Try some CorrosionX on the electronics. I've had great luck with this stuff. Before I used CorrsionX, water ALWAYS got into my electronics no matter how many layers of plastic wrap and/or balloons I used. Now I just use the red can CorrosionX and I don't care if the electronics gets wet cause they just keep on working.

The 6 oz. size is plenty. You may be able to get it at some Ace Hardware stores. Most aviation supply houses carry it, but sometimes only in 55 gallon drums. Several of us float flyers share one large spray can and its still over half full.

New Flight Shots


Got some new flight photos of my model today. I'm having a blast flying this model!

Nice photos Steve. That looks like a beautiful place to fly.

Steve,
Got a question-
Is the horizontal stabilizer also at a 2 deg angle like the motor?

Beautiful plane and you did one heck of a job with the templates and instructions. I know how much work that was!
I'm about a day or so from flying and much looking forward to it.
Thanks for your efforts.

Hoppy, the elevator is, more or less, the datum (0-deg). The motor (normally) has down thrust of 2-3 deg with reference to this datum. The wing might have, sometimes but not always, a +2-deg of incidence, also with reference to this 0-deg elevator datum.

If you set the elevator down 2-deg, it will mean that you have no downthrust, and the wing (normally 0-deg incidence) will have 2 deg of +ve incidence. You will find the plane climbing horrendously whenever you apply the throttle!

I see in the Assembly Drawing, it shows the motor and horz stab both at -2 deg. https://www.rcgroups.com/forums/show...mentid=2058823

Any other comments? I'm ready to glue.

Watts up
rclarkeingg's Avatar

Just sent the plans for print (Great plane)


Before I get started, can someone point me in the right direction.
I would like to use material I have on hand.

Will this motor work for this plane:http://www.hobbycity.com/hobbycity/s...less_Outrunner

Will peeled dollartree foam board work for this plane and would it be better then blue-core FF.
I do have one sheet of 14"x36" 6mm depron. that could be used for the fuselage and maybe the vertical stabilizer.

I think you would be a tad underpowered with that motor. I believe you'd want to see 230 watts or more on a 6/4 to 7/5 prop and at least 24 oz. of thrust based on flight reports I have seen.

Hey you are right. What I said is correct in general. Maybe it's different because it's a water plane?

I'd use the depron for the wing. You'll have to butt join it but that's not a problem. It's much stiffer than the $tree foam.

You're welcome for the plans, hoppy. Glad you enjoyed them.

Yes, I set both the thrustline and the horiz stab at -2 deg incidence, which together eliminates most of the thrust-induced pitching moment throughout the speed range. It's the negative thrustline angle relative to the wing that does all the work, by generating a down force at the tail that counters the nose-down pitching moment of the high thrustline. Best of all, it does this independent of speed. Having the horiz tail at the same angle as the thrustline puts the stab at zero angle of attack relative to the thrustline, which prevents the stab from creating pitch changes due to throttle changes. While putting the stab at an angle relative to the thrust line can also be used to counter high thrust lines, the problem is this is speed sensitive--you get different pitching moment changes depending on not only throttle position, but airspeed, too. By relying solely on the thrustline angle to counter the pitching moment and not the stab incidence, the Polaris stays in trim at a wider range of airspeeds and throttle settings.

Hmmm...that sounds like a good idea, eh?

Steve, the photos you posted further towards the top of this page are dynamite! Makes me want to build one, which is the true sign of a great photo IMHO!
