Thanks Ken. I'd heard it was running slow but hadn't noticed.....and I have a different laptop so the thought was in my mind that this computer could be the problem.

Thread: The Aeromodeller returns!

Posted by kc on 16/05/2012 11:53:47:
There seems to be consolidation in the aeromodelling publishing world as ADH (Model Flyer )seem to have bought Aviation Modeller Int etc and say they are going to re-start Aeromodeller in late 2012. ( of course it was inside AMI for some years) Plus a new Electric magazine.
Is this good news or bad?

It all depends, make it interesting enough...... Currently I only subscribe to RCM&E. In the past I have subscribed to most but they have failed to hold my interest, that could be me though. I cancelled my subscription to RCMW and EFI years ago because of duplication of articles, I felt cheated. On top of that EFI combined with Silent Flight and then all but ignored those of us interested in gliding.

For my money I would still love to see a dedicated gliding mag.

A good experience. I ordered 2x 3300 3s 25c Lipo's at 3pm on Wednesday and they arrived on Friday morning. Priced at just under £25 each with £4.05 for First Class insured postage I thought it was good value and the service was goodthumbs up

Well, I ordered at around 3pm, 2 days ago and the parcel has arrived this morning, 1st Class, insured for £4.05, 2 batteries at a total of 600g.

I'm happy enoughsmiley

I ordered 2x Gens Ace Lipo's yesterday, didn't notice the change until PayPal checkout.

Postage seemed reasonable considering it covers packing and the increased postal charges. I opted for First Class at £4.05 which is insured but not tracked. The batteries are 3s, 3300mah 25c at £24.69 each. Gens Ace have good press and at that price I think good value. And no surprises regarding import duty or handling charges. I had looked at HK and ordering through their european warehouse but couldn't get what I wanted. Turnigy were the closest and cheaper but postage wiped out any saving.

Checked today and they have been despatched. Can't grumble so far.....

Besides when Traplet charge a tenner to post a planthumbs down

Thread: Throttle for height - elevator for speed

Martin

Sometimes the corrections required are actually quite large when flying an approach in gusting conditions, if the thrust is maintained whilst flying the glide slope speed changes of +or- 20 kts could be observed. I think the reason for flying pitch to maintain the glide slope is that it is a more instantaneous response. Think of it as flying down a cone, as the runway is approached the cone narrows and any correction has to be much more precise. The aircraft responds fairly quickly to pitch inputs, whereas a power change input takes somewhat longer (more so in a jet) to produce a result and at 200' that can be critical.

Just seen this. Confusing?

Think of it this way, elevator controls attitude, if the aircraft is fast on the approach, pitch up to slow the aircraft, that has the effect of reducing the rate of descent, the rate of descent is then balanced with power. Simple.

On a glider elevator is still used to control attitude but power cannot control the rate of descent that is what the airbrakes do. More airbrake for a greater rate of descent, as the brakes are opened the attitude will need to be reduced to maintain speed.

Except.....when flying a coupled approach, for example an airliner flying an ILS (instrument approach), pitch is used to maintain the glide slope and thus rate of descent, thrust is then used to control speed, this principle still applies when flying a visual approach in large aircraft.

Thread: all flying v tailplan/elevator
01/04/2012 09:11:31

Back in the 70's there was a glider called a Wildfleken by Radio Sailplanes. These could end up in a dive, particularly when high where it is impossible to judge the attitude of the glider, the model would tuck under and the elevator would become ineffective. This was thought initially to be an issue with the all moving tailplane, however it was found that at high speeds the wings were twisting, once that happened elevator authority was insufficient to recover.

Once I had a Multiplex Alpha glider that had a nasty tendancy when pushed to go quickly, the elevator would appear to become over sensitive, that was all moving. I used that wing section on an own design glider because it would stay up in the lightest of lift and fitted a conventional elevator, it showed the same characteristics at speed pointing to the cause being the wing section.

I have since flown many model gliders with all moving tails without problems, including an Alpina at high speed. I also flew the Robin DR400 Cadet for my PPL and have since towed with the 400 Regent, no issues at all using all moving tails. My only advice would to esure that there is no slop at all in the linkage and as mentioned in a previous post to pull for up elevator. Interestingly modern full size gliders use elevators.

Thread: How many engines have you got?
31/03/2012 13:26:37

I think I have 26 ranging from a sweet .4cc Mills to the superb in-line OS IL-300.

