Compared to the price of say an OS 4 stroke it's not really that much more expensive... Compared to other Saitos it is a bit much , but considering how cheap it is to operate and the ease of operating a gas engine, I can see that it will still be an attractive option.

And of course there is at least $40 worth of "fiddle factor".
Don't we love to play with new toys?
Never had such a small gasser before, my last was a Quadra 50 on a 1/3 scale Pup. Now there's a combo that will teach you to fly on the wing.

I had no idea!
I installed a 4 oz tank since that is the biggest that will fit in the Taube and hoped I'd get 10 or 12 minutes of flying time out of it. But we fill it once and run the engine 4 or 5 times at 10 minutes a run! (we're still breaking it in)

as for fuel costs, this engine should pay for it's self after a good long flying season. (12 gallons)

I think the Evolution is the only one I would try on a .40 size plane.

But as EJ said there ARE planes that "need" that Saito.
How many .40 size airframes end up W/lead in the nose anyway? Besides, the reduced fuel load required will make up the added weight of the engine.

The only .40 size aircraft I ever owned ended up W/a Saito FA91 on the nose.

I took the assembled airframe to the LHS & placed engines in the nose to check CG. The FA91 balanced the plane perfectly.

If I have to add weight to the nose of the airplane it will be reciprocating mass, not lead.

And let us not forget the added flexibility.
you can take it out and put it in a plane designed for a bigger engine later on.

My Smith miniplane (sig for .40) had an OS 90FS and flew for years (had to move the firewall back 2 3/4"), the engine wound up in a Topflight P40 with rotating retracts. (Heavy in 1990) designed for a .60. Then in a 56" span SE5a.

And you can always throttle back.

Thats a half pound difference.
Forgive me for replying to an older post, but nobody's posting.
(must be the good flying weather)
When I put the FG11 on the Taube, the flying weight stayed within two to four ounces of when she used an OS 40 FS because I was able to remove a large chunk of lead (~4 oz. didn't have a nice scale back then) from the firewall and I used a life battery for the ignition and rx.

You have to go with the older designs like the Sig Smith miniplane, the Dreamer, the Super Sportster, the Flying Quaker and most of the old timers of 80 inches would all do well, The Sig cub is a little weak but the Goldberg Cub would be good. There's a good chance mine might end up on one of these when the Taube gives out.

If fuel gets real steep and petrol power discovers a 1 oz ignition system, you might be buying glow plugs from ebay like we used to buy spark plugs for the Bantams.

Anyway, if you want to see a 63 inch Taube that's just under 6 lbs. fly with the FG11 (and drop whistling bombs) ...
