Editorial Lots of cheap depron again, please excuse me, it's the way my interest has gone this month. I managed 5 days of slope soaring last week so I haven't completely changed to power flying. |

My Toilet Seat model, just a sheet(
CB uses a similar word) of Depron really This was made in a hurry as a small robust indoor model to fly at the Gloucester sessions. The motor mount has been strengthened with 1/32 ply, the fin is glued on and elevons selotaped on under and over. Two pieces of carbon fibre stick down from the front to keep the prop off the ground, it would look better with some tiny wheels. There are 2 skids below at the back to keep the elevons off the ground. Flying As with all flying wings the C of G is critical, a rearward C of G on the short blue marks stopped it flying, it's now on the transverse line and is very stable in pitch and roll. |

It will loop and roll
OK indoors and hang on the prop but for not for long as a rudder is needed for
this. Rolls are very fast but the nose drops making successive rolls difficult,
I am not brave enough to move the C of G back, It can be flown slowly
with the tail dragging ( how do you drag the tail of a tailless model?
) or go too fast for indoors. Outdoors it copes well with a
bit of breeze and turbulence If I made another the only thing I would
change is the elevon width, increasing them to about 1.75
inches.

The week last week Monday light lift at Selsley, Andy flew his Calypso, never enough lift for it to make that distinctive hollow wing sound. Tuesday Selsley again, more lift - John Godard flew his Nebula, this had the usual tip stall problem. The wind dropped at 3.00PM allowing me to fly HLG for while. Selsley - Wednesday Jan 31st –
lunchtime. The West bowl at Selsley was at its very best.
Strong, smooth lift to die for. Only trouble was frozen digits and
streaming eyes. The good old MiraJ didn’t care a damn. ‘I don’t
get cold’, it said as I yanked another pylon turn and a couple of
rolls. Nice landing for my MJ and help for Den arrived. You guessed, good old Bob Steadman.
Big rubber bands and lots of sticky tape and Den’s Wannabee was,
repaired and ready for Bob’s clinic. Off it went – splat. Again
splat. Put some lead on its nose Bob said. More tape, lead and several
more splats and it eventually became reasonably well behaved and
flyable. Indignant Den insisted the CoG was as per plan and
there was no way you could get all this lead up the nose in company of
a receiver. I’m sure he will find a way because it was flying rather
well when I left to ‘get back to work’. Apologies for taking the Michael
a little Den (and Bob). Any rate, amongst all that excitement Bob flew his
almost new Talon mk2. Wow it rolls in a twinkle. Loops bunts and turns
on a sixpence. I was corrected when I commented that it looked a bit
‘twitchy’ by the explanation that it wasn’t but it was
‘responsive’. I guess he was right. Anyway, the wind was dropping off very quickly and
moving more to the South and the lift deteriorating. Therefore there
was a real danger that Phil might show up with more indoor flying
stories, his PeggySue and his camera, so I went back to work. (Sorry
Phil). A final plea. Where have all the summer softies
gone on these winter days, midweek and weekends. I wouldn’t dream of
mentioning Bill or Ade or Ian and I’ve given up on Andy F. Guy Editor, arrived 3.00PM when the wind went SW, the wind came back to west. Andy flew his blue foam vacuum bagged Zagi. I flew Bob's larger Tallon - went well. There is now enough light to fly until 5.00PM Thursday |
Friday at Selsley, this was the best day this week, steady lift dropping later in the afternoon. Every thing went flew well until about 4.00PM when the Zagis started coming down |

Joe's Zagi, barley enough lift to keep it in the air by sunset |
The lesser spotted Andy Freeman, brought out of hibernation early by the mild weather and strong sunshine. |
Saturday, not a lot of thermal lift
on Minchinhampton Common, but a very nice day. My light weight
Highlight found a few small patches of marginal lift. . I wized my
bits of of depron about for a while joined by Tim C with a very
aerobatic Depron bi-plane made for knife edge maneuvers. The
South facing slope at Rodborough was working well in the light breeze

Sunday started cold enough to freeze
the bits off a brass monkey, quickly warming up as the sun climbed.
The thermal lift was poor, most of the electric thermal gliders
failing to find lift. Lots of shockies flown. Paul flew his electric
pylon racer, very scary, Paul has to build the speed slowly, I get
nervous just watching.

Close encounters of the balloon kind. Tim landed his model to watch
the balloon come down, but accidentally knocked the
throttle open on his transmitter, his Yak took off without him
noticing. It took us a long
time to locate it, I found it on the driving range, it had nosed in with only minor damage
Pictured is one of Phil's fleet of depron electric models. The Depron, carbon, brushless motor and LiPoly battery combination is a wonderful way to quickly test unusual shapes. |

Sunday at Aust The start of the years flying on the salt marsh between the two Severn bridges. We were pleased to find the ground soggy underfoot and not underwater as we feared. Phil Wright successfully tested his new electric canard. This features the motor and battery mounted on the wing leading edge to get the model to balance. Once he modified the ailerons to act as elevons, assisting the the foreplane elevator, it flew aerobatics with ease. Tim Chant |
