Thanks

I have a Dynamix on my Webra 61 RE Redhead - its a superb carb. Sadly, this one isn't pumped. I wish it was,

Quite a while since I updated this - mainly because I was building my little Fokker Eindecker. The construction work was mainly done, so it was a case of glassing the Fus, and applying 2pack paint and then covering and final fitting out.

No photos on the glassing/painting but the engine was fitted

A brand new Webra speed 91. The manifold came from Weston UK. They made a beautiful job of it too.

The canopy is held in place by 3 screws into hardwood blocks. I may add a 4th at the front

Tuned pipe exhausting through the rear of the canopy.

Fitting out the radio gear was fun. I have never had so much space to play with...

Air retracts gas bottle gives some idea of just how much space there is on there

CF Elevator pushrod for the elevator and closed loop rudder control. The only problem I have is that the inlet NRV leaked so I have a replacement on order

All I really had to do now was add a bit of decoration. You may want to close your eyes or squint a bit..

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..
