    Hello, I currently have 48" planes, mostly fly sport, some precision, some 3d. I would like to purchase a larger plane to fly with some 6s batteries I have laying around for my heli's. I have my eye on a 73" Laser 230s to fly electric for awhile with the option to convert to 12s or gas down the road. Does anyone fly this size with a single 6s? Can someone please give me some motor/setup recommendations? Thank you.

    I've never flown electric, mostly because I love the sound of an engine. Why not try a midsized gas powered plane? Maybe something like the very well regarded VVRC 40.

    Why not go with a 60" size? I'm running 6s 3300-3700 in all of mine and they fly very well. Better with the 3300. Not sure what size packs you have but my run times are about 6.5min.
    I'm currently putting together a 75" edge from extreme flight, going to run 12S, CC80HV, Motrofly 4330-216 (I think). I've seen videos of people using 8s with the 73" laser with a Hacker motor. 6s might be a too little go juice. I would recommend using what the MFGR has set up for their aircraft or mimic similar specs.

    I agree with @AKNick that size plane is too big for 6s - I have the Extreme Flight 60" Extra and use 6s - 3300 batts with their recommended power setup Torque 4016 motor. A friend has the AJ aircraft 60" Laser (same motor). It is a bit bigger and would benefit from larger packs. I have flown both and the AJ is unbelievable. No coupling in knife edge. Pretty ridiculous. Very forgiving too. The EF Extra is less forgiving but still flies very well. I also get 6.5 minutes of pretty hard flying with an APC 15x6 (xoar 15x6 beech has better performance) on 6s 3300 batteries with the Torque 4016 motor on the EF 60" extra.

    @dhal22 has a good idea also...

    I'm sorry I should have been more specific. This is a reply from AJ Aircraft:


    Robert

    You are right on the money the 73 laser is an awesome plane, especially for 6s 5000, also it fly's like a gentle bird, or it can do what ever you throw at it. either way fantastic plane one of my personal favorite's.


    Thank you

    Scott B

    Sincerely,
    AJ Aircraft

    I was wondering what others if any have used for 6s setup. AJ recommend the Motrofly 4330 but don't have any recommendations for kv.

    I really don't want to purchase a 60" now, then purchase a 73" later. I'd rather just purchase the 73", run electric, then convert to gas.

    Might be worth a e-mail to Ken at Subsonic planes. He hand winds his motors. on his website he sates the 4330-400 or -435 on 6S with a 19X8 pulling 2700W, I got the 4330-216 on 12S pulling max 3200W with a 20x8 per the specs. From what I've heard 12S on a 7X" planes feels like a 60" on 6S. The AJ laser is pretty darn light for it's size so you may get away without stupid power (12S). I personally think 8S should be min for a 7X" plane - but I'm no expert.
    I do have the 73" AJ laser (There is an assembly thread I started a few years back on this site), it has a DA35 in it. Flies on rails. Very comfortable airframe to fly, predictable for a 3D plane too! Great airframe.
