Awesome day at Maitlands as usual. Blooded a new sloper (Well done Chris, unfortunately his "landing" occurred before he expected it, but already repaired), successfully maidened two new Zagi's, Had a spectacular mid-air, got a flying display from 3 real warbirds, saw a speedy hang glider in action, and Ken even got to climb some trees.

Awesome videos of yesterdays action. You could feel the excitement building early morning when the Whatsapp messages started,everybody was busy charging batteries and negotiating with their goverments for a day out in the slope. Flying was action packed and my sentiments go out to Ken who after spending an hour in the bush retrieving his plane came back with a backside full of thorns.
Awesome days flying and we missed those who were at Slipper....

The walk is worth it but by the time you get to your car you have forgotten about the fun and need to find other ways to make the walk fun

Who's gonna try this????
check this out........ Sloping an Heli. This is a SA guy that did some research...
Letter from Guy that slopes a heli as advice......
When I slope soar the heli, I remove the engine, canopy, 2 servos, tail
rotor, gas tank, gyro, etc. I.e., it's a really stripped down bird. Might
be better say what's there rather than what's not! Just 3 servos (collective,
2 cyclic servos), receiver, batteries, frame, head and blades, landing gear,
tail boom, and vertical stabilizer. (The latter for weathervaning
I set up the collective to go from about -7 to +12.
To get the heli started, I stand at the edge of the slope and hold it
overhead with my left hand, gripping it by the top of the frame just behind
the main shaft.
I move the transmitter collective stick all the way down. (It is essential
to have a transmitter neck strap to do this, since you only have one hand
to manipulate the transmitter controls!) Slowly at first, the blades start
to turn. They gradually pick up speed. As they go faster, the angle of
attack the blades see decreases, and at some magic moment they unstall.
Then, the blades suddenly start going REALLY fast! I then use cyclic to level
As the blades are cranking at their high speed, I move collective up.
It is easy to find the collective setting that maximizes lift; you can feel
the lift on the hand that is holding the helicopter. At this point, the
helicopter is straining hard against your hand, pulling upwards.
With your right hand on the cyclic stick, say a prayer (;-)) and release
the helicopter. It will shoot straight up maybe 30 or 40 feet. As it
does so, the blades will slow down, and reach a steady rate. At this
point, I take my left thumb off the collective entirely, and fly only
with cyclic. (I found the hard way that if the heli starts to settle it
is easy to subconsciously add in collective, and cross that threshold where
the blades will no longer keep turning. Lose head speed fast, come down
over the cliff line fast, ..., not good.)
As long as the wind hangs in there, you can stay up as long as you want.
You can use cyclic to fly back and forth along the ridge line. The
vertical stabilizer on the tail will ensure that the heli weathervanes, and
keeps going forward, nose into the direction of flight.
You can play the collective up and down a little, always making sure not
to push it too high and suddenly lose head speed. And, you can do a
"flare": pull back on the cyclic to expose more of the rotor disk to the
wind, and see the heli shoot up and somewhat back.
To land, I use cyclic to hover at altitude just behind the edge of the
cliff, and then use collective to slowly lower the heli. The goal is to
set the heli down on the ground at the edge of the cliff. But, it gets a
little dicey, because at some point you descend into the "shadow" of the
edge of the cliff and out of the wind. Expect a lot of "adventurous"
landings if you try this. But, the good news is that most crashes are
low-energy affairs and don't hurt the heli too much. Also, head balance
etc. seems much less critical doing this than flying with an engine.
Tail boom strike? No problem! Just bend that tail boom straight and
throw it off the cliff again! (The only thing the tail boom is doing is
holding the vertical stab; no tail rotor, etc.)
I think it would be really wild to try some aerobatics this way. The
ultimate would be to go inverted and slope soar back and forth along the
cliff inverted. Haven't done any of that though.
All in all, this is a lot of fun!

Ja the heli thing is fascinating but that slope... how does this guy get to work in the morning with all that mountain right there!

WE IN THE FREESTATE HAVE BEEN PREVIOUSLY DISADVANTAGED AND ARE STILL PRESENTLY DISADVANTAGED. No one can afford a slope in Bloem.
But if you drive 60km east you get to a "homeland" ThabaNchu.
2 mountains to choose from. If a north - south wind is blowing, you better get a proper 4x4 Hilux. Nice landing spot on top but it needs skills and about an hour and a halve to get from the bottom to the top.
The other one (in the vid) overlooks Botchabelo. It has a road right to the top ( very much deteriorated in the past 7 years) but the Vito felt safe going up there. It has a wonderful southern slope and a very good North western slope ( last one used) Landing however is for the brave you have a car roof, Lightning conductor or rocks and boulders to choose from as a landing spot.
Foamies, especially EPP are the only ones you would want to fly here. We did build a huge net to catch the composite and wooden models. but it takes an hour in total to rig.
We used to go there at least twice a month. Now i will get the guys "LUS" again and hopefully go there often.
Now for my first proper autoroto to do a proper landing.

Spektrum DX8 Upgrade
Spektrum DX8 Firmware update!!!
The version is 2.05. DONT UPGRADE TO THIS VERSION.
If you have a servo channel reversed, the end travel points cannot be adjusted anymore. Te servo will only travel 100% either way - no more, and no less.
They are currently busy fixing the bugs in V2.05.
