    thanks everyone. Diacov looks just the ticket. Strong, light ,easy to apply and no sagging in hot weather (Fat chance at the moment). AND AVAILABLE !!!

    Evening all. I am trying to locate a UK stockist of SIG Koverall but without any success so far. I have heard good things about its properties but finding it is another matter. Does anyone know of a lesser known stockist ? If not, can anyone suggest another product that is similar. I am looking to cover the rear fuselage of a Brian Taylor Hurricane so i am looking for a robust covering that wont suffer like SolarTex on hot days and offers some strength to the structure without any sagging/bubbling. Any suggestions appreciated Rich

    Thanks to everyone who has replied. i have had a look at the flytron kit and it looks just the thing. i definitely need 'plug n play' type lighting because while my building and engine tuning skill are good, my knowledge of electronics suck !

    Hi all. i am looking to put red/green nav lights into a model i am putting together but have a limited knowledge of electronics. I have seen Hobbyking do various pre wired led sets but there is nothing in the specs to indicate a working voltage or if any resistors etc are required. see this link - Hobbyking LED has anyone used them, know the voltage and how bright they are ? also how hot do they get .. i dont want to melt the plastic wing tip lenses any guidance appreciated Rich

    Afternoon all. I am currently using my trusty Futaba T9ZAP with a 2.4 module to run all my models with FASST rx's. I am considering treating myself to a new Futaba Transmitter but it needs to be FASST as i am not changing all my current models receivers. What is everyone running and how easy to get on with ? cheers in advance Richard

    WE HAVE A WINNER !!!! the Hild Marshonet it is ! thanks to Steve and Martin

    Hi Martin nice idea but i am positive it had obviously well swept wing sets - very odd looking thing

    now this might be a long shot but i am trying to find out the name of a model that was a magazine feature some years ago. It was a vintage style bi plane with a forward swept bottom wing and rear swept top wings. I seem to remember it was a real fullsize design circa 1920's ? extensive internet searches have not revealed it - can anyone shed any light ?

    a local family has donated their late fathers models to our club but i wanted to find out what they were, age, etc. the solar film covered one is a 2 channel model while the other is a free flight bungee launch with a mechanism to activate a small rudder as the bungee releases. any help/info appreciated. (oh and if someone can shed light on the purpose of the metal hooks on the top of the tailplane...they are puzzling me) cheers Richard

    thanks for everyones input. just placed the order for a 2200kv motor and made up a fly lead to connect multimeter in line. hopefully all will be fitted and tested in a couple of days and ready for some seaside fun when i go to the coast in a couple of weeks
  14. richard cohen
    cheers all for confirmation on the motor. Its currently fitted with a Turnigy 40 amp ESC. with regard to test current draw, i was going to make up a lead to connect my multimeter to the model - do i just need to connect in line on one of the 3 motor leads or does it go between battery and ESC ? once i know the amperage draw x by 11.1 v gives me the watts - what margin is safe on a 40amp ESC ?

    cheers guys, clearly the guff i read about 15,000rpm for outrunners is tosh ! i have found a higher Kv motor - could you advise if you think this might suit - i dont want to spend a fortune on a motor for what is a fun fly model for me this one seems a bit shorter than stock so i would need to space it out or shorten cowl **LINK**   Rich   Edited By richard cohen on 31/07/2016 19:45:40

    i'm a dyed in the wool i.c flyer but decided to join the 21st century with a HK skipper and its a proper hoot but flying for over a year off water has taken its toll on the motor bearings and i need to replace it. There are no markings on the motor to pattern a replacement. model specs are: Specs: Wingspan: 700mm Length: 970mm Wing Loading: 25g/dm² Flying Weight: 575g Motor Thrust: 850g its running a 6x4 prop and motor size is approx 29mm dia x 30mm length powered by a 3s 11.1 1500 lipo I have purchased a 1400kv A2212 2826 10T as it a similar size and specs indicate it will provide around 135watts on a 6x5.5 prop but having fitted the motor, its power is marginal at best on the 6x4 or the 6x5.5. it wont take off from grass like it used to and required a handlaunch and pottered/struggled around the circuit. A larger prop fouls the fuselage so not an option but I really have to get enough power to rotate off water so do i need more Kv ( i read somewhere that an outrunner can't do much more than 15,000 rpm so 1400 x 11.1v = 15540rpm seems about right. any and all help appreciated to a 'lekky newbie   Edited By richard cohen on 31/07/2016 17:55:29

