It is, Peter, a miniature live steam railway. Over the years I've come down from large road going traction engine, through ride on Locomotives, settling on Gauge 1. I make my own, and have provided livery services worldwide; museum quality5 points

The Hawker Sea Hawk always was a very elegant jet. By bifurcating both the inlet and exhaust Sidney Camm was able to install substantial fuel tanks either side of the rather portly RR Nene in an era when jets suffered short range and endurance compared to the previous generation of piston powered planes. Due to its size and weight it lacked performance so the RAF rejected it (the Meteor was faster) however the Navy liked its duration and load carrying ability so was ordered into production. It only had a short service career as the much more capable De Havilland Sea Vixen soon appeared. I am electing to use the rather soft 5 mm underlay foam as it is all I have access to in quantity! A fully bifurcated EDF is always a challenge. The ducting becomes the heart of the plane as the rest of the airframe is pleasantly simple and aerodynamically efficient. When I built my Folland Gnat I printed the entire duct and then built the airframe around it. The shoulder mounted wing meantthere was no issue with the spar crossing the duct. This will certainly not be the case with the Sea Hawk where its spar will have to go round the EDF. ☹️. On the plus side the Sea Hawk duct although a fairly complex shape will be short so keeping the weight down. First a half size test print of the exhaust duct. You can see why it was nicknamed "the trousers" at the Factory. Next to try to print it twice the size and to the exact dimensions to fit the plane.3 points

Hold your horses guy's ! Here i am , and i'm here to stay ! I know it's been a while sinds i posted here but i had (have) a lot on my mind lately... My doughter is moving into our old house wich is being renovated completely at the moment so she's back living at hotel mama with her partner. Besides that , my (so very much needed) hydraulic car lift broke down and no parts are availeble (1976)so i had to repair it myself. The link between el. motor and hydraulic pump was completely worn out .I had to weld up and re-form the pump shaft and the el.motor shaft. Al went well and we're back in business ! This all out of the way , allows me to go on with the magister. The last month i was busy with the panel lines and dummy screws , primered the fuse with hatches , and finally got her in painted ! I must say , she's looking good !! x x x3 points

I have been playing around with the installation of the radio, trying to get it all in, and on or around, the C of G. With the control rods added, and the tail wheel, and the main wheels, it would seem to be balancing on the mark. I also spent some time re-acquainting myself with my Radio-Link AT102 Tx The tiny little Rx worked OK. Two more arrived from Banggood today. Tenner each. Every thing is attached now and functioning as it should, The wing will be glued on, so it will be a trauma to get to the radio if it should fail, but Hey Ho if it goes in, it will be a mess anyway. D.D. Couple of shots of the old school Control rods. The little RX on its pad, to be fixed later.2 points

Hi Robert, just come across your build, looks really nice. I liked the look of the Sunderland, so at the start of the first lockdown sent for one and began to build during the lockdown. Here are a couple of photos of my finished one.2 points

This is how it should be. Covering next but what colours. White and Blue are my favourites at the moment so I will go with that. Cheers2 points

For a bit of fun I extracted the sound only from another one of the vids I took during the last flying session - great with sound up and multiple speakers! Eat your hearts out leccy flyers!!!!! Sound1.wav2 points

I'm not a DX9 user, but I have helped other people with theirs and experienced this before. Try looking at timer settings. I suspect the peeping is the throttle based timer starting and stopping. I think that the peeping can be turned off. Alternatively, enable the One Time feature so that the timer beeps once when timer starts as throttle first raised and then keeps running regardless of throttle position. See here:1 point

And hopefully I now have a set of matched ribs. No more today. Birthday tomorrow so an evening of wine and fine food with SWMBO.1 point

Tosh, as a matter of interest do you fly IC or electric? When I took up flying electric I could not easily tell if I had too much or too little power set when flying straight and level between aerobatic manoeuvres. I use a peep at half throttle on my Tx as it marks the standard power setting for when I'm flying straight and level with an electric powered aircraft. With ic you have the noise of the engine to let you know your power setting so don't really need this. If half throttle is too low, why not set it to the power setting you use for S&L flying and use the facility on the Tx to help you fly more accurately? Just a thought.1 point

I've had a long association with "wonderful" Amy since a fellow member built one about 17 or 18 years ago and I was the only one brave (foolish?) enough to step up to maiden her. I set what I thought was an appropriate amount of reflex and with some trepidation, set out to the flightline. She flew hands off with not a click of trim. I flew her a lot for the owner who was a builder rather than a flyer and, with an appropriate C of G, she will do pretty much anything asked of a conventional aerobatic model. Watch the C of G though - a little forward of the plan position will give you a good starting point although it is now ballasted to around an inch and a quarter behind the leading edge. At this point she spins and flicks like a top - usually on command but she will bite if provoked - watch out for an inadvertent flick from a recovery if you venture back... During some of the earlier flights, while getting her set up, it seemed that if anyone ever remarked on how well she flew, she'd immediately do something nasty so we used to make a standing joke of telling everyone what a horrible model she was to fly, while I enjoyed myself immensely! Amy flies very well on a 25 FP (with a 9 x 6 APC) so that's a great choice - you might find her easier with slightly less pitch at first. Mine is such a sweet engine. Mine? Well when the builder gave up model aircraft for boats, he offered me Amy for a nominal sum and I virtually snapped his hand off!1 point

