Glad to help.

How importmant is the washout on the wing tips of the Ace ARF "Seamaster " ? (BUILT NEW WING WITH OUT THEM )

I wouldn't put any washout.

Me Again...

The new wing is a foam core and about 67 " giving about 1000 sq. inches .... Lost the first wing in a take-off attempt to far off shore..... ( Couldn't see the attitude well enough ) . I love flying off the water but getting close to 70 and like slower flying planes ...
As a kid I grew up in a town wher the big flying boats would re-fule before going over seas ....

I have flown with thw new wing with out the wing tip washouts ... A little shaky for me....

How heavy is your plane? I have had 2 sea masters and really love the way they fly. I do not think washout will help a lot if the plane is in the right weight and balance range. It has pretty good flight characteristics right out of the box. I am interested in the foam core wing though. Who cut it? Are you using dual servos for the ailerons? Also what are your rates and how fast are your servos moving?

Going from a 60!QUOT! wing to a larger wing should make for a better wing loading unless the added weight overtook the added span. Do not know quite the reason you have a squirrelly bird. Mine, and everyone I know that has them, has a solid flying plane.

Hi Dave ....
Good to hear from you ....
My Seamaster with the new wing weighs 8 lb. 6 oz. with no fuel ..... I don't know what it would weigh with the orginal wing .... But the new wing with one servo weighs 2 lb. 8 oz. ..... I am using full strip ailerons but may change later to TIP type...

The apparent instability may be my fault .... I never got a lot of stick time before I lost the wing and I fly from a large pond and tend to fly to far from shore .... Lots of trees on shore .... How much does yours weigh ?

With the stock seamaster you were looking at 7lbs or less depending on the engine and radio gear used. If my addition is correct, and you have roughly 1000sqin, you are slightly less, about 2 oz/sqft, than the factory wing loading and that is a good thing. Is the new wing semi or full symetrical? What engine and where is your balance point?

Hi Dave ....
The foam cores came from " http://www.dbalsa.com/ " .... At that time it only came in 3 ft lenghts so I have two joins ... They have the same profile as the original ...

Tried to send pix of unfinnished wing

Well, looks like a good wing. Thanks for the web site, I see a lot there I like. Still not knowing the rest of your set up, all I can say is the following.
1) Make sure you have your c/g set at the right spot. (never mentioned if it was pitch sensitive)
2)Make sure you have the control throws set per mfg. suggestions until you learn the plane. (if your throws are more extreme then that will cause problems if not enough stick time on the plane. The Northstar is a perfect example with roll rate) Exaggerated throws can cause over correction problems and or unstable flight when input's are done.
3) If you have a computer radio, and the rates are good, you can always dial in some expo to slow the response down at and near neutral stick input's. With -expo in everything responds slower based on the % entered. You want full deflection then you just give the stick full over.

Hope this helps. I long to get another seamaster. When I am finished with a few other projects then I will get another one. I love mine and after a few mods had a really kick butt plane.

Hi Dave ....
I Had some luck with a couple of flights .... Still unable to get any consistent stick time .... It gets dark early up here now
and that part of evening use to give the best flying conditions .... Engine shut down on me off shore and I tried to turn her around to get it close to shore and she stalled and hit the water pretty hard .... ( By myself again ) ... Had to go off in a very small dinghy to retreive
it... Got me and the plane wet .... I had some damage to my front wing hold down mounting .... I did have her flying at a nice slow speed for a few minutes ....

Landings still seem to be swift though ... Getting colder here also but expect a few good days before snow-fall ... I may try flying off the snow later on ..... After reading my response to you about the wing I noticed that I gave you the wrong size .... The wing is 77 inches
not 67 .....

Have been flying the ACE ARF for some time now....have done a number of mods. They work for me and I have attached a couple of pics.

Please contain your envy when you see the colour scheme. I love hot Pink & Purple (LOL)

I originally had a .46 OS, but last year have Saito .72 mounted. I am much more pleased with the Saito. Quiet and reliable. Moved the receiver switch to behind wing on top of fuse after I had a few shorts (I had it mounted under wing, silly me). Have no charger jack, avoiding liability, and just remove wing when required to charge. Worth the effort.

