Another option is to buy all the parts you want and need to build your own. It may end up being as much or more than a fully equipped PNP.

i saw this site years ago. I still question if it will actually arrive lol.

I have purchased a few planes from them some years ago. All purchases arrived and back then, shipping time was reasonable - 3 to 4 weeks. Since they are based in Hong Kong, even throughout the pandemic, shipping of a plane isn't going to be any more problematic than anything else. And now that we're coming out of the pandemic, I think shipping shouldn't be a problem so long as you are willing to pay for air (2 weeks) rather than "ground" (upwards of 3 months). Large planes in boxes I've bought in the past couple months, have arrived within 2 weeks.

Yes, but not in foam. Build it any way you want. Might not end up being all that much cheaper if you count your time and effort into it. I've also seen it slope soared. You may even find some YouTube videos if you know what to search for.

I've seen one for sale on consignment in a local hobby shop. Again, the asking price is not cheap. Builders want money for their time.
OH, and they actually call it a Boeing 737. Boeing isn't going to go after a small shop in the middle of China. Could cost them millions and years and still get nowhere.

Has anyone ever seen possibly a glider version of this. Or maybe no electronics just the foam. Even if its a little smaller. I want another one to hang up in my garage but without the cost of the electronics or the wiring.

Finished painting and applying stickers to my AL37. Gotta paint the cockpit and fix the metallic silver trim on nacelle but she is ready for flight.

that is my next purchase. i've just run out of room in the hangar... :)

[jasmith41]

Hello all. I recently purchased a al37 to add to my collection. I own a spektrum dx8e and i purchased the spektrum ar8360t receiver. I have the plane built and i have verified all the control surfaces are functional. My concern is that im extremely unfamiliar with how to use this controller. It has so many setting that im scared i have possibly missed something in programming and binding. Does anyone have experience working with this receiver and transmitter combo. Any inputs on what i need to setup. Would like to possibly get safe activated.

i've been putting the ar637t in everything lately except the FW F15 b/c it need a 7th ch for the airbrake thingy. i've also added a remote on these bigger birds for $39 insurance. they seem to work just fine.

Thats very irritating to know, good but irritating. Those batteries were not cheap either. I think I paid around 180 each for them. Thank you for the info. Where is a good place to get them from?

https://static.rcgroups.net/forums/a...%20Results.Jpg Look particularly at the claimed C and then see what the real C is.
Based on the load test results, the following are some of the top rated LiPos ………….. SMC (direct from SMC in Florida), ChinaHobbyLine (US warehouse), most Graphine type LiPos test well. Not sure where you are located. If in the US, then it’s fairly easy to get most of the top rated batteries. If you are in Canada, SMC can be complicated but not impossible. I haven’t acquired any SMC’s due to the complicated way to get them. However, my best experience has been with the CHL purchased from any of their warehouses (5000mah, 6s, 65C “black” series). I also buy HRBs from Amazon. They have moderate C claims but their tested C is not really terribly diminished from the claims and they are easy for me to get. Their 6000mah, 6s work well for me in my EDFs. I use them in my AL and I also series them up with a 6000mah, 2s HRB in my 8s jets.

Spektrum 6s 5000mah 100c battery

They are, in fact, only 25C as per the 2021 load tests. A LiPo that tests that poorly, is not likely to give any decent flight times either when compared to other, better tested products.

Spektrum 6s 5000mah 100c battery

Not a fan of Spektrum Batteries. The telemetry with their ESC and receivers is nice but they're way overpriced and guaranteed they are nowhere near 100C. I think that battery weighs about 730gr. IMO, the SMC's are far superior, cost less and are a true C as per their labels. The SMC graphene 6200mah 6S 40C flight battery weighs in at 810 gr (so only about 80 more gr) and I guarantee you it's actual C is very close to 40C and higher than the Spektrum 100C (you can look up the battery test charts on RC Groups-don't have the link-but I'm sure someone else will provide it). I use these in virtually all of my EDF's now as well as my Corsair and Spitfire (12 minute flight times). You can also try the SMC 8100 mah 6S 20C (which actually tests out higher than 20C-which is all you'll need with the AL37) and it weighs about 895 gr. I use this in my F-16 and both my F-4's for flight times over 5 minutes (7 if you're very throttle management conscious) with virtually no degradation in flight performance (but then I'm using the 12 blade inrunner in all my 90mm EDF's). We've tried the SMC 6200 mah 40C in the Gulfstream (granted, not the FW model, but I'm sure it performs almost exactly the same) and IMO that's the battery for it, with flight times of 9-10 minutes, so I'm confident that that battery will work excellent in the AL37. Just my 2 cents.

Spektrum 6s 5000mah 100c battery

I only get 3.5 min flight times right now and land with 30 percent left. I dont fly wide open throttle either. Would like to see better times out of my aircraft, just not sure how to achieve it.

What kind of battery are you using? Some brands of batteries of the same mah, perform better and give better flight times than others.

[MeyerVW]

You would be better off using a parallel adapter to hook the two batteries together and then just hook up to the existing connector. It will likely get you more than 5 minutes but don't expect to double your current flight time using 1 battery as you'll be doubling the battery weight.

Will adding a second battery give me more than 5 min of flight time? The batteries would be 6s 5000mah 100c. Looks like all I would need to do is undo the Y connection from my esc's and run them individually. Right?

Here are some photos extracted from the maiden flight using a drone as a chasing camera.
Also you can see the video from this link: https://youtu.be/fac5T2A1mJs

Hello to all again. Today was the Maiden of the Al-37 and it flew great !!!! Photos attached.

I can see this being helpful. To adjust it now is quite a challenge with the planes size. I also see people are bypassing the bluebox. So far mine seems to be functioning where i dont think it’s necessary. I can say the retracts are extremely slow to raise and a bit slow to drop in my opinion. Maybe the blue box has something to do with it.

You would also be farther ahead of the game if you spend the time necessary to read all 109 posts in this forum. Lots of knowledge here that may help you avoid a crash.
Couldn't hurt, for sure.
