Andy Meade Posted October 18, 2017 Share Posted October 18, 2017 Good to see you here Joel Guvnor - the bleed system is in place, I'm sure Joel will post a video at some point, but I've seen the video on facebook, looks great!

Tim Cheal Posted November 22, 2017 Share Posted November 22, 2017 I have to compliment you Tony on the article in December RCM and E. It really highlights the level of success, and disappointment, you experienced during the development. And for someone like me who has built 2 models from plans, its actually encouraging that, even for the experts, not every flight is a success! Your comment about descending when the aircraft is yawed in the hover is spooky, because it replicates exactly what the real aircraft did (I think I mentioned I flew Harriers in the RAF, actually I flew GR3s, AV8Bs and the GR5/7) because the yaw thrust duct (puffer duct) contributed nothing to total lift (pitching up or down, and small amounts of roll, produced only a downward thrust from the appropriate puffer duct, so it contributed to the overall lift). Well done, and it you do decide to get involved in a RTF version, count me in!! Finally, I am intrigued to know who the AVM mentioned in the Autumn Special editorial was, as I probably flew with him in the 80s and 90s. Fantastic work, and well done again.

Tony Nijhuis Posted November 23, 2017 Author Share Posted November 23, 2017 Thanks Tim for the kind comment......its amazing how models do replicate the full size....even the Harrier. I once designed an 8th scale miles Monitor and it was not a nice flying model but never knew why until I read some original test reports on the full-size....the title was entitled 'tried tested and failed' Since the Harrier article was published I have carried out some more tweaks on the loop tuning and have improved the control and stability further so its now a nicely sorted model.... now working on a turbine version (but not a Pegasus) ....using hot gas on all four outlets....

Tony Nijhuis Posted November 24, 2017 Author Share Posted November 24, 2017 only needs 48amp to hover on a 3S 3200 Quote Link to comment Share on other sites More sharing options...
Tom Thomas Posted November 25, 2017 Share Posted November 25, 2017 So what's its flight time at those specs? Quote Link to comment Share on other sites More sharing options...
Tony Nijhuis Posted November 29, 2017 Author Share Posted November 29, 2017 3.5mins hover or 5min combind Quote Link to comment Share on other sites More sharing options...

Lorenz Mueller Posted January 27, 2018 Share Posted January 27, 2018 You should enter the Harrier into the VTOL world championship - see www.dorniermuseum.de/rc-vtol-wm Lorenz Quote Link to comment Share on other sites More sharing options...
Tony Nijhuis Posted March 14, 2018 Author Share Posted March 14, 2018 Just a quick update on the Harrier....two more prototypes being built in depron, this time all laser cut .... managed to save yet more weight which is good news....not ruling out a very limited run of kits as I have secured a batch of control boards, programmable servos and new 64mm fans... Also been experimenting with some new 64mm fans with larger motors that AEO over in China have sent me....these can comfortably operate on 4S so reliability and additional power should be very welcome and hopefully more duration Still no progress on the ARTF version unfortunately...a number of manufactures/supplies I spoke with i think got there fingers burnt with the latest VTOL Transition and the Horizon Convergence so the appetite has been lost for now...

Aaron Hill Posted May 11, 2018 Share Posted May 11, 2018 Amazing job Tony. Best implementation of scale looks with reasonable flight time that I have ever seen. Nicely done! Quote Link to comment Share on other sites More sharing options...
Aaron Hill Posted June 4, 2018 Share Posted June 4, 2018 Hi Tony. Any updates with your new 4 cell motors? What FC did you use? Quote Link to comment Share on other sites More sharing options...
Tony Nijhuis Posted June 5, 2018 Author Share Posted June 5, 2018 Hi Aaron, No up-dates as yet as I have taken some time out of aeromodelling...burning the midnight oil over all these years has taken it toll on the health over the past few months....close to burn out!....however, getting back in the swing of it with renewed vigour so expect to see some up-dates over the next few months.... The FC i have are a clone of the NanoWii board bought from the US..... A slight set back was I crashed prototype No.11 below....on a positive note it was pilot error and i did learn that the CofG is absolutely critical to achieve a smooth transition....If the CofG is forward by 1/2" or so, the model rears up in transition. if the CofG is rear by 1/2" the model pitches down on transition....

Aaron Hill Posted June 7, 2018 Share Posted June 7, 2018 Thanks for the update. Sorry to hear of the crash but I'm sure you will be back in the air in no time. Tried to get a copy of the RCM&E issue you published this bird in but but paypall just keeps spinning. Will keep trying. Quote Link to comment Share on other sites More sharing options...
Aaron Hill Posted June 11, 2018 Share Posted June 11, 2018 Finally got to see your article! Now I need your plans for the airframe Quote Link to comment Share on other sites More sharing options...
Aaron Hill Posted July 12, 2018 Share Posted July 12, 2018 Hi Tony. You mentioned you needed 48amp to hover. This is the amp draw of just one edf and not all four together? Quote Link to comment Share on other sites More sharing options...
Tony Nijhuis Posted July 12, 2018 Author Share Posted July 12, 2018 48amps in total so 12amps per EDF,,,,can just squeeze 3.5mins of hover from a 3200mah lipo Quote Link to comment Share on other sites More sharing options...
Aaron Hill Posted July 19, 2018 Share Posted July 19, 2018 Wow that sounds incredible. I can't find a single 64mm fan unit that draws less than 30 amps by its self. I'm willing to purchase a parts list from you if you decide to make one available. Until then I look forward to seeing more.
