Remember to look up


“Remember to look up at the stars and not down at your feet. Try to make sense of what you see and wonder about what makes the universe exist. Be curious. And however difficult life may seem, there is always something you can do and succeed at. It matters that you don’t just give up.”
Stephen Hawking

Thread: Rearwin Speedster 6000
14/03/2018 16:22:26

So the 2018 Indoor Nationals didn't happen - sadly called off due to the 'Beast from the East'. It did actually save my personal embarrassment as my little Fokker EIII didn't perform quite as well as expected. I did learn something from the experience and that was don't leave it so late for next year. I also learnt that it may be better to choose an easier prototype.

Flying indoors was not as stressful as I thought it would be, there is more space than expected and the setting is actually quite relaxed. Great fun. However, for next year, I want a model ready for the start of the indoor season so have been looking for a candidate.

I have always liked the charm of period 1930's aircraft and I have been looking at this aircraft as a build candidate for a couple of years now. Its NC15865, the 2nd prototype Rearwin Speedster 6000 (not the later M variant) which is still operational in the USA. Fortunately, there are several decent photos of it on the internet - hopefully enough to build my scale dossier.

 

Working from a 6000M 3-view, there are some differences - mainly a different fin and cabin window layout and a slightly different cowl to accommodate a different powerplant. Fortunately, I have been able to extrapolate the correct dimensions and shape from the photos that are available. It should be accurate enough.

I am building this at 1/10 scale giving a wingspan of 975mm or thereabouts. Target mass will be 150g - but I'll be happy if its less than 175g.

Its going to be a slow build, I need to finish some models before I start another one like this but hopefully it will be completed by October.

The plan looks like this at the moment - mainly a tracing from the 3v but with some structure being added. It will have 2 x 3mm square balsa/carbon composite spars to help keep the wing strong, straight and stiff, the rest will be mainly traditional stick and tissue construction.

Getting those wheel spats and undercarriage fairing built light will be a challenge

This image shows the earlier fin and cockpit variance - transposed to my plan.

 

More to come.

Just heard that probably one of the greatest scientists ever - Stephen Hawking - has passed away.

Very sad news.

Took me a while to read and mainly understand ' A brief history of time' but it was worth the effort. Gave me a tiny glimpse into the working of a great mind.

Correct me if I am wrong but isn't there a problem using 2.4 close to heart pacemakers. Or is that all radios? This being the reason that you have to go outside a hospital to use a mobile phone. or at least into the corridors.

I cant comment on the risk to pacemaker users, but the use of phones in hospitals and aircraft is I believe FUD. I think the real reason is that Airlines and Hospitals simply don't want people having loud conversations on mobile phones in a stressful area.. Remember a phone is transmitting/polling very regularly. Its still an RF/digital signal. Doesn't really make any difference whether someone is actually talking..

Thread: HS 2
22/02/2018 09:21:45

I live near the Powerhouse of the North - just outside Crewe which is a rail hub and will be a new HS2 hub. I can already get to London by train in about 90 minutes which I think is quite acceptable. I fail to see any benefit of HS2 except to increase the distance of a viable commute to London nearer Manchester. I don't know anyone who is in support of this. The cost of a rail ticket is already expensive and I would imagine will increase substantially with HS2 which will price out the average non business traveller from using the service.

Are you going to statically balance the wings before covering Dan? You may find that the weight disparity may not require 20g in the tip.

Model looks amazing - it's a real credit to you

Thread: The WORST plane you ever had?
20/02/2018 15:50:40

I had a MFA (I think) trainer is about 1976. Horrible - Heavy plastic Fus and heavy foam wing and under-powered with a McCoy 19. Best I ever got was a long (full) powered glide resulting in crashing into a wall.

If you remember it please don't remind me. I don't want to know
