Thread: Wing bag and hanger

Have you tried the wing bags from Hobby King? They are amazing value and can be hung up if you want. I made some wing bags with the radiator foil stuff and they are not as robust as the HK bags and have space for wing joiner tubes and, if you take them off, tail planes as well. £15 for a bag where it would cost £30 just to buy the zips in the UK is amazing value. Just my 2 pennorth!

+1 👍

Another vote for the HobbyKing wing bags! Very sturdy and protective.

Thread: Great Model Railway Challenge
07/10/2018 17:11:08

Well I quite enjoyed it. It is meant to be a general interest tv show, rather than a specialist show for modellers. Obviously the enthusiasts all worked hard on their layouts. Nice touch with the Spitfire and parachutists.

Worst thing was having to include a ladies shoe in the layout. That said, a couple of the teams even managed to do something sensible with that! Us modellers are a creative and enterprising lot.

If it is 70" span it could be from a Complete-a-Pac kit or plan? I never had one so it's just a guess.

Thread: Can't fly - there's something on the runway!

Wow! That must be very expensive!

Well yes. But the (French) club has been awarded a grant by the national aeromodelling association and the local authority persuaded a local earthworks contractor to do the job at a special price as a goodwill gesture. It was done in a "gap" between other jobs I believe.

Went to the flying field this morning for the first time in ages. Couldn't fly as there was something very big on the runway. No one told me the contractors were going to be there putting in the foundations for the new runway today!

This method works well for me.You tube video shows how on an XG8.


Thread: Flaps
18/08/2018 13:39:07

Flaps make most models more versatile and fun. My favourite is my "old" Great Planes 82" span PT-19. It didn't come with flaps but I added some inset flaps to the wing underside. Scale size, shape and position. They really transformed a nice model into a great one. A favourite occupation with the PT is take off and fly at full throttle and max climb until the end of the downwind leg. (Idea is to get as high as possible) Then cut the engine to tickover, apply full flap and adjust the descent with elevator so as to arrive at the runway ready for a touch and go then go round again! It's amazing how steep a descent and how much height one can lose with flaps!

Worth noting the model has lots of wing area and is lightly loaded. Maybe not something to attempt with a highly loaded brick!

Thread: 1:5 Spitfire Balsa Kit - Custom Control Horn Design: Length?
13/08/2018 13:35:26

spitfire elevator.jpgJust a thought. Is the elevator hinge point really where you show it in the diagram? Aren't they normally hinged at the centre of the circle that forms the radiused leading edge, rather than at the leading edge itself? If so, that would affect the geometry of your diagram.

Thread: ASP 120 or Saito 125 four stroke
12/08/2018 16:42:03

Definitely go for the Saito if you can. They are, as others have said, really in a different class to the Chinese "copies"

Thread: 35mhz; 40mhz; or 72mhz best for electric model
11/08/2018 20:34:22

Geoff, reason for contemplating using old tech gear is because I have a "spare" radio that might/could be left in France with the model for when I'm there. If it is not viable to use the old FM set I will need to use my 2.4 radio and take it with me.

11/08/2018 18:00:17

I know what specific frequencies are legal in France. I am wondering which of 35; 40 or 72mhz will work be most robust in an electric model.

11/08/2018 16:43:04

A question for the electronics experts out there. I am thinking of equipping a small electric model for use in France. Over there 35mhz, 40mhz and 72mhz frequencies are legal. I have tx modules& receivers for all 3 bands. Which band (in a technical sense) would theoretically be the least troubled by potential RF/electrical interference from the motor/esc?

Anyone have any 1st hand experience of using 72mhz with electric models?

Thread: Sound Test Certificate.
23/07/2018 05:58:35

Would a certificate be worth the paper it was printed on? A noise test only measures the sound at that one moment in time. If the fuel or prop or plug is changed, then so can the revs and noise level.

Thread: Do servos have a use by date?
14/07/2018 06:23:47

Well, I have several standard-size JR servos (Coreless motors and made in Japan) from the 1990s still working perfectly in models after nearly 25+ years. I also have a Tundra RTF electric model from Hobby King and 4 of the pre-installed 9g servos (made in China, with no maker label) failed within 2 years.

So I guess it depends on the quality, size, use etc.

Thread: Where are all the 120 four stroke gone ?
28/06/2018 07:39:11

Saito engines are excellent. I've not needed spares as none of mine have gone wrong or worn out. All the 125 Saitos I have seen have been great runners, light and powerful.

That said Laser are great engines and I love my OS Gemini 160 twin too!

Thread: Exhaust thread worn out

Have you tried wrapping the exhaust pipe thread with PTFE tape before you screw it into the head and tighten the nut? Might be enough to keep you flying for a while.

Thread: Veron Hawker Tomit refurb.
11/06/2018 11:32:45

Chas, I also used chrome Profilm. I put mine on top of the Solartex on the fuselage side panels. The weave of the tex fabric didn't show through the Profilm, so it was just the easiest to do. Also a double layer of protection from the exhaust oil. On the cowl I just used the Profilm. I cut panels and managed to get it to form around the double curvature pretty easily. I even managed to cover the cowl blisters without too much of a problem. I did fuel-proofed the seams on the cowl.

Thread: Difference between 2.4 module and 2.4 tx.
10/06/2018 19:27:27

Just to be clear, all my receivers are genuine JR DMSS models except the one orange "copy". So my question is one of technical interest rather than penny-pinching. Was really wondering if there was a difference in the way tx modules and built-in transmitter units worked. Could it be to do with the fact that plug-in modules use PPM input whereas XG transmitters use a different "input"?
