Status: offline 		I have a Hobbyzone Firebird Commander 2 plane. It is a nice beginner's plane and does well with no or very light wind, but is outmatched by even lower moderate winds. You may still be able to fly but the plane will wobble a lot and be erratic at times. At moderate winds it it easy to crash the plane. It just does not have enough "oompf".

According to the web site the plana has a 380 motor.

So I went to the local hobby store and asked how I can find out when browsing plane catalogs whether a plane has more power than another, and which planes can fly well in moderate winds. Of course I understand that this is a combination of the motor, the prop, the wight of the plane, the shape of the plane, etc. But just to begin with, wouldn't the "number" of the plane motor indicate more strenght (and I think for LiPo-powered planes these are different)? The store clerk said there was no answer for that.

But for example, the web site for the Hobbyzone Super Cub says "Powerful 480 motor for impressive speed and climb performance". Now does this mean anything? How can I find out which models will nicely cut through the fresh breeze of a California coast afternoon?

I am not asking for single model suggestions, but: how can I figure out which planes are strong enough when for example browsing hobbyzone.com?

Thanks for your suggestions,
Oliver

How much room do you have to fly? Small light weight planes do not typically like wind. They like very calm days or to fly inside. A heavier plane will usually fly better in the wind then a light floater type.

What type of plane are you looking for? Did you want a kit where you order the motor, servos, Rx and put it all together or are you looking for a ready to fly type setup? High wing, Low wing?

This is out of stock but can be bought from several other vendors. We have flown ours in high enough winds to get it to fly backwards.

Lots of stuff out there. Just need to shop for what you want, then ask questions about the plane to see what problems by be out there.

What I call wind is a typical ocean breeze, maybe 15-20 mph. I am not sure whether I would go flying then, but as I wrote, the Firebird Commander can handle just very light winds. Actually I flew it yesterday in a bit more wind and I lost it ... it disappeared behind some tall trees into an urban area, could not find it again.

I am a beginner RC pilot, so a high wing is definitely better. So I liked your Skytrainer suggestion, and the price seems to be good as well. The only thing is that I am getting tired of all these transmitters and was thinking to buy a serious transmitter (considering a Spektrum 6-channel) and then only buy PNP planes, or for Spektrum BNF, or whatever they call it. The Skytrainer comes with a receiver. Do you have another tip for a 4-channel plane with LiPo batteries and a brushless motor, which does not have a transmitter and receiver pre-installed?

In my area near Santa Cruz CA it is easiest to fly without a landing strip, just land in the tall grass. So a model where I can take off the landing gear and just land on the belly would also be good.

Thanks, Oliver

Status: offline 		I have been using a budget radio for all of my foam planes. It is the 9x. It goes for about $50.00 to $100.00 depending on where you get it.

Plus it will bind with the Rx in the Cessna. Same radio form two places.

I like Airtronics over any other brand of radio. They have never let me down.

Watch the sales and this radio would fit the bill.
