These guys really have fun and its a non competetive gathering , funny I was struck by a "younger guy" who was teaching his young daughter to fly on one of these old planes with a buddy box, these designs probably even predated the Dad as well.
Nice to see our aero modelling "heritage" being passed on.
A growing trend is to fit these rudder / elevator planes with modern electric motors for fuss free silent flying, a real mix of old and new technology.
I love the traditional construction not an ARF or piece of composite construction anywhere to be seen .
Without a doubt my favourite was this "Playboy " design with the eliptical wings and pylon mounted wing.
Some of the others like the Quacker Flash (below)is also a name I can remember my dad talking about in his modeling days .
The powerhouse shown below is the one I am currently contemplating building as I have the plans and at this stage three motor options 4-stroke , diesel and electric.....maybe the Dark Side has really got me, as the electric option is top of the list.
This is a blog about gliding so I will also show a picture of Ken's Ka6e being aero towed which these guys now have as their favourite method of launching gliders.
The Jomac gliding group is really dedicated and can certainly teach us all a thing about this technique. They tow lightish gliders up to about 4 mtrs with their tug..now if only they had a BIG REALLY BIG TUG.
Cheers for now
and you thought I only flew gliders .

A group of us headed to Volksrust over the long weekend, for some slope action.
Various aircraft featured in some of the recent posts were flown for the first time and all flew without a hitch, Teddy Brown got to see Volksrust from above.
Conditions were excellent on saterday and with Paul and Izak from ETB and Gert from Secunda and Glen and Arthur from Durbs joining us we had a good bunch of slope enthusiasts , the hooligans did not make an appearance so the slope was an absolute pleasure, the frequency control was done by pilots just talking to one another, its so easy when handled this way by pilots with a little savvy.
Saterday was the best wind we started flying at 9:00 and finishing with valley release on the slope at sunset. (see photo with jet trail).
Peter really seems to have his big Astir CS sorted now ,he had 6 successfull flights , logging over two hours of airtime, he practised launching with Charl our official big glider launcher and landing approaches, of all the gliders flown from the fuselage mould, I have made, this wing layout and foil has the most gracefull flight characteristics, Pete's got a winner here.
The 4MTR Dianna SZD56 had a very succesfull flight and is now also sorted, a little more nose weight and the twitchy-ness is a thing of the past, this glider has a very flat glide slope and responds to thermals very well , I flew a full hour with her on saterday from thermal to thermal and find this medium size, less tiring than the 6 mtr ships.
Finally my Swift S-1 had another flight after the flutter/crash flight it had in january note how green the veld is , anyway after the rebuild it also performed well, it is quick (MH32 FOIL) and rolls well , no sign of tip stall in tight turns and does what an aerobatic glider should, its smooth and fun to fly, it also needed a little more nose weight, but is now sorted. A bit hot on the landings, so I need to find a way to slow her down, probably program in some Flaperon, at some stage.
Izak maidened his full (really full) carbon Toko which was built for DS and it seemed to go like stink(Charls expression). In the Saterday blow Izak's Toko, Paul's Trinity f3b and Flippy and Pete's Prodij , Charls Aero , and Mikes Jart ,all screamed about , giving the pilots their daily adreniline rush ...great fun.
Peter's son Chris flew and maidened his home brewed hybrid the"Bastardo" to great effect, it looks good in the sky with its swept wings.
Sunday saw light conditions but strong thermic air, once the valley warmed up, out came the electric assist gliders, barring Glen who seems to also be able to fly in these conditions with his Weasel foamie which works in light lift, quite amazing.
We all put in hours and hours of gentle soaring from thermal to thermal , at one stage Izak had his gentle lady 2mtr, above us at speck height and I have no doubt if he had not spun her down, she could have continued upwards out of sight.
Monday we die-hards went back up the slope , but the conditions indicated on the spot graphs were high pressure and very little wind, and so it was. So we invented a new glider class F-Slope-J a one man hand tow.
The line is limited to 10mtrs and 600kg ,breaking strain with two heavy duty galvanised rings(a tow rope actually) and 6 x strong rubber bands.
Piet got his Tsotsie away like this on most launches out the front into the thermals, never a dull moment with the Berg guys.
Unfotrtunately nothing slope planned
for the forseeable future, so we will focus on
flat field flying.

Some great company and really super challenging flying conditions contributed to a really outstanding day of flying.
Turnout was a little disappointing for such a great day with many of the B.E.R.G. big names not
showing, Mark and Kurt Stockton opting for MTB and Evan having his combi break down on him.
ETB and MMS were well represented and Simon, Ian and Conrad got together to practice for the F3J world championships. Volney and Johan did the towing for the junior team - hope you guys took it easy the rest of the week in recovery - hand towing is tough, especially in those light wind conditions.
Lionel did some damage to his ankle while towing for the MMS team with Johan jr and I notice MMS just reverted to winches for the last rounds.
Rudolph Engelman was our B.E.R.G. single man team and fortunately Tony was around to help with some timing. Charl did a great job of directing the contest (although it would have been nice to have him announce the pilots before each slot to prevent a few confusions, one of which I think resulted in me
slipping from 3rd to 8th place. I really thought I had you beaten at the prizegiving, Piet).
Celeste Rheeders helped with the computer scoring and Trevor Austen showed up and kindly donated a winch to the club. We were also visited by Herman and newcomer Barry Lamb during the contest - hope to see you guys flying in these contests soon.
Below, the MMS team's collection of models and equipment.
Below, some landing techniques: left Simon Tladi and right Paul Carnall, both putting in some good landing scores. Sorry for the poor photo quality - it wasn't a good photo day for me or Martie.
The only serious casualty of the day was Johan Bruwer whose Pike Perfect crashed when it flew over other pilots on landing approach (looked suspiciously like PCM type lockout to me). But Rodney was without doubt the entertainer of the day: on the left in trouble in a not so good position for landing with a few seconds left on the clock and right, yep - in the trees again.
Rodney has managed to put a model into the trees consistently in the last three contests. We don't know yet where the next HTL will be flown, but I sure hope for Rodney's sake that there won't be any trees there! See you all at the next HTL on the 13th of July just after the F3J World Championships in Turkey . . . or maybe on the slope at Volksrust this weekend.
Also, please scroll down a few entries for the pictures from the Nationals. I had reserved the blog space but until now just didn't have time to finish the posting.
Note to blog contributors: I've modified the blog master template to set the content width to a fixed 700 pixels. This will give contributors better layout control so that when the reader adjusts their window size, the text and pictures won't jump around and reorganise themselves untidily.

Having missed out on the Sungazer event , I eventually managed to get hold of a CMP Discus 2.6 M almost ready to fly glider. I have not flown Scale gliders before one thing I was told is that a Scale glider must have a pilot (preferable scale too I presume). So looking at the pictures that were posted on the Sungazer event I saw some interesting scale pilots ranging from true to suspect scale to true scale Shrek.
Scale Pilots that one can buy from your LHSTrue to suspect scale (This guy is called Harold by curtouesy of Paul from AMT)
So not wanting to pay R75.00 for a true scale pilot the next option was to raid my daughter’s toy boxes for a prospective pilot. After some discussion on which toy she did not want any more and an interview with the remaining candidates’ Teddy Brown came out on top. He gave me the assurance that he was now tired of just sitting on the shelf and is ready for some flying action.
After some more flight briefing and testing of the new flyby brain wave avionics systems the canopy was closed and all is now ready for that all important maiden flight.
The pictures below show Teddy Brown seated in his new CMP discus glider.
