this is just for a little research...
please post your opinion along with a type of flyer your are (sports/3D or AP) and the reason of your preference.

Thanks!

CF doesn't bend in a crash. It's either good as new, or broken--there is no intermediate state.

Aluminum bends. If you crash an aluminum frame, it might still work but your linkages will probably not be straight anymore which will affect the flight characteristics.

CF is lighter, but it is also more expensive. I prefer CF for the frames and tail boom, but for any structural part (such as blade grips or bellcranks), I prefer aluminum.

I like CF for the weight reduction but hate the price. I'm too cheap to pay that much for something I way crash. After I get my crashes down to once a year I'll prolly go CF all the way around.

G10 is great stuff but still not enough people/manufactors using it to build heli parts. I think it's the perfect gap filler between the aluminum and carbon fiber. I'd go G10 on everything right now if it was availible.

Aluminum bends when you crash...ask me how I know. Most crashes it needs to be replaced and very hard to straighten if not impossible.
I run it simply because of cost. When i get my crashes down to one a year then up to paragraph one I go!

Really!

MA uses it, we use it, heck even Irwin uses it!! Synergy, I think even Hirobo offers a frame set in G10. Outrage also offers it, including the Bright orange for their 550!!

now Thats the type of reply i was looking for...

now, Aluminum is out of list...i think the only people fly aluminum would be sports flyer with experience...or who dont have many crashes.

Thanks Chris for your input...really appreciate it.

Chris,

if you dont mind me asking, what type of G10 sheet do you use in the Gasser....any source i can get the sheets from?....

If u remember, i do have one of your bird and till now, i did'nt know that its G10...really excellent frame.

I always respect that

I usually use FR4 sheets for PCB designing...they are a bit yellowish white type color but really strong...

i think i know which g10's are those now

Just to make point, I guess I was refering to Century and Thunder Tiger, the two I personally fly day in and day out. There still is not very many using it and those that do still only offer limited parts or only on some models. For such a great product at the price point it's at you think someone would capitilize on this. Some of the aftermarket guys have on a few of the heli's but not nearly enough.

Guess I should get a CNC router and go to work......

It looks like that G10/FR4 is an excellent choice...

any source where i can buy 0.93" G10/FR4 sheets in black?

If I can get hold of FR4 in the UK what thickness would you recommend for a gasser?

Thank's aliazhar

I have seen some cheat carbon before where someone has used G10 and laminated a thin layer of carbon on each side, what’s the point of that apart from charging carbon price or looks maybe.

Someone even used a sticker that looked like Carbon on a piece of PLYWOOD!!

That's funny....

it will be good to buy it from a good source like McMaster.com...atleast we are sure that we will never get cheated there.

Plywood???? !!!! never heard that before

There is more to a heli's frame then the material it is made from.

If we are talking sideplates of the same size and thickness. The most rigid material is the proper grade of aluminum. But it has no tolerance for any misalignments. If one does not take the time to insure all components in the frame are properly aligned (which requires extra percision in the manufacture of all other components also) the vibes from the engine/clutch system will cause premature cracking due to metal fatique. But, if built with the proper attention to detail. They will generally have less flex through hard maneuvers upstairs resulting in less wear of gears, bearings, clutches and other compoents.

Most any composite can be made to be very rigid, but if they are not specially made pieces, that have strategically inserted re-inforcing ridges and formers molded into them (as seen in high end race cars)they will be relatively flexible.

So if we are talking sheets, as used in the sideframes of our helicopters, then they will need extra CNC machined components bolted to them in strategic locations to insure the same flight rigidity in the air. This in some cases can result in the frames actually being heavier then that of a properly designed aluminum framed heli.

If we compare sheets of Carbon Fiber to the same sized ones made of G-10. You will find that the C/F sheets are much lighter and much more rigid then those of G-10, but also substantially more expensive. G-10 can even be cheaper then a proper grade of alluminum. And as a sheet of G-10 is also easier to cut to shape then aluminum or C/F it makes it a sweet choice for a manufacturer.

Is it the better choice??? that is very debatable. IMHO, for flight considerations...NO. For cost of crash repair - MAYBE.

I think many manufacturers are now going to it simply because of the cost advantages.

Personally I think stainless steel has them all beat but it does depend on type of use. For stick banging it would be carbon fiber, least weight. For moderate flying I would say G10 or aluminum with aluminum being the lightest. For camera work I would go with G10, weight giving stability. You could do the same with aluminum by doubling up the side frames.

Most people choose what they like to work with and then swear by it, right or wrong.
