Wow, samich..............................what is that 24pinion and 32 spur............i've always wanted to stick my monster system in a boat (its in my 3905 now) But OMG.............................i think the min voltage for the monster sytem is 14.4v, you might want to check it..................you may need to go 4s, but gear down, have some mercy, BTW i am predicting that you will shred, destroy, liquefy your u-drive on the first run, but i hope not. Keep us posted, i would love to see a vid.
P.S. - castle states that the monster 2200kv on 6s is equivalent to about 6 h.p. !!!!!!
its funny you say that, i took mine out of my 3905 for this project. my intent was to see how things go and determine if i should buy another mamba monster system or go with a 1/10th scale castle system. maybe around 4400kv on 2s. on a side note i try not to show any mercy to any of my rc's. as for the 6 hp on 6s i believe it. my emaxx will do backflips spinning big joe 40 series tires on 4s. on 6s it just starts breaking things. and its a 23/28 gear combo your looking at in the boat. i may go to a 18/28 depending on what happens during the first few test runs. as far as liquefying parts goes i have the castle link on my side. im going to program the esc's traction control feature so its not such a brutal hard start.
honestly though the trx .15 marine is rated at something like .49hp. even if my mamba only made 1.5 or 2hp the performance of the boat would double if not triple. i was bored so i decided to mix it up alittle. after all thats what this hobby is all about.
i should start testing this weekend, i will try to post a video if i can. i still haven't decided on a prop yet. i think im just going to buy a dozen different plastic ones and see how far i get. after i find a good one i will switch over to metal.
