Put the bit larger motors on my 415. I used the 2212-10 motor (1450KV) w/ 8X4 3-blade props. Much better overall performance now! Here is a video taken yesterday of my flight. Notice how slow she can fly! I also was having a little fun in the air with differential thrust programmed in!

I used these motors: http://cgi.ebay.com/NEW-1400KV-Outru...item3cb72d6546

Or these are good too: http://cgi.ebay.com/New-RC-Hobbies-1...item19b5c51c87

ESC's were HK 20A : http://www.hobbyking.com/hobbyking/s...dProduct=15202

I would not advise to anyone to use the HobbyKing recommended motor on their CL-415 webpage. I tried them and I feel they were too underpowered. They worked ok, but the plane was "sluggish" in the air!

I was not happy with the fit of the forward hatch. This fit was loose and would have leaked water. I have made the mods shown in these two photos to force the hatch down tighter onto the fuselage. I also I plan to place some vaselene on the joining surfaces to help stop water getting in.

Yesterday I scouted my local ponds and found that my usual flying pond is now half covered with water lillies. But luckily I found a brand new pond that has no weed or lillies yet and has a perfect sloping bank.Today I took my floatplane out to this new pond for some practice water flying. I am glad I did as my water landings need a bit of practice to get back up to a good standard.

i'm also concern with elevator servo thanks to report...
will make cover for it

i'm also concern with front canopy... will modify with
higher inside border to prevent water in

i'm also concern with motor+ESC water dammage...
so i'v made near 100% enclosed motor pods:
My ESC's will sit inside the motor pod and i hope they
will stay pretty cool ? will see... (i dont use them as BEC
and are 18amp)

I'v set the ESC timming to high and motor start rock
solid... i wont take OFF before everything look 100%
reliable

What I did;

I removed the elevator servo and it had water in it :
when fully dryed it again worked normally ,

so I decided to take a new servo and fill the upper gear section
with petroleum jelly ( like you would stuff the shaft box on a boat)
then filled the bottem half with GE waterproof clear Silicone ,
this should make the the servo waterproof to where it is located
on the model

another small mod I did was to the water rudder I took an extra
control clevis and made my own longer less deep rudder from plywood
and mounted it on the clevis so as to allow it movement and not
break evertime it hit bottem - it also had a shallower draft and
worked well with out the use of D throttle .

baddb1, What if you add some splash guard to the hull to divert the splash outward away from the props? TW

Common RTV silicone sealants are bad news around electronics. They contain acetic acid (vinegar smell), which will corrode the electronics you are trying to protect. The silicone oils in them can also migrate, and since they are non-conductive, they can cause problems in switches, connectors, or pots.

There are special electronic potting silicones, but they are harder to find (a very good electronics store possibly) and more expensive than the hardware store silicone sealants.

Sure, that could be a solution. I had this problem on my Catalina and went to a 7X4 prop with no more water splashed into the props. So, I am thinking it could be just the prop actually striking the water waves and not being splashed from the hull...? I will try the smaller props and see what happens.

On the subject of water ingress into the hull,, after 4 flights now I have had absolutly NO water get into my hull, not even a drop! So the the stock setup seems to work fine for me. The hull and battery hatch area sits quite high out of the water which helps!
