looking nice much neater than mine.

Thread: Hot wire Foam Cutter question

Results look really good

My hands never seemed steady enough lol. Found the swing arm thingy/approach really good

good to know about the grey foam board from Bluefoam - may try and get some of this - looks like extruded polystyrene (?) which I have found difficult to get.

Lovely build, fuselage and wing saddle look great. Simple carbon reinforcement really appealing. But how did you get the white foam carved so well? When I've tried it, the white EPS beads go everywhere and ruin the surface.

@MikeT - I like the slugs - very posh

I used a very similar ballast tube to MikeT. But mine can't take as much weight. It uses 20mm conduit which will take 520g - this is enough for mine, but I was focussing on a very light model. It will easily outfly most other slopers in light wind and in 10 mph will go up fast. However, as you'd expect it's slower than a mouldie and so will not roll as fast as a 2.5m Blade for instance.

PS make sure you get rid of the release agent from the inside of the fus. otherwise the ballast will free itself on landing as mine did a while back.

I just varnished mine as well. I had to free up the hinges a bit to get the travel I wanted. Quite easy but you have to be very patient & careful otherwise you can put a score across the wing :O. I used 3 coats Eze-Kote.

I'd experiment with the West/glass combo on scrap balsa first to see how easy it is to score through - I remember it being quite tough, but I think mine was 10 years old and had thickened up a bit. You should be able to get through 20g glass quite easily as long as you use minimum epoxy i.e. about the same weight as the glass or a little over. I have put 25g glass on with Eze-Kote on a PSS model - works well but not as tough as epoxy. I'm pretty confident (gulp, I think!) that I will get be able to score through the glass/veneer & down to the kevlar hinge - but Easy-Kote goes on really thin.

I left the wings natural, but added sign-writers vinyl for orientation.

Thread: Radiomaster TX16s Anyone tried one?
27/09/2020 21:40:40

Bought tx16s last week as instant backup to my x9d+, as using the clone facility I don't have to rebind my receivers - brilliant feature.

I've copied my models across and tested 2, so far and they seem to work fine. I like the feel and handling of the tx16s so think I will make it my main radio.

Extra trims T5, T6, look great for things like butterfly compensation etc.

Mike

Just spotted this thread,

I love these models. I've had a hammer for about 3 years now and it's always the one I take up the slope as it flies in such a wide range of wind conditions - from 5-10 mph up to 35. Good to fit a ballast tube though as they are such light models.

I use same servos as you in wings with M2 threaded rod with plastic clevis on both ends (I find that I can't seem to fit z-bend arrangement without getting a bit of slop in the linkage).

Happy building.

Thread: Hot wire Foam Cutter question

Yes - I had same problem as MattyB with alu sheet.

10/05/2017 16:59:54

I have used printed circuit board from maplins - bit expensive and only as big as 300mm but easy to get. I've tried aluminium insulating tape over cardboard - works ok for first few but easy to damage. Someone said that they use Pertinax / Phenolic Sheet 0.5mm on RCgroups I think - this looks easy to cut and long lasting so may try this next time.

I think PCB used to be made out of paxolin - but has been banned as the dust is carcinogenic.

>Hmmm... just looked up dust from cutting Phenolic Sheet --- is also carcinogenic. >

Hmmm... may go back to aluminium.

Fantastic

I kind of like the look of canopy plug, as is nerd

Quite menacing robot adaptation sort of thing going on.

Not so aerodynamic at present though smile o lol

28/07/2016 22:22:31

Thanks Andy, sounds like a good compromise - must admit that when I saw the angle on scale drawings I thought that it would be really weird on a slope plane. Didn't realise original had a symmetrical section - makes sense now.

Mike

Andy, great looking build - am jealous of the quality of construction and the way you manage to keep the balsa ding free.

Also curious - looking at scale drawings and pictures it looks as if the real thing has a positive angle of attack of 3 degrees or so on the wing compared with the fuselage attitude. i.e. the fus looks nose down compared with the wing. Is this the case, and did you reproduce this, or go for a more conservative angle?

Really neat wing root solution Whole build makes me very tempted to have a go at one.

Thread: Hot wire Foam Cutter question
10/08/2015 19:45:05

Paul,

I do use nichrome wire and found it to work fine - I must be doing something from MattyB so I'll give details:

I use 1.3m of 26 guage wire that I got from Maplins (found 28 guage too thin).

I use a 5A adjustable power suply (a replacement laptop powersupply) on 20v (its selectable from 12 to 22v in 1v steps and this seems to provide me with enough control over the heat in the wire.

I use a really cheap and chearful setup for the swing arm cutter - it uses monofillament fishing linean eye hooks (the type for you use for hanging pictures on walls). The monofillament line is virtually frictionless going through the eyehooks (i.e. no need for wheels). When you want to change the cutting ratio (tapper of the wing) you just unscrew the eye hook and screw back into new position.

One issue - my wire looks thicker (.45 mmOD) than MattyB's stainless steel, so you might have to allow for a slightly wider cut.

For the bow I use about 2m of 25mm OD white water waste pipe which I bend into a curve and tension when I attach the nichrome.

Usual warnings about protective gear (especially eye protection) apply.

I suspect the nice looking stuff that MattyB has cuts more consistently.
