Tony Nijhuis Posted February 25, 2019 Author Share Posted February 25, 2019 Thank you Josip and Greeting!.....hopefully it will be a success and based on my previous up-scaling antics, they do perform better the large they get.... I dont remember there ever being a Skyway's Concorde but I remember a Robbie foam version and of course the COX peewee pusher plan from the 1970's Quote Link to comment Share on other sites More sharing options...
Piers Bowlan Posted February 25, 2019 Share Posted February 25, 2019 Yes, I have the old Concorde 'Cox Pee Wee pusher plan', must be one of the first I bought - but never built! Would be nice with two 50mm FMS fans, simpler than four fans (I am not a purist!). Perhaps best built of depron, to keep the weight down.

Simon Chaddock Posted May 11, 2019 Share Posted May 11, 2019 That is tremendous! With all that thrust (and weight?) I suspect it will fly fairly fast. Strictly of course the visor should come down as well. Quote Link to comment Share on other sites More sharing options...
Dad_flyer Posted May 12, 2019 Share Posted May 12, 2019 Amazing, awesome, lovely, fantastic. The 11am Concorde roar was part of my schooldays. Occasionally spotted her coming back on a balmy summer evening, a high and silent dart. Is this one the 50mm EDF, or the big one? Quote Link to comment Share on other sites More sharing options...

Piers Bowlan Posted May 12, 2019 Share Posted May 12, 2019 Really awesome Tony, well done. Can we look forward to a plan in the RCM&E Special later in the year, by any chance? Quote Link to comment Share on other sites More sharing options...
Tony Nijhuis Posted May 12, 2019 Author Share Posted May 12, 2019 Thanks Guys, there will be a plan at some point but no deadline for me any more!.....just enjoying the model and getting it sorted and really fine tuned Quote Link to comment Share on other sites More sharing options...

I bet you are well pleased with that one. Steve Quote Link to comment Share on other sites More sharing options...

Stephen Jones Posted May 19, 2019 Share Posted May 19, 2019 Tony, Just how much weight have you added in the finish, It seem to struggle this time around to get airbourne and that landing was not as good as the last. And it seems to slide in the air as if it`s on ice. Just how windy was it this time around from the last flight. Steve Quote Link to comment Share on other sites More sharing options...
ken anderson. Posted May 20, 2019 Share Posted May 20, 2019 Well done Tony,looks nice,it did well to get off the bumpy old ground there I thought,the landing looked ok,as long as it wasn't to much stick bending for the elevator/flare....

Simon Chaddock Posted May 20, 2019 Share Posted May 20, 2019 Very nice Tony and particularly that landing on grass that for full size would have been a corn field! A bit cheeky but my only criticism is for that for true scale the wing from the front should look like this. My favourite Concorde picture. All done before the days of computer simulation it does rather show where all those £millions went on wind tunnel testing. . Quote Link to comment Share on other sites More sharing options...
Tony Nijhuis Posted May 20, 2019 Author Share Posted May 20, 2019 The grass was quite long so those 11/4" wheel were struggling....a lot to ask really for a 5lb models The finish covering has added another 5oz so AUW is now 5lb. The power to weigh is now approaching its limit with these fan units...The fan units I used are the 50mm HK 11 balded 4S EDF units. These are not great (and are not available any more). The FMS 50mm 4S unit which are lighter (will save 6oz over the 4 units) and delivers another 6oz of thrust per fan (or another 1.5lbs over the four units), should really liven the model up.... the MK2 Concorde will have these plus a 5S pack!!!!! I prefer to use just one battery pack to serve all four EDFs as it makes the weight less and save on multiple charging.....Unfortunately the current draw from a 4S pack 14.4v does cause the voltage to drop over the 4 motors so each motor is only getting 3.5S under load......In the past i have gone up another cell count so multiple 4S motors will generally be happy with a single common 5S pack. As there will be a high voltage, the current draw to match the power, can be reduced sightly so a 4500mah 5S lipo will give similar duration as a 5000mah 4S lipo (as long as you don't fly flat out) Simon, regarding the wing tip drop, there is a conundrum here... the wings will flatten out in flight and at mach 2, they are almost straight.....so for scale flying speed...I think i got it about right Quote Link to comment Share on other sites More sharing options...
Tony Nijhuis Posted May 26, 2019 Author Share Posted May 26, 2019 Decided to stripout the old Dr MT units and replace with the FMS 50mm 4S units....The extra thrust from each fan should be around 120g or 4oz.....That 480g or 18oz additional thrust over the 4 units. The weight of the FMS units are less so the overall weight saving was 5oz so the AUW dropped to 4lb, 11oz Tried the model at Hastings yesterday and what a transformation!!!!....no problem taking off from quite long grass and the climb out was a good 40deg......Now cruises at around half throttle!...still using the 4s 5000mah pack too....Happy days Quote Link to comment Share on other sites More sharing options...
