Thanks for the reply. I've been throwing it frisbie style (left hand) at full throttle and it rolls left to almost fully inverted. I thought full power might be the problem. I'll try 1/2 power next time. I can't throw it overhand do to a back problem. I didn' have this problem with the C.

You can set the low voltage alarm to any number. My packs are around 9.8 volts when I land. The 9.6v setting is because the packs sag a little bit at the end with full throttle. That way I have a reserve at lower throttle to land without listening to the alarm.

I only put on enough throttle to feel that the plane wants to get away from me which means that there is enough thrust to fly the plane, that's all that is required; I have never actually looked it's a 'feel' thing for me but probably 25-35% any torque roll is barely there so that the launch is calm and easily controllable.
I think the problem that most have is to try to launch with WOT which in turn leads to the torque reaction and things happening too quick to react to whilst your hand is off the stick.

I throw with my left hand so I can keep my right hand on the stick (mode 2). Next time I'll launch it at a reduced power. Thanks.

The vert stabs/rudders have to be CA/epoxied into the fuse, unless you use the supplied double sided tape
How durable are those thin foam rudd hinges i wonder. My Radian Pro has the same deal on the Rudd,but they covered it with strips of clear tape. I re-did it with clear packing tape.
Yikes!! double sided tape for the Vert Stabs? yea ill be gluing them for sure.

Nice vid btw!! i cant wait to get mine now!!

They do recommend to CA them also. regular CA can be used with this foam.

I CA'd strips of 150 grit sandpaper to the finger grips. The difference in grip is amazing. Although I am still setting up, I'm not sure how you guys can launch without the extra grip of the sandpaper. The grip really felt super slippery to me as it came out of the box.

I was out having fun with the Q today when an elevator landing got a little ugly. I eased off of the elevator a little too soon causing it to land with the nose a little downward , the magnetic nose worked like a charm but the fuse didn't fair so well. Right where they put the fiberglass reinforcements the foam split cracking it all the way across the belly to the leading edge of the wing . Upon inspection i found it had little to no glue , this isn't the first time this has happened to me, my carbon z elevator counter balance broke right at the reinforcement too. it had little glue either ! I don't know if it is necessary but i would wick a little thin foam safe Ca around the reinforcements just for extra insurance ...It glued back together easily and you can hardly tell ( but i know its there) ....wish i could glue the prop back together , No lhs close to me has the stock 6x6 , i did try an apc 6x4 and it was horrible ...Has anybody experimented with anything else ?

I got props today!! flyin tomorrow

I busted the stock on the third landing...

If I understand this correctly: If i discus launch with my right hand and the right wingtip low; would the torque swing me into level flight??

Started out as an APC 7X5, reamed it, cut an auminum spacer, and tried it unmodified, pulled 58A, so decided to cut it down for use with the stock ESC. Turned it down to 5.875", radiused the leading edge tips, balanced it, and now it pulls 48A and 575W, should pull a hair over 40A on a new battery in the air. Well within the stock EC's rating of 40Z constant, 55A @ 15 seconds. The chord is wider, especially at the tips, and being the pitch is mostly calculated based on an average across the prop with the inboard being a higher pitch than the tips, the pitch is likely steeper than the original 5" rating being a little more than an inch worth of the shallowest pitch was removed, might be closer to 6. measured 44oz of thrust(stock prop at 37oz static), so vertical should be a lot better, I don't know how speed will be affected, stock was low to mid 90s with a fresh pack. This plane, like most with very high KV motors loses a lot of speed and power with even a small drop in voltage, on a fresh pack it is just shy of an honest 100mph level, after 3 minutes with more than 1/2 the pack's capacity remaining, it struggles to top 80MPH, and no longer has unlimited vertical. Hopefully this prop will not reduce top speed by much, it measures about the same pitch as the stocker, just with a wider chord, if that is the case, it may be the perfect prop, much better vertical, without losing any speed, and still be OK with the stock ESC. Hopefully I get to try it out in a couple hours after work, I have high hopes.

Thanks for the heads up killowatt. I'll have a look when i un-box mine. As for Diff Props i think just alucard0822 has ,with his Modded Prop.
So a 6x4 Sucks? That sucks!! I have quite a few of them on hand. I should of got LHS too order me 2-3 as spares..just in case.
I'll look around HK i guess or RCtimer.