As Amy was a plan feature and not a free one, I hunted high and low for a copy of the plan. Thanks to a very kind member of this forum I am now in posesion of a perfectly usable copy of the plan. First thing to do was to scan the magazine, I like to keep a copy of the build instructions handy. Next thing to consider, which engine? I have two to chose from, an OS25FP or an SC25. The original flew with the OS so I think that would be the logical choice. Next thing to do? Copy the root and tip templates onto some ply and make a set of ribs. Sandwich method so I may be gone some time.1 point

Thanks again, John. I suspect RB bought some sandbags for FP2, probably some second hand ones from Toto... Cheers & good luck all Chris1 point

Just remember, these modern plated plugs don’t stand up to abuse. I think they don’t like: being left wet being run on too many amps off the starter power supply revved with the starter power supply on. All of the above leave a matt white plug coil, and the motor does not want to tickover reliably.1 point

Seems that you were just unlucky John and possibly just a slightly iffy batch that slipped through Chinese quality control on a Friday evening? Certainly not blaming Rapid RC Models as they are a top company and I have bought lots of items from them at the shows. Phew ?1 point

I could look at the newley painted parts for hours but no time to waste now ! I started to make the parting boards , beginning with the nose cone. The rest will follow next days and will post as much as i can so stay tuned once more ! For minimum risque i will make the nose cone in two parts , as this is easyer for de-moulding1 point

Hi Guys, Well putting the ideas into practice was fun today. Bottom line is I can now perform what would pass as a stall turn! A crosswind did not help as it would only turn one way. So straight and level fed in the power up into wind did not take the throttle down much and before it stopped blipped the throttle as I put in full rudder and over she went. Horah! As for the sudo tick over, I always have the prop turning a little as it helps slow the approach especially if the wind is light. As stated you can also tell if the kill switch and failsafe are working. Thanks for the advice chaps Charlie1 point

More covering today, got some of the new tissue on the tail feathers etc, What a revelation it is to use the wet strength stuff, what can I say, you can pull it around, lift it, and generally mess about till it's right, with no rips or tears or crinkles. Cosmic !! D.D. I have left the Laminating film uncovered where the side windows are, to save having to glaze them. Picture does not show it very well, I will attempt another one. All tissued up.1 point

Here is a youtube video of the Laser inline twin flying in my Acrowot XL on Wednesday - good friend Phil Jarman filmed it with his phone! It was a very blustery, cold day, you can hear the wind (and not much else, sadly) in the background. Steve.1 point

Very nice one there Eric, perhaps avoid a overcast or dull day with that camouflage it will be very effective. Flair DR1 with Laser 150 maiden today. Best described as a mature model with at least 2 previous owners. Flies very well and needs me to catch up with the ground handling traits to get the best out of it.1 point

Not new, built last year but due to lockdown had it's maiden flight today flew very well.1 point

Its virtually finished. Just a couple of touch up jobs. And it all works! In deference to the rather more flexible foam used in the forward fuselage half the wing is now glued into position rather than held with 3 nylon bolts as previously. Rigidly closing off the fuselage underside adds significantly to both its bending and torsional rigidity. If anything the slightly reduced span has improved the appearance giving a more compact look, well I would say that wouldn't I! ? My apologies to Peter Miller for emasculating even further his original Ballerina design. ? It was not just my 'stingy' nature that drove me to restore it but the importance to me of its horn free and closely shrouded aileron system. This was the first time I had attempted to do this in Depron. Not that it would make the slightest difference to the performance of this plane but the technique was used on the Endurance where the aim was to achieve level flight using just 11 W/lb. A plane with aerodynamics where, to miss quote the Tesco slogan, "every little really does help".1 point

Re-maiden it today and if anything it was much worse resulting and in a massive prop hanging moment over the wood followed by getting stuck is a very tall tree. With significant poking it fell its last 30 ft out of the tree. Autopsy tomorrow, but I think little will be gleamed form the pile of bits.0 points

I have test flown models for other people a number of times. On at least two occasions, when I have done the fail-safe test the engine has revved up to full throttle rather than cutting. Thank goodness for model restraints is all I can say! The cause of this was a simple mistake. Binding with the throttle channel initially reversed, then reversing the channel to correct it, but failing to rebind in order to reset the failsafe. On the other hand, I once almost had a very nasty accident due to use of a large version of the type of restraint linked in the second post. I had been doing some work on the tail wheel of "Dusty" as per my Avatar image, with the tailplane resting on top of the restraint to allow the tail wheel to dangle in mid air. Some time later, it was time to have a fly, so I flicked the DLE55 into life, the model moved slowly forwards, but instead of being restrained, the tail dropped off the restraint. The spinning propeller was now heading directly towards me! I managed to jump backwards without instinctively putting my hand in the prop and finished up in a sitting position with the propeller heading towards my meat and two veg! I managed to get one foot onto one wing's leading edge and the other foot on the other. My manhood was safe but there was a problem. I couldn't quite reach the transmitter because I had jumped backwards away from it. All I could do was shout for a fellow modeller to pass me my tranny (or wait for it to run out of fuel), so that I could hit the kill switch. A day I wont forget I can tell you.0 points
