  1. If going the Walwart route buy yourself a simple plug in timer, the sort of thing that you set to switch on and off a light at a given time. Set it up to turn on for an hour every day. Plug the Wallwart into the timer and leave your Tx and Rx batteries attached. Now they will get a top up charge every day. When you come in from flying set the overide on the timer to replace what you used in that days flying. It will then revert to the daily 1 hr top up. I used this set up for many years with NiCad and NiMh batteries and always went flying with fully charged batteries. I would be cautious about using it on a lithium battery.
  2. Just had a glance through and did not see anyone mention a simulator. Many people find time spent on them to be worthwhile especially if they have one that has a cable to connect to your tranny. Generally the things learners find most difficult is dealing with rudder and aileron reversal when the model is flying to wards you and setting up for a landing.Phoenix was a brand I remember as being good but I may be out of date on this. If you are thinking Spitfire in the future then buy a tranny with at least 8 channels 2 for aileron plus 1 each for rudder elevator motor retracts and flaps. A compatible 4 channel receiver will do fine for the trainer. Good choice on model and engine. Now about those bikes. I have some unhappy memories of RD 400s and LC 350s. On trackdays with my big Duke laid well over some spotty herbert on a stroker Yam would go past as if I was standing still quite ruining my self image as the next Foggy.

  3. I am a biker.these are hard to beat The Antrim coast road in Northern Island The A 537 to the Cat and Fiddle in the Peak District. NB This can be aggresively policed especially on Sundays. My favorite is the A470, Cardiff to Llandudno, Wales
  4. Test flight over long grass. Proper old school modelling indeed.
  5. Have had several bipes last being a 1/4 scale Stampe. It used 2 to 1 differential IE twice as much up aileron.
  6. Posted by Stuart Quinn-Harvie 1 on 06/05/2019 22:08:05: Evening all, I have seen a wonderful aerobatic thing performed by a funfly model. It was this: Aeroplane slows down into wind until pretty much stationary relative to ground, then ( I think ) all horizontal control surfaces go up and the aeroplane descends vertically whilst parallel to ground until surfaces re centr, engine opens up and it flies off. Anyone know what this is called and how it's done? Cheers All. Coupling barndoor ailerons with elevator to give large amounts of up can give very odd behavior. Put it on as a switchable mix engage the mix at least 3 mistakes high and have a helper on hand to switch out the mix if you are engaged.
  7. Posted by jeff2wings on 06/04/2019 19:56:12: So what happened to the original one to need a replacement ?I did a rebuild on one recently ,got the ring from gaviscool on e-bay Btw are you still in need of a Merco crankcase ? I don't know if you will want to fly the 148. I used a 148 in a 3D model flying the snot out of it for several years. Your 148 has the early carb which is known to have a poor mid range. The carb machined from bar stock with a better mid range. Ripmax gave me the new model carb on request. Once the engine was run in and the carb slow running needle was adjusted it was an extremely reliable engine. NB The slow running needle is very sensitive and needs to be adjusted in tiny steps.
  8. My boat came with 1/2 a gallon of West System resin and some slow and super slow hardener. We guys who live in the tropics do have some problems you know. It would have been 10 years old when I passed it on and still useable and set hard although the hardener was black. Some epoxies are very fussy about the mix ratio get it wrong and it never gets past the sticky chewing gum stage. A set of electronic scales are cheap as chips and enable you to get the mix crack on. TOP TIP 1 Make up a little chart which gives the matching weights eg assuming 5 to 1 then 7g hardener goes with 35 g resin TOP TIP 2 lay a sheet of cling film over the scales.Discard if it gets sticky and replace.
  9. Keep a close eye on the conrod You might find a spare on Ebay but an evening with a pillar drill some hard ali and a set of files will turn one out. Lots of info here The Mills story
  10. I have an allergic reaction to cyano fumes and epoxy vapors. I rigged up a simple extractor fan using tumble dryer extraction fan and hose. 15 quid from B&Q. The on the bench is loose so I can move it to where it does most good. Works for me.
  11. 2005 would be about right for a start date. When I last saw him at his workshop he had both wings complete and we did a trial fit of the joiners and that would be the summer of 2007. I am glad the Vulcan is still flying. It was marginal off grass but once airborne flew very nicely. Did Mick get his Hunter flying? I am blown away by the performance of these lecky fans.
  12. Keep posting here Chris. I would love to know if it flies. I helped out with some of the changes he made but I do not recall if he made the changes to a split wing, I know we did discuss this when he was in the planning stage and we both thought that split wing was the way to go purely to make it easier for him and Carol to handle. I know we did look at the possibility of a Royal B 17 kit and I think I tried to steer him away from this as he had a tendancy to build heavy. But there has been a lot of water under my keel since then and my memory may be playing tricks.
  13. I used big elastic bands for tension, wing retaining size, and well stretched. From memory 3 or 4 on the 36 inch bow and two on the 8 inch. Thinking about it today and it was 20 years ago I set them up, the tension should have been the same on both so same number of bands required but I definitely used more bands on the longbow. I was always a cut and shut measure by eyeball 'git her done' engineer. Edited By John Duncker on 11/03/2019 21:11:46
  14. If I was scheduled to fly on 737 max I would be canceling my ticket. Surely they need to be grounded till this is sorted Oh well 350 sold so maybe not. But if I go to SLC to ski this year both Southwest and American Airlines have the aircraft in their fleets.
  15. MDS 38 It was bought to power a Limbo dancer it's brothers powered a couple of helis. The Limbo Dancer spent a lot of time pretending to be a heli. The original towed Ripmax Trainer round the skies for years. It then was the only engine I held on to when Isold up on retirement and moved into an RV for a couple of years when we explored North America. I have no idea how many gallons of 5 % it consumed but it was a lot. Utterly reliable, almost always a first flick start and no messing around with the needle just two clicks richer in winter.After 12 years I sold it still on the original bearings.
