Does anyone know of a resource that compares the running times of the various .49 engines? i.e. Gee Bee, Cox Black Widow, Norvel...

Thanks

JZ,

The engines you are talking about are not .49s, like the MVVS 8.0cc, but .049 cubic inch displacement; 1/2A.

The Babe Bee should get about 3-4 minutes on its integral tank.
The Texaco, or Black Widow get about 7-8 minutes on their larger tanks.
There were also various tanks on the Testor's, McCoy's, Etc..

The Norvel website lists somewhere in the spec section, about consumption/hr. I think. They also claim that their revlite cyl/piston process increases fuel economy.

Thanks DarZeelon and ZB50,

I realized I missed a decimal point after I posted it. I am planning to convert a Guillow's Sopwith Camel to RC. I am really trying to figure out whether or not to go Electric or Glow. I want to get longer flight times than most electric's do. I haven't even started to build it yet. Just doing my homework. I saw a thread where someone also converted one I think he used a 2oz tank and a .15 engine. That seemed like overkill to me.

Thanks again,

JZ

Hi!
I would definitely go electric with this airplane.
With modern equipment like 3g-10g servos, micro receivers and lithium jon batteries it might be possible to fly this ship.
Flight times around 40 minutes is common nowadays with lithium cells.
But built it light...Thats very important!
