Blackjack 26 Dual

[blackcat26]

Too much is never enough....lol My maiden did 61.1 mph. I'm sure the blackjack motors are stronger than the turnigy's, so hopefully this will boost me up. I have another blackjack that I have run on 6s and it does about 44mph but it is a single drive.......We'll see what happens! If this does not get me the speed I need imma throw down on some new motors.

Impressive run !
I like that the Turnigy 50mm motor will spin a 442. That gives me a bit of headroom with one of my new projects. Most of my reading tells me that the L size (60mm long) is better for 40mm props.
Again, well done, and I am keen to see how you develop this build.

I'll take the short motors off you if you want rid of them.

That doesnt sound right at all???? What prop and batteries were you running?
I ran 5S on a BJ motor and esc in a 32" cat, single drive, and did almost 50. 6S I would guess had pushed it at least in the mid 50s. On 4S people are getting 40-42 out of it. 2 or 3 more mph with an extra 7.4V seems like something was wrong.
What Im getting to is, I wouldnt let that 6S run discourage you and let you question speed.

It was a speedmaster strut with F.F. offset rudder running with a aquastar esc on (2) 3s flightmax (in series) 5000mah 40c batts on a x642 prop. That does sound slow for all that power.....I'm going to try the new wiring for this boat first and if that does not work go with the "L" motors. And yes the "s" motors are prolly not that great coupled with the 42mm prop!

After seeing Mudl's twin and Cog's twin I decided to try my hand at one. Went fairly cheap with turnigy Aquastar's and Turnigy 36-50-3300 motors on 3s lipo's per side. Props were s/b x442's counter-rotating with the Sv27 stingers. My port side motor was for a lack of description rattling instead of reving. I made few passes and gps'd at 61.1. I'd like to put new motors on without going to Neu's. My choices are Ammo and Feigao. Any idea's for hitting 70 and above?

Hi for hidding the 70

take aout yor motors
put in 3656/4
drive it with one 4s Lipo 5000 Turnigy/flightmax 40/50C for both motors,
or for going or flying very fast with one 5s Lipo for both motors

greetings from germany

mudl

ps:at the moment i drive a HPR CT04 with Lehner 3060/8 and 12s1P Turnigy 5000 40/50C.At the moment average amps are about 230 and peak amp is over 300.
Power is about 14000 Watts per motor.We checked the data with unilog systems.

[RCKong]

Now that is cool !!! probably could run an full scale electric car on that...

[RCKong]

I'm going with 2 Nemesis 9L's (2770kv) pushed by 2 CC 120's on 4s 5000mah 40c - 50c in mine, BJ 26 should be quik.

Hello

and this is my HPR CT04 Etreme Xhibit

Yea I just saved the pics of this to my extreme boats file. That is a VERY nice looking boat, awesome paint. I would like to see what makes it tick... LOL Any video of this boat yet?

Thank you sir, I just may try that! I cannot help but try the BJ motors first since they are free to try and the last time I checked Hobby King was out. By the way that video of your boat you posted on here that jumped the bank and went over the trees was amazing! One last thing.....Thank you for the inspiration for this project! It has and is very enjoyable! auf Wiedersehen

Simon, I've been running this motor for quite some time now. It performs like nobody's business. I've turned 42-44mm props on 4s with no issue and most of the time, it's still winding up when I get to the end of the straight. I'm not sure I would put it under the stress of pushing a mono, but it does great with the hydros with less slip. In reality, I feel that this particular motor may be a few KV higher than it states.

Besides, you can't beat $25 while testing.

[Rumdog]

I love the fact that the market is growing and we have options now. The Chinese stuff is starting to rank right up ther in quality and in some cases better. Especially in esc's and lipos!

[blackcat26]

I'm not sure my port side motor is 100% I noticed when powering up (just before hatch tape) that its kinda rattling and not spinning right like the starboard side. Flex is free spinning and motor feels good to the touch smoothness wise. It was getting warm while checking rotation very low speeds to make sure I had everything right. Any idea's?

Ok, got the BlackJack motors installed today. I am super pumped about this new wiring sceme! Thanks Scott! Can you tell me if my diagram is correct before I burn the garage down?
