BlackJack 55" Fast Electrisized

[JMSCARD]

I had a LMT 3080 rated at 459KV and it ran a x482 2 blade and X 470 3 blade without breaking a sweat!

High voltage and low kv=lots of power!

So what you're saying is you don't think the x470/2 is the wrong setup here Doby? I should have done a FE calc before I get to worries on the prop eh! Haha... I don't think this is any Lehner but it is a 580kv so maybe I should see how she goes!

[Doby]

I was running on 10S as well, not 12S....as the motor is an unknown, I would be a bit more cautious to start off. Also, strut height will help it unload more.

[Doby]

I have had a few of the earlier proboat hulls and would think that something this size and weight would definitely need re-enforcing in all areas. It wasn't designed for the speeds and stresses electric will put on it.

[Doby]

Also, I've seen the gasser version of this hull run....SLOW DOWN IN THE TURNS!!!!!!!!!! Doesn't take much to flip it.

In an effort to tame the blackjack I set my Trekker 800dfc atop of it, I think it helped let him know there was a higher power :)

And I've heard the same thing about the turns... I ordered the upgraded rudders from funrcboats that have water pickups to do away with the cooling line in front of the rudders, and I think I may do some big reinforcing in including CF plate the transom... I know it's not if I have a blowover but when and how many.

Big boats are soo cool unless you can't carry it, lol...

Oh, I wish I had the money to hire a couple monkeys to do pitting for me... The GF just can't handle big boat nor can I. Might twin out my old Geico hull... That would make me feel better maybe

If it makes you feel better ray this thing is a pia to just move around the house.... It's tall, fairly wide and 60" with hardware so it's def not a easy task to move safety without bouncing it off things lol... I think I need one of them boat bags lol...

Well.... if I got the 2nd Girl, I'd probably need a coffin too... I'm sure the same goes for Ray

I just saw a pic from Blackjack Sven's album and it appears reinforcement is a very good option. His cracked inside the sponson just in front of the tunnel.