I made a new engine pod for the tank, sanded some blue insulation and then covered with fibreglass sheets a number of times. Has a 14 oz tank, which I like. Was sort of worried about weight of extra fuel, but my fear was unfounded. Also put NiMH 2500 onboard to ensure my flight time would not be impeded now that I was lugging all that liquid.

The darn floats at wing tips were source of frustration. Water force is powerful, and is no surprise that they got ripped off on a recurring basis if I did touch and goes, or a landing that was less than graceful. Tried a number of things, but settled on making a seamless join with covering. I abuse this puppy now, and never have wings dig in and rip off float.

Perhaps my larger pod and wing floats dont look the best, but this puppy is a working mans plane. Great flyer, no more maintance, long flights, touch and goes without worry of wings. Why I should fly anything else is presently beyond me. I'm good for a couple of more years with this rig....

HI;Have a couple of damaged seamasters to fix.Am thinking of making a twin,I am partial to twins and can't find a PBY that size since the Kyosho is no longer around!Have new set of nacelles from a twinstar thinking they might work maybe with pair of 28 Mags.Have some bigger engines but these nacelles are not to roomy and fit only small tanks.I know I have seen mention of this conversion somewhere on here!Another thing one of them has the little wings?? that mount on the fuselage and are about 6" long.They are mounted with wire between them thru tubes int the fuselage,don't think theywere actually for the seamaster?Looks like the old clipper planes had them?Maybe can do away with the tip floats this way?One of them has been broken just in front of rudder was this a weak spot?Looks pretty thin there?Thanks!!

Hey all, I just finished putting a Seamaster together last night and have a few questions. First, what is your AUW ( wet and dry??). I weighted mine last night and it was exactly 7.5lbs DRY. From what I'm hearing this thing has enough power to handle the extra weight. I also put a .55AX in it so I'm thinking it will be just fine but I thought I would ask. My extra weight came from the bigger engine as well as I put a 16oz tank in it (the 10oz-er wasn't going to cut it for the 55). I also had to build a new nacell to fit the larger tank which added a couple ounces.

I'm flying it next weekend and I'm going to bring a .46AX allong with me just to see how it will fly on that too.

Thank you in advance for the info!!!

Hi All, I just bought a Seamaster ARF. The mods I read here will be of great help. If anyone can think of any more please post them. I will be putting it together in a couple of weeks. Flying off of water is great fun!!!!! I bought a 24 ft. pontoon boat just for this reason. But don't tell my wife.[sm=drowning.gif]

Thanks

Completed some renovations on my Ace Seamaster over winter (no more pink and purple)....sheeted wing and fuse, &amp; painted.. Sits a little lower in water, but gets on step as it always did and continues to fly well. WIll post video in coming week.</p>

Great looking plane. I have a two SeaMasters - both ARF's One with an old OS 51 Surpass the other with a newer OS .46AX The AX flies faster, but for my piloting skills I prefer the 4 cycle Surpass swinging a three bladed prop (the appropriatetwo blade would hit the cowl). Fora videoin flight see my poston You Tube:http://www.youtube.com/watch?v=wgf4SJeWsFA

Great looking Seamaster. I have one completed and I am ready to try my hand with it off the water.My club had a float fly last Saturday.I did not get to fly because I funish the retrieval boat and they kept me busy.i was not quite ready anyway.One of the other club members had a Seamaster and when he flew it I was shocked at the result. He is a good flyer and had a terrible time getting it to take off. The nose seem to want to stay in the water and looked and acted nose heavy.

Have any of you guys experienced that. If so, what is a remedy. It seems like it would need to plane out a little before you try to take off, but his did not seem to do this.Really sat low in the water.

I just want to have as much go right for my first flight.

Let me know.

Thanks,
Keith

Great older thread. I have flown a rebuilt SM with the landing gear. It seems to fly tail heavy or yaws in turns. Is more nose weight needed or ail rudder coupling required? The hatch in front is too small , did anyone make that larger? Too small and tough to get battery pack in the nose compartment.

Every SM I've flown requires active rudder coupling or a rudder aileron mix to keep the plane in a coordinated turn and not drag the tail in a skid.

Haven't flown the seamaster since last flying season. I experienced the same ,regarding the need to mix a lot of rudder in the turns. Also needed a lot of nose weight to balance. Will update in the future. I have only flown off of land . Still looking for water.
I will néed to make the forward hatch bigger to get my hand inside so my battery (extra weight needed for cg) can be installed inside easier.
