[quote=tomww;1233764]Do you really not realise your ground speed and MPG are due to a stonking great tail wind?[/url]

Do you realize those MPG numbers were calculated using TAS, not GS?

If I had used GS, the -9 is over 40 MPG and the -6, with a slight tailwind is at 28.1 MPG.

One other thing I noticef, the -9 is flying at 17.6 DA and the -6 is at 16.6 DA.

Impressive numbers for both aircraft. (Even though the -9 is the better aircraft for high altitude cruising.)

Wrong. The EMS-D10 in the -6 computes MPG via groundspeed; it has no access to TAS data.

Ditch the pole vault nosewheel design and be a real man.

Put the little wheel in the back;)...I changed my mind on my build to tailwheel. Hope I like it.

Uh oh....now I did it.

Do you have great BIG oversized tires on your truck also to compensate for.....:rolleyes:

Stu,

See if you can arrange back-to-back rides in both, if you can find one of each with the same engine - prop combination.

That is the only way you can make an honest assessment of what is best for you.

You guys are great
 
Well I knew I was headed to forbidden territory with the the tailwheel comment. Serves me right.

But....mission accomplished. I managed to get Captain Avgas to chime in. Nowadays, That's a rare feat.

The reality is that either model is sufficient. I personally prefer a 45 stall speed for various reasons.

I actually drive a piece of junk rusted out Toyota Tacoma that I have to keep the drivers side window cracked open so I can open it up from the inside because both door handles are broken....but that little engine keeps on purring. Not even sure if I could put bigger tires on.

I must admit though....I'm puzzled. In your signature, you have an 8 in progress, but you are are asking about a 7 or 9? Are changing?

I think a carbon cub would be fantastic....until you have to travel a long distance..so I hear you on that one.

Do a search on here for videos of a gentleman from Seattle who recently flew his red and white 7 to Alaska. One of the best videos I've seen to date.

Especial for the 9 that is going almost but not quite as fast as the 6. :D:D:D

More so when you consider that I wasn't at full throttle on that flight.

Hindsight, wish I would have gone with a -9 Tailwheel. How about a -9 with a YIO-360-M1B with Smooth bottom cowl, maybe some big tires up front and a baby bushwheel in the back, that would be cool.
