37" Fightercat Daytona Carbon Fiber Catamaran LE #071 Twin 1600's

[jj2003]

This is the second of my hulls purchased from Fightercat. Another "CF" twin using FC1600's instead of Turnigy 1400's. I'm going to try a pair of Turnigy marine T180's but have another pair of 16s-200a's just in case. I've lightened up the hull and reinforced the transom and stinger areas using 2.5mm CF plate's. I've also used some Great stuff for windows to add floatation. It works much better than the black can due to its flexable properties and lower expansion rate. I've also gone with twin bottom pickups to provide the best cooling capacity for both the ESC's as well as the motors. Each motor and ESC has its own path of water with large water outlets to dump it quicker. I've added a triple layer of epoxy to the entire inside of the hull for added strength without the use of carbon fiber inlay. Still using wire drives and 110mm stingers with counter rotating 442's. Running on 6s with an option to run 8s, it should run about 65-70mph on some smooth water. Living next to lake Erie, it's hard to get just the right conditions. I usually can get them later on in the day just before dusk so I've added some exterior lighting with the use of some waterproof LED's so it should look neat. Here's the build pic's thus far;

Here's a view of the water pickups and the reinforcements for the stingers and the rudder. The 2 part epoxy from Illstreet works fantastic. Starts to reach a workable thick paste in about 25 minutes and ready to hold at about 30.

This is the installation of the LED's a few links showing it's operation using the 3rd channel of the receiver. The transmitter is a Flysky GT3B.

Those leds should look sweet reflecting off the water at dusk.
How did you lighten the hull?

do your props turn inward or out ward????

In my first build, Fightercat #068 (http://forums.offshoreelectrics.com/...tamaran-LE-068) I used both epoxy and CF/Kevlar fabric. On this one I used epoxy only and coated the inside 3 times by tipping and slanting the hull in different angles to cover the interior completely. It did add some weight but not nearly the amount of the CF/kevlar sheet covered in epoxy. Without weighing it I would have to guess at least 1-2 pounds.

Currently inward. It depends on what I want to accomplish. Inward is better on speed( say for instance, SAW racing) Outward is better on a round-e-round. Handles much differently in corners. Nice tight turns. Try swapping them around once and you'll see what I mean. Top speed on straight runs, inward. Handling in corners and tight turns, outward.

Ahhh, gotcha'. Thanks.

Learn something new all the time, I was wondering about that.
