Thread: What's your club membership size & fees?
29/09/2019 12:55:30

Our club also has full facilities with clubhouse and hot/cold water and kitchen plus toilets. We also have a storage shed and lawn tractor. We have a large E/W runway and a NE/SW one which helps with crosswinds . We also have a lot of flying tables . Our biggest cost is land rental but also a fair bit is spent on ground maintenance all in all the 100 annual fee is very good value.

Thread: Thank You SLEC great service!
20/09/2019 16:41:25

Hi chaps just wanted to give a Thank You and big thumbs up to SLEC.

I’m building their very nice 80in Chipmunk kit and found that the balsa leading edge strips were slightly incorrect width. While it wasn’t a disaster it was a bit of a pain as l didn't have any similar stock to replace them with and didn’t want to join two bits.

Anyway one call to SLEC and they couldn’t be more helpful. The next morning they sent the correct size pieces plus one spare 😊👍.

I really like this firm . They are really helpful plus they support many shows etc .

2b4e1fdd-9c7f-4f99-aa41-4fa37d779ba0.jpegA bit more done today . I partially assembled the right wing. Instructions say left first, I’m not quite sure why though. The wood fits well together but doesn’t seem to exactly match the plan. The tabs underneath the ribs and central spar web do help it all to line up . Some bits of the instructions don’t seem quite right but I will have to see. Here is how far I am now . I will add stringers tomorrow.

Cheers Ash good to hear , we can compare notes . I will post photos as I go . I’m looking forward to getting into this one. I’m also looking forward to flying it as I used to really enjoy my smaller 60 sized Blackhorse ARTF Chipmunk. The two piece wing uses a ply brace which certainly looks very solid. So far I’m just doing the early stage u/c bits on the wings

Hi fellow flyers ! Today I started the build of my SLEC Chipmunk I had bought at Wing and Wheels in June. The first thing I did was pencilling the numbers on all the parts to avoid confusion. I started with epoxying the undercarriage supports on the ribs. It is the RAF trainer version which many are familiar with in full size . I chose it as my first 1:5th scale substantial size build as it seems relatively simple to build rather than some of my other favourite war birds plus the Chipmunk is a great easy to fly plane not requiring retracts etc. I decided to buy the kit as it gives extra control of the build rather than having to put up with an ARTF build that has been finished to hit a price level. I must admit I’m no expert builder at all and don’t really like painting. The kit is well cut from quality wood, and the plan and instructions quite detailed . The cowl is really substantial fibreglass and the canopy good quality. There is decent hardware supplied but I’m going to use some spare Oleos on the legs. It’s a nice big model which still just fits on the bench. I’m pleased the wings are two piece! Spares are also readily available at SLEC Which is great to know and a BIG plus versus ARTFs. 49197768-5e26-4ac4-a78d-f543d0c9e257.jpegI did build a Warbird replicas LA7 just over a year ago and I like that so hopefully this one might be better. I’m still debating whether in painting this or film covering it but that’s further on. It will be powered by my trusty Laser 180 I have spare, so there will be no shortage of power!

Thread: Petrol Engine for a Toot Sweet
15/09/2019 20:45:17

Martin explains it very well I think. Methanol is a wonderful fuel with a high latent heat of evaporation that helps draw heat from the engine. It also has a very high octane and resists pre ignition much better than petrol and allows us to use higher compression ratios and high rpm . It does require a much richer mix than petrol to burn but that is still an advantage as the fatter mixture extracts more heat . Petrol has a much higher heat or energy value than methanol ( about 10 times as much ) but it requires much more oxygen to burn so needs a far leaner mix . The difference between methanol and petrol mix, is that the petrol mixture requires around twice as much oxygen for a given amount of fuel. For smaller IC engines is very hard to beat glow for simplicity easy handing and performance.

Cheers Ron . I hope all well with you . I built this as a “warm up” for my SLEC Chipmunk , and it had been hanging around for a bit . I will let you know how it goes. Hopefully it will be a nice laid back model for lazy afternoons ... hopefully I can maiden this weekend 😊

Here it is finished. Now I just need to balance. I fitted a tow hook so cut a section out of the bottom skid which I glued on last . I made the pilot from balsa scrap carved with a stemmed and acrylic paint...that was actually very easy and fun. It’s great on this build not having to paint!!! Just need to program the aileron differential too. 181e41b5-4940-4566-b749-16c335deeae6.jpeg

