Hi

I've seen tons of manufacturer offering "improved" and more "resistant" 2mm carbon frames for a lower price than align's standart ones but what if one really wants 1.6mm carbon frames at a lower price than aligns?

I'm seeing an opportunity here for guys that care more about weight than added resistance?

I wish I had a bigger cnc machine and I would cut them myself using some higher graded carbon than aligns... it would be lighter, same thickness and have 3 or 4 goodies in it

Any ideas?

Tony

Tony,

I agree. I have the 1.6 frames and they seem to be fine except for some flex. I would think a substantial weight dif?

Hum... I think I need to start snooping around for how much a 1.6mm sheet of carbon or carbon-kevlar fibre sheet goes these days. I have a friend that has a 4 x 6 m cnc router (12 x 18 feet +/-) but he doesn't know squat about CAM/CAD so I would have to design the entire thing myself... alot of work but maybe if there are more guys interested it would be doable

Tony

PS - I wonder if a carbon/kevlar mixture at 1.5mm wouldn't be even better... need to study the specs.

What are the 3 or 4 goodies?

One idea is to increase the size of the 3 cyclic servo holes and the tail servo hole to accept the new, larger JR servos.

Just my 2 cents...

Well I wish I had one as big too... it cost him like 50K and every time I see it working my jaw drops lol

mine is only like 140mm x 140mm and 0.05mm precision. His is 30 times bigger and has a precision of 0.02mm per 1000mm. Only problem is that its working almost 24h per day (he's in the marketing business) but I could probably rob him a few night hours if I showed up with the design and a hand full of carbide end mills (he's pretty anal about breaking his own bits on "unknown" materials)

Need to study more

The goodies could be an extra slot for a mixture servo (instead of separate plate = less weight), a custom nano slot for throttle (instead of another plate = even less weight, for those who would want it) and maybe two cuts (one in front and another in the back) to insert a carbon plate to act as a gyro support. It would save us the hassle of removing the tape from the gyro each time one needs to remove the tail output box to change gears for example

Just ideas

Tony

Yep, I like that last idea. Spent too much time removing the old crap from both the bottom of the gyro and the tail box after having to remove my Solid-G gyro and send it in for warranty work!

Hey guys I'm not sure if this helps but Heli-Direct has 2.0mm CF and G10 side frames as well as rotorworkz side frames for the 600N.

Yes but they are all 2.0mm frames. I have an infinity set right here Lovely frames really but I was looking at stock 1.6mm for potencial weight reduction.

Mikaelni: Very nice... where did you get them? Or did you draw them yourself?

DWG files

Hey Tony, send me an email with the goodies you want to incorporate to the frames, and I can make the dwg files, so your friend can cut them!

Folks,

I replaced 2 mm carbon frames with 2 mm G10 and weight difference was 36 grams. I don't think weight diffecence between 1.6 mm carbon and 2 mm carbon is significant.

Just my 2 cents

whats the weight difference between align 1.6mm frames and the 2.0 mm align ones?

I just bought the 2.0mm ones but the 1.6mm ones are on my heli. Anyone got the weights?

I posted the 2mm frame weights a while back (aftermarket though) I think it was like 20gr heavier than 1.6mm (per side). If I remember correctly, each of my frames was like 91gr while the 1.6mm was around 74gr or so... I have to search for the post.

ForrestGump: those 35gr you mention, are total or per side? what ended being heavier? G10 or Carbon? What was the final weight?

Tony

Tony,

36 grams was the difference between carbon 2 mm frames and G10 2 mm frames being G10 heavier, but this was the difference for BOTH frames together.

Both frames were aftermarket frames bought at readyheli.com
