Brad, Where in Orlando do you fly seaplanes? Man, I hope you don't fly in salt water!!

You could mount a lightweight foam wheel to the side of the fuse using a small machine screw and lock washer. Dip the screw in silicone or vaseline before attaching to fuse.

All fresh water lakes here, lots of them!! If I do the scale gear I'm also going to mount a Robart plastic strut cover.

Good idea on the foam...I know the stuff you are talking about. I have a feeling this plane will be a nice docile flyer... Big square flat bottom wing, 1000 sq inches... and flaps..I am hoping to make this a quick build.. Starting on it tonight, I am going to shoot for next weekend completion. Usually I am over-optimistic about completion times. I am thinking about making some false landing gear as well for the fuse sides. Probably after the maiden once I see how low in the water it's gonna sit. I certainly won't be using the "fake" decal gear, as the plane is really too nice for that. I see on the full scale the gear does just hang out in the open.

Power system plans are 2x Power 46 outrunners, 3 blade props, and 2x 4S 6000mah, 5000mah or 3700 mah packs depending on the nose weight needed, 2x Castle Phoenix 60's, and Ultimate BEC, although I need to double check the servo capacity on the ones I have used. This power setup has been very well proven over hundreds of flights on various .40 electric conversions. I have all the batteries, motors, escs, etc on hand already. Standard servos all around too. Should give me around 700-800 watts per side, total 1600 watts for a 10-12 lb. plane
You da man Brad!!!

Looks like the 13x8 Master Airscrew will be it. And even better, it is also available in a pusher configuration..so I can run counter-rotating props!! That should make the plane handle real nice.

I ran a test on the Power 46, I've run them in many configurations but always on 2-bladed props.

My results today are:

E-flite Power 46 (670kv)
Castle 60 ESC
4S 5000mah Flightpower Evo 25
Master Airscrew 13x8 3-blade prop

Full Throttle:

13.6 volts
53 amps
720 watts
7750 RPM

That gives me a total around 1400 watts, 10-12 lb plane (I hope)
= 116 to 140 watts/pound

That should do it.

Yep.

I knew the Power 46's would work. Now if Nitro can get their version back in stock.

Man you work fast!!

I don't know if this is a silly question or not, but why not just use a normal Rx pack for the servos and receiver and not worry about the BEC? Seems to me it would definitely help with any potential nose weight issue. Just a thought.

Sportflyer,
Thats exactly what I'll do but use a Duralite voltage converter to handle the the extra servos and volts from the lipolys. I have Duralites in two planes and they work great.

In fact I think you'll have no choice but to run and external pack since this plane has what....8 or 9 servos?

Only 6 servos for the electric setup. The instructions call for 9 servos glow, but I only count 8.

2-ail
2-flaps
1-ele
1-rud with attached water rudder
+2 throttle (glow)

I prefer not to hassle with a separate rx pack/switch. It's another battery I have to charge, monitor, and check before each flight. NIMH especially, with false peaks, etc etc...

I have had very good luck with the "Ultimate BEC" from Koolflight. I will have to double check the amp limit though. I'll be running 2 4S packs in parallel so I'll have redundant power supply for the UBEC.

I'm not 100% decided, but I may go with a 2S lipo with voltage regulator if I decide against the UBEC.

I've seen this debated before, and the general argument was have there been more planes lost due to a faulty NiCD or NImh pack, or switch, or lack of proper maintenance/charging as opposed to a UBEC? I have run a UBEC on my .40 size planes (and seaplanes) over 300 flights with no trouble.

I don't think balancing this plane will be an issue, as I have lots of battery to move around if needed.

I also run a 2100mah 2-cell and UBEC for voltage regulation my 1.20 Decathlon (electric) and that has proved to be a good setup. That's probably what I'll do on this one considering my ESC's may be exposed to water splashes, the length of the wiring to the batteries, etc..

Brad, Whew! At this rate you'll have the maiden by Sunday afternoon! Slow down man, I'm getting cold sweats!

Perry, I believe Raindentech has in stock the Extreme RC Motors you're looking for.

I'd have it done already if I didn't type so slow

Perry, you might want to consider a comparable Turnigy from Hobbycity if the ones from Nitro don't come in any time soon.

Very nice kit realy!!!
The only negative on this kit is that it's only water plane. The original one is
amphibian and should have landing gear. Of course i understand that the company tried to keep the fuselage in one piece because the landing gear
would obviously cut the mold in two. That in return would weaken the overall fuselage and would make impossible the cosntruction of an one piece fuselage.
I wish i could set up mine as electric too but my plane is way heavier.
Only the scale landing gear system weights almost 1kgr and that makes the model heavier.

The model i'm building right now has retractable gear as well as water tanks and can carry almost a gallon of water.
