Very happy to report my smoke lasted over 7 MINUTES (20oz of oil) because I changed muffler and used a Atomizing smoke oil injection nozzle from 'Crankcase'

Go to https://www.flyinggiants.com/forums/...d.php?t=196895 for a thread of his method of SPRAYING oil into the muffler as opposed to POURING oil into the muffler!

No chance yet to fly one of them, but I now have two "new" models for relatively little time, effort and money.

The rebuilt Flyzone SkyFly 2 is ready to rock and roll! Weather, repaving of the club's runway and a major two-week tennis tournament which put the kibosh on an alternate field all came together to keep me grounded, but I hope to take it up on Sunday...if it doesn't rain. The very stiff control surfaces may have led to the demise of the original servos. No problem! I had two nearly new 9g analogs which not only fit, the control arms had the same splines. Hinging the elevator and rudder of the new tail section with CA hinges was easy enough to do and it stands ready for its maiden flight. I even found the original nose wheel in the parts stash. I thought I'd lost it.

Also reborn is a Rotor Concept HPQ1, better known as the LotusRC T380. It was my first big quad, I paid way too much for it, it's been a money pit since then, it's been sitting idle since goodness knows when and that same company has the gall to sell it on Amazon for 400 bucks as I write.

That love/hate relationship really began when the motor driving FETs fell off of the FC like so many rotten teeth. I won't bore you all with details, but it eventually wound up with a new FC from Multirotor Mania and ESCs from Armattan. The motor shafts kept pulling out of the endbells whenever I went to tighten the props, so I paid good money (waaay more than I wanted to spend) to have them pressed back in and secured.

The end result? Quite satisfactory! The PID settings needed attention, especially the proportional since it was constantly over-correcting in hover. Really twitchy. After some tweaks via Cleanflight, it's nearly perfect. The really nice thing is that I now have two models which had some money sunken into them placed back in service.

Pictures to follow.

***TBS Caipi2 just arrived! Pre-orders will begin shipping right away!***

Hey folks, its been awhile but I wanted to let everyone know that we have some crossfire nano rx's still available. I see everyone is out of stock everywhere so if your in need, hit us up as we should be good for a bit longer till our restock order arrives. This is the non-SE version meaning it only comes with the standard rx antenna, not the immortal t. We should have our nano se back soon.

after an hour and a half flight time (and a few crashes )indoors and out ,mostly fpv the x130 is holding up well and so far probably my favourite quad yet (only had a couple)
very similar to the x100 but so much better feel to it, hopefully last longer than 5 days !
changed the camera for one I had (for PAL and slightly better under low light
would definitely recommend one

There will be a new foamie released by RA Cores at the Toledo show this year. It's our interpretation of an Extra which we had FastAlJr Mostek help tune for us. It's not on the website yet (release is April 6th at the Toledo Show) but here is a YouTube video of it flying 3/18/2018 in the Dome at Watervliet NY. Pricing will be the same as our Yak55 kit and it uses the same completer. Reports are it is more agile than the Yak55 so it's a good next step in your aerobatic development. Color combinations available will be Green/Purple as in the video, Orange/Medium Blue and Red/(White)/Dark Blue

This is the Second Flight with my Freewing Lippisch P.15 64mm EDF Jet. It shows off the hand launch MUCH better than the Maiden. My GF recorded both launches for me:

Dialing in Spoileron Elevator in flight with iX12

This is a method to adjust the elevator in flight when spoilerons are engaged, usually to obtain a level flight path.

Spoilerons - Ailerons go up(plane drops), elevators go up(raises plane back up)

Turn your plane and iX12 on. This assumes your control surface trims are already be set to neutral. Note here the Elevator is trimmed for level flight at -7.

Go to the Model Adjust-> Flap System screen

Pick a switch to activate the Spoilerons
Leave values for Position 0: both at zero. (Spoilerons off)
For Position 1, enter a negative value so the ailerons go up. I used -25% for this example. A greater negative number will increase the stopping power. But remember too much could cause a tip stall from going too slow.
Put approximately 1/2 of the Flap setting in Elev for Position 1. It's just a starting point. Scroll to the bottom and enter a value for speed(not shown). I used .20s

Go to Model Adjust-> Mixing and create a mix as follows:

P-Mix 1 RT>ELE : Switch D, Rate -100,+100,0% offset
Pushing the R Trim switch will move the elevator with this mix active. And will only be active with the spoilerons on.

Fly your plane and activate the spoilerons at a safe height. Adjust the R Trim elevator so that the plane flies level. Turn the spoilerons off. Fly to a landing approach and turn the spoilerons on and land the plane.

Now you want to transfer the -48 R Trim(spoilerons on) setting to the...Continue Reading

I finally maidened my second-hand E-flite Ultimate2 biplane!

It is a 2200-lipo-size Pitts Ultimate 3D foamy. Fun-scale of course.
Nice big plane (for me) with a fun 1300kv BL10 motor. 3S power system. With the stock 12x4 prop it sounds cool

I had removed the nose cone (it's crappy and unbalanced) so, naturally, it flew rather tail-heavy. Moreso than i had imagined it would...

Add gusty wind--and i crashed trying to land. It stalled. It either wanted to point UP or DOWN lol... my fault.
I know i should have added weight to the front. Maybe 5 quarters under the battery hatch cover...

It is in good shape. I just bent landing gear, afaik. I will look at it closer later

My favorite thing about it--& i have yet to fly in 3D Mode btw, is its SIZE & forgiving nature

It feels like a dang AIRSHIP compared to my other planes. It can fly slowly, too, with its biplane-ish drag & 4" pitch prop.
The foam construction means it bounces instead of cracks like a balsa model.

If it were balsa i would have not taken any chances; gusty wind & improper balance does not mix on a nice balsa airplane maiden.

I may post the maiden video later on.

I do plan to get my balsa Easy Sport airplane flying this summer with a nice Saito 4-stroke glow mill. Ideal balsa setup, imo...

On another note, the Main Gears arrived for my little Blade 130S helicopter. That thing is fun! I crashed it a week ago so hopefully will be flying soon.

I am eyeing the...Continue Reading
