A "no landing gear needed" recommendadtion, good for grass landing plane.


I wanted to know what a good plane for landing in a grass field would be. Its not the smoothest field either, kinda chunky w 5-6" grass. I was thinking of a pby catalina 55" wingspand???

A Multiplex Twinstar with a 250W - 300W brushless conversion and 7" X 4" props is fun off grass. Landing would be no problem but it might do a bit of mowing on take off. Apply some clear packing tape to the bottom of the fuz for protection.

Iv noticed that any pusher style does good with rough surface landings. My flying wing and FPV Drones are stable enough to bring it to around 5mph before touchdown so very little space is needed. My aircraft range from 30" to 60" wingspan now.

I had the wing come off my dual prop cargo and fly down my yard cutting two 9" wide paths through the grass... lost two good props that day, but gained a nice straight landing guide.

Is there any way to connect 2 motors to one esc and battery?

To one ESC? Its been done, but the conventional wisdom says no. One battery? No problem.

Hyperion sniper/Hacker super zoom.

3D performance with EPP durability. Belly lands easily without the landing gear.

I'd recomend what 732002 says. These planes can be hovered in and dropped straight down. Would fly equally well with or without the landing gear, as long as you keep the CG in the right place of course. These are tough birds and any damage can be fixed with a little hot glue.

An itch?. Scratch build.

You didn't say whether is had to be an ARF, or whether you were willing to build.

If build, and it is quite a simple build, I would recommend the Polaris, -

Polaris Seaplane Parkflyer thread

It will fly slow or fast, take-off from grass, even from water if you have any locally.

Whatever you pick, be sure to move the aileron controls to the top of the wing if it has a low wing.

Any foam model with a high mounted pusher motor is ideal for belly landing, no chance to break props on landing, check what is available here:

Multiplex EasyStar is a perennial favorite for this purpose (belly landings on any kind of surface.) Put some packing tape on the bottom of the fuselage.

"Polaris, "

I built one of those years and years ago, but it wasn't called a polaris. I don't remember the name it had then.

Still circling in sink...
The Parkzone Corsair (full-size, not micro) does fine on a field like that. I added some wedge-shaped "hats" made from folded aluminum flashing to protect the servo arms, and built it without the LG. Several dozen flights, still in good shape. Also any EPP or EPO flat foam 3D plane. Or a flying wing, as long as the aileron linkages are on top of the wing and not underneath.

And if you want something a little more stout then packing tape for protection, check out anti chip tape. It's the stuff auto manufactures use on the rocker panels, door edges, and fenders for paint protection. 3M is a major maker of it, you can get small sections at most auto parts stores. Or if you are silly like me you buy a roll of it.

It's a little thicker then packing tape, but way tougher. I use it on all of my birds for those just in case situations. Like where the gear fails and sliding across a paved run way could tear the bottom off. The tape handles it just fine, and if you tear it up, it's a snap to replace it.

Even on the sponson of my water craft. Slips right over grass and dirt, and even the occasional asphalt and concrete.
