After seeing this online, I finally gave in a had to get one. Since Jumbo Jets are pretty hard to come by, it narrowed down my choices in the inexpensive catagory considerably. I was a little skeptical, but went with it anyway.

The box arrived, a little larger than expected. The product was packaged well and included everything needed for flight except 8 AA batteries for the charger. The assembly was very simple. The engines, wings and electronics are all packaged together, the fuselage being devoid of any controls or electronics. This is a 2 channel with no flight controls, all manouvers are accomplished by varied thrust of the engines. Again, I was skeptical.

The assembly went quickly, It's all EPP with twist fastener assembly, the 9.6 volt NIMH battery was installed and the engines tested. They screamed with authority! The launch uses a bungee system to get enough speed quickly. Again, I was skeptical as this seemed a little lightweight.

I went out for a maiden voyage. My normal area for smaller planes is in a rural and sparsely populated subdivision. Basically, I'm out in the country. http://static.rcgroups.com/forums/images/smilies/biggrin.gif I set up the bungee, hit the engines and let it fly. The plane swooped downward, barely skimming the grass. 20 feet out it gained momentum and started to climb. As it powered up to speed and climbed, it hit me...... this thing is too big to fly here! http://static.rcgroups.com/forums/images/smilies/eek.gif I did a couple quick circles to figure out how to bring it down in the field and did so with an Aircraft Carrier style landing. http://static.rcgroups.com/forums/images/smilies/tongue.gif This plane is capible of flying pretty high and far! So I packed up and went to my supersized flight field. I gotta say, this is the most impressed I've ever been with a "toy catagory" plane. It flies fast, far and looks super in the air. The thrust control works reasonably well, a tail rudder would be nice though. http://static.rcgroups.com/forums/images/smilies/wink.gif

Basically, for Between $120 and $160, You'll get a nice replica of Airforce One with plenty of power for long and high flights. This thing is pretty serious!

Two words of caution......... First, you'll need a big area to fly. Second, the bungee launcher must be stretched to it's fullest or the takeoff is aborted. I still think it needs a little stronger bungee. Hope this helps anyone thinking about getting one of these. http://static.rcgroups.com/forums/images/smilies/cool.gif

One last thing though, don't expect to do wild manouvers. you have to fly this like a Jumbo Jet normally flies. No wild rides that turn passengers green. The transmitter prevents a right stick unput of longer than 1.5 seconds. You can continually pulse it, but if you hold it in a contunous command for longer than 1.5 seconds it resets itself. The transmitter also shuts off after 4 minutes and you have to turn it back on. This is meant to prevent excessive draining of a battery pack and it signals time to land. To reset you simply switch it back on. (Hopefully that doesn't happen on a final approach?) I get around it easy enough.

In the event of a hard landing, the engines will pop free from their mount, minimizing damage. They pop right back into place and you're ready for the next flight.

The set comes with transmitter, bungee launcher , two battery packs, charger, a/c adapter and instructions. http://static.rcgroups.com/forums/images/smilies/smile.gif


Edit: The included bungee system works, but the stock stake is far too stubby to grab hold of the ground consistantly. 3 times, right at the moment I was ready to let go of the plane, the stake and bungee came flying back into my leg. :( The fix is to get a longer stake and drive it into the ground with a hammer. Once that was done, launch after launch was picture perfect.

The only downside is lipo upgrade will be tricky. The stock battery tray is configured for a long battery stick. A lipo mounting will take some creative work to keep the plane looking scale.

Hi Joe
Very interesting, what does this Jumbo Jet weigh ready to fly?

Thanks, Bob F

I'll weigh it first chance I get. ;)

Thought I would post a few pics.......sorry they are pretty huge. :eek:

The first one, my 8 year old holding it up before one of his flights. It's already got a few scars from some hard landings. It's still holding it's own after about 40 flights. :D

The next one, the camera is on max zoom and the plane is at a height of about 500 hundred feet. This thing will climb out nicely, it will go high enough for you to lose orientation.

The last one, the plane is a couple huindred feet out and on a landing approach. One of these days I have to get some landing gear. I've got to get this to take off and land from a hard surface.

maybe just get stronger ducted fans instead of removing the fan mounts completely and what motors are in an air force one?

There is no need to replace the fans. all 4 40mm fans produce plenty of thrust, the part that would need improvement would be the battery. A nice sized lipo with comparible weight would add considerable flight time. Past that, converting from differential thrust to active control surfaces makes these a great conversion. Programming a throttle limit would ensure the brushed motors would live a long life.

I wonder what the 9.6 pack weighs
might work with a 3s a123 pack 9.9 volts it think they weigh a 7 oz or a tad more though not postitive I just emailed maxamps to get the size and weight
2300mah should last a while

i was thinking that if you put stronger engines on it you might be able to carry a payload

the fans size would look too out of place if they were increased. The hot setup would be to convert to brushless motors. However, then we are talking 4 brushless motors, 4 speed controls and that adds more weight. I'm going to do that sooner or later, for the moment the brushed motors do a fair job even if they are only 130s.

Whats this like as a first plane?

A great first flyer as long as you have lots of room.

Does anyone own or have any info on the Estes xb-39 eagle eye? I heard some where that it is underpowered.