My glow engines are mainly 4 stroke, I have 7 diesel including a PAW .60, 3 Laser engines and 5 petrol.

Considering my passion is gliding I have more flying power models than gliderscrook

Good to hear of the maiden, I take it the Zen 26 was more than enough power for this 80 incher !

Yes, more than enough. At the end of the second flight the engine had probably had about 30 minutes running in total so I guess it is still tight.

30/03/2012 08:33:53

Finally I flew the Taylorcraft on Monday (26th). I hadn't flown since Jan 2nd, so out came the Stryker, Parkzone Spit and an electric CAP 232. I'd only flown the CAP a couple of times before and found it a little twitchy, worse this time, I was using a lighter battery and although I had checked the balance point it was definitely tail heavy and I was lucky to get it down intact.

Out came the Taylorcraft, I rigged it carefully, filled it with fuel. The engine fired up on the first attempt and after a warm up period I taxied out to the strip. Lined up I opened the throttle and off she went, slightly left wing down, a touch of right trim sorting that. Climbing to cruise altitude a fair amount of up elevator had to be trimmed in due to a significant nose down tendancy. Once in trim I could relax. I was keen to try a landing so lined up for the approach she settled at what appeared to be the correct speed, over the strip the throttle was brought back to idle and she touched down gently. The first flight lasted less than 4 minutes.

I had a second flight that day with a few basic aerobatics thrown in. A check of the stall resulted in a wing drop. A loop from level flight was effortless. She rolls rather well too. and the second landing was better than the first.

Up to now the largest models I had flown (other than 4m span gliders) were a Harrier 90 and an Acro Wot. This Taylorcraft is a gem, she is stable, the controls are well balanced, she is manoeuverable and she looks good. Not only that but to buy all the bits to make this model from a kit would cost more than the discounted price I paid.....and then it would take me ages to finish it.

Well done Hangar 9, you have a very impressed and happy owner.

"SO, has anyone actually repainted the canadian maple leaf emblem the right colour?"

Apparently there is some dispute as to the correct colour. The highly accurate and expensive. Tamiya 1/32 Spitfire IX includes both red and green maple leaf decals.

I've had a couple of dozen flights with mine and belly landing is no problem, the radiators are prone to collecting grass and mud but that's all. A cannon came off on an early flight but only because I hit the ground a bit hard with one wing down in poor light, bring it in wings level and hold it off don't fly it on and you'll be fine.

I couldn't resist getting one of these. Probably taking me a bit longer than some to put together (I've lost my workshop). A bit more work than the foamy BNF models. Had to attach the tail feathers and linkages, undercarriage and engine. The radio gear is already installed. The Zenoah 26 started easily enough today after bolting it in, first go for me with petrol.
It looks good, from all accounts flies well and at the price they are going for a bargain. A big car or van is required for transport though.
I'm looking forward to flying it.
Anyone else with one?

Thread: ParkZone Spitfire Mk IX
01/10/2011 07:44:25
I've been trying to get back into flying for a while, I still build, read and buy but just don't seem to have the motivation to fly......until now.....
I bought a new Stryker from the Nats......not been able to fly it much but it stays in the car just in case......so what's this got to do with the Spitfire? HA,ha, so impressed was I with this BNF foam concept that I have just ordered the MkIX BNF for only a few quid more that Tamiya's 1/32 MkIX plastic kit (??? work that one out???).
My reasons for buying this Spit are that I had a couple of 3s lipos of the correct size, bought ages ago for an o/d that has flown on nicads but never used, I have a new lipo from the Stryker so for the moment I have a "standard" battery size that will actually now fit 4 models. Where I can fly is not suitable for retracts, the model is a car friendly size so will stay in there with the Stryker and still leave room for the dog....... And lastly there are some cracking deals around......oh yes, I just love the Spitfire.
Being a "traditional" modeller, yes I've built from plans and really enjoy the construction process, foam, other than in wings, has never had a serious attraction until now.
Hopefully my Spitfire will be waiting for me when I return from work on Tuesday night and fly it on Wednesday.

I do remember a build series by Rob Millinship (sorry if I've spelt his name wrong). It was a Spitfire, Mk IX I think but don't know whose design. Not even sure if it was in RCM&E.
At least 10 years ago probably more.
Hope that helps.
