How long does it take to install your belt drive kit?
And how hard is it to do?

It take 30-60 min, not hard to do. Just light modifications to the frames for wich we provide jig.

Corrado,
Thanks for your replies!
Does the belt drive kit weigh more or less than the stock shaft setup? I would think more, and if so, how much more?
In regards to balance, does the belt drive kit add weight to the nose or tail? It might seem like a dumb question to those of you who flown for a while, but I AM a newbie. . .

I guess the belt finally arrived at http://www.rchover.com since there are pics on the main page


I honestly don't know about weight before and after, all i can tell you is that my Zoom, with plastic frame, was at 504 grams with belt kit installed.
Here is my setup:

Heliup Belt driven tail
Axi 2208/20 (mine is a rebadged twister 300/20)
11T pinion
Hitec HS-56 all around including tail
Irate 850 5S
Schulze 835 receiver (very similar to berg)
SBEC 6V
Esc CC P10


regards

Corrado

yummy....
Got the belt drive in and tweaked...read a different forum where boyd (i believe) did an awesome job with the pics and blow by blow assembly. Too much labor to fill out all the stuff to put a post up there, so hofully, someone'll see this.. he he.
I did run into the problem with the binding, settled for a washer between the bearing plate, mounted to the outside of the frame, and the see-saw assembly itself....seems to have worked. Funny though....nobody's mentioning what we have to do to our poor motors and pinion gears for that stuff to fit!...I had to grind mine almost half off to get the top of the pinoin gear to be even with the top of the big white gear. Funny...it seems the more I radious the top of the main gear, the lower the belt rides...that's the other thing I read about and was wondering....belt tension...I have that black crud on my bearings too....will that go away or what?..I did the tensioning by simply spooling up, and tightening till there was no more slipping.trial aqnd error, over and over a few times, till it was quite all through the "spoolong up" process....hope that's about right.
Now I just can't wait for that beautifull new C/F frame to come!!...nice work Corrado!
And great job Boyd on the cool write up!

Thanks for the kind words Bob. Revisit the thread on the other forum as we have uncovered a couple issues with the Heliup.com kit that you need to know about. Pinion setup and the rest of the review is waiting for the fixes from Heliup.com before proceeding.

Sorry 'bout that, no pricing yet since release is still a few weeks off as I am told.

Corrado....
I noticed in the pic at the top of this page, that you are useing flanged idler/ tensioner bearings...this would resolve the problem of the belt riding on top of the main gear...As I mentioned before, I rounded off the top of the main gear w/ a dremel while the motor was spinning it, came nice-out, but just lets the belt ride that much lower...any more, and it's gonna be hitting my pinion.
That's a neat motor too..Just put a himaxx in mine, but my buddy, who has designated me "mechanic" for his heli, is gonna need a new motor soon. I did two belt drives in a 10 or so hour stint! Feel like I know a few in's and out's with it now..Love it!
The black crud I mentioned earlier is seeming to be tapering off..I guess the belt is "breaking in"..
Thanks. Bob.

I was just testing them, the belt with those was running too high. I have been running my belt kit for 150+ flights slightly touching the main gear to have it as low as possible and no problems at all.

Corrado..
OK...seems like it's not really taking any material off the belt...but it's still kinda strange...those nice bearings made it ride to high....hmmmm..damn. Maybe a future modification to the tail boom spacer plate to bring it down just a tad would work?...beautifull kit though...nice parts...(my ONLY complaint is that I only got 3 out of the 4 small screws for the see saw in the kit...but of course, like all prepared hobby folks, had some in the "collection" )

The problem is that the way the spacer is built there is not enough room to bring it down much without separating it while machining the part. The belt really doesn't suffer from touching the gear, mind that i had a lot of flights on HV setup putting a lot of stress on it but i am still on my first belt.

I talk too much...
Me again....I looked at the pics again (of yours) and saw that the belt is actually riding about exactly where mine rides now..

No no, it is the pic that makes it look lower than it actually is. Believe me with those bearings the belt runs a good 1,5 mm higher than on standard bearings.

You mean like this?? Don't look at the finish quality they are just prototypes.