    Hi Ian. nothing in the kit or die cut sheets that matches and nothing on the plan to cut my own. Just tried an email to product support at TopFlite but its bounced back

    Afternoon all i am midway through building an Elder 40 gold edition and so far all was going well but my problem now is installing the firewall. The instructions advise to locate the Firewall Mounting Gauge to ensure the correct right thrust. The problem is that i cannot find said gauge or anything which matches the picture in the instruction picture. As its a pretty important phase of the build, i want it right. Not sure if its a part missing from the kit, labelled as something else and/or redesigned to a different shape. Theres not a pattern on the plan to make a gauge from either. Has anyone built this model and know what i need to find ? cheers Richard

    i was torn between becoming a farmer or joining the Royal Marines. Realised that my body can't cope with cold temperatures so both outdoor roles were out. Ended up taking a saturday job at a garage, then an apprenticeship in the workshop, getting my papers, moving from technician to service reception, then to service manager for 3 franchises. Then got out of main dealership and now run a small independent garage - less stress, nicer customers, better hours (more time to fly). Biggest regret ?.....being offered an apprenticeship in a classic car restoration firm and thinking that making wooden chassis's, machining new pistons and panel beating to restore anything from early 1900 cars to 1970's race cars wasn't proper mechanics what a plum !

    Tony, kinda matches what i found but he seems to add even more rear weight .... where did you find the post ? Bill, its the small one (that said it's almost 1/4 scale )

    Hi all, anyone else got a Hobbyking CriCri ? recently bought one and found that with the battery in the recommended position the model was too nose heavy. To achieve the stated CofG, i had to move the battery rearward but the maiden flight showed the model to be too tailhappy by far. has anyone found a better CofG position ? Rich

    Ben, not sure where you are in the country but i have a set of Hanger 9 Cub wings with aluminium airfoil section struts here in darkest Wiltshire if you are interested for small contribution to the current lipo fund Rich Edited By richard cohen on 25/02/2015 22:07:40

    Hi Pete. thanks for the info. the BRC page is useful (even if they didn't reply my email) The power combo certainly seems to match your 100-150w per lb and if the weight comes out lower then i can always throttle back ! one thought has occurred to me. as the model lands on its belly, the current prop is quite flexible and has never broken on landing (i guess it flexes enough and then the motor rotates till horizontal). Will an APC prop have some 'give' or is it going to break, or do i need a folding affair like the glider boys use Rich
  24. richard cohen
    Hi Frank. thanks for the reply and good to know i can standardise the lipo packs. with regard to where to buy, i have tried emailing Robotbirds,BRC and Puffin but with no reply i kinda think 'how rude' and why should i use them but maybe i am cutting off my nose etc. my only other experience was with hobbyking for the Skipper purchase and prices seemed keen but i'll be guided by the forum if you have suggestions.

    evening all. While an experienced pilot and LMA member, i have only just started playing around with electric flight. My first forays have been with a HK Skipper and it is a hoot but it does come with the hardware supplied so i didn't have to think about the setup. Some years ago, i bought a parkzone spitfire (again it all came complete in a box) which i kept in my workshop for a lunchtime flying fix in the local park. I never considered it a proper model as it was 3 channel and on 27mhz but it served its purpose and then got shelved. Well now i am looking at electric flight in a new light i thought that it ought to come out to play again but instead of the brushed motor/gearbox and Nimh set up i ought to see if i could cheaply change to brushless/lipo. My problem is choosing the set up. I have read lots of threads, articles and the like but my failing is numbers ....they just don't gel in the old bonce. (which is why i prefer oily items). I emailed 3 leading electric flight specialists but have never had a reply so what i am looking for is advice on a motor/esc/prop combo which will provide adequate power. The model is 36 inch span and currently weights 1 pound without a battery. If i could utilise the 3s 1500 lipos from the skipper that would be helpful. I don't want to spend a fortune and don't want a pylon racer, just enough go to perform scale flying and basic aero's. any help would be very much appreciated Cheers Richard
