Why? The setup works just fine as is.
Don't worry about wire length. You'd have to have awfully long (yards, not inches) leads to have any effect on the amp draw. Twisting wires is done to counteract the magnetic lines of flux that can induce currents in adjacent wiring. Some say it matters. In this case I don't believe it does.

If you do decide to shorten your motor leads, you can use the pull wire method or use a length of bead chain to snake through the areas where you want the wires to go. I do this often when installing long servo leads in a wing.

Thanks Mark. The only reason I am considering this is for airflow without putting holes in the plane. I really like the look of the plane as is and don't want to change it. The esc gets hot enough to get the velcro adhesive to let go which is pretty hot. Plus the motor sputters after about 10 min of flight with out full throttle usage and I fear it is not going to last unless I get it cool.

I think I'd upgrade the ESC before anything else. You can always use the existing one in a less demanding environment. More holes in a waterplane seems a bit counterproductive to me.

So what would you recommend as an upgrade from a the electrify 25 amp esc?

Does a bigger esc mean I have to change anything else?

1) A Castle Creations P25 or Tbird 36. Usually they are underrated amp-wise and are generally hard to kill in normal conditions.

2) No.

Good question. I've put my existing eflight 20 amp v1 under worse conditions than these and it's still flying.

Hopefully someone with electrical skills will point you to an esc that maybe is more effecient, therefore generates less heat.

Well I am a firm believer in CC Phoenix 25's. Thats what i run my P-38's with. I can get them for around $50 so that should work perfectly.
Thanks

Here's the Seawind at the 3DHS Fly Low In at Big D. The event was hosted by the 114th Aero Squadron in Dallas and was a great success. I flew the Seawind a number of times off the grass and showed those guys that "Edge" types aren't the only planes with some great moves. I think they were impressed with my outside snap-tumble-flat-spin.

Hi Kingsflyer,

You've certainly impressed me anyway! Is that an upright and level entry, snapping into a 'bunt' (outside loop for 360 in pitch) or a 'flick roll' for 360, with upright or inverted spin? Good job your wee pilots dont upchuck, plays havoc with the radio gear, is corrosion X good for that? regd's Al

I can enter upright or inverted, climbing slightly full bore, and cram the sticks up and into the middle - Full Down, Full left ailerons, Full throttle, full right rudder. Everything on high rates. Get some altitude and give it a try.

Well I tried to ROW yesterday. I got to the water and set it in. the wind at that particular moment decided to blow hard enough to take my hat off. I tried to just taxi but the plane would weather vein. Luckily the wind was blowing to me so i just waited. The nose of the plane did get submerged but all was dry inside. I will try again some other time.

Aileron in the direction of the turn to dig in a wingtip
high rate on rudder
full up elevator

should get u turning as good as you can in the water, unless you decide to increase the size of your water rudder

Cool

Did just what you said. The left wing went all the way under. Scared the crap out of me. It really was too windy. I was more or less hoping the wind would die back down like it was when I first go there but no such luck. It will be better on a calm day.

So I went to try ROW again. This time the water was good and flat. So I set her down into the water and tried to taxi out. Apparently you can't slow putt this thing out. You have to jam the throttle up and get it going before you have control. Also, something keeps causing twitches. Would one of my receiver wires touching an esc wire cause it. I found one touching when I took the wing off. Anyway I am going to keep trying and maybe one day I will get it.


Edit: Well I took it to our little pool here at the apartments and decided to give it a safer shot. I don't have much room but its enough to get moving to steer. Another 5 feet and I bet I can get it on step. So that little practice answered my question. It also thankfully saved me from loosing a plane. The prop spun off while I was taxiing around. 20 some odd flights and it finally decides to let go. SO a little thread locker later and it is ready to go again.

I have to hold full up high rate elevator even to taxi. I also use aileron to dip one wingtip to help taxi.
