Thread: Aeromaster
28/11/2019 10:54:51

Hello all

I'm aiming to build an Aeromaster over the coming months (or maybe years, I'm not a fast builder). It's a classic 0.60 size biplane from 1966. It looks just like a full size single place homebuild bipe and reportedly has an lively flight performance.

The original kit version plan is on outerzone here

It's all very nice, but a bit complicated for me. I quite like my airframes a bit simpler. The original was geared up for a kit production and used locking tabs and so on. Wings are banded on. Lots of stringers and fiddly bits on the formers.

In 1978, a nice simplfied version was published in RCM - the Aeromistress. See plan here

That's all very nice, but a bit too much ply for me. I quite like my airframes a bit lighter. However, this version does follow the outline of the original quite faithfully, and adds a very neat cabane arrangement, whereby just one regular nylon bolt attaches the top wing.

In 1980, a scaled down version (from 48" down to 42" ) in 0.40 size was published in RCM - the Airmeister (see plan here).

I also have a Precedent BiFly - the smaller version - which, when I took a ruler to it, turns out to be remarkably close in size and shape to the Aeromaster, just scaled down from 48" to 36".

The Aeromistress, Airmeister and BiFly all capture the aerodynamics of the original Aeromaster,. I'm hoping my effort will do the same, and be a blend of the best bits (at least to me) of all of them.

The motor in question (or identical spec one) on Hobbyking:

3548 900kv propdrive v2

27/11/2019 14:37:06

I can confirm that 3548 (in my case a 900kV variant) is broadly equivalent to a 40 size glow, on either 12x6 or 11x8 prop, when using a 4 cell lipo.

My setup measures approx 800W freshly charged, and 700W at end-of-flight, using a 4S 5000mAh 20C lipo, and APC 11x8.

I use a higher pitch; mine is not in a trainer. In the Nova I would probably plump for a 12x6.

Stunning work Timo.

It will be a shame to cover up all that woodwork!

Thread: Foam Wing Cutter
27/11/2019 09:06:33

On another forum, the common practice seems now to be

veneer of choice (balsa, obechi, etc)

very thin spread of gorilla glue (or other foaming PU glue) on the veneer

line it all up

put the wing back into the offcuts and weight it all down for 24 hrs

disclaimer - I've never veneered a pair of foam wings

Clear Coat was great stuff.

No idea what I'm going to use in its place.

Build is looking good Tim.

That's the stuff.

Has no glue, I believe, you'd need to find something to paint the airframe with first.

Nope, mine are alive and kicking.

But I do need to get some four stroke power into the hangar.

"40 sized slab sided (no stringers!) constant chord low winger -- for for us Neanderthals, choice of nose or tail wheel"

You could try Pegasus kits, particularly Galaxy Magician / Hornet / Musketeer.

All slab side foam wing trad kits.

Oratex, iron on heat shrink.

Or, nylon with dope.

I'm sure there is an iron on fabric used by microlights that would work although the name of it escapes me, I have never used it personally.

"Yes they will be exempt - the rules and the code allow for anyone to fly outside the normal restrictions - for most of us it will be a polite no, but go with a compelling reason, as most commercial operators will be able to give (even if it is just money)."

Certified category, CAP 1789, comply with that and legitimately overfly habitation and close to people.

Certified for all the same reasons full size operations are certified, of course.

 

"All those BMFA members who rushed ahead (against advice) and registered already have un-necessarily paid for 3-4 months of worthless registration?"

If you paid the BMFA £9, you are not yet registered.

The BMFA registration will happen en masse on the 31st Jan.

 

Although as the exemption date changed, perhaps the BMFA registration date will also change to match.

"All the ones near me have closed despite the fact I used them a lot - obviously not enough people did the same."

Everyone started buying from Hobbyking* instead.

Logic sell a stepped reamer. 6, 7, 8 & 10mm. Right tool for the job. I've used one a few times - well worth it. I've tried drilling a couple of times and ended up with a paint stirrer. The reamer would have saved the wasted props.

 

Hope your hand is ok.

Maybe I missed something. But the most awkward bit in there for us is the 150m from housing rule. On this front I would anticipate the BMFA to lobby for continuity with the existing arrangement of 50m with our height exemption.

Everything else simply puts us in open category class A3 I think.

Our game aside this has the framework for certification of devices that could be used to overly cities. Which would not be a bad thing.

Only Jon knows, but two-in-a-row would presumably make a rather nice inline twin.

21/11/2019 13:21:50

It's an issue because people perceive it to be - once that fancy model is bought, the cost is mentally written off, and all that is considered is the ongoing cost.

Although I agree. Glow is simpler than petrol (I like simple) and methanol itself is not that pricey, so with low oil and low nitro (and I'm not sure if you have seen this yet Jon)

**LINK**

Weston quoting 7% oil 5% nitro and a big whole £12.72 (presuming you buy 4 gallons in a shot).

The 10% oil and 0% nitro flavour is under £10 a gallon.

 

PS no connection with Weston!

Thread: Hobby king delivery charges

A network of local post offices, none of which are used as collection points for missed deliveries.

Depots in towns miles away, open for a short time during office hours only.

Slow deliveries.

High charges.

Jobsworths refusing your parcel when you try and post anything that isn't a letter.

The post office, what a good idea.

I'm afraid I gave up on them a long time ago.

"flouting what is now law, just because I consider it unnecessary and futile in its effectiveness against malicious intent"

At the risk of repeating what has been said a huge number of times already, the prime intent is to support commercialisation of 400-1000ft region.
