TFL Genesis 56” best Prop?

[flexxb737]

Hi Guys just got a brand new TFL Genesis 56” Cat and am planning on running 12s batteries with everything else stock. Looking for advice on Props. I’ve sent DasBoata the original Two blade for polishing and sharpening. I’ve also asked him advice on a “Good” prop. Any advice on other good “Upgrades” for this application would be appreciated. Thanks.

go to youtube and see what other owners are actually running and their results on the same boat ....it would be a good starting point for you judge from
here is the first video listed with your boat https://www.youtube.com/watch?v=7wTo0d58V94

I would NOT recommend 12S with the out of the box setup.
Out of the box is setup for 8S, to change to 12S - you should also change the motors to something around the 750KV mark.
Also the props are designed for the out of the box setup - 8S with the motors that it came with.

Just because the ESC says it can handle up to 15S does not mean you should go there. The hull will NOT handle it.(NO warranty over 8S)

Thanks for the reply much appreciated. I'm fairly new to electric (Quickdraw 56" Apache Gas stuff before) but that's the advice I received from Sandy at MarineFE
from where I purchased the Boat! He assured me it could handle 12s easy, So I'm confused again! LOL
What brand engine would you recommend? I'm guessing I may have to upgrade the ESC's as well and if so what brand and size?

Thanks for any advice once again.

The ESC"s are OK for 12-S, they are rated up to 15-S each

I myself would first run it and get it setup the best that you can on 8-S

To change it to 12-S, first off I would take it apart and reinforce the hull and the seam all around the inside.
You also may need to reinforce the motor mounts, and the strut mounts.

Then you can decide on motors and props.

Reinforcing the hull and mounts may even be a good idea for 8-S

ED - Just to make sure that we are on the same page.
When you say 12-S --- do you mean using two - 12-S ( or four 6-S to make 12-S) Packs, giving you 12-S for each motor??
Or are you saying to use only TWO 6-S packs ( 6-S for each motor) giving you 12-S on board the hull?

Is this another one of those classic new guy cell count confusions?

What battery do you intend to run?
How many of them will you have?
Are they connected to each other?
- If yes, are they connected in series or parallel?
- If there are four batteries, the question above applies to each side. Are the two sides being connected as well?

[flexxb737]

Again thanks guys. The plan was to run 2x6s wired in series for EACH engine therefore 4 batteries in total (2 batteries per engine). Makes sense yes?? Ed

OK then

AS I stated above make that Four - 4S packs
Two for each side wired in series.

This is what the setup in this hull is designed for 29.6 Volts per motor.
8-S X 3.7 V = 29.6V
It is also probably designed for this weight setup also??

Two 6-S packs per side may be way too much weight forward, and never get the hull balanced to run properly.
Also too much KV for 12-S

Before you start changing things..run it as is on 8S as Larry suggested. Run it with the stock props once you get them back. To many people suffer from the "I wanna go fast" syndrome without even establishing a baseline with the stock set up.

Did the seller give you any idea of runtime you can expect? You might be in for a shock if all you are used to is gas.

As OP asked what is the best prop for a TFL 56" Genesis and as Larry suggested to start on 8S I think you should start with an X452/3. I agree with Larry on 8S and not immediately on 12S but actually i think you might be able to get by with running each side 2 x 6S in parallel and you'll get a longer run time. Assuming you only have 6S batteries you won't have to buy extra batteries and this will certainly get you around 40mph to maybe mid 40's if you're happy with that. When I first got my 56" Atomik ARC it came with a 120A esc, yes a 120A esc and an 2000w small outrunner for such a big boat and it ran mid 30's. I sharpened the X452/3 prop, rudder blade, made some adjustments on strut and got it to run 47.3mph. All this running on two 6S 3300mah 55C lipos in parallel. With a twin I'm sure when you get it set up right, with Dasboata prepped props and sharpened rudder blade and proper adjustments on the strut, you can get it to run close to or maybe even in the 50's stock. If not then try a three blade starting with an X452 and go up from there. But if you want to go much much faster then for sure start with 8S with proper adjustments and all before 12S just so you would know how it runs and if any heat issues before maxing it out. It's just hard to determine what is the best prop without knowing your goals and setup. . .Just my 2¢.

Thanks Again Guys. Bp9145 all noted. My thinking was why buy 4x4s batteries and eventually I would like to push the boat to its max and if I get the 6s batteries just run in Parallel initially and that would save $$? Would the weight of the 6s affect things much compared to the 4s though? Will discuss with Chris when he gets the stock Props. If I do go for the 4s or 6s what sort of mah rating size should I go for to give me a descent run time? Also my goals is to hit the mid 70’s in terms of speed! Possible?? Also Graphene or LiPo batteries as I have not purchased batteries as yet? Thanks for any and all suggestions. Ed

As I stated above the weight of four X 6-S packs in the stock location without rearranging and rebuilding the interior of the boat could be a big problem.

The weight of four X 4-S packs compared to four X 6-S packs is over 2.5 lb. more weight.

When you add that 2.5 lb. to the stock location, the hull is now too nose heavy, and will run like a piece of ----, and you will not be happy.

Here are the two pack makes that I would recommend (Both graphene).

https://www.offshoreelectrics.com/pr...rod=rev-ys5000

Stay with the 5000mAp packs.

Are you looking to race on the oval, or just sport running and some ZIP-ZIP for all out speed?

The 8-S setup with some tuning and props should get you over 70MPH no problem for all out speed.
Run time should be about 3 min. all out.

Also as I stated before, reinforcing the interior and the seam of the hull would be a good idea.
