Title: scratch built electric park flyer(help needed)
Post by: Bilal on October 06, 2012, 10:45:25 AM
Good morning everyone,
am building an electric park flyer, aileron trainer with the following specs as if for now,
wingspan: 914mm
chord: 196mm
material: balsa
but before i start i want the experienced guys to have a look on the airfoil profile that i have selected and tell me whether it would be ok for an aileron airplane with no dihedral or not.

besides if you have suggestions for a particular plane that has good flying characteristics, then please step in and guide me, because am a beginner just trying to step into this wonderful hobby

so all your valuable comments and suggestions are welcomed
regards
Bilal

Bilal, the aerofoil is good for parkflyer use... But i think u can keep the lower part of the aerofoil flat instead of making it curved, even that will work

Bilal..... Stepping into hobby.... AND I thought you have already flown 2-3 of your planes....you are into it dude.....

What i do when i want to build .....keep looking into HK site for pics and select a model then decide on my own dimensions and mods.... you have approximation of prop motor esc etc from the model.

ex. I plan to make a 34"+ WS trainer from thermacol so this is what i found...

Aerofoil is also shown... have a look

@Rastsaurabh: (chuckles)......sir, am stuck into an endless cycle of build-crash-build process.......but this time i want to build something that would survive atleast a couple of flight session,.......afterall, i have to learn flying too  :giggle:
 
and that was a really good idea you gave me their :thumbsup:, thanx.....people like you make my life easy ;D ;D
but how you draw/design the fuselage by just looking at the pics.....i mean where you get all the proportions from?

and now since you have started the topic, so i want to build this fuse,...can you tell me how to draw it on paper? :headscratch:

Same with me... i have made 2 planes and lost one in crash.... other one ( AXN floater lookalike) could take beating and is under repair. have also made a delta 24" but somehow felt that it is too small so making a 34" delta ( HK wing wing lookalike).
Coming to fuse... i know your inclination towards BALSA.... so it will be a little tough still it depends what size of wood is available.
You know the length---you know the places it has to be extra strong ( from Nose till trailing edge of wing).... i haven't tried anything with balsa so cant give more tips.... but one design what i have in mind and will try once i get time..... thermacol fuse sided with coro!!!! see this design....

Bilal,
I am also new in this hobby , made model from depron and crashed. Than I made a SAPD and experienced,  that SPAD can handle some crashes, tough landing  and easy to rebuild. My spad gone through 3-4 crashes with out any issue and I am learning flying from that.You can try it..

Bilal which material are u using for ur build, as it it depends on the material . which can handle crash.

I have roughly build a plane. which is made of coro. and believe me bilal it will handle all ur crashes.
bcoz i am sure , no one can fly as bad as i can  :giggle:.
i will post some pic , once i reach home.

@Swizera: Sir untill now all my planes were made up of thermocole.....but lately i've realised the beauty and ease of balsa construction....and am loving it  ;D
so for this build I'll go for a full balsa fuse and a thermocole wing in the beginning :giggle:......once am confident enough, i'll build a treditioal balsa wing........THAT'S THE PLAN 8-) ;D

Bilal if you want to build, try Blue or Cub plans, there are lots out there. Basically any high winger would suffice your requirements
