I never use flap either, can't remember when I did last, just keep full power, don't pull up off the ground too soon and not pull up either after take off - let the speed build up before doing so.

I've seen people come a cropper, by hauling their plane, especially warbirds too soon and see it tip stall, with obvious results!

Easy. Just cut 26mm of servo wire, remove the broken bit from the PCB with a soldering iron then solder the new parts to it.

That won't work, the wire is a Co-ax not a normal wire, and the gain will be altered - therefore range. Also on the long wire on the 610,there is a amplified section on it. Unless you mean the wire was damaged after the BODA aerial, and not on the receiver PCB.

The guy who flew the models at Greenacres, Richard Ginger is a very good scale flyer, and flew the models how they should - anyone who knows him can vouch for that.

Still, he had two engines fail. You're probably right, it is not the fuel, but the ignition system causing a backfire in one cylinder, think it was the 2nd cylinder that failed twice in a row.

I know Richard who flies at the Greenacres fly-ins, has had 2 Saito 3 cylinder radials blow up, with one cylinder giving up. Seems a common problem with Saito petrol radials, where the glow, far as i know not heard of any problems.

maybe not enough lubrication getting into that one cylinder..?

Thread: Boeing 737 Max 8

The White House has issued an emergency action, over-riding the FAA thereby grounding all US based aircraft. A worldwide ban on the a/c in now in force, even the Max 9 variants.

I don't think the public would feel confident using the aircraft at the moment, without the reasons why this horrible accident and loss of life occurred, and recommendations from the NTSB and accident bodies.

Probably the Lead Investigator currently investigating the Air Lion crash has another crash to solve, as the two incidents are similiar, and as happened before, maybe either crash might give a picture of both.

I will take a couple of years before the full report will come out, so, at the moment, it's speculation, although some recommendations on an interim report has been released regarding addressing wrong cockpit readings.

A 737 Max 8 has crashed, apparently, the same problems as the Lion Air one, the aircraft climbed erratically before crashing.

Is there a problem with the 737 Max 8m, considering the aircraft crashed was still new, only 4 months old.

OS 120FS Pump. Have quite a few of them and powerfull sound nice and keep going. One has been in 2 arframes and had 100's of flights, and replaced the bearings a few years ago.

Er, Paul, if you move the C of G rearward, I think you might need a lighter engine, or weight at the back end.

No, I am right, by the swept wing, the cofg will move rearward, so you need more weight on the front end to balance.

You measure cofg at the fuselage, not the wing; Think about it...

Landing an EDF is different, you need to keep power on and not shut it down, which causes excessive loss of height and multiple bounces. To land properly, drop the power off, get lower enough not to get too low and use the power to control the descent, so when touching down, it is a controlled landing, not a arrival.

Watch how full-size jets land. (notice how the pilot alters the power to stretch the glide and throttles off on touchdown.

You modify the wing yourself to make the swept wing. If you build it out of the box, you'll get the straight wing...

Not sure if there is an advantage, maybe at higher speeds and the would allow a heavier engine to be used on the swept wing, as it would move the cofg back a little.

Known problem - FX's were known for quality issues and having too thin coating on the liner wearing out.

Just engines did a replacement Piston/Liner Assembly, and not sure if they still do. I did a thread a while back, and these are the pics from a OS 10Fp/Rn which went the same way...

What can you get for £10? Apparently, I bought this trainer for £1, a £5 Hitec 2.4rx and battery for total of £10! Flew it today, the engine ran perfectly, as it's probably not ran for years - a mk1 SC40 2 stroke.

I have a PZ Spitfire, or rather a Frankenfire - made from 3 crashed PZ Spits, to make a good working one - then to take it further, as had no electric motors for it, fitted an IC engine.

At least it looks the part and actually works!"

The rear bit is off a spit someone crashed at Weston Park years ago - gave me the servos still in the wing and remainder of the rear fuz, Chris donated the missing front end and covers, and a few bits I found somewhere.

Still have a genuine one, electric....

This has been for sale for a while, no takers. For £180...

It's a T-28 Trojan fuselage on a Ripmax Bullet wing, even though it doesn't fit!

Good grief!!!

Not sure, got it half built - still need an engine for it. As regards batteries, they are all checked and replaced as of when.

I am genuinely intrigued by this revelation. Where on earth do you find space to store 500 models? What size range does your model collection encompass?

Anything from indoor foamies to 120cc aerobatic, and scale, warbird, etc in-between. Suppose some models have got the rx board built-in, such as Eflight/Parkzone models with a DSM rx board.

Have a look at my album to see. It would be confusing having to keep juggling a few rx's like this.
