you. Meantime I'll email some details to you if you let me have your details.

I'll ask for PM privileges as I'm a noob and can't do that as yet and I'd rather not post my email on the board. If possible, you could PM me and that may allow me to respond directly.

Thanks,

Tim

PM privileges become active once you've posted three times.

Thank you, Mike!

Hello Mike,

I've tried to send 3 PMs to Fred but they all show as still being in my Outbox. They haven't moved to the Sent folder. I am doing something wrong? I did get a successfully sent message notice with each message but I don't think they've made it to him as I haven't yet heard back from him.


Thanks,

Tim

As already DC used to know, records sometimes don't come easy and especially not as planned.

Last weekend in September we had as record event for RC boats in Munich. I tried to push the current RC record (using 8 LiPo cells in an outrigger design) from 314km/h = 195mph to over 200mph. On the first run the new prop threw all 3 blades - I had grinded it too thin. Second day was too windy. Third day I did one pass at 331.7km/h = 206mph, but couldn't back it up with a return pass. The boat submerged on start up and came back upside down. Soon after the wind picked up again, so I couldn't do more runs.

We did set some records on other classes though, e.g. Arne raised the 6 cells outrigger record to over 300km/h = 187mph and Gunnar in 8 cell catamaran to over 230km/h = 143mph. Powerwise and also concerning stability Arne's and my boat could probably go faster - but both are on the edge concerning lift: the boats fly too high, so we are loosing thrust from the prop. So, back to the drawing board...

How about an inverted Aicraft-style wing at the front that is adjustable, It may help to keep the nose down a tad?

To what extent it will work, I do not know....

[JfromJAGs]

The whole boat is a wing and works in ground effect as a self stabilizing system - which we want to keep. We are working on some small changes in several points to reduce the general lift gently. Adding (inverted) wings or spoilers tend to disturb the stability of the system, e.g. an inverted wing in front will produce downforce as long as the boat flies parallel to the surface. But as soon as there is some angle in the hull, e.g. from running over waves, then the downforce will reduce or even change to lift -> dangerous. We will most likely install some (rather small) deflector plates behind the front boom - this less to produce direct downforce, but rather to direct more air over the center section than having flowing underneath.

Finally finished!

I was wondering, do you guys do these models entirely by yourself, or are there Bluebird kits? I've checked Scalemates for kits, only to find that many Bluebirds had been replicated... by ancient brands that have ceased their activity several decades ago.