Here is the plane almost finished. I used Deluxe EZE Kote to paint and reinforce the balsa. I also used it to laminate the wing bandage. It is a polymer rather like Ronseal water based floor varnish and dries hard but seems to stick well to film covering with heat . I decided to make the wing one piece using a wing bandage and EZE Kote laminating thin glass cloth. This should save a bit of faff and weight.  I didn’t want to use solvent based products and this seems to have worked well . I had bought EZE Kote a few years ago to laminate a veneered wing but was reluctant to use it then with fear of the water delaminating the wing . I’m sure thinned PVA or thinned Aliphatic would work just as well for finishing the balsa. I did use epoxy and fibreglass on the nose floor section to strengthen it for landing. 79fcd946-bc6e-41c4-936a-f5fd9d7b0203.jpeg

638f7192-07ca-46aa-aa61-143a46892ce4.jpegHere is my just finished Westwings Skylark glider . I built it with a tow hook, so it can be launched with piloting by club mates of my Wot 4XL tow plane181e41b5-4940-4566-b749-16c335deeae6.jpeg. The kit instructions were a bit vague on the wing joiner and I decided to build the wing as a one piece and I’m pleased I did as it saves a lot of fiddling around plus I think it might be stronger 😊

RIP Brian and condolences to his family Like so many other Modellers round the world I have really enjoyed his columns over many years. His entertaining style and resourceful home brew short cuts and advice will be surely missed .

Thread: Wot 4 xl so it's a OS 91 surpass or DLE 20 petrol......Thoughts and advice needed
24/08/2019 14:25:27

Yes my OS 120ax two stroke is definitely a glow guzzler! Especially on full throttle. Most of the time I fly the plane at half throttle so it isn’t too bad .  Another thing I added on this plane are “up flapperons”  as I find it wanting to carry on floating in light wind landings. The flaperons shorten landing and provide some braking plus are a fun feature to use. The tank on the Wot 4 still gives a good 15 min though. It has great idling and good flexibility but a four stroke is definitely preferable. It just that I had the engine for a number of years and it fits . The laser 155 in it or any of the big OS 4 /asp 4 strokes would be nicer plus less thirst. The four strokes also have smaller exhaust cans. The 120ax muffler is huge.

Thread: Hands free mobile calls

I have always had some issue with “emergency driver police chase training “ as sadly the pedestrians or other road users who walk out or accidentally move out in front of vehicles traveling at excessive speeds will not have had the training. It’s sad but a ridiculous situation we endure primarily due to cost and political expediency. It would be easy for the government to regulate that vehicles must have ignition kill devices fitted which could then be accessed by our emergency services. That would negate the need for high speed police chases on our public roads. Sadly it doesn’t seem to be politically acceptable and as a society we are happier to sacrifice more lives than have our “freedom “ curtailed.

Thread: Wot 4 xl so it's a OS 91 surpass or DLE 20 petrol......Thoughts and advice needed

Agree with Martin. On this sized model I think glow engines offer a far easier solution. My Wot4xl is powered by a 2stroke OS 120ax which is quiet and very powerful, so it’s a great tow plane. I used the add on Ripmax servo operated wing tow attachment. I also reinforced the wing joining for extra security with two additional wooden dowels in the wing as the standard two wing bolt and single front tab can lead to damage to the leading edge as the wing vibrates in its slot. I think a good four stroke 120-155 glow in this plane would be ideal . My two stroke OS 120ax is very strong and quiet but the alternative four stroke engines use less fuel and vibration is probably lower.

Great to hear Colin I think the sleeve protector Is a good idea and it should be quick and easy to put them on for a launch. Many sports and pass-times require it as sadly our flesh is about as vulnerable as a cucumber! and almost any fabric over it reduces injuries. When I mountain bike my “summer jersey” has 3/4 length sleeves with tough nylon fabric on the top side of the sleeves just to prevent thorns and nettles damaging the arms on overgrown trails. The right clothing makes a massive difference to enjoyment!

09/08/2019 14:16:11

Sorry to hear about that Colin and I wish you a speedy recovery . I do wonder whether designers could consider some sort of load based clutch on electric motors rather like we use on drills. I guess that still wouldn’t stop nasty flesh injuries such as this though. Maybe a protective arm sleeve or having a coat on might make it a bit safer? Certainly there are fabrics that protect quite well from sharp cuts ( e.g. chainsaw trousers) . I guess an arm “ Launching sleeve “ wouldn’t need to be too cumbersome?

Sorry to hear that Paul . I must say that does make a really amusing story which you relate really well , definitely one for the tea huts. The idea of cycling a long way to fly and having to get the plain in the air no matter what also shows great youthful enthusiasm that we all had and often still have !!😉I also like your grassfibre pun. Must admit some of my planes have had a bit of grassfiber in after I have repaired the cowl with glue and noticed some errant grass inside.
