I really like my 120SR. It has grown on me and I think it's a great heli, but there's no way I would take it over my Quark. My Quark is my prized FP heli

It turns out I lost a flybar weight in my last crash.Went to two HS and they didnt have anything I could use. So in a moment of genius I decided to use BB's They seem to be working pretty good. I have a new flybar on the way.

Thanks Augusto for the change in order.

Tech problem: tail unit

This morning one of my Quarks just sort of fell out of the sky. This one is subject to seeming to lose signal occasionally, in one particular position in my back yard, and I forgot about that and couldn't get it back before it hit the ground.

After replacing the main blades, I noticed that it was glitchy in flying circuits. The tail would seem to hold in one position, then "suddenly" jump to where it was supposed to be. I've found that when this happens, if I carefully check the tail unit, I'll find a place where the gears aren't meshing smoothly. Sure enough, I found two glitchy spots on the driven gear.

So the question is -- has anybody found a way of dealing with this other than installing a new tail unit? I've tried now and again, but haven't succeeded. New tail units are a bit pricy for such a small problem, though....

I'm afraid you are screwed. Sometimes the problem is due to the shaft being bent a little (it bends rather easily). But it's just about impossible to straighten without wrecking the gear.

I have seen some quarks with a Hughes 300 cabin on them... is there a vendor for that? or is it just from another machine like the Dynam or similar?

No, that's not the problem this time. Just two little glitches in the driven gear.

Blades?

Haven't been flying heli's for a few months till this weekend. Course the Quark got most of the indoor flights as usual. Six 7 to 8 minute flights and 2 broken sets of blades. Just wondering if there are any new developments in blade options? I see some talk about carbon fiber in-lay's? whats that all about and is it saving a lot of blade breakage? How is it done, or is there someone producing a better blade these days??

I think you're referring to the Helimax Rotofly canopy.

http://www3.towerhobbies.com/cgi-bin...?&I=LXJPU5&P=7

They're pretty flimsy and won't offer much in the way of protection. On the other hand they're lighter than the stock canopy. Also, they're not a direct fit so you'll have to improvise to mount it - I used an alternate mounting post through the hole in the frame just aft of the control unit.

Balr glued some CF strips to the underside of the blades. It helps keep the blade straight (less coning) and also helps with the breaks/bends on tip-overs.

The latest is using Quark SG blades. Of course they cost a bit more, but there are several on here that have tried them within the past couple of weeks and are reporting good results (more lift, better performance). They should be more durable too.

Have you checked your flybar phasing?

Do you mean the topic on P25 - orientation of main shaft components? I did check that, but both of my Quarks are setup 180 of what's shown in that picture (the blade grip head and flybar are rotated 180). I might change this first - I think Dmala did some experiments with this as well ... Don't know why they're different - the came this way.

I was just about ready to pull the entire head & main gear from Good-Quark and put it in Evil-Quark to see what effects that had. I'm going to flip the head and flybar around first ....

Thanks for mentioning! Odd that the manual shows the head assembled both ways depending on whether you're looking at page 25 or pages 33 & 36. A riddle from Hirobo?

(if this isn't what you're referring to please set me straight - )

Yes they are very flimsy. I like the style, so I relocated the grommet of the canopy to a newly made hole near the back edge of the canopy, which matches the position of the canopy support rod.

At this rate I'll need to order some more from Augusto soon!
What is Augusto's web site. I seemed to have misplaced it..
Thanks
