ProBoat BlackJack Twin Build

[mtbenjamin77]

I checked the potential COG with all the parts I have at thispoint and it came out around 28.5% So I should be pretty good. I'll have plenty of room to adjust the batts to fine tune.

Sp what have you settled on for motor KV and size?

I really think 3674 1700Kv will be plenty. I've see much larger hulls running twin 3674's and do pretty good.

My Cf parts arrived today, started building my stingers today. I have send off the CF parts to be milled. Here's what I have so far.

I got some work done on the stingers and motor mounts. I have the CF stinger epoxied in place now just need to mount the stinger brace. Then I can CF the motor mount in place. I am using a 4082 for my mock up and alignment so I'll be able to mount a 40 series if need be. The stinger is set at 0 degrees toe and trim

Excellent,good work man.

waiting for epoxy to setup on the stinger supports. Next in line will be the stuffing tube with oiler. I'm working on a design for the stuffing tube that will be removeable without damaging any thing. I'll post some pics when I come up with a good design

Ok tks..i got alot to learn...tks for sharing guy...you do very nice work...I work in a hobbyshop and ive been tryn to find CF cloth for myself and the guys in our boat club...none of our suppliers carry it in anything bigger than a few inches wide strips...and finding the plate or solid sheets to cut parts from is also non existant with our suppliers...if you get time if you could tell me the source for such things we would truly appreciate it.... I will be following your build closely...again tks ... DJ

[mtbenjamin77]

I purchased the cloth from kintecracing.com the plate comes from ebay but you can also get it from dragonplate.com. I cut the parts using a tungsten cargbide blade made to cut ceramic tile. Cut slow and do not push, let the blade do the work ya know.

Just curious, No adjustment on those beautiful stingers? What if they're wrong?
