Thread: New limit on groups in England from Monday?
14/09/2020 06:04:15

All our members have an email. It’s been a slow process but all now use email to contact me if they need a flying slot.

There are two sessions on a Wednesday and Saturday that members book in, 6 slots in each session. I than put the names on a special page on the club Website. All can see if the session is full.

All booking emails are kept only by myself and deleted after 21 days. Any cancellations are amended on the page. Once a session is full an email goes out to all members.

I’ve got them rewards at the moment

Brian and I had a discussion about those.

Do we leave them that way to push/ scoop air into the engine bay and hot escapes out of the top near the exhaust?

Or do we have them turned around so as they create a drawing effect, pulling air in from the front and out the louvers?

Any thoughts and options

As far as I understand it, team competitive sports has to pass a number of tests. A written risk a

assesment needs to be done and a policy document drawn up. This then needs to be scrutinized by the relevent governing body before being signed off.

No change for us. We were just about to discuss the possibility of increasing the flying slots to 8. This now won’t happen.

oh well, back to checking booking emails.

There are several ways. The total distance from the LE top wing to the TE lower wing, that's the total wing chord. There are lots of sites.....just type in RC biplane CG calculator

The graduate with a Science degree asks, "Why does it work?"

The graduate with an Engineering degree asks, "How does it work?"

The graduate with a Commerce degree asks, "How much will it cost?"

The graduate with an Arts degree asks, "Do you want fries with that?


Two engineers were standing at the base of a flagpole, looking at its top. A woman walked by and asked what they were doing

"We're supposed to find the height of this flagpole," said Sven, "but we don't have a ladder."

The woman took a spanner from her purse, loosened a couple of bolts, and laid the pole down on the ground. Then she took a tape measure from her purse, took a measurement, announced, "6.5 metres," and walked away.

One engineer shook his head and laughed, "A lot of good that does us. We ask for the height and she gives us the length!"

I run inverted two stroke engines on a four stroke OS F plug.

Always works for me.


Thanks Maury, I’ll bear that one in mind.

I’ve been told the same. As the OSf plugs are deeper the fuel that could “pool” does this below the filament.

I would embed in foam and hot glue some to the face of the tank.

Is the back plate on tight? At any rate strip it all down and check the inside, new OS f plug. If you have an engine test bench, see if it will fit inverted and try and replicate the poor running on that. Is there anything blocking the pressure nipple?

Nice install and idea, however I still have a couple of nagging thoughts

One TX, with one battery and set of electronics transmitting

One frequency range - if someone screws around with 2.4 there is no alternative frequency the TX and RX are running on at that time.

But by the far the bigger issue for me is if you fail one RX I personally don't think I could fly a model with the remaining controls. If the RX fails with controls neutral perhaps then just direct it to a crash site, but say a RX battery fails and you have a fair bit of control stick in then I really am not sure.

Anyone flow a model and "landed it" with port aileron, starboard elevator, rudder, or stb aileron, port elevator, throttle?

Still not convinced about duplicating complexity and maintaining reliability. I can see the logic with isolating unreliable components (UC stalling) from critical flight controls, but having two very reliable devices (RX's) sharing critical tasks just increases (IMHO) the chance of failure?

What do the LMA guys do?

That’s exactly what the LMA guys do

Off to paint today. I’ve not posted much as there is not much to see. We’ve used flat stainless steel rigging wire and bolt through clevises. The thread ends silver soldered onto the wire. This has taken nearly 3 days over various weekends and afternoons. All will be revealed soon...

I spent 2 1/2 hrs yesterday getting all the surfaces level and dialled in to the Tx . There is twice aileron differential. The suggestions of throws are all done. It’s going to have 2k NATO Matt green and Matt sand.

Excellent idea!

Wood ( can you see what I did ) the ball end get worn and loose over time? I assume it’s hard wood that’s been used.

Just gone down the twin Rx set up for a biplane. It’s a twin switch/ charging socket, twin batteries and the controls are split in half between both RXs

1 Rx has port aileron, starboard elevator, rudder, opts isolator. 2 Rx has stb aileron, port elevator, throttle.

Simple, gives redundancy and cheaper than a power box switch
