There's an article by tim hooper re the skystreak 26, he can't attribute the design. perhaps the attached photo will help.

My plan was obtained from www.model-plans.co.uk, sized up so so it's now a skystreak 48 powered by an OS 40 Surpass and with a pair of electric retracts installed in the wing. A second wing is to be made incorporating air brakes as per chris foss's wot4 as it's hard to slow the plane down. I used the flat top of the wing as per the article but in honesty it needs just a smidgen more. Also an extra bay at the aft end of the fuselage is a good idea, to extend the moment arm as otherwise it'll get twitchy, it's probably why the original c of g is where it's at, to stabilise it a bit.

It's also probably why mine has been rekitted.

BTW model-plans.co.uk is the baby of Derick Scott Plans Service and mine, including blowing up to 1.2X was £12. It's advertised in SAM35 Speaks.

Thread: Engine for largish cw Cub
03/04/2019 20:53:16

Hi Paul, I think it is.

I think yours would be far too powerful for me, I'm getting too old to fly hotrods.

Thanks.

I have an 80ish wingspan clipped wing Cub that weighs 7 lb ish. Currently powered by an old laser 100 that gives it about a 5 yard take off run.

The box says it suits a 90 -120 4 stroke, model dates back to the early 90s at least.

I'd like to fit a laser 80 that has very few hours on it will this be adequate do you think?

Thread: Banded on undercarriage
02/04/2019 10:22:03

Fit torsion bar u/c, I did on the thread "Undercarriage Upgrade" on this site on a BH Blade and have never looked back, at least a couple of dozen landings including two into very long grass and the u/c is still there.

If you prepare your work and have all the parts to hand it shouldn't take much longer than fitting dowels or alloy plate u/c and will be much more fit for purpose.

Thread: Vintage airframe coverings.

Heat shrink film is fine, it was developed in the usa before ww2 so meets any vintage requirement by many years.

It's your model and should you choose to use film and one of the vintage police criticises you, advise them to remove themselves in short, jerky movements.

Keep in mind that brushless motors and lipo batteries don't have the same history.

If you can get it, fibafilm is a fantastic material to cover with as is coverite's (unfortunately discontinued)micafilm. Both really strong and very light compared to the tex coverings.

Impex HT 1780 adhesive is better than balsaloc as a heat activated glue for fixing the covering.

Just my 2ps worth.

It has quite a long moment arm, perhaps that's why. It does seem to have inertia in turns with respect to the reaction to rudder input, which I initially put down to the fairly small size of rudder then, because I cheat and put an aileron/rudder mix on, found that the total throw was automatically shared between the rudder and aileron sticks. Hence if I want to get a faster response both rudder and aileron sticks are shoved over.

I've flown it about 10 times now, on a day like today with virtually no wind, a 1/4 of a tank lasts about 15 minutes (it's an 8 ounce tank btw) on the other occasions when I've flown it's been quite windy and 15 minutes can take about 2/3 of a tank because of increased throttle to keep her moving into the wind.

img_0117 (1).jpgI wish I could say I built this model, I didn't though but it's a beautiful slow flyer and lands like it's on rails, thanks Barrie.

It's a design from 1939 called the "thermal Magnet" I fitted an OS 40 FS , one of the originals, that I bought in the early 80s in the last century. I fitted an orange faast (futaba) rx which has a 3 axis gyro. It's fitted with a 12x4 wooden prop and drinks 15% liquid gold, very slowly.

It's really peculiar when the gyro is on, really squirrels when one tries to intercede but it's fun and very satisfying to fly slowly.

A buzzard spent some time with it in a small thermal and that was an unusual event in itself.

I spent quite some time with it in the air and now I have to order some more wing bands before the ones I have let go.

Half a dozen more landings plus several touch and goes, got to be a vast improvement.

19/03/2019 16:18:23

Flew the plane today, success, several landings and only bent a bit yes. Time to cover it now.

One mustn't forget that Scotland have a great track record of upsetting England - you only have to look at last year. Never write Scotland off when playing against England I say.

Not at HQ they don't.

Can I just say thanks for starting this thread. I looked up the model on his website and, lo and behold, there was the basis of the fuselage joining method I need for my flair scout series and my Ruhig Tiger.

The two I forgot were a hangar 9 pulse 60 and a kyosho Calmato 60 low wing. Duties were shared with both SC61 and 91 two strokes.

Suffice to say I've swapped or sold all the engines mentioned except the 91Fx and the 61Fx.

This seems to be a common theme on many websites, I tried to be disciplined and finally came down to an OS 91 Fx.

My 91 has been in very many airplanes from a kit built acrowot with a 14x7 3 bladed graupner up to an Xtrawot with a 14x6 apc and with two dragon ladies, two WM midget mustangs, one BH midget mustang and a Goldberg ultimate in between. There may be a couple of others but I can't remember what they were but basically anything 60 sized.

I used to swap engines quite a bit and the 91Fx shares the same mounting footprint as the O 91 FS, saito 125 FS, Yamada 110/115 FZ and not forgetting my OS 61 FX.

It's been the most reliable engine I've ever had and I can't remember the last time I changed a plug.

Most of its time with me it's been fed 10% liquid gold but recently I've upped to 15% liquid gold and it still hand starts easily.
