Status: offline 		Twin setup on 6 s would be my choice,keeps cost down and you can still get into the 50s.The tp or similar motors would work fine and two will cost what one castle motor costs.I have two 5694 1000 kv motors im using in a 58" hull,hope to start the build in the new year ready for spring.I saw a video on utube of a guy running twin 4092 1390kv motors in a conquest cat the other day and hes getting 67 mph on 6 s,not saying id go with 40 mm motors but shows whats possible and you dont need to go hv.

I have two sat here ready to go in my 58 Apache,setup will be 6s,using t 180 esc,s version 3 with extra caps running cr 50 mm props.I know 6 s will get me over 50 a friend used 910 kv outrunners in his ,the 6oo size heli motors on 6s with cheap hk esc,s she runs 50 mph for 7 mins and hes had that setup for 2 years she runs great,hasnt even tried 2 packs per motor yet.I may go up to 8 s later and see how fast she will go but then id need better esc,s more ££ lol.

Sounds like we will see a few Apaches on the water soon, it just shows you can build a good boat up and not have sell your soul to the devil lol. I am going to give the t180,s a go, they seems to do the job well, good idea to add the cap bank. What rotation are you going to setup on your props, I am not sure what to set my to yet.

Status: offline 		From what i do know about prop rotation using my hulls is inwards creates wierd handling,outward calms the handling down and the boats run smoother.The guy running the twin outrunners tried both ways and he likes the outward rotation much better and another friend running an inline k600 gas motor with a splitter gearbox also found the same he tried inwards first and ended up swithcing and she now runs much nicer.I can post a few videos of the electirc one if your interested.
Mart
ps the esc,s came with the extra caps,version 3 has them so if you buy any ask for version 3 those are the ones i sell and i cant keep up with demand lol.

Hi Mart - I've been looking at the new 59" Outerlimits SV that Rick just came out with at Central RC and even though I am a "gasser" guy have thought about doing one in electric. I would like to see those vids when you get time to post them.

Thanks,

Phil

Cheers mate, are you going to run struts or stingers on you twin build, I though about stingers but think because the mounting bracket is so low on the transom ,you will have to mount the stinger higher to keep the end of the bracket from sticking out the bottom edge of the transom ( if that makes sense ). At least with the strut the bracket is out of the way and you can mount the flex shaft holder lower without worrying about overhang.

Mart
heres a cpl of vids of Pates twin using struts and as yet plastic props.When he built her his aim was a cheap scale running boat arround 30 mph well as you can see he over achieved as speeds well into the 40s and i think top speed was about 50-52 mph.

Well i think its overkill,Pate started out with t600 880 kv outrunners on 6 s and was getting close to the same speeds (50mph)as with the himodel 910 kv motors in a much larger boat than yours so to me 10 s with twins is too much,a single fine.This is just my opinion but im no expert.

Very nice hull. I wonder the capabilities of your size especially on rougher waters. I have the 35" version of this. Can you show more photos (inside, transom) please?

 I like the FOUNTAIN P1 so I bought a hull + hatch and will run this boat with a twin setup, two outrunners FMT 3650 1700kV, 2 LiPo 5S 3500mAh to 4000mAh  batteries and 2 Seaking 120A.

And can I see the inside of the hull and a close up on the transom please.

I noticed you downtuned your power aspirations from 2 x 8S to 2 x 4S with a different spec motor. Why did you change it? Performance/cost balance?

You also have only 1 water intake on the rudder. Don't you need 2?

PS : Where is your post?

Status: offline 		Here are my posts. One of them has the actual P1 on the waters:

http://www.rcuniverse.com/forum/m_11316185/tm.htm

http://www.rcuniverse.com/forum/m_11318908/tm.htm

- So as you have now 2 of them, what is the center of gravity suggested for the Venom (as percentage from transom?)?
- Can you show the inside of both hulls when you have time please.
- Isn't it better to have on pipe at the very center as low as possible for the Deep Vee instead of now having 2 props at higher level. Also this will cause more weight on the sides as you will now have the engines a bit higher and on the sides. This could cause a bit more tendency to roll in my view but I'm not an expert. Just that the lower and the more closer to center, the better COG which directs better handling. You can always use one very strong engine and batteries placed at center and organize the COG as the hull producer would suggest.

I also remember from Gas boats that the more power you have, the closer the COG. So if your suggested rate is 32% from transom for a standard power set up, then 30% can be something to consider. On an electric boat it is easier to do by moving the batteries back or front if you left enough room to play with.
