Hi everyone!
I have been thinking about this thread for a long time before i decided to start it. So, here is a resume of my C1 Flowmaster evolution and i will post all my questions about the boat in this thread, in order to keep all the info at the same place!
I started like everyone would do with a new boat, i tried it stock for a few runs. The boat is running very good on stock setup, a 40mph setup out-of-box. Temps are great, as in they stayed at ambient temperatures running the boat in a normal manner. Then i tried running it much harder, and noticed the stock ESC were heating a bit on stock props(4:00min run at wot and they got at 105*F). And on that test run, i broke the two starboard props i had. Just like every C! Flowmaster owners. While searching for similar props, and could not find any affordable set, i came across these:http://www.hobbyking.com/hobbyking/store/__61600__Turnigy_3_Blade_Boat_Prop_R3P_x_36_x_13_1 pc_.htmlhttp://www.hobbyking.com/hobbyking/store/__61593__Turnigy_3_Blade_Boat_Prop_3P_x_36_x_13_1p c_.html. Swapping to those props got me an extra 13 km/h(8mph), putting the top speed at +/- 78km/k(48mph). But I'm a speed addict, so , i ordered a pair of those:http://www.hobbyking.com/hobbyking/store/__75392__Turnigy_XK2860_2730KV_Brushless_Inrunner. html. I want to go 4s and maybe 5s if the hull can take it. I also ordered a reversed x440/3, x442/3 and .013 flex to test at some point.

I also tried 4s on the stock motor, and they handle it very well(as in not even heating up). I don't know for how long they will last, but i suspect it will be a long time. This is very good!!!

I did some FG in the back part of the hull in order to reinforce it. I mostly did the flanks and around the hatch opening. For future owners, take a look at the bow section of your boat, some times, it is missing some epoxy at the joining edge, at least, it looks like that on mine.

For now, i will continue testing the stock motors on 4s, and when they will die, i put the 2730 kv in there and try 5s.

I received my props last week! A reversed x440/3 & reversed x442/3. I want to try the x440/3, but i'm not sure on how many cell. I'll be using the 2860/2730kv(can take up to 5s). I will use the x442/3 with the two CC1415-1Y 2400kv i have. But it will only be for the next season. Here are the x440/3 installed.135162135163135164

I went to the lake today! The boat ran great and was fast. But I hit some floating thing and my rudder took the hit... At least thas what i thought. The bolts holding the rudder to the bracket were tootight from factory and made the hull crack.135572135573135574135575135576I think CA glue will do the trick for this kind of damage. Any other ideas?

Well... CA glue did not work good. So i had to re-glue the mounting plate in place, and re-shape the rudder mount with 5 minutes gel epoxy. Next, sanding and painting the transom!135661135662135663135664

I went to run the boat today. i was running 3s on the stock motors,and two things happened. First, the left motor, looking at transom, de-soldered a connector. The motor temp was 91°F. Not hot enough to do that. What could have caused this?

After re-soldering the motor connector, i put the boat in the water again, and after maybe 2 minutes, the steering servo went bad. Do you think the two problem could be related? Or is it only a coincidence? The servo was a traxxas 2075 model.

Please help!

Thanks, André.
