Thank you for your reply, the model is called Katrina drawn by Alistair Sutherland, who used to write in the model mags .The wing section is clark Y. The tail plane is flat. I am building this for winter use to fly off our field when it gets water loged in the coming winter. Thanks for your help Art...

Hi I would apreciate some advise please. I am building a none scale sea plane from a plan, there are no thrust lines shown. The engine is mounted on a pod facing forward above the wing,and i wonder what the thust line should be. To my, may be wrong way of thinking with the engine above the wing / fu...

Hi Graham You do not state how many channels you have on the RX, you need one for each servo that can then be set up individually and assigned to the same switch. If you have to use a Y lead you can get a servo reverser that will plug into one of the servos in the Y lead ,how ever what ever adjustme...

Hi
if you get stuck .SLEC do a 1/4 scale grp cowl for their Stampe by plane , might be of use, pretty close to a tiger moth.
Good luck
Arthur

Hi I have just acquired a old Z38 with a rear exhaust and no choke carb. The silencer fitted ( silver in colour )is the same as I see in pictures of this engine, however there are no exhaust down pipes as such, just a few slots cut in the silence to let the exhaust gasses out. If fitted in side a co...

Hi Hope this helps If the complete carb is inside the fus it will monitor the air pressure inside the fus and regulate as required.no problem How ever if the carb has a bell mouth extension fitted and the carb body is out side and the bell mouth is drawing air from inside .you need to make the fooli...

Hi Stuart Re batteries ,size for size lipo are half the price ,the higher voltage of life whilst ok for Rx use is too high for the 4.8 volt servo`s I use. So which ever battery I choose it would need a voltage regulator Just to rekindle the two battery debate ,I did as a lad i power my models with a...

Thank you for the info Rob just what I need.

Hi I am looking to use a 2cell lipo to run a 4.8 volt Rx system, but can not find any of the voltage regulators that used to be around. So me thinks could i use the BEC side of a electric speed controller to run the system , ( not running any electric motor just 4 servos and the RX ) Thanks for your...

Hi Some advise please. I have been using multi pin plugs ( commercial type 15 pin ) for some time now to make multi servo connection easier. ( wing to fus ) In use now for two years I noticed ,at the start of this years flying that one of the servos would not work, usual checks , what had happened w...

Hi alL I read the following advert in a model mag placed there by a well known dealer.It may not be LMA matrial but It made me smile. Model aircraft diesel engines for sale, etc etc. available with a balanced crankshaft for £10 extra. Now it seemed to me that a balanced crankshaft just might be a go...

Hi Scott I have just read your post ,twice in fact as I could not see the reason for you to send it . The make of car I have is totally irrelevant as the model will either fit inside or it wont. In my case the wings will and the fus wont. Hence my inquiry about two peace fus. I have since found a po...

Hi Barrie The product you need was called Primol, made by Solafilm. no longer available. Back in the old days I used to clean car tyre inner tubes with a liquid that had the same distinctive smell as Primol, before applying glue then the patch, It was known as Tip TOP solvent cleaner. I wonder if so...

Hello Every one I would appreciate some advice regarding on/off switches as used with a Rx battery pack. (2cell lipo ) I have in the past used JR switches Now I have looked on the web and I find that JR type switches are very much cheaper than those with a label on them. But are rated 3amps at 240 v...

Happy Christmas If you are reading this to day you are probably like me on your own, but no problem, more time for building. Please take the following as a serious question, and not as I am told by fellow club members that I am just causing trouble by asking the following. The height limit is 4ooft ...

Thanks for the info John.

Hi
Could some one please tell me the correct plug electrode gap on a NGK CM6 spark plug as fitted to a OS 33 petrol engine. As there is no mention of this in the operators hand book.
Thanks for your time
Arthur.

Hi Stuart As I am even older than you perhaps it qualifies me to make a comment.So with due respect hear goes. I have always believed in the keep it smiple idear I can not help but wonder how many over heated engine runs you will get, and crashed models due to an engine stop or sieze before you get ...

Hi I am looking for informatiom related to the construction of a two piece fusalage .(Needed to fit my car.) I have been looking at a Wellington kit for some time now ,and due to the present stay at home rules ,it could be a good time to start it. I figured on cuting just behind the wing but not sur...
