I got to maiden Jack W’s new Eflite Extra 300 at WPMPA after a club meeting. The 300 is popular with at least 3 other club members having them. I know that some aluminum motor mounts have caused vibration and have failed leading to replacement. The music wire landing gear can get bent and I have retrofitted the 300 with a Dubro 40-60 nylon gear legs. This gear does not break or bend and can be screwed or bolted further forward to reduce nose over damage while moving on the surface.

Jack wanted to preserve the nice fragile stock prop from such nose over damage so replaced it with an APC plastic 13/6.5 prop. On run up on a 4S she caused severe vibration. The factory spinner was removed and this helpedbut the prop was removed and rebalanced. This still caused vibration. Luckily Manny came to Jacks aid with a brand new 13/4 APC still in the package. The bore was reamed out enough to clear the shaft adapter and the largest plastic ring was pressed into place. This took away all vibration however when the nice looking plastic backplate and spinner was added the vibration returned. So the maiden was completed with out the spinner and backplate. Jack’s Wattmeter measured 45 A , 670 W on a 3600 4S Venom and 31 A 334 W on a Venom 3200 3 S.

Takeoff was done with Self Level Off and about 8 clicks of up elevator was required for hands off flight at mid (59%) throttle. Self Level was turned on with the DX9 B0/B1 switch and max pitch and bank angles were verified at + 85...Continue Reading

Yep Les Amis,
Une CHIMERE bien Réelle ! lol . Comme vous allez le constater, ce test du CHIMERA4 LR de chez iFlight a été laborieux !

Avec une bonne lipo entre 850 et 1000mAh en 4S, on aura une bonne autonomie d'environ 8 à 12mn en vol tranquille, et avec un 650 ou 750mAh, environs 6 à 7mn de freestyle, sans problèmes. Un châssis résistant et un bon équipement électronique, je ne peux que valider ce Chiméra 4 ! Bon Film et merci à tous pour votre soutien .

NOTATAZ : 18.5/20 Je valide !!!

Les + : Costaud, Autonomie correcte, Tarif intéressant, Accessoires fournis, Bien réglé sortie de boite, Polyvalent LR et Freestyle, Bien équipé.

The free flight models use a de thermalizer system to stop the model from flying away. I wanted to do the same with the Elf and came up with a system that uses the flying stab to stop forward motion and bring the Elf vertically down. I programmed the elevator rate switch C2 to give full up that stalls the model but keeps the model level as it descends. If I release full up elevator the mode resumes flying. The Elf has to slow down gradually before applying full up elevator to get the correct level attitude before the descent starts. My low rate C0 switch postion is programmed for the Launch mode. I have elevator trim set for a high speed throw with about a 80 degree climb angle. At top of climb I can keep her in Launch mode for aerobatics or move the switch to C1 for Cruise Mode with a little more up elevator, or go into Thermal Mode C2 with more up elevator. I have the rates adjusted so that full up stick gives me the correct elevator angle for a vertical fuselage level descent. The Expo is adjusted so that normal elevator travel is available but full stick gives me full up elevator.

In flight adjustment is required to find the correct angle. An incorrect elevator angle will cause a porpoise descent or stall repetition. To prevent a nose down crash release full up elevator to recovery from the stall/crash manuever. Your CG will have an effect on the angle. My CG is slightly forward (2.9 inches) from what Vladimir’s 2.9-3.3 inch range....Continue Reading

After the 6 year old 250 mah 1S battery failure the crash broke the phenolic rudder horn and nylon stab fixture. I used thin CA and accelerator to re secure the nylon to CF boom bond. For the rudder horn I replaced it with aluminum that is bent 90 degrees for a stronger bond to the fiberglass rudder skin. I measured the music wire diameter and used some spare wire to drill a hole in the aluminum for a no slop fit. To fill the void around the rudder slot I used brown Gorilla Glue to expand and fill in the void. I have about 20 throws with no cracking or damage to the repair areas.

I bought my Elf from Kennedy Composites in Jan 2014 and have about 35 hours indicated on my DX9 transmitter. She has an AR400 with out the case and Dymond D47 servos for elevator and rudder. I purchased the Shread-RC 240 mah 1S voltage booster/charger.

Last week on the 5th or 6th throw she lost power to the receiver and Elf impacted the soft ground hard enough to break the CA glue bond for the plastic stab fixture. I checked battery voltage and with 2 beeps this figures out to 3.5 + .2+= 3.7. However after cycling the rudder for about 20 seconds the red power LED extinguished. So with 6 years of use I figured it was time for some preventative maintenance.

I emailed [email protected] but with no response I purchased a 300 1S lipo from Racedayquads.com . The Shread-RC 250 battery weighs 6 gm and the RDQ 300 weighs 8 gm. It is longer than the 250 but fits on the boom between the servo and the boom nose. I cut the red and black wires and soldered them together then taped the battery and booster to the boom to locate the charging prongs and canopy opening. After finding the correct position I used Shoe Goo to secure the battery and booster to the boom. I recently got about 20 throws at the park with 10-12 winds and found no change in handling or CG.

I had a mischief of a time unfolding the canopy for the Jetstream......I finally modeled the thing using 3D faces and unfolded each face using point-to-point projection.....I test cut the canopy out of heavy card stock, just to make sure

The maiden was a little hairy. I slowed it down a little, reduced the FC gain, and tuned the radio. Very different flight the 2nd time:

Our beloved RGB has died and Trump wants to replace her before the election. Trump picks his A-lister choice – the GOP wants to rush it through, the Dem’s fight it but it gets pushed thru the confirmation hearings, in this dream, the choice refuses the post. Time runs out, the horn blows and it’s too late game over. The next President picks the judges. RIP RBG

In another dream
New game show idea called “WHO WANTS TO BE AMERICA’S NEXT PRESIDENT?” Hosted by Alex Trebec with game show podiums, buzzers and insta-fact checking with automated scores revealing points deducted for each false fact or lie.
Final Round is called the ‘dunk tank round’. Contestants sit above a water tank filled from our very own Flint, Michigan and once the point level goes negative, so splashes the liar.

Episode 4 an homage to Dr. Strangelove (all black and white) “Gentlemen you can’t fight in here, this is the war room
Or “Nightmare on Pennsylvania Avenue” where we return to the Dunk tank and the contestants have both been exposed to the waters of Flint. And in keeping with DJT’s previous and unseemly association with the Miss America pageant – Trump and Biden have to do a swim suit competition.

Plus the snarkiest of Republicans and Democrats make up a panel of 3 each to provide commentary on the competition. It will not be pretty, well some of them are pretty, the others are pretty awful.
Mitch McConnell VS Alexandria Ocasio-Cortez
Lindsay Graham VS Nancy Pelosi
Rush Limbaugh VS Rachel Maddow

Before all this happens Trumpy is asleep and dreaming he shows up for the debate and he’s greeted like at a Trump rally. The scene looks like it’s staked and pitched in his favor. He has the best answers Man, Woman, Television….

So he wins the debate 100 to Zero. Then he wakes up and goes to the game show. At that point the nightmare begins
Evil laughter…bwwhahhh-ha-ha-ha
