Tom Wright 2 Posted May 20, 2011 Share Posted May 20, 2011 Tony the model needs a name how about ........San Francisco ? Quote Link to comment Share on other sites More sharing options...
Tony Bennett Posted May 20, 2011 Author Share Posted May 20, 2011 pile of scrap springs to mind. "frisco" sounds good.lol well i did leave my heart there. Quote Link to comment Share on other sites More sharing options...
Tom Wright 2 Posted May 20, 2011 Share Posted May 20, 2011 Any more talk of SCRAP and i will send the the flying squad round to charge you with misrepresentation LOL. The penalties are quite severe unless you repent the model could be confiscated and given to me. . Any way Frisco sounds good could hardly call it "little cable car" i suppose you would come back with "scrap little cable car" . Mind you "half way to the stars" sounds ok .Edited By tom wright 2 on 20/05/2011 21:18:58 Quote Link to comment Share on other sites More sharing options...

Tom Wright 2 Posted June 3, 2011 Share Posted June 3, 2011 Did you get the ROG or was it a hand launch ? Quote Link to comment Share on other sites More sharing options...
Tony Bennett Posted June 3, 2011 Author Share Posted June 3, 2011 rog.gave it a push start and she lifted off just.not enough oooompf to overcome the headwind, so it stalled and dived into the ground. got to fit a bigger motor and repair the center section of the wing. still it flew sort of.

Tony Bennett Posted June 4, 2011 Author Share Posted June 4, 2011 i got a 2 cell lipo 7.2volt job. i'm trying to do everything on a very tight budget as i have no money at all.. got a bigger motor out of the odds and ends box and will see what happens. might go back to airfix kits at this rate.

Tony Bennett Posted June 6, 2011 Author Share Posted June 6, 2011 well bigger motor fitted and a new prop. hmmmmmmmmmmmm worse than last time, so smaller prop fitted and we now have lots of speed across the field, but still no lift. so i packed up the main wing leading edge and had another go.still no joy, well the wheels just left the ground then one caught in a rabbit scrape and it spun round and stopped. just dont seem to be getting any lift from the wing.maybe some fixed flaps might help. or a bonfire.

Eck Posted June 6, 2011 Share Posted June 6, 2011 Don't be tempted, Tony - the fun soon goes out of whirling them round the room making "bbbrrrrrrmmmmm" noises! (just don't ask how I know..........) Quote Link to comment Share on other sites More sharing options...
Wiltshire Flyer Posted June 7, 2011 Share Posted June 7, 2011 Tony, try removing the wheels all together and fit a folding prop, may just give it the grease it needs? Only other thing i would try if it were mine, would be to extend the wing a little at the trailing edge, don't give up mate, it looks great Quote Link to comment Share on other sites More sharing options...
Tony Bennett Posted June 7, 2011 Author Share Posted June 7, 2011 yeah i thought about fitting some fixed flaps on the trailing edge to increase the lift a bit. the whole point of the build was to have a cheap plane i could practice take off and landings with. my £10 a month budget just dose not allow me to buy rtf kits that i know will fly.so i will keep plodding on with this one while i start another scratch build out of the scraps i have left over. anyways onwards and upwards (i hope ) Quote Link to comment Share on other sites More sharing options...
Tony Bennett Posted June 7, 2011 Author Share Posted June 7, 2011 yet another failed evening. i must have done something fundamentally wrong some where as it just will not fly. so its time to retire it to the wall and build something else. something simple from a plan and see if i can get that to fly.Edited By tony bennett on 07/06/2011 21:15:56 Quote Link to comment Share on other sites More sharing options...
Tom Wright 2 Posted June 8, 2011 Share Posted June 8, 2011 Tony . I can only say that a test glide ,from a hand launch should tell you every thing ,you have checked C/G and rigging ,it can only be underpowered,the only other thing is brushed motors and 35 MHZ can be problematic . Just to check back what is the wing area and AUW ? Quote Link to comment Share on other sites More sharing options...
kevin wild Posted June 8, 2011 Share Posted June 8, 2011 hi not sure if it's a posibility or not. just an idea is it posible that you've built negative incidence into the outer wing pannels that's countering the lift from the centre section ? I don't know anything about polyhedral wings it's just a thought kev Quote Link to comment Share on other sites More sharing options...
Tom Wright 2 Posted June 8, 2011 Share Posted June 8, 2011 Tony Its not a failed evening ....,just another step in the process of getting to know and setting up an experimental model .. Quote Link to comment Share on other sites More sharing options...
