Thanks, I'll check it out.

Made a flight demo video from this morning's flight. If u have lived thru the 80's before, TURN UP the volume of ur PC!!!

Enjoy :

Great flying...
is it in Yishun ???

Hi Guys, just sharing my first heli fuse scratchbuilt fuse...made from foamboard...

[Adrianli]

Very nice. What size is it???

[slammer617]

Hi Adrianli....its a compass atom500 frame...

[perfect1]

nice

Ver nice. Hi slammer, how do you do it?

[slammer617]

@ perfect1...here is the pic of how the build started...







the base frame were first drawn in autocad to get the dimensions. I had to overlay the airwolf fuse drawing to get the right size of the fuse for it to fit in the atom500 frame.

Great job.

Really nice.. That must be very light fuselage u got there

Are u going to harden the structure?

Hi SH...the fuse is done but not yet painted and i plan to maiden it first before the paintjob, that will give me some clue whether to apply some sort of hardener or just leave it as bare foam...i assume it will show some cracks or gaps after the flight but i doubt it as foam is quite flexible having some experience with scratchbuilt foamy planes...as long as the gears are rigid and stays in place, i dont foresee any problems at all, i had it bench tested and the fuse handles the vibration well not showing any sign of fatigue...the frame shown is not yet complete, i added some more cross braces to make it a bit stonger to hold the outer panels and i can see i holds well...

Slammer dude, you are a genius! Foam...incredible! I am just a lil worried about the fuselage coming apart during flight but I am sure you would have got that aspect all figured out. Do post a vid or some pics during the maiden.

[slammer617]

thanks a bunch feudallordcult...no worries about it coming apart, im more concerned about the tail not yawing on one side knowing how wide the vert stab is, but ill be checking on that on the maiden and might do a little mod afterwards...cheers

The most important area that require rigid (IMHO), is the location that hold the main shaft to the fuselage.

Again, IMHO, if your main shaft can move around (or stir around) inside the fuselage, when u spin the rotor blade up, and together with "wheels" based heli, the heli might goes into a "ground resonance"... meaning the heli will shake itself violently and if the resonance become severe, the heli/fuselage might break apart.

So, when u spin up your heli for the first time, do take care to see whether will it goes into ground resonance or not.

Bro Super-Hornet, this is really good input, i will check on that, i have already asked a friend of mine about this...yeah, i did notice that at the rpm before take off when the wheels start to wobble...i have not yet really hovered it as the temp outside is biting cold, im afraid my fingers would freeze and I would loose control and the loose the heli as a result....really appreciate this comment as i have not really came to hear about this until this post...i have been flying this heli for more than 2 years now but its got skids rather than wheels so i have not experienced ground resonance before even once as i always get my blades tracked perfectly....two thumbs up to you bro.
