Build pics of my Aeromarine Titan 33

did you cut the prop shaft? if not move the drive dog back as farr as possable and it should be ok. i use the hughly shafts which are tapered and only have a small contact and they work fine in the speedmaster stinger.. as long as everything is tight you ony need a small contact. can you wiggle it with your hand?

Nope, I didn't cut it. The shaft does fit snugly. I popped out the brass bushing and drilled a couple more holes in it closer to the end. I have a spare anyway. I think I just need a better motor and maybe a new flex so I can leave it a little longer so it can't migrate towards the motor if the coupler loosens up a tad, causing the drive dog to contact the stinger. Would the Neu 1527 be the best choice if I can scrape up the money? That 4" can should handle 6s better that the smaller ones like the 1515 or 1521 right? I was thinking the 1500kv 1.5D Thanks a lot to all you guys for helping me out!

well i am building a 31" mono right now, setting it up with a 1521 1.5d on 4s, i have never had an issue running 1515 1y's in the delta 32" cyber running mid 50's. as far as 4s/6s it is not the size of the motor but the kv rating. a 2000-2200kv motor runs 4s while a 12-1400kv motor runs 6s. the end result is the same rpm. your total target rpm should be around 30,000 (1400kv x 22.2v = 31,080 rpm, 2200kv x 14.8v = 32,560 rpm). the reason that the 1527 1.5d is good on 6s while the 1d would work on 4s, it goes from 1.5d @1500 to 1d@2300
i think a 1527 would be alot of motor in that boat.... probablly better with a 1515 or 1521. if i were in your shoes i would for sure look at the leapord 2000-2200kv or castle 1515 1y. i am sure both of those would push this boat pretty good.

ps: i have also never had a problem running 12-13xl feigaos with the etti 150 on 6s, that was a great set-up in a 32" cyber storm that ran solid in the low to mid 50's. i see your run tmes of 30 sec, 30 sec and then 2 minutes. that is 3 minutes on batteries, that is about the max you want to go. i would run this one for just under 2 minutes and it would be around 130+ degrees. have you checked to see that all your connectors are good, properlly soldered? that will build heat. what batteries?, cheap 20c's will build alot of heat. it sounds like there is something going on as i ran a 12xl 6s for about 20 runs with no probs before going neu..

My newer Titan 40 runs a Neu 1521/1.5D, Hydra240LV and an x450 on 4S2P. The setup is dead reliable, another club member runs the same boat/setup, several others the same setup in different monos. Lots of fun and all the speed the hull can handle. The boat runs mid-50s and is as far out of the water as I want for a race boat - running on the back 4" with no chine walk. I had to add over a pound of lead to keep it on the water, the Titans all catch a lot of air.

Another option (other than the Neus and Castles) would be a Leopard 4082. I have the same mount you do and just changed the rear aluminum peice to one from the larger leopard mounts. If you drill a hole further back to bolt the rear peice to the mount, you can use the XXL 4074 jackets OSE sells. They cover the 4082's well. I've ran mine with a s225 prop at high RPM (1600kv/6s2p) and it's been impressive so far. I imagine the Castle 1520's would perform well also but Im not sure how they would fit.

Cool, thanks! That sounds great. So Maybe I don't even need 6s, although I already bought 4 -6s packs. OSE has the 1515 1.5y in stock, but not the 1521. Is the 1521 worth waiting for you think? Got any more pics of your titan? Looks great! And thanks for the input!

Thanks for the reply! Wow that boat is full of packs eh? Looks like a cool setup. I was looking at the panthers, but I'm guessing the Neu has to hold up longer based on price..?? Sure hope so anyway. I'll probably have to do the same thing with the rear mount that you did w/ yours.

The packs are 30c so that should be ok, I'm not great at soldering, but I used 6mm bullets and melted plenty of solder into each, and held the gun on extra long once I put the wire down into the bullet to really let everything melt together well...I hope they are all good. Maybe I should just ship this boat to one of you guys who know what you're doing and pay you to look it over. Maybe I bit off too much with this project....

Or you could just sell it and buy something all set up... lol.... I love titans!!!

Man I got to tell ya. I really don't like the looks of these because of the lid, but bro, yours looks killer!
great looking Titan
I was going to do a DF33 or 39 but now I think this Titan on a 1520 would look good next to my T29

I went through and looked over the wires and I did find a way to eliminate 2 connectsing from the leads that come off the swordfish 240 ESC and go to the batts. I had the ESC so far up in the nose that I had to add a 4" extension onto the + & - leads. I moved things around and got rid of the extensions. That might help a little. i was also looking at my packs from what you said about 20c adding heat. My thunderpower 3s 5000 packs are 30c/ 50c burst but my SMC 3s 8000 packs are 20c, though i haven't had a chance to run the SMC in the boat yet.

Ok, so I just got off the phone with Neu/Castle and for my boat on 6s they reccomend the 1521 1.5y 1050 kv or the 1527 in a similar kv. That was around 23000 rpm, but i thought i wanted more like 30000 rpm? no? I just want the boat to go about 40 to 45mph and to have nothing get hot and burn up...so confused.....

low 20K for rps is a good sport range, the closer to 30K and beyond is entering into SAW country and big amp draws etc.

Personally, I would listen to racers on OSE than Castle Motor support who know best about cars, although I am sure there are some who know about boats. If Jay (Fluid) suggests or condones a set up, then you can definitely trust it.

Ok, so not too bad. I was trying to go off Jays setup, but was just unsure of the differance between his 1521 1.5d running on 4s and mine on 6s, so I think the lower kv 1521 1.5y should be about right for the higher voltage. I hope.....
Also I only had about 3/4" of my stub/prop shaft in the end of the stinger, which i don't think is good, so i just ordered a prather with a longer 3" stub so I should have about 2 inches in the stinger now for better support especially at high rpm.
I am starting to feel like I have a tiny grasp on this now anyway. I have a bad case of ADD so sometimes a new concept needs to be pounded into my head. Thanks again for not giving up on me yet!

don't worry bro, we are here for ya!
