Impact Weights

[proparc]

What was the ACTUAL weights of Paul Walker's various Impacts in the years that he ACTUALLY won the Nats with it.
Thank You

I believe Paul told me his WC plane was 65 oz.

[Derek Barry]

I think that the new one(Red and White electric) was quite a bit heavier. He told me he had a hard time keeping the weight down with that power system.

Most of them were 62oz. This seem to be the ideal weight for the plane. He built one that was considerably lighter that didn't fly as well (in the 52oz range). He's also had some that were a bit heavier. But usually around 62oz give or take an ounce. The electric impact was quite a lot bigger than the usual and a bit higher aspect ratio. I think 750 square inches, and it was heavier due to lugging around almost 30oz of electric drive train.

According to his posting http://stunthanger.com/smf/index.php?topic=12044.msg106116#msg106116

the electric Impact weighs in at 69oz, flying 5.3-5.4 s laps on 70 foot lines.

No, the one that WON the WC's in 1992.

Hi Derek,

I was fortunate to be able to fly with Paul this past weekend. We had some good talks about his beautiful (take-apart) electric plane. It flew as good as any model at the contest (there was another world champion there with a fantastic flying plane too!, along with some national champs).

Paul's next Electric plane is coming out very light. He has found ways to lighten the power system and the aircraft. There will be more info on both Paul and his new plane in the next Electric column of SN. 

It was a pleasure watching Paul fly his beautiful Red/White/Blue Electric plane. It is so smooth, quiet and powerful. It just slowly drives through all the maneuvers and makes the pattern look effortless, like a beautiful dance. ..... Of course Paul's flying skill helped make it look good too!

I knew there was some catch!

[Paul Walker]

The good ones were 63 ounces +/- 1 ounce. The WC plane was approx 63 ounces.

The one mentioned at 69 ounces is an electric plane, but larger than the normal Impact.  It was made that way for the weight of the electric power system.

If you build them at 59 ounces, great. Don't add any ballast to get it to 63!!    (How's that Sparky??? Did I say the right thing???)

This was before the weight-reduction modification.  I don't know if Mr. Walker wants me to reveal it, but he had all the unallocated bits in the ESC and timer set to zero to reduce weight.

You're an evil man!

I bet he weighed it uncharged too.
