Thread: UK leaving EASA!
10/03/2020 11:16:15

I think if a homebuilt sub-250g model is faster than ~30mph it will fall under the Open A3 category (if it was slower it would be Open A1), which is where anything homebuilt heavier than 250g will operate anyway, so I don't think it's that big of a deal, you just have to be a bit more careful about not overflying people.

I'm going to pass on the question about javelins, discuses (discii?), etc. :D

link to EASA "Easy Access Rules for Unmanned Aircraft Systems" document:


I'm not sure "Easy" would be my description, but anyway.

if we're not going to adopt/align with the EASA rules, then the danger might be that we end up with the US FAA rules, which appear significantly more draconian & restrictive.

can you hook up a pump to spurt oil out of the exhaust & down the side of the model? wink

Thanks for the complete artistic impression.....Hello Andyh ,if I could ... would not miss it face 1

nothing to do with me I'm afraid, it just popped up on my YouTube feed & I thought I would share it here

I do know a bit about ATOS though as I used to fly hang gliders. ATOS make very well-regarded composite hang-gliders & micro-lights, & the wing in the video looks very much like it's from one of their hang-gliders.

In the decades I've been involved in the hobby I've seen very few youngsters come into it.

it's my impression that the hobby is currently attracting more new young beginners than for many years - perhaps even since its heyday in the 50's - it's just that they're building & flying quads rather than planes.

it may not be balsa bashing & tinkering with oily engines as was the new thing back then, but I doubt 50's kids were very interested in 1890's technology - certainly not 1890's aviation technology!

times change*, technology moves on & the hobby adapts, but I think the fascination with flight will always be with us.

* I wouldn't recommend trying to buy a pint of ether in Boots these days.

I don't think it's the flying which scares the long time builder, it's the leaving of the ground for the first time.

leaving the ground is no problem, it's rejoining the ground that's the issue!

Andy H

I have been using those sections for quite a long time now. They are thick enough for my liking but are flat bottomed from the spar back for easy building.

They are not really thick. Clark Y is 12% and that is a bit thin for aerobatics as far as I am concerned.

I am sure that many experts will have a different opinion and probably righlty so. I just use what works for me and it does seem to work well.

NACA 1424 & 1434 have 24% & 34% thicknesses respectively. I suspect you meant 3413/3414.

Posted by Peter Miller on 20/10/2018 08:49:39:

I also use NACA 1424 or NACA 1434 sections.

if my understanding of NACA airfoils is correct, those sound a tad on the thick side!

has the Miller TLAR section fallen out of favour?

What I cannot comprehend is that people will post directly the opposite to what George advises about his products in this forum.

I think LiPo's are a sufficiently generic product that other people are entitled to an opinion based on their own experience of using essentially identical products.

another vote here for parallel batteries feeding both ESC's (& both uBECs), so long as they're well matched I don't think you'll have any issues.

one other thing to note, I see on your diagram that you've disconnected the +ve red wire on the "trunk" of the Y-lead from the Rx to the ESC's as you're using a uBEC. personally, I would (& do) disconnect the red wires on the two "branches" of the Y such that the two ESC +ve's aren't connected, rather than on the "trunk".

Was able to reset password and log in; looks ok, but no capacity to renew online at this point that I can see. I guess that will be enabled in Nov/Dec.

the next year's subs don't get set until the AGM in Nov each year, so renewals aren't possible until after then.

Unfortunately the portal club finder has lost all the clubs in Yorkshire!

Andy - could you look at what the portal says is within 50 miles of Leeds / Bradford, and compare it with the old club finder - the difference is in double figures...

I had the same problem - the geographic search seems to be missing a lot of clubs. I was able to find my other clubs by selecting "All Clubs" in the "within XX miles" drop-down.

Again, apologies for saying it but I imagine most people whom go to HK do so with the aim of making a saving. This is one example of Hobbyking ending up ironically costing someone unnecessary cash........

you'll have a tough time buying a Tundra from anyone but HobbyKing Percy

find yourself a 3536 motor of 850-950kV rated at somewhere close to 40A & your Tundra will fly much better! something like this:


sorry, my mistake, don't order that one, the current rating isn't high enough. what Stevan mentioned would work fine.

Somebody (andyh I think) asked earlier whether club admins should now start adding their members whose BMFA membership is with other clubs. Any guidance, Andy S?

AndyS replied to me in email, so I hope he won't mind me quoting it here:

"A mixture of both [admins & members adding non-primary members/clubs] is good, both ways require approval from the other party, you will need the members date of birth and either their membership number or email address to add them to your club list. They then receive an email with a link to confirm they are a member and happy to share their data with you. If they add themselves to your club you will also receive notification and have to approve them as a member."

Thread: Foamies for beginners?
06/10/2018 17:56:21

people learn in different ways. some benefit from starting on something easy & non-intimidating with a gentler learning curve. others are better off with a "thrown in at the deep end" approach. I fall into the former camp BTW.

so long as trainees are given some assistance when making a step up to a larger/heavier model, I don't really see a problem.

I think that if small foamies are getting people into the hobby who otherwise wouldn't, then the positives outweigh any negatives.

Clicking on 'club profile' greys the screen and brings up an 'args is undefined' box with the option to OK this. Teething troubles I suppose, will take a while to settle down.

I had that too. mail admin@ & Andy will sort it for you.

Thread: Hobbyking Tundra motor
06/10/2018 15:54:36

are you using the standard 12x6 prop? if so, I'm surprised you haven't melted your motor!

your 2836 motor isn't rated for anything like the current/power of the standard 3636 - 23A for the 2836 vs. ~40A for the 3636 - so I'm not surprised you're down on performance. I'm assuming you have at least a 40A ESC?

find yourself a 3536 motor of 850-950kV rated at somewhere close to 40A & your Tundra will fly much better! something like this:


(I've linked to the EU warehouse as the UK one seems to be out of stock of all useful 3536's at the moment)

I love my Tundra, so it's well worth getting yours flying right!
