Title: Vintage inverted heli flight Post by: anwar on May 30, 2009, 03:58:09 PM Must be a great achievement, all the way back in 1982 !
The gyro technology during those times was fairly primitive, compared to what is available now ! http://www.youtube.com/watch?v=JX1gTG_2l_Y Title: Re: Vintage inverted heli flight Post by: lynxheli on September 14, 2011, 06:25:07 PM He must have been an ace then even WITH gyros its difficult to control a helicopter

Title: Re: Vintage inverted heli flight Post by: lynxheli on September 14, 2011, 06:42:46 PM Right :banghead: beats me too Title: Re: Vintage inverted heli flight Post by: spitfire on September 14, 2011, 06:48:21 PM I dont think it is an electric. Correct me if I am wrong but you can find a muffler just behind the landing gear. and little bit of smoke coming from it.
You can see the smoke clearly at 0.50 , 1.10 and 1.18 Title: Re: Vintage inverted heli flight Post by: anwar on September 14, 2011, 06:51:34 PM http://www.1017.org/cricket/competitor.html
Certainly glow from what I can gather... smoke being not prominently visible can be attributed to factors like video clarity, engine tuning, fuel blend etc. Title: Re: Vintage inverted heli flight Post by: sunk? on September 14, 2011, 09:58:23 PM hi guys.
definatly liquide fuel ....as said above around a min in video can see the smoke......... no flying with battery in the 80's all too heavey packs needed prob had a 'new electronic gyro' then not the mechanical one the head and tail were prob ally as standard then too. my 600 hirobo is from the 50's and head and tail are quite heavy ally, not like the modern light weight ally. regards don |
