Sammy,

All three sizes.
2S 120, 180 & 240.


I fly my Beast, Sbach & UM Stryker often.
6-7g is big.
Totally changes the way these UMs fly.

I don't even bother with the 2S 240 in my Beast anymore.
Light flies better.
The Hyp 2S 120 is amazing (for 4.5min) in my Beast/5043.

About all I fly anymore are the 120s & 180s.
Only plane that I really enjoy the 240 in, is the Stryker.

I don't mind the short flight times because of the flight performance upgrade.
With enough batts and fast parallel charging; the rules have totally changed.

Looks like I can get all three new UMX planes for $405.
Stashing cash daily.

Seriously though, I agree with you... More weight on the UM is not that good. My favorite flying spot is great, but landing the Sbach was a bit tricky. Landing the Gee Bee would definitively be a problem for me. (Though, for me, it's Beast for sure, Hyper Taxi maybe, and Gee Bee if there's ever any money left in early spring!)
At this point in time, I just don't have any pull to the taxi. I am not into any type of 3d flying, and want my airplanes to look and fly like airplanes. I am fine with my present Beast, so that only left the GeeBee. Maybe I am wrong, but as I said, my belief is that the first landing in my yard would rip the gear and wing braces off of it. Even regular gear like on the Beast and Sbach just grab the grass and flip the plane over and at the least bung up the nose and vertical stabilizer and sometimes worse. The little single cell 1 oz planes just stop usually without any damage but the extra ounce starts to be damaging and with the other extra ounce plus of the GeeBee it is almost bound to leave a mark as the saying goes.

It's not ideal, but couldn't you get a thickish roll of clear plastic to lay on the grass as a runway? I forget the brand, but we use 50' long by 25' rolls of heavy duty clear plastic on some of our concrete jobs. It re-rolls pretty easy and I would think you could make a fairly level surface on shortish grass. Any wind over 5ish mph though and you'd have to transport weights along with the roll... Maybe a few strips of that portable putting green stuff flipped upside down (assuming it's not bumpy like the backside of carpet).

I'm sure if you want it bad enough, you can make a solution.

It has to be staked or somehow stretched pretty tight or you get little hills and valleys that clip the prop whenever you take off. Same with a tarp, which I use quite a bit for my Beast, T-28 and Champ. I am considering investing in some real outdoor carpet (Astroturf?) as I think it would work better. Anybody used it before? Maybe the micros wheels are too small. I generally put "bush tires" when possible, but don't think it would be possible on the GB.

WSEN,

The indoor soccer court at which we fly has AstroTurf. The Mossie's wheels are large enough, and my Champ with 'tundra tires' has no problem - however, the stock wheels on the XP & Beast are much too small for reliable ROG takeoffs & wheel landings on the stuff.

How about a small roll of linoleum flooring?

How about a tree, that always worked for me when I first started flying.

Yeh trees work real good. But then you have to cut 'em down to get the plane
We put new laminate flooring in our kitchen a few weeks ago. Since then the old linoleum has been spread out in the yard. Not bad. Slick, micro needs brakes!

Wonder how big the wheels on the GB are? Might work!

I think it would fly to fast

My D model likes to be flown at a pretty good clip and if you try to land to slow it will tip stall on you. Too fast and it floats forever. My plane is a bit bigger though, 43" wingspan and 480 motor. My plane also doesn't like crosswind landings much if the wind is blowing very hard. It is a blast to fly though! and they do nose over pretty easy. I fly off a grass field though.

Gotta get one of these! I wish they had a bnf.

It is indeed Bind-and-fly - no radio included. Do you mean PNF?

You're turning into a penguin.

Grass Landings


My field is all grass, no landing strip of worth.

I take all the LG off my UM's, no problems belly landing.

But the GB and the beast: LG must stay!
Do any of you Beast guys grass land? is it possible?

I wonder if the As3x will allow for a high AoA flare drop down landing.

I was thinking about some kind of net type catcher. Like a loosely strung lacrosse goal turned around. Just bring it in slow and drop her in.

I am picturing a less straight down version of a high wire/trapeze guy falling into a safety net.
