|Thread: Cox 0,49 vs PAW 80|
The Black Widow is great little engine and with correct fuel will go like the clappers. The PAW 80 is also a great engine but totally different characteristics as already said . It really depends on whether you want out and out speed or pulling power/grunt. Cox for speed (and Noise) PAW for grunt ,
Good luck and have fun .
|Thread: Coverings: not sure...|
You can buy a matt finish iron on laminating film in very thin gauges (microns) I have some 32 micron but it's probably too thick for your model . Ask the control line combat flyers what they use. 10 micron stuff is available but getting difficult to find.

|Thread: Kyosho T-33 Shooting star|
I lost my kyosho T33 last summer after many years of brilliant flying due to a servo failure !
I had one of the originals that was hopeless and it was quickly moved on . Fast forward a few years and lipos and brush less motors appear ! I found an unstartted kit at Old warden swap meet for £45 so the mods began. I threw away the original fan and motor and bought a 4s 70 5 blade fan off eBay. The battery compartment needed modifying before the fuselage halves were joined to take a 4s 3600 lipo. The compartment was then glassed and fuselage joined. The model ,from standard is transformed and will easily launch into vertical flight from an underarm launch. A brilliant model !
Given what I have learned about edf I would definitely fit a 10 blade fan and balance before installing to get a proper jet sound.
If I could find another untouched/ unstaffed kit I would buy it in flash ,price permitting.
Will put pic on later when on PC as tablet is useless and keeps changing words ! Predictive text that I can't turn off !!
You won't be dissapointed .

|Thread: Grass Cutting|
Good for you Rob ￼
A big thank you for you ,your son and all the other emergency staff NHS, Police , Fire and Army who look after us in times of need and desperation.
Im a retired fireman( firefighter in modern parlance) and spent all my working life in the fire service on operational duties . Non emergency workers cannot begin to understand the dedication given by emergency workers to protect others from whatever threat comes along.
Those that criticise these emergency measures or have only to think about their daily activities , just think ; while your running out of or away from a dangerous situation these men and women are running in or towards it and putting themselves at risk.
Stop and think of the bigger picture of why am I being asked to stay in? Any incident while your out and about or cutting grass , will impact on the ability of the emergency services that are already stretched in some cases to the limit to respond. They have been cut mercilessly by cuts to funding by uncaring politicians of all parties for over a decade and now being asked to step up to the line and help us. In many cases those emergency workers have had virtually no pay rise in that decade !
If you must vent you feeling then get onto you MP and let them know your anger at our unpreparedness for a worldwide emergency and stop bickering about cutting grass and not being able to fly our toys .
By nagging your MP maybe just maybe they will not let this happen again as it surely will .

|Thread: Making Steel Fittings. Question.|
Look out for a pair of Bilbo cutters. Like tin snips but more substantial . They will cut car body gauge and thicker with ease. For cutting tricky bits I clamp one of the grips in a vice and put a piece of tubing over the other . They are not cheap but are often seen at boot fairs etc.
|Thread: Flat Car Battery from non-use of car|
Hi Romeo Whiskey . Most modern cars have sophisticated electronics that draw tiny current even when at rest. Provided your battery is in good condition it should be ok for at least three weeks and probably longer . If you can run a lead out to you car then a Ctek or similar charger/conditioner will maintain your battery for long periods of storage.Link.is for the Absaar model that is somewhat cheaper but a good little charger. I bought one of these a few years back and use it during the winter months when car is standing. If you do go for one of these make sure you buy one of sufficient capacity for you battery .
I did buy a solar powered battery trickle charger some years ago and was not impressed but solar panels have improved so may be a better option no summer is on its way ?
Another thing to think of during long lay ups is the general condition of the car , brakes etc . They will benefit from a drive around the block once in a while enough to get them hot and dry out any moisture that can cause corrosion .
lets hope it all goes well.
Keep safe keep well and keep your distance

|Thread: Sign of the times - funnies|
President Trump is talking to the nation telling them that they should be making more things at home in the USA.
he said " Why , this morning I looked at my television and it had "Built in antenna " on it , I don't even know where that is !
|Thread: What Traders are still offering Mail Order? Services?|

One of them told me they were also doing local delivery to the north Kent area while allowed to.
Keep well, keep safe and keep your distance!
|Thread: Vibration absorbing engine mounting|
I know meanwhat you but you say certain revs so vibes are from something out of balance and rev critical. I have over the years had engines that are just rough running out of balance engines ,usually the cheaper brands. No amount of prop balancing would help. Change engine and hey presto , a quiet model ! Even some props in years gone by were so bad that balancing was impossible.
I think it really comes down to Individual model engine combinations / actions to get quiet drum free model.

Don't bother with those mounts they will allow your engine to wobble all over the place. We used to use them years ago on backplate mounts on fun fly models like the Panic but they were made from a hard rubber so didn't wobble as much. If you take time to balance your prop properly , ex pun , it will greatly improve any vibes/drumming . Saitos are pretty quiet and smooth running engine. I have used rubber Rawlplugs to hold Mount to the firewall but no noticeable difference. Dubro aluminium engine mounts are very good with rubber isolation but expensive. A decent covering like solar Tex if available or oratex if you can afford it will also help.

|Thread: Can I or can I not fly?|
Why are even having this conversation? and why are some confused ?
Essential travel only for needed shopping or medical supplies . Limited exercise alone or with your household members.Only go to work if its an essential job. Simples
Very easy set of rules to understand really . Why even ask if its ok to go flying? The fool that does will be the first to moan about getting fined and causing our stre-e-e-etched emergency services even more grief
|Thread: 2 vintage engines, what makes please?|
I had a mighty midget given to me when I was kid and reckon the second engine is a Mighty Midget. I distinctly remember it had Mighty Midget engraved on the transfer port . The crank pin was loose and Alan now owner of Weston UK fixed the crank for me . Never got it o run and cant remember what happened to it . The 4 bolt ?

|Thread: Covid 19|
Have you noticed how quiet the skies are. Haven't been this quiet since the 9/11 attack . I live on the flight path into London and the skies are eerily empty .
As already said sounds like the diaphragm in the carb has gone brittle or has a small hole .Walbro or copy repair/overhaul sets are available on e-bay at a fraction of Walbro prices and are very good. The modern petrol with ethanol will eventually make the diaphragms go hard and brittle .
|Thread: Has Your Club Made Any Decisions Regarding The Coronavirus?|
Well done Gary. The trouble is finding any sterilising wipes or sprays to use ! All cleaning sterilising items shelves at local stores are bare here in south east , not a piece of soap to be found! Lady on the checkout said to us "I wonder what people did for washing before this ,didn't they know about soap"
We have cancelled all indoor and outdoor organised meetings until further notice. The flying field is still open to members for normal flying as it's easy to distance from other clubmates. As already said when a full lockdown is brought in then the field will also be closed.
Just wondering how I'm going to cut the long grass when we can finally get back out ?
Good luck to everyone and keep well.
|Thread: Motor stutters near full throttle|
I have had this problem on one of my planes. It sometimes wouldn't restart after closing the throttle but would just oscillate . Problem on that model was poor quality / connection on the bulit conectors on the motor leads. Another model with similar problem was a broken lead in motor.
|Thread: David Boddington Tiger Cat|
Just looked on Just engines and ASP 21's are now out of stock with little hope being re-stocked . You might be lucky and find one in stock somewhere.
Hopefully their new range of Taiwanese engines will grow as they only stocking a 15 and a 32 at the moment.
