Re: Blue Bird K4

I'm in two minds about Du Cane's books. ... As an aside, would those with those books (I cannot find mine, house move) give me a list of Du Cane's qualifications, I fear I may have sold him short !! I think I know what you are saying. But considering the time when the book was published (1st in 195...

Re: Blue Bird K4

Joerg, best you and I keep away from mentioning how to alter Octura surface drive props to get the best from them we will send folks to sleep. :lol: ! Some of mine are so thin its a wonder they work at all. That's not to mention 'tipping' and 'cuping'. Its all a black art! I'm a bit beyond reworkin...

Re: Blue Bird K4

Very interesting information about the Hickman Sea Sled. That was new to me. I found some pictures showing how these boats looked, see attachments. There were single and twin drives. In a discussion why Sea Sleds are not more common, I read it was because Hickman had filed many patents around his id...

Re: Blue Bird K4

Crusader is what's known today as a Canard. Whenever people tried to run such designs they got either injured or killed, eg Miss Circus Circus or Taylor's Discovery II. Its the instable version of a triangle. With limited resources and trying to build a boat mainly from wood a design like Taylors Hu...

Re: Blue Bird K4

Back to K4: basically the boat looks like a roundnose hydroplane - if the motor and thus the CoG would be a lot more forward. So was K4 already a prop rider (surface piercing prop) or was it still a conventional speed boat with a submerged prop? Due to the motor position and no rooster seen in the v...

Re: K4 Bluebird

You probably don't notice, but to me the only reason to start this thread here and now is to belittle the archievents and the work of the BBP on K7.

Would you please stop this?!

Re: Donald Campbell's restored Bluebird in museum home row

Ernie, your position and interrests become more and more unclear to me. You are playing a very strange game. Anyway, if I were Bill or Mike or any of the volunteers of BBP, I would start right away tonight to take K7 appart, deliver all the original parts to the Ruskin door, nicely wrapped, with a r...

Re: Donald Campbell's restored Bluebird in museum home row

Ernie, I don't see you as enemy - both of us are just arguing and we both don't own anything of K7. At least I gave the little I gave as a gift without any restrictions. I still like to understand your view, as it seams to be the view of those who want to keep K7 stored in the Ruskin exclusivly. Wha...

Re: Donald Campbell's restored Bluebird in museum home row

Ernie, didn't you promise you would give us some good reasons why K7 should be locked away dead in the Ruskin museum and why this would be good for all the DC and K7 ethusiasts around the world? So far I don't see any argunents except: because 10+ years ago papers were signed that way. Were they rea...

Re: Donald Campbell's restored Bluebird in museum home row

I ran on 8s of 5Ah 100C+ LiPo batteries, not on 2s. The fastest single pass so far was 206.15mph, hopefully more later this year. I will give only some short numbers here (wrong thread). PM or email me if you want to know more or discuss. The boat is about 1.25m long, weights about 3.8kg and burst p...
