Nothing in particular. It had started a slight "rattle" sound a few weeks previously. I went through the airplane and tightened everything. It wasn't much.

After the first sequence on the second flight of the practice day in Bakersfield I heard a little more definite "rattle". I landed immediately and went all through the plane again looking for something loose. I didn't find anything.

I took off again and on the turnaround maneuver to come into the box I could hear the "clank of death". I landed immediately. Now it was idling rough and took extra trim in the throttle to keep it running.

It didn't come on all at once. It went from a slight "rattle" to a "clank" just doing the half cuban turnaround maneuver.

interesting... Jim McCall toasted his DA120 last week... the symptoms and sounds for the failed DA120 very similar to what you're describing... on a turnaround pass the engine was rattling louder and then BANG! she was done.... I think the crank went but we'll see what DA says next week.

Thanks DA!! They turned it around in 9 days including the shipping both directions.
I just wanted to mention that I was able to remove and reinstall the lower half of the cowl with the baffles still attached as long as I had the air scoop removed. That made it a simple task to remove and reinstall the cowl.

I was really looking forward to flying with a bunch of the NorCal guys that I hadn't flown with since the Bakersfield IMAC back in 2005. I went out to the field on Saturday morning to say "Hello" to everyone, then drove back home yesterday.
My DA 200 was repaired and I reinstalled it a few weeks ago. I had 5 practice flights and headed up to the Fresno IMAC contest last weekend so I could fly with the NorCal guys. I drove up on Friday and arrived at 4:00 PM. Their runway is probably a runway 11 and 29, so the sun isn't really too bad in the evening. I got in 3 practice flights at their field on Friday evening.

We had four pilots in the Advanced class. Just like the Yuma contest in April, I was leading by the value of one half of ONE maneuver after the Known rounds on Saturday. Again, it would all rest on the Unknown on Sunday morning. I think all 4 pilots got through the Unknown with no zeroes. Great stuff, guys!!

I ended up winning the Unknown round because the plane flies and snaps so true. There were six snaps in the Unknown and I hit them all.

I met another pilot, David White, and his wife Jeannie (sp?). We got a couple pictures of our planes before his next flight. David ended up 2nd place in a 7 pilot Intermediate class. He only finished behind the youngster Matt Morrell. Very smooth flying!!

They really are a great value. I hate having to maintain covering on an airplane this large, well any airplane for that matter. They are much more repairable should you have an accident then what most guys realize. They are built dead accurate, I know of no other ARF that I can say that about. Maybe 3W but their airplanes paintwork over Untracote starts looking poorly rather quick. Their honeycomb construction is not as durable and they come out weighing the same. I have owned 3 CARF airplanes and have not had to adjust wing/tail incidences on any of them. Once you have one for a few years and it has some bumps and bruises simply do a little body work and spray some new life on it. Basically a new airplane again as the composite construction just does not wear out. Mine was tossed into a dumpster by a friend of a friend. My friend just happen to catch it in time and showed up at my door and asked if I was willing to give him 300.00 for it so the original owner could at least get his shipping charges on his new airplane covered. I handed him cash on the spot. It's a bit of a "FrankenExtra", the gear is off an Aeroworks kit and is now mounted externally. The wheel pants are Carden and I added some gear cuffs that I have molds for. The only mods I made that "might" affect flight performance was to trim off 3/8" from the rudder and elevator TE. This leaves about. 1/4" thick blunt TE that theoretically will help the model track and get rid of the rudder wag that some guys were experiencing with the old 3M.

I spent a cool weekend in San Diego last weekend flying the Miramar IMAC contest.

I hadn't flown since the Fresno contest the first week of June. My field chose to implement a 400 foot ceiling while they get permission from a local airport following the FAA clarifications on the UAS regulations.

I joined another club the weekend before this contest and got in 2 practice flights just to make sure the clunk line wasn't stiff.

There were four pilots in the Advanced class. At the end of the day Saturday I was leading by 7 points (out of 3,000 possible). Me and another pilot had both won 2 Known rounds.

I didn't get any zeroes in the Unknown Sunday morning but it was sloppy. The other pilot won the Unknown round and the contest. He was the better pilot. And he was flying a 9 year old CARF-Models 3.0m Extra 260.

I was very happy to place 2nd in this group of 4 pilots. We had a great weekend of close competition. That's always a lot of fun.

We had a very windy contest last weekend at the Tucson Shootout field (TIMPA). I hadn't flown since the Miramar contest so I got my usual couple flights the weekend before the contest to make sure everything was running.

The flying part of this contest wasn't a whole lot of fun. Flying in a 15 - 20 mph crosswind for 2 days is really a matter of survival. I had this guying saying a little prayer for safe flights at the beginning of the 2nd day.

Catching up with everyone and talking about planes for 2 days was the fun part. The highlight of the contest for me was having Mike Marcellin (Tucson Shootout CD for many years) flying in a contest. He hadn't flown in a decade so this was a real special deal. You could see the huge smile on his face all weekend.

We had a 3 pilot Advanced class and I won (survived) the contest.

The large CARF airframes sure made it look easy carving a path through the wind! Congrats on your win this last weekend.

If you haven't been to the Tucson Shootout field (TIMPA), it's fairly common to land out in the desert coming straight into the wind. It's always a little dicey because you don't know what gopher hole you might be unlucky enough to hit.

My Saturday afternoon landing rolled very rudely into a rut. The tail went up and I was lucky it was going slow enough it didn't tip over. The landing gear plate stayed secure. Both wheel pants were damaged.

I cleaned them up, put the broken part as close to the original spot as possible, and used a little thick CA and some 2 ounce fiberglass cloth on the inside to secure it.

I used a Dremel drum sander to enlarge the wheel opening and make the repaired area a little smaller. I finished it off with a little black Sharpie. It's on the inside bottom of the wheel pant so the area will never be seen.

At the Tucson contest I was watching another pilot fly his Extra 330SC with the same engine/canister setup and really liked how quiet it was. He was running the Falcon 30 x 14 propeller. I asked him about it. He said it didn't have the same thrust as the Mejzlik 30 x 13 but thought it has slightly better downline braking. I'm running my full throttle ATV at 85% so I'm not worried about losing a little thrust.

Our next contest is in Las Vegas at the TOC field. It is very close to an apartment complex and I was interested in having my plane quieter. I ordered a Falcon 30 x 14 to try it.

The drilled Mejzlik 30 x 13 EvoLF weighs 7.6 ounces.

I tried it yesterday. It wasn't any quieter.

Come to find out that pilot only uses a little over half throttle on his uplines. Way better throttle management than me. I guess the placement of that left stick has a big impact on the noise.
