What are you visualizing as "long run times"?

4 minutes on a FE boat is a long run time.

2 4S packs in parallel will increase your run time, just be careful not to hook them up in series for 8S

[Jason4636]

Yea I know to hook them in parallel

[Stinger9D9]

That much weight will slow things down a bit too.

Speed and long run times - when running at basically full throttle full time, just don't go together.

Like Doby said 4 minutes is long - depending on the boat/setup/prop/water conditions, it could be a really long time. If you want to baby your lipos (and not take more than 3500 - 4000 out of a 5000mah pack) you may be only running low 3 minute times.

I never really noticed it to be honest. It's a pretty frantic - very entertaining ~3 minutes and if you just carry a few more pairs of packs with you, off you go again.

Dolby is correct !
It will work with extra batteries, it will possibly be slightly slower.
You may have so much fun due to longer run times , you may not even notice the slight loss of top speed.
On a M. Crew a single 5,200 mah battery fits just fine,
a pair of 4s 5,000 mah cells would indeed increase run times- if they will fit under the hatch....


I own an Offshore Cat that runs faster with 9s3p than with 9s2p.
Mine really truly benefits from the higher voltage of 3p.

So would you guys buy a 4s 4200mha? Like the ones grimracer makes? Instead of the 2s 5000 mha, withe 4s I would have 8400mha's. But how big of a speed decrease would it have, over the 2s?

[lenny]

Hi,
I had the same thing with more speed and more run time with bigger 4s cells in my FC 37" Daytona,
I was running 4s2p 30c 3000mah and got 42mph and 6 minute run.
Then I tried 4s2p 25c 5800mah and got 48mph and 14 minute run.
How much are the grimracer cells, Money wise ?
I think I have something batter and cheaper for you to try.

The batteries are around $100, I'm not set on which brand to buy? I know I don't want cheap lipos. I want a high C rating. Plus the demension and weight is going to play in on my choice. Is your Daytona, almost the same hull as the genesis?

[lenny]

Yes it is the same hull but the Daytona is a little stronger I think.
As for very good cells and not badly priced, I would get some Gen's ace cells 4s 30c 5300mah.
Do you have any other boats yet to use the new cells in that you may get ?
Just trying to think ahead for you, Before you say "Woulda coulda shoulda"

[Jason4636]

No this will be my first boat. I do have 3 helis. And one of them I can convert to 4s if I want to. I do like gen aces, I did fly them in my helis. But I switched over to thunder power. Gen aces are about half the price tho

Yes, For the price of one grim you get two gen's.
If you a race and money on the line than may be grim or thunder power would be the ticket,
But for having fun and bashing gen's would be great.http://www.hobbypartz.com/98p-30c-5300-4s1p.html
Do you like mono or cats more.
I like mono more I think and some choppy water.
This is my Daytona.http://www.youtube.com/watch?v=v6jf6...e=player_embed

I like the looks of a cat more. I like your vids of your cat. Man that water looks dirty.

[lenny]

Thanks, It still needs some paint.
The water is Cedar, And the iron ore discolors the water, and the acid deters the presence of microorganisms which might otherwise proliferate and clarify the water.
You can walk across this lake and the deepest part is 6'.
Cats look cool but mono run cool looking.
You should try to run some boats first, And than get one that you like.
Check around and see if any one runs some in your area, Do a search or add on Craiglist may be.
Then get one RTR or one modded off of hear or another site.

LMK and I will try to help you find a good deal on one.

Another thing to consider is in the case of a blow over with the extra weight in the hull you are more likely to have hull damage. Fiberglass is a little thin on the crew. I know this because my entire left sponsin cracked and separated. Boat is pretty much ruined. I would not do any upgrades on the motor the faster the boat the more likely to come apart.
