Frocester landing

Many of our members do not like to fly at Frocester because of landing worries. The pessimists may like to read this article The optimists  should look at these movie clips Pegase8,wmv the ideal landing approach is 1.40 minutes into the clip although there is no landing until the end , notice how the model slows in the compression . The other  also by Ian and  shows  landing a zagi and a 3 metre model . The landing is very safe as the model is nearly stationary, it is the approach that needs courage  Please note, the brambles can cause minor damage to large film covered models

Virus warning
C-Nile Virus Warning. It seems that there is a new computer virus called the C-Nile Virus that even the most advanced programs from Norton cannot detect. It appears to affect those of us who were born before 1944! Symptoms of C-Nile Virus: it causes you to send the same e-mail twice; to send a blank e-mail; to send an e-mail to the wrong person; to send the same e-mail back to person who sent it to you; to forget to attach the attachment and to hit "SEND" before you've finished writing it.

The MSA need a new/second hand slot timer.  Do you have any
ideas how we might lay our hands on one?


It would need to contain a microcontroller based timer circuit referenced to a quartz crystal, a large clear LCD display and a low level audio output for an external PA system. The user must be able to select from standard pre-programmed time slots of 8, 10, 12 and 15 minutes, and for warning tones to be output when the countdown periods reach 2 minutes to go, and then 10 seconds. In addition, the user needs to be able to program any time slot up to 59 minutes for other types of competition. All time settings should be shown on the LCD display and the current countdown figure. The system must run from a standard 12V automotive battery, making it ideal to transport and set up quickly at any location.

F3F racing Sunday
Was quite a good day out yesterday, had several 51/52s until later in the morning when things became a bit more stable and then was running in the mid to late 40s (fastest time: 45). Last time was a 49: spent most of the time retrimming the model as unbeknown to me my servo tray moved again giving me loads of down trim. Should have been another 46, but never mind.

Had a top 10 finish with 20 runners so can't complain really: not as rusty as I thought I'd be and am looking forward to competing in a few races this year.

Sorry no pics: light was crap.Did get a sun tan though...?!

Will probably be out in the week.

Tuesday at Frocester, 20 MPH till late afternoon when the wind went light but enough lift for Alan's copy of a Phase 6. This was very light and  easy to fly in light lift. We had the usual argument,  Alan wanted to put another 4oz in the nose and I thought 4oz should come out.  Andy had a fly on his way home from work with a Nyx

Wednesday at Selsley, It can be annoying when the wind keeps changing but today it went from the west slope to the north slope and back to to west, just a short walk. A very warm day for the time of year, where were all the scale fliers? 

This  Rutan Defiant passed  overhead see  for details

Thursday strong lift at Frocester but feeling cold in the strong breeze

Friday a fresh westerly and not very warm

Two weeks ago I had a go at explaining the mixers used on a modern model to the power fliers at Astondown, three mixers in with just a few minutes gone I was getting a few blank stares. 

The idea is to set a model up for its optimum performance and make it nice to fly.
Ailerons on a model like this need to go up a little more than down to get a nice roll. Flaps need coupling to the ailerons to get  a good roll rate. Flaps and ailerons need to be lowered to allow the model to climb well. Elevator to flap coupling makes it turn tighter. Crow braking makes landing very easy, the flaps go down  and the ailerons go up a little to avoid tip stalling , down elevators stops the pitch from altering and rudder coupling is switched in with the throttle stick , this helps with control and makes landing very easy

Photo Crow braking deployed, with this amount of flap it will fly slow enough for me to catch it

Mixers used, differential ailerons, aileron to flaps, flaps to ailerons, elevator to flaps, flap trim, ailerons to rudder, speed, start, crow braking, side adjuster to trailing edge, brake to reverse differential, brake switches in extra aileron to rudder coupling and more down aileron to compensate for the crow
30% Differential has been used on the elevator and ailerons this has made the controls smoother and more progressive

For details and further  reading go to  and an excellent guide that also applies to sport models

Do you need it? Yes, Tuesday I flew my Pegus 1/4 scale with the differential badly set and it tip stalled, I landed adjusted it and it was back to its good natured self. When ailerons are deployed the model should roll with no pitch change, a slight amount of down pitch is often OK with a scale model.


Malvern auction, plenty of time to view the models, rather too much while all the sale items were slowly entered into the computer. When the auction finally started we had a detailed description of a plethora of books, this seemed to go on for ever, most sold for a £1. There were a few quality models and many thermal type models.  The Hawk  looked good.. Adrian bought a Calypso Contest T  and I bought a moulded  HLG . Doug sold his PSS Tigercat and John Parker bought a 60 slope soarer. The money was settled very quickly but  finished at 11.00PM   too late to get a pint. total sales £1100.

Indoor Flying – 1st Attempt 

Having been over to Chosen Hill school a few weeks ago to have a look at the indoor flying, I decided to give it a go. To me, it seemed something like a Crash model (from Robotbirds) or a Mini IFO would be a good model to start on. These are both small and light models, which should work well in the small hall. The bigger & heavier models just zoomed around “wall of death” style which looked a bit hairy. 

So, having deep pockets, I decided to build my own model. First things first, onto eBay to get some 3mm Depron. This was duly ordered, only to find out 3 days later that  Tim that had bought a stack of Depron and was selling it at ¼ of the price I paid (Doh!). 

Next was the radio gear. My eyes fell upon my old Piccolo helicopter gathering dust on a shelf. Five minutes later I had stripped out the 3 servos, receiver & Phoenix 10 speed controller. Now all I need is a motor and 2 cell Lipo pack. Back to eBay and a brushless motor is winging my way for £9.50 from Hong Kong (RevolutionShop). Then onto RCM Direct for the Lipo battery and some carbon strip. 

A couple of weeks later all the bits had arrived, so time to break out the scalpel and glue. A Mini IFO shaped piece of Depron was cut out, edged in carbon strip and various bits of radio stuck to it. Model built, onto the flying!  The longest part of the construction was thinking up a name. I eventually came up with I-Ope.  …As in I ‘Ope it flies J 


Over to Chosen Hill school on the 10th March, let’s get it in the air. I connected everything up, waggled the sticks, here goes….    

Oh errr, the room looks awfully small now that I’ve got a transmitter in my hand! Anyway, model on the ground, full throttle and take off. Followed ½ second later by the I-Ope flopping into a weird half loop and heading straight back at me. Then another ½ second later, a crash as I cut the throttle and it hit the floor. Hmm…. 
After much discussion,  more crashes, test flights by Chris Bishop (thanks Chris) and ½ gallon of hot melt glue, we worked out the C of G was wrong. Moving the C of G forward 2 inches (!) transformed the model and I could fly it round in slow circuts. PHEWW!   Now all I have to worry about is the walls! 
A couple of flights later, the I-Ope finally cried enough as I’d pretty much reduced it to a few bits of crumpled Depron and broken carbon (see photos). 


So time to go home and build I-Ope 2. This will be pretty much the same, but much stiffer (hopefully). I discovered that if you gave it full throttle, it warped the LE of the wing and I got a lot of down thrust  ….not helpful J If you fancy a go, make sure you build something LIGHT so you’ve got half a chance of flying it slow enough so you can control it. A 2 cell LiPo is more than adequate and something like a Shockflyer would be ok, as long as you keep it light. 

Incidentally the photos are the “after” shots. Don’t laugh at the big hole ripped out of the front after the last crash, it’s not funny!   .. Well it is really, but not as funny as the bent prop and the slash in the wing where the prop stuck through it after one “flight” 

Regards, Mike
