catamaran power plant

Here are some question for expert... I know there are some around here :D

I'm thinking (only thinking for the time being!!!) of a new toy, my choice would go for a DrifterL.

I've been looking all around for different setup but most of the consistent info are in German and I don't understand anything of this language... SpeakenglishOrDie!

I don't really want to spend a fortune as this is just for sport, let's say 40 to 50 mph max would be fantastic (yeah I know 40 is different than 50 and requires different power!!!)

My idea was to start with 2 Feigao 10XL, probably geared @ 1,2:1 under 16cells max for the begining (in order to keep cheap non-HV ESC's already in stock), this would give a maximum of:
16cells*1.2V*66Amp*2motors = 2400Watts

I might go for higher voltage in the future if I go for 6S Lipo's and HV ESC's and then have a total power of 2800Watts

The most consistent setup I found is the 40" Admiral from Robby76 witch is exactly the same as I described

Considering that the Drifter is certainly a much better hull than the Admiral (if not, why does it costs that much?), does it sound interresting, correct, or away from reallity?

Robys power system is a solid setup. His hull is really the Kyosho hull witch is much better. You can save money on gear drives and go with the big KB45s. I think the 8XL is close to the Feogao 10XL and has the torque & rpm you need. I have read the Drifter isent the best handeling hull. I have never drivin one so I cant be sure. I chose the Jolly cat because ToysPort are known for quality. My other top choices where the M1 Super Cat & the Maritimo. I am not an expert how ever, but I do own a big cat & it seems to have a decent setup in it.
Good luck.

The Jolly Cat is only 35" long but what is your setup SJFE?

[ReddyWatts]

The KB45 will need atleast an 120 amp controller. They have more torque but are amp hogs that use from 70 to 100 amps. The Fiegao 1200kv motor used from 45 to 70 amps and the KB45 1200kv uses from 70 to 100 amps. It also reminds me of the size and weight difference in a 700sc and an 800 motor. It shouldn't be used in all applications.

[ED66677]

If I had to go for a KB45, I would then use only one!

I hear someone will be sharing a maritimo build thread in a few weeks! running twin kb458xl 120A esc's, should be interesting

[SJFE]

ED I run the KB8XL , Hex 120, S-BEC, X440-3 on a .78 wire drive. Powered by 4S-2P 25c PollyQuest EX @ 3300Mah. In 2 weeks the Hextronic 120 will be replaced with a Hydra 120.

That guy should pack up his stuff and head out east & run the big CATZ this fall.

A guy in the club runs a 45" HPR cat with2 8XLs 2 FDM gear drives, 2 CC HV110s and 5s per motor runs 66.1 mph on the GPS. here are some pics enjoy!

who is manufacturing/selling this nice toy?
when you say 2x8XL, I guess they are Feigao8XL not KB45 8XL? so that similar to Robby76's setup

[ED66677]

to SJFE, I had the chance to compare the Admiral with the Kyosho and there are no difference between these two hulls, the important thing is that Robby76 made important modification, according to what he told me (at least what I understood!) he sharpened edges of the hull and "added step to the steps", so for sure his hull is better than the stock Admiral

How many amp does your setup draw on the Joly Cat?

[SJFE]

Ed , Robby informed me the abs used in th KO hull is much thicker. The latest data on my power system is posted in the prop test thread.

the manufacture is HPR. as for who sells them Ask SaleenS7 I cant find the website I thought I had it in my favorites but I guess not. Yep 2 feiago 8XLs is whats in it.

[ED66677]

he must have pretty big gear ratio with the hight KV of the 8XLs, well depends how many cell he's running...

4-5ss lipos couldnt tell you the gear ratios though.
