Volantex Super Cub & Taranis (10 min 25 sec)

A little bit of morning video + I went out again in the afternoon .

Changes in the afternoon =
1) 44mm Wheels
2) A little lead in the tail

Seemed to fly and land a little better ..
Wheels are still too small . flips on landing ..
Rolls better on the 44s but still flips .

I've prep a tail hub and grips assembly for Gaui X3 to replace the head, feathering shaft, and blade grips with it. The balls I took from the metal grips for k110/k120 and did a little filing to the part that's inserted into the grips. So, the k110 dog bones are a perfect fit and I've got to sleeve the 2.5mm shaft for a 3mm fit. It have thrust bearings in the grip and might need a washer to hold the blades. I few members have done this to their k130 and I'm also preparing one for my K130.

So I got myself a Yak from Pilot. I love how it flys but the quality not so much. I have had to rebuild the gear box about 5 times. I will admit that one rebuild was do to a hard landing but the rest have been glue joints from the factory giving way. I swear they must use chewing gum.

I also got myself a Krill Extra 330, 31% with a GP76. I LOVE this thing. Its a beast.

And I am working on a Balsa USA Nieuport 28 1/4 scale. Coming along quite nicely.

Stuffed up the cam again !
I charged the battery last night , and it was another instance where the cam did not turn off after pulling the USB cable ( Which it should do )
So this morning the battery was flat . ( I think I need to check the battery every time I pick this cam up now )

PNP > Yes the Super Cub is plug an play now ! No more stability .

How did it fly ?

It was nose heavy , I am going to have to re-check the CG . The Cub has been nose heavy from day one .
I went up and the Cub was hunting the ground , so I landed and flipped the CUB . ( Those wheels are too small )

I moved the battery further back .. Went up and now it flew very close to the money .
Flying relatively fast ( more than 50% throttle ) and the cub does cut a fine line . Butt's !!! , I like to fly slow !
Dropping the throttle to 40% or maybe 35% the cub began to squirm a little . Did a little jimmy , with the wings just twitching forward one way then the other . Maybe like a car driving on ice . Kind of made me think I was close to stall . And to be honest it was not that slow , I have other models ( Lighter obviously ) that fly much slower .
Rolls > Not enough aileron ! I jammed in about 75% throttle and the roll was so slow I could only complete about 75% of the roll and then I had to pull out ! ( Of the roll ) It was a nerve racking roll cos it was so slow .

Landings , I jammed it into the ground 3 times because !
The cub seems to...Continue Reading

This is a special build, for it is a tribute to my dad who passed in 2015. Within the first couple of years after his death, I restored his two Zagi 400x wings to flying order and find it a treat to channel his flying through them These nearly 20 year old wings endured my antics until summer of 2019, when the patriotic red-white-blue one crashed itself in a near vertical nose dive, after the ESC/BEC shut off during a high speed pass, through mature corn stalks onto the dry clay soil. The right half of the foam wing shattered under the tape finish, the center plastic battery holder fractured and hinged forward, and the twin fins sheared away.

All this damage could be repaired, of course, but not without loosing the original finish work from dad. Which is annoying to me. Instead, his Zagi 400x RWB wing is presently in retirement, and my search for a similar wing yet assembled using modern design techniques is finished. Among the abundance of prefabricated, and kit, wing designs that I researched, the models from Crash Test Hobby stand out. Cut from EPP rubberized foam, in a one density for the wing, and a heavier density for the control surfaces, I was drawn to their use of string (shock cord) and 3 mil laminate reinforcements. Plus the RC gear is embedded into the foam for protection, streamlining, and simplicity. All new technique that peaked my interest.

From the abundant choice of wing sizes and shapes from CTH, I selected the Rebel S14 because of its...Continue Reading

Halloa people,

I am in the midst of publishing a (LONG :P) how-to-build series and one of it's video is partly about the video-transmitter choice.. Maybe this is helpfull to you if you're new to FPV and are unsure what camera would work out for You...
Also in this video however I explain how to install the VTX & configure it in Betaflight

The VTX I'll end up using: Rush Tank Ultimate PLUS - 800mW

DustOff #4 - Volantex Super Cub V765 - Great Flying Super Cub with Plenty of Power ;-)

Here is a link to the Video:

I don't have a lot of time with this Plane but I'm getting more comfortable with it every time I take it out.
I'm a bit rusty on the landings as it's been a while since I've flown this Super Cub.
This Plane is fairly Aerobatic and has plenty of power to pull through large loops ;-)
Let's get it in the Air!

Whenever spotting and or submerged in fpv, I always try to find the best time pieces to time my flights and or have a built in alarm to let me know when I should be landing; just in case there is some malfunction with a buzzer or telemetry data... (which is rare or never but just in case )

I've been wanting to get a jet for years now but didn't want to go with one of those rtf foam planes that most folks start with.

I had read a lot about my options and found out the F-16 was a good first jet for a lot of folks back in the day. So when I found this one at the Perry swap meet last week I couldn't pass it up. I bought it as a bare airframe, and I'm starting the search for an edf motor/fan. I'm not sure if I want to go with an original "byrofan" setup or go with some carbon fiber setup from this century.

It's been worked on and appears to have been reinforced with cloth and has servos mounted in the wing. It also has a flying stab configuration, and a fixed rudder. It's been sitting on the intake and fins for a while now and has a few cracks that are mostly minor.

It seems I never get a plane fully finished and detailed until after I've flown it for a while, so I'm not going to worry about its appearance for now. I'm really looking forward to getting it flying and finding out about all that hoopla with jets...

So, the "Engine Sniper" moves stealthily through the tall grass of internet anonymity, eyeing his Ebay target in the manner of a mountain lion stalking a fawn, with his PayPal locked and loaded as the time ticks down.

Cold-blooded, he has little compassion for his fellow model airplane nerds that he KNOWS are lusting after the same treasure...for THEY are JUST as cold and unfeeling...and deserve no mercy.

In a low whisper that barely crosses the darkened room, the Engine Sniper's utterance is more breath than spoken word,
"Not today, my friends...not today..."

With a few moments to spare, he allows himself to recall his victory of the previous evening, when he snapped an Ohlssen & Rice .049 from the midst of a group of week-long competing bidders...
With a sum so massive, it was akin to aiming a cannon at a hamster, he'd waited 'till the last 5 seconds to unleash the Fury of "Auto Bid". He then punched the "B" button.

His fellow nerd bidders were scattered like so many hyenas forsaking fresh carrion to a pride of hungry lions.

The surge of electronic money swamped and exhausted all other efforts, and then shut itself down after claiming it's prize with only a few dollars above the previously highest bidder. Before the dust had settled, it's seller had received payment, and the Engine Sniper once again disappeared into the internet marsh.

Now, the target is a fairly nice Anderson Royal Spitfire 065. From the 1950'...Continue Reading

namely, the bms-661dmg+hs

i provided feedback in this thread, been using these in ground vehicles for years, no servo saver and some pretty decent bashing. no failures to speak of other than broke the ears off one, but that was a full speed hit into a stationary object, hit hard enough to rip the a-arm off and break the center out of the wheel. that servo still works fine, just the case has no ears for mounting.

well yesterday another one failed. car started steering sluggish and then complete failure. the servo arm locked in place. i took it apart to find motor and probably board too was burned. gearset was fine but motor completely locked.
i did notice what looked like corrosion on the motor can, probably from water getting around the oring seals(not very good seals i noticed).

either way, the servo went for many hours before giving up. who knows how much longer it would last if kept dry. I have 3 others in service so will keep evaluating.
also will take the unbroken case from this dead one and fix the other, put it back in service.
