Twin HOTR Options, need help from you smart people!

[Diesel6401]

I'm starting a build thread very soon with a 32" cat to replace ekos.I will be using Arc 36 55, 2800kv twins.ill be the test piggy for these motors.rpm will be 41440 on 4s.should run at least 65mph or so with the right props.

Will be following that. The nice part about the 55s is their price. The 36-65/75s are starting to get pretty high.

[LarrysDrifter]

They are a little high.I think the 55's will be fine,but tique and mudle know quite a bit.I try to build new set ups based on what's batteries I have.most of my stuff runs on 6s and my ekos ran on 4s.make sure to re enforce your hull good or it ll be in splitsville.

Yea those guys are good. I planned on re-enforcing with some extra layers of FG since I have so much of it laying around, think it will work or should I go CF? I hope I can just use this FG and be good

[LarrysDrifter]

I always use fiberglass matting(not the chopped stuff) and fg resin.cheaper than cf and plenty strong.

sweet deal. Yea that's what I use. I do cut up small pieces of fg into the resin for small repairs though and to strengthen existing motor mounts. Based on your findings with the 36-55s will determine if I re-drill 25mm holes in the mounts though. If they work ok I will try those motors out, if not I will re-drill and slap on leopard 36-74 1900kv on 5s in the boat. That should rock! What esc you gonna run with those arc's and what kv rating you looking at?

[LarrysDrifter]

If your boat came with 380's,the 36 55's will bolt up.19mm is 380bolt pattern and 540 is 25mm.I'm reusing ekos mounts and going to make rear motor supports.my motors are 2800kv on 4s and using seaking 120's.

I bought it in the swap shop, id imagine its the hk version so I'm sure its gonna have the 19mm bolt pattern which is y the 36-55s looked great for the price, bolt pattern and pole count. If mudl and tiq aren't sure they will work good that sucks. Waiting on your build to see what happens. What props you plan on running?

[LarrysDrifter]

Should start the build Sunday or Monday.using 36mm venom,38x55mm tfl,and x442's.id like to use outrunners,but I'm afraid they will run hot.I don't think motor mount cooling does much.ill try the arcs,and you can make your decision.I would have gotten the same kv, but in a 380,but they are out of stock.I kinda like to be the underdog and still put the hurtin on bigger motors and voltage.

[tiqueman]

Im only basing my comment on what was recommended, or not recommended, to me. I think Mudls advice is pretty darn powerful though seeing how is builds turn out. I wanted to copy his BJ26 twin build for my HOTR. His comment was it wouldnt be anything like the BJ and thats why he recommended a XL size can. BUT, it all depends on what your goals and expectations are..... 36-55s may be just what your looking for.

[blackcat26]

I agree with Tique the xl's are a little better suited. The L cans will work but xl's better. I was just choosing from the parameters you listed. Anyway get off your butt and buy the 10xl's that are in the swap shop as we speak........

[LarrysDrifter]

Not to take away from your thread Diesel-but damn!!,I bought the wrong motors?(36x55)

[BakedMopar]

Youd be better off with xl two poles than l's in four poles. Don't be affraid of the Feigaos. I have just as much bang for the buck with these than my big dollar boats.

JMHO

BAKED!!!! another darn good XL build in a Skunky hull

Thanks Baked.The 36x55's are already in the mail,so Ill use them.To get back to Diesels thread,I hope he buys the Feigao XL's.Id like to compare the two brands and two and four pole as well as length.Im sure both will do very well.Is Diesel still here?Havent heard from him.
Id also like to thank Tigue,BlackCat,Mudl,and Baked for thier twin information and suggestions.Im learning from this thread just as Diesel.

[Diesel6401]

I'm still here bud, just reading and been looking. I am leaning towards 540xl motors, but not feigaos (been down that road, want to move to next). I am leaning at leopard 36x74 1900kv motors with octura x442s with seaking 120's on 5s. The wife said the boat arrived today so once I get home I'll see what I have to work with. I wonder if the rpm will be too low though at around 35k, any thoughts on that?

By the way my goal here is low 60s and reliable.

PS. You not taking away, we both are building up the same hull and we can share our learnings, questions and findings on this thread.
