NO. Definitely not. It's my guess for a free flight scale model with that enginel, built light. You really need to check with a group that flies scale models with that kind of engine. And my guess is that most free flight scale fliers are using either rubber power or electric. As you know, glow or diesel power is messy, and for free flight there are better alternatives . Try a Google search for .049 scale free flight models. Might give you a better idea of power to size relation.
okay! like i was saying idk where any free flight clubs are and im 99% sure there isnt one within a 200 mile radius of me lol but ill scan the internet for some models and let you know what i come up with if you want to know

I couldnt really find anything but i was looking closer at a 400 series zero that has a 27.75" wing span says it can be used for a gas free flight or u-control flying

Yeah, I can agree with that. Originally, at the beginning of this forum I thought you meant the 17" wingspan BF-109. So, I think that would work. Especially if they give some info on putting a .049 on it and flying it Free Flight. Get your CG correct and do some glide tests, and if it glides nice, fire that baby up.

Yes, glide test it with the engine, cowl, without fuel. Why not do a build thread and show us how you're doing? Fuel proof it.

You going to do the Zero? I've always liked the Zero. Howard Hughes always thought Japan stole his design and built the Zero. It makes for a good flyer. I built a No-Cal Zero and did pretty good in local competition. Whatever you choose, all in that series could make for an interesting subject.

Build it to fly without the wheels, they're only drag and weight you don't need. You can simulate the landing gear in the "up" position on the bottom of the wing. But seriously, the real airplane had retracts, so fly it with the landing gear in the "up" position. I don't think you need them, it's never going to land with them, takeoffs are going to hand launched.

It is a pretty big price jump but i think you would be better of with a 400 series kit. Those 500 series look mighty small to me for a .049. Several guys have built the 400 series with good results, but I have never seen anyone with a 500 series plane.

lol yea! im planning on getting the zero (num. 404) because of the bigger wing span! i was about to ask, would anyone here recommend putting balsa sheets around the fuselage and wings instead of tissue? i would think that it would make it stronger and slightly heavier (which might not be bad since the engine is kinda "overpowered") any ideas? Thanks!!

Yeah, that might be a good idea, but still apply tissue over it. I've even seen guys use foam cut from meat trays glued into the rectangular spaces then sanded down to match the balsa formers, then covered with tissue. Balsa sheet is not a bad idea and you may even need the nose weight with the short nose the Zero has.

Just my opinion, better would be a dusting of silver or aluminum paint. But weren't most Zeros painted kind of grey or green? Don't look for ways to add weight. But it's your plane, you can finish it anyway you want.

Best suggestion I could give you, find tissue of the approximately the right color, use Butyrate dope to adhere and fuel proof. Not sure what tissue the kit supplies, it might even be light silkspan. In that case, I'd say, just make an all white (don't paint) Zero. http://www.aviation-history.com/mitsubishi/a6m-7a.jpg You're not flying competition Free Flight Scale, you just want a nice Scale Mitsubishi Zero powered by a .049.
