Check it out new frames that take standard servos no bell cranks needed and the servos have a bearing supported bridge.The canopy mounts are also break away mounts so you don tear the whole side frame up in a crash instead you have one little part to replace
I had a chance to put about 4 hard flights on the new frames and they are very imppressive
The pics show a 10s stick pack and a 6s pack you can also mount the 6s vertical up front.

SWEET.... Charlie showeds me early pics of these and I thought is was a AWESOME frame.... 10S guys should love this for sure!
BUT... how about some vids man?

Bob,
A video Soon very soon :mrgreen: I have a lot of work on the plate between orders and real job stuff but we hope to get something going soon

This is the first aftermarket frame that really caught my eye. Can you post some good close-ups, especially of the servo mounts?
Thanks!

Does the stock align canopy fit without modfication?

I have the current model HFE conversion and the stock 600 canopy fits like stock. From the looks this one will mount the same. I'm sure the canopy is off in the pics to show off the frame. :wink:

Yup those look good indeed. Wish they were available now as I just toasted my stockers at the SHAG 2007 funfly,,,, oooops! :oops:

Hey battlercon,
Havn't ALIGN called and offer you a job yet :lol:

I really like the battery inline with the boom! How is it banging around?

I will get better pics when the kit if closer to release :wink:
No modification to your canopy is needed you have about 20mm clearance past the stock 600L.
Bobby and a few others are and will be helping in testing this kit for me so when we are closer to a production part I will share better pics it won't be to long before release if my real job wouldn't keep me so busy :bomb:
Waelo, That is funny I like the idea though :D because sometimes my real job as a Radiation accelerator engineer (Cancer treatment machines)stinks :badair: pay is good but not as much fun as making heli parts
As for the battery mount its not bad I wish stock plate was just a tad stronger. but I have other ideas to give that warm and fuzzy :wink: it is just not shown on this frame.

Hmm. Looks like the servo positions have changed. Now the rear servo has its arm pointing forward. This geometry is less favorable than the previous setup with regards to CCPM interactions. Probably can be solved with a couple of mixes if need be, but something to think about nonetheless.

Kenkamm the prototype frame setsup really Square and flies really square
W e are currently flying it on 6s 1p 5000 evo packs wiht the Neu motors and theCC85

That's what I'm talking about! I wanna be high on the list to get that frame. Looks like the best one yet!

Kenkamm the prototype frame setsup really Square and flies really squareYeah ok, I know you think I'm crazy, but it's true. You'll find if you look at swash plate tilt (use a swash level... OMG) throughout the pitch range it will be tilting forward and back depending on what your pitch is. Allow me to illustrate why in the following pic. This WILL cause CCPM interactions, which, depending on what mood people are in, can be "the end of the world" or "no big deal." It can be mixed out if you know how, but it IS there and is easily noticed in flight.

So why would that be any different than the Bell cranks used by Align? They also tilt the links away from the swash at high and low pitch?

Align's bell crank pivot points are very close to the main shaft, so no, they don't have the same problem as this. You see here, the rear servo arm pivot point is way back... so you end up with different angles on the rods as they go through their range of travel.
Look at the stock setup and move the cyclic forward. Front bellcranks rotate down, just like the front of the swash plate. Rear bellcrank rotate up, like the rear of the swash plate. This is the best way to keep the rods very nearly vertical, all the time. The fulcrum of the swash and the fulcrum of the bellcranks are nearly on the same vertical axis. There is a reason they stuck that rear bellcrank between the frames, on the same rod as the other two, in a hard to reach place... because it's closer to ideal geometry.

One concern I have with this new frame design is the reduction of available swashplate vertical travel due to the increased distance between the top and middle main shaft bearings (to accommodate the servos). Some guys wanting to run extreme amounts of collective pitch may be disadvantaged. I'm guessing there's about 7mm less vertical travel available.
Also, Align were very clever to position their bellcrank rod right in between the rear and front (pair) of swashplate balls when viewed from the side. This is what gives it that near "perfect" geometry without any noticeable interactions.
kenkamm, you're right about the ccpm interactions on this new frame, but as you say, it can be worked out with a mix. I've been considering going without the bellcranks on a stock frame. Even in that config there is a slight interaction because the pushrods are not at the same angle from vertical between ele and ail/pit, but it's less severe than the interaction on this new frame since all the arms can be configured to come from the "outside" if you flip the rear servo over. But again - a mix in the right place will resolve it. It's just a matter of being able to tolerate those "crooked" links. :D

Charlie I want 2 sets what is the ETA Approx. ? :smokin:

Lovetofly, there are changes not seen in the pics that will accommodate pitch :wink:
As for interactions you are correct but... they will be very minimal as servo throws have changed. Lets just say this set up has SUPER FAST servo response :mrgreen:
yes it is responsive!!! All ccpm machines have interaction and yes you can take the time to fine tune it out wiht a mix or Swash menu that is all ihave flown is ccpm machines ........My comment was based upon throwing a swash tool on and squareing the swash center top and bottom and flying it i havent even bothered to fine tune it and it flies really square

I have no doubt you will work it out, but I'm an engineer, so I just love the technical discussion!
So, what's your trick to allow enough pitch? I've studied the movement of the stock head and this would be a problem unless you modify the head linkages a bit.
