Maritimo build

[DISAR]

Well done, thanks.

cc240 x646 s/b/dt with 4350 hyperian 6s want to try the new g3 6500 35 c packs its on you tube under 6ofthebest1 it had a 1521 in it then some speed

[DISAR]

1515 1.5Y, 6s2p, 110 kph, Very good! What propeller, ESC?

[6ofthebest1]

i have a drifter m which is the same as what you have with a 1515 1.5y on 6s2p i ran 110kph i also ran a 1521 1y for the some speed so the 1515 is better with good run time you can run a 1521 2y on 12s1p with a low amp draw should be fast

Got the lipo's in today. Ill try them this weekend. These are shorter and wider wich means ill be able to move the cg back as well, (awesome). If these dont work, ill go with plan -b. New motors on 5s... What speeds are you hitting with yours? You also have to remember that both of our boats are just as beutiful on the inside as the outside as well as being stronger than most!!!! Yours you woulld see in a race and mine at the river..keep your boat as is ( clean ) and ( pretty). And build a speed demon ( simple ) and fast...

I think the key is power to weight ratio for this hull to fly, I'm building another Maritimo this time a single 12 cell beast super light and strong , want to go real fast this time! Bonewar

Well i pulled half the cf off the hatch and found about a half cup of resin in the hatch. So i carefully grinded it (all)out . I also pulled out my 4 aa batteries for the bec and replaced them w/ lipo batts. I know its not much but i also ordered some 30 c zippy's to see if this will work as is. I wont tear this girl down. If this doesnt work ill find a larger motor option w/ less kv and run 5s 30 c.. I know it will be even heavier, but this hull really handles well heavy ( i think).. Im doing 60 mph sitting super solid and i know it has alot to do with the weight. I think i can hit 70 mph with a diferent motor /cell cnt /prop combo.. What do you think? Andrews running a 1521 on 10's.. We cant be that much heavier..? Can we??

Wolf , Where are we at with that beautiful Maritimo of yours. I been talking to AndrewG about the weight for these cats , Both of our boats are to heavy , the goal weight for the hull to handle well is 3.5 kg , I'm 1.1kg over that , so I'm going to rip out the styrene in the front of the hull and replace it with air bags. I've been having a little trouble with the left side drive , lost a stub shaft and 1 of my x442(not happy) , I've got some friction problems there. I'll fix it buy making a new stuffing tube and better grease. Anyway need an update bro!! BONEWAR

WELL IM GONNA GO DOWN TO THE GARAGE AND PULL OUT THE ESC BOX AND CF PLATE COVERING THE WIRING AND GET SOME 30 C"S and see if this help.otherwise look for the 1.5d's up for sale ... thankyou for your input!!!!!!!!!!!

wont this also increase my amp draw on the esc's?

The 30C cells? Possibly a fraction, but they might get your boat out of the water more, which would probably cancel out the slight increase in current draw.

And when I say the motors are struggling, I mean pulling more amps than they would if they were running at max efficiency. I have only seen 1515/1.5Ds running in sport hydros and single cats on 4S, and running smaller props than 442s. You boat would definitely be loading up the motors more than those boats. 1Ys would lower the load, and possibly still pull the same loaded RPM.

the ready to run weight with batteries ( 4sx2 ) =12-14 lbs. i dont think 540xl's would handle weight =amp draw..?

[Rumdog]

Maybe some 10 or 11xl's on 5s? you could prop the hell outta those! Inexpensive too!

[wolf IV]

Their not, the batts are and the esc's are as well. I puffed a poly 5000mah 25c last run . I was thinking if i could get a little larger motors in it with less rpm it woul;d pull less amps... And i could rin bigger props and faster speeds? i know that my problem is the weight, and kv's..but i (really) dont want to loose any weight as its bullet proof...

[Rumdog]

I really have a hard time believing that the 1515's are struggling in this setup at all
