This is my latest effort.
No more takeoffs being 2 to 3 points behind!

RC Storick · « **Reply #1 on:** February 28, 2013, 06:12:46 PM »

so how far behind do you think you will be? Looks good

Paul Walker · « **Reply #2 on:** February 28, 2013, 06:26:26 PM »

I figure this will be 18 or 19 on appearance points.
I have also gone back to wing mounted gear and anticipate takeoff scores will improve also. Landing should be easier to smoke as well.
I figure 4 to 5 more points per flight than last years plane.

Time will tell.

Bob, that's really bad.

After I had Sina yours, I had to contact him. I hit a real mental road block and asked for his help. It took us nearly 2 months to get to this point, but it was worth it.

I get it. Inside joke. I haven't "seen Sina" since he moved from the Minnapolis area. Really nice guy and very talented in the graffics area. Wish he had moved the the St. louis area, I need all the help I can get! Next time you talk to himtell him hello from me.

Hi Paul,
If you were a hockey fan, and was living in Nashville, you could have borrowed from their logo and team colors, pretty wild actually. Up where you are there are the Vancuver Cannucks, but that namewouldn't make sense to a lot of people. If you were a hot rod fan and liked to do flame jobs, Calgary offers another possibilty.
I still can't believe they have an NHL hockey team in Nashville???

That's one thing I have noticed about many electrics, particularly those with backwards props - they do funny stuff at takeoff. Part of it is the fact that it's at full tilt boogie right away presumably.

That looks GREAT!!!!

Are you sure you want to go to wing gear?

I mean I use them but....you know...that doesnt mean nothing...I think you should go with the fuse gear and be sure not to rub out the clear! Then you will be good to go..........

Doug Moon · « **Reply #11 on:** February 28, 2013, 08:46:55 PM »

Paul Walker · « **Reply #14 on:** February 28, 2013, 09:37:45 PM »

The Canuk crew already weighed in on this. Not the colors of Nashville, but the name. It has Senators colors though, but not their name.
Actually, I selected the name and colors before working with Sina.

My takeoff problems I am sure is due the the flexibility in the fuse gear. Hard to hold down in it when the gear compresses, stores the energy, then releases it as the down pressure is released. The carbon wing gear has MUCH less flexibility and will not exhibit the same energy release. I used to do wing gear with no issues, but migrated to fuse gear.

Haven't put all the pieces together yet. I'll do that Friday and report back then.

Based on my original allottment, it should be around 63-64 ounces. The battery will be the major descriminator in that number.

Igor Burger · « **Reply #19 on:** March 01, 2013, 01:59:07 AM »

Lion and bear on model before start were not enough in Pazardzhik ... I see Paul decided to have some stronger animal permanently on wing for next summer

I would agree, however, Bob had some really good takeoffs during the top five last year. It was easy to watch from the sidelines...

I like your layout scheme. Did you get the idea from the Stealth bomber?

Outstanding!

Paul Walker · « **Reply #25 on:** March 01, 2013, 12:20:38 PM »

Weighed it this morning. 49 ounces without battery, arming plug, and tip weight. It will be around 64 to 65. I know of another Impact that flies at near that weight that holds its own! That plane and pilot should go to the team trials as well.

No test flights soon. Flying field still under a foot of snow. However, with a number of 50 degree days coming, it might be clear soon. I will be heading for VSC in two weeks. Once back it will be sanded and polished. Then I will test fly it.

Mark Scarborough · « **Reply #26 on:** March 01, 2013, 12:24:27 PM »

VSC this year,, of course,, well have fun,, I would love to go again this year,, Last year was quite the educational experience for me,,

Exactly. Bob was on wing gear. They don't load up spring off the ground as much as the dural style, or wire fuse gear do. PW touched on it and said it was hard to control with such a short time from standing still to full speed. If at full speed the plane is trying to fly and the pilot is trying to keep it down for a longer roll out the moment the up input is fed to the plane it hops a little off the ground giving a very noticeable lift off point.

Wing gear don't do that as much. They are much more vertical coming down to the ground and don't flex as much so the effect is way less. This happens with IC motors too but it isn't as easily noticeable when it take a bit of time to get to speed. The roll out is easier to handle and the plane lifts off smoothly.

I see/read the mind gams are beginning long before NATS time. I like the agressive look of the paint scheme. But, according to the picture, another quart of clear will be needed to bring out the shine.

Paul Walker · « **Reply #33 on:** March 01, 2013, 07:40:59 PM »

The first picture was before the clear, and the others were after a quart and some if clear applied. It needs to sit a month and then be polished.

Dan McEntee · « **Reply #34 on:** March 01, 2013, 08:03:37 PM »

I have a question about the rise or pounce on take off. It was drilled into me when I got started at contests and was asked to launch some pretty nice models, that you don't hold a model down at launch, you hold it back. One hand cupped around the leading edge with the thunb on top for the engine start, and the other hand around the opposite stab leading edge. Once the engine is started and needle set, you should just be holding the model back. In a three point stance and a positive angle of attack, it shouldn't be forcing itself down. At the pilot's command, just flex your fingers and off she goes. I have seen models bounce a bit on release, but it's usually caused by the pit man and his method of release. That, and don't have it pointing too far out of the circle.

A quart of what kind of paint? A quart???

A quart of what kind of paint? A quart??? A quart of paint weighs 28 oz. even if it gassed off 75% thats 7 ounces of weight.

Paul Walker · « **Reply #36 on:** March 01, 2013, 08:39:54 PM »

Randolph's clear. The entire clear added just under 2 ounces, and it will be less after gassing off for a month.

You must have missed the plane when painting. Weigh the paint

Alan Resinger · « **Reply #38 on:** March 01, 2013, 09:10:37 PM »

Robert,
My new Crossfire had just under 2 quarts of clear and that 2 quarts was thinned to about 40% clear and 60% thinner to total just under a gallon of liquid. Total weight added was 2.4 oz. after it gassed off. Since I buffed it out it lost another .1 oz. My total paint job added 8 oz. Of course now everything in my shop has a coating of clear paint dust on it. So yes, you do miss the model with a lot of the paint.

john e. holliday · « **Reply #43 on:** March 02, 2013, 08:11:06 AM »

Used to be a pint is a pound. So a quart is 2 pounds. What happened to make a gallon less than 8 pounds? Not counting the weight of the container.

Bob Hunt · « **Reply #44 on:** March 02, 2013, 08:54:57 AM »

Extreme evaporation, Doc! Bill Simons once weighed a ship before he applied a quart of un-thinned clear to the model. He thinned the clear and shot it all on. Then he let it dry several days and sanded and buffed the model. Th total weight gain from the clear was just over 3/4 ounce!

The new polyurethanes also "gas off," but not nearly as much as clear dope does. You use less of the polyurethane clears, and you do sand and rub them. I've found the gain in clear is about an ounce sanded and buffed. Nearly a wash with dope, but much better quality, and a much longer lasting finish. Just my opinion of course...

Paul Walker · « **Reply #46 on:** March 06, 2013, 07:56:38 PM »

Since I didn't make it clear earlier, Sina Goudarzi was the graphic designer who developed the scheme. He also did Bob Hunt's Crossfire repaint.

I simply told Sina the three colors I wanted, the fact that it needed to be aggressive, and presto I had six schemes to consider. After quite a bit of discussion, this scheme evolved.

Once done, the files were sent to Mike Haverly and the masks were cut. The red and black was done in about one week. What a joy.

Thanks Sina and Mike.

Randy Powell · « **Reply #47 on:** March 06, 2013, 08:26:15 PM »

Yea, using masks is sure a lot easier than tape. Nice work.
