Should I face the engine forwards or backwards?

I'd say backward because you can access to the spark plug easier. Now I've done both and they fly the same, but backward is the way I'd go.

backwards, the engine is more exposed to the air flow with, I think it's better to keep it cool and you avoid the spark plug to be near to electronic equipments

I ONLY run it forwards

you can put the fuel tank in the rear where its visible and it gives the model a very slightly nose down CG. If you're a sport flyer you'll like that. It also gives the model a more balanced look with the long mufflers mounted.

you WILL have to trim the canopy slightly more however the templates included in the manual make that easy.

forget about electronics issues. If you're running the 2.4 systems you won't see anything.

I run backwards as well
CG wise my model is slightly nose heavy as it is.
I got a 16oz tank up front which gives me at least 15 minutes of flight with some reserve, so no worries about seeing the tank if you set a timer.
I like the spark plug in the back for easy access.
I like the less cutting of the canopy with this setup.

Its a personal choice, do what works for you as you'll find folks who like both configs for their own reasons.

For me, same as rbort

I think about the hereafter. I go somewhere to get something, then wonder what I'm here after ?

I fly with engine facing forewards so that the tank is right on the cg. Also good for checking gas levels inflight when skeptical

I've had one crash because I ran out of fuel while inverted (my engine faces rearward). The option to see the fuel tank sounds pretty nice.
Life is certainly full of choices!!!

You could always setup the timer function on your radio and eliminate that from happening also.

Ok you sold me on backwards. Now is it gas tank in the frame or hanging from the front?

Check out my gallery
You will see detailed photos of my Spectra under the hood.

A dubro 16oz tank does the trick, as the stock one is too small designed for 3D performance by keeping the model lighter.

CNCjunkie,

That is the neatest arrangement I have ever seen. You should put that Speccy on top of the TV to stare at during the ad breaks.

125-120 is pictured and can be found at HeliProz (Spectra-G engraving)

Also available with no engraving 125-124 and MinAir engraving 125-122. I don't see the last one listed on the site.
