Much more expensive than practical and the planes have to be lighter .

Dean,

But we already KNOW the answer to "Life, the Universe, and Everything". It's 42. But what is the QUESTION??!!

I just couldn't help myself. :D

PS, for those of you that don't get it, read "Hitchhikers Guide to the Galaxy". Don't Panic!

There are way too many design issues for us to talk about in just one forum, and when I can't really answer a question completely, I choose to keep my mouth (keyboard?) shut.
But you called me out, so here I am. I promise not to give you the answer to "Life, the Universe, and Everything" in fifty words or less.

Yia,

Some may disagree with part of this statement.
For me it's more practical to run the E.
The money I have invested in my E ship is the same as setting up a ship with a 160 DZ.

But to each his own.

The planes do have to be lighter though.

Now, keeping with the thread. Here's a design idea. I've mentioned this before somewhere. Yes the E planes need to be built lighter. Fair? Probably not IMO. Takeoff weights have to be lighter for E than they do for glow (not trying to start a discussion on this as it's already been covered). Therefore in the wind the glow plane can penetrate better. (I fly in a windy place) So flying slower with the E and being lighter isn't an advantage at times. So I have had the idea of mounting a fuel tank in my E plane and adding 16 to 20 ounces of fuel. It's gotta be legal right?
I may implement this in a future project when I get a little lighter. May even bring it to the nats.. That'll be interesting to hear what they have to say. LOL

One thing I learned attending my first Nat’s this past summer is that the rules are not always black and white (even when they are clearly written!) One must also consider the intent or spirit under which the rule was created.

Interesting proposal, but I don’t think that would fly…wrong kind of fuel for your powerplant of choice!

Who sa it neds to be fuel, you could load the plane up with a pressureized container of fluid, then, upon completion of the flight.. purge the tank. land, weigh, and be under 11 :)

just a thought.

Whats the advantage to carrying up more weight? I have always felt like a 10lb plane was easier to fly than 11, (or 11.5 and 12.5 wet weight). No matter what the wind condition. Takes less power to fly etc. Plus the lighter plane will slow much better and respond to throttle quicker than the heavier plane.

I have been patiently waiting for someone to come up with a gasser thats available and has a smooth idle, so much so that someone will take up the challenge do the R&D and carry it out; like Jason Shulman did for electric pattern.

Ive seen the ZDZ 40 in a plane, and the MVV 26 in a plane. Im really curious to see the ZDZ 40 F3A if they ever release it.

The advantage IMO is in the wind. If it isn't windy, I wouldn't want the extra weight. I find that I don't want an 10lb electric. I'd rather have it 12 lbs in the wind.
If you watch Troy Newman fly his Ys powered Pinnacle in the wind (as he fly's quite fast) he doesn't get bumped around. It cuts through the air. Not that his plane is heavy, because I doubt it is. But the slow flight of the electrics tend to get bumped around IMO.
Add a little ballast and you cut through the bumps a little better.
Of course once I go down from a 22x12 to a smaller prop I may think different. Just haven't done it yet.

I have seen people with glow that have a very very large tank and fill it completely on windy days. Landing with over a half tank still.
Same concept really.

Why not just fly faster?

Mainly because I like the performance of the 22x12 on my motor. I will be testing some other props soon though on my new ship as I may like a smaller prop better.
