so Crist on you build log. How much does the log weigh? I could not resist.

As us fans of Crist's Build Logs can attest, his logs are definitiely not hollow logs. They are packed with great information, new ideas and LOTZ of pictures. While the resulting models are usually light, the logs are definitely HEAVY..!

He flies aginst me all season long so I like it when he builds logs.

Progress is coming along. I cut down a 13x5.5WEP to 12 inches and balanced and mounted the prop.

When sanding the taper into the left flap, I must of had the flap sitting on one of the 1/32 plywood pieces that I glue to the 3/8 rod to keep it from rolling and ended up with a off center hinge line near the tip. So I made a new flap and the second one is good. Ready to cover both the elevators and the flaps.

I also dyed, using RIT dye, the battery straps from yellow to black. I get my straps from Tanic Packs and they are the 10" size.

Just about done. I have to clean it up a little , then seal the hingelines. A coat of wax on the Monokote and it'll be ready for the circle.

The weight came out to 51 3/4 oz with 1 oz of tip weight. Balances at 19%.

Looking forward to the ICE-O-LATED contest in St. Louis in a 2 weeks.

That looks very nice Crist, anxious to get the flight report.

Dan Bregar · « **Reply #155 on:** February 11, 2013, 03:57:01 PM »

Super nice ! Hey Crist, how about a pic or 2 of how you go about sealing the hinge lines ?

Jeff Traxler · « **Reply #156 on:** February 12, 2013, 05:53:51 PM »

Very,Very nice Crist,I like the shot with the plans in the backround.Maybe we can get a shot of a beautiful Muncie sunset in the backround later this summer

Well Done!!!! Trax

Dan,
Here are a few pics of how I seal the hinge line. I use 3M Multi Task tape. I clean the hinge line then I roll out the tape to the proper length. Then I trim off the corners by 1/8 inch. Then I place the tape on the elevator and then rub it down while holding it off the stabilizer. I then use a craft stick to get the tape down into the hinge slot. Then I roll the tape over the stab TE. rubbing it down as I go.

All done!

You left gaps in the tape at the hinges.

I never tape over the hinge barrels.

I flew the Thundervolt P today for the first time. I flew out 8 batteries. The first was 5 1 minute trim flights. The second was 3 1 1/2 minute trim flights. The next 3 were full patterns. The 6th was 2 2 1/2 minute trim flights and the last 2 were full patterns.
The plane is flying very well right now. I'll just concentrate on putting some more full patterns on it. Maybe a lead out change here and there but that would be about it.

I'm using about 1850 to 1900mah for the full flights with 5.25 second laps. I'll slow it down to about 5.3 to 5.4 second laps. It has plenty of line tension. I'm launching at 9625 rpm and my on time is 5 minutes and 15 seconds. I'll increase the on time to 5 minutes and 30 seconds next time out. I'l using a APCE 13 x 5.5 WEP cut down to 12 inches and my lines are .015 and 63 feet eye to eye long. All-in-all a very good day of flying. A very comfortable airplane to fly.

Dan Bregar · « **Reply #165 on:** April 20, 2013, 07:01:44 PM »

Thanks for the report Crist. Sounds good. Can only get better.

Dennis Adamisin · « **Reply #166 on:** April 20, 2013, 07:38:32 PM »

CONGRATS on a great first day! I like that you are already at the point where you can just start cranking in some patterns.

We had more snow yesterday with wind & cold today. The flying season is off to a very slow start!

Crist Rigotti · « **Reply #167 on:** April 20, 2013, 08:49:35 PM »

Dennis, We had some snow yesterday. Today was a mostly sunny day with temps around 45 and light winds. The last 2 patterns were high quality ones too!

john e. holliday · « **Reply #168 on:** April 21, 2013, 08:30:53 AM »

Great news Crist. Now go show the judges how the pattern is supposed to look.

John Christensen · « **Reply #169 on:** April 22, 2013, 11:39:32 AM »

Are you going to be flying that at Polk City? We need a break at least to see if the fuel is still good.

Yes, that's my plan at least. See you there.

Bob,
I use 3M SJ4570 Dual Lock to hold the timer to the ESC. It sure beats velcro. There is no "rocking" with Dual Lock. Here is a link:

Crist, thanks for steering us toward this 3M product. I just bought some and tried it and it is awesome. When you put the two parts together, they are locked, no movement at all, just like you stated. I can think of a lot of uses for this stuff, even outside of our toy airplane world. Thanks.

Crist Rigotti · « **Reply #172 on:** August 03, 2013, 07:06:43 AM »

You're welcome. I use it around the house too! Velcro nevermore.

Just an update!

The Thundervolt P met its demise Sunday at the Pewaukee contest. It was a bit windy and on the second flight in the Overhead Eight, the wind shifted nearly 90 degrees and came off the tree line that was close to the circle. This cause a lot of turbulence at the top of the circle and the next thing I knew, I'm looking at the top of the airplane with the nose pointing slightly down and zero line tension. It was over a second or 2 later.

I was using my $25 Zippy Compact 5S 2450 35C batteries and this one got damaged. Sure beats killing a $100 battery! The Cobra 2826/12 survived with a shaft and bearing change. I salvaged the stab, elevators, flaps, and landing gear to be used on the next one.

It was a very good flying airplane that presented very well.

Hate to hear this ... Crist, you will just have to build another one.

Dan Bregar · « **Reply #175 on:** June 22, 2014, 01:46:36 PM »

Crist

Very sorry to hear about your loss. Rotten bad luck !

On the positive side, I'll bet your replacement will be better. We can all hope to benefit from your nest new build thread.

Dan,
Thanks. It'll be after we get settled in Texas, but stay tuned! It will be better, that's for sure.
