Cant say enough about how easy using a throttle cut switch on the hand launches. Just roll up the gas to 65-90%,throw and hit the switch at the same time,Not even throwin that hard,haven't even had a close call. Just hoping the hand grip survives for awhile...
The shallowness of it,does seem to make you feel like you have to grip it tighter than the old stryker. = more grip wear. ?
I throw it about 45 degrees up, and hit full throttle as soon as I can see the whole airplane - with my arm out of the way.

With regards to the torque roll problem, how much throttle shall I use for a backhand Frisbee launch, 50%, 60%??
Sam, I personally use the discus method to launch wings, I am left handed,fly mode one and use a neck strap. So what I do is hold the plane in my right hand then put in enough throttle so that I can feel it wanting to pull away from me then holding in a little up elevator just give the model a gentle toss and away she will go, no fuss, no drama,no torque roll (you only get this problem with full throttle launches) just like on the video you posted.I hope that helps.cheers

I have a bad back and I'm unable to do an over hand throw. I think that is part of the reason that the launch is such a big topic here. Everybody will be comfortable with different launches.

I do throw mine with my left hand frisby style with full power. I've been flying the C for the last 6 years. When I launch the C with my left hand with full power it will go into a 45 degree left bank before it starts flying good. With the Q I'll launch it the same way but it will go nearly inverted to the left before I'm able to upright it and fly. I'm not sure why it is different. I may need to launch it with less power. I've been in the dirt twice launching it and with the C I've never been in the dirt. Any feedback would be appreciated! I just flew my 9th battery in it this evening. When I get it figured out I'll video it.

Sorry if i missed it, there is been alot of good stuff on here now that alot of people have gotten planes.
Just for comparison, I had my timer set to 6 min with the C and with th Q I have it set for 4 1/2 min. I'm conservitive with my batteries. I like to land above 11.1 volts. Of course that is with several full throttle passes.

I used CA for the rudders... I dont trust tape on critical control surfaces...I lost a vert stab on my C during a flight and it wasnt the most fun flying her that way since the one didnt come off completely but rather got stuck turned out about 45*!

Got another flight in tonight...with video, just before the thunderstorm hit!

Can you set the alarm to 11.1 volts? I've been looking into the DX8 but I don't like to run my packs down that low.

I put a strip of rubber shelf liner over that pastic piece and the battery stays put. It can't slide at all.

I am getting around 7 minutes of mixed flying...with mostly 3/4 throttle and a few WOT passes across 300 feet of field.

Has anyone else measured their speed with something?

I can't wait till the speed mods start. Will that be a seperate thread?
I used an onboard GPS and mine was 105 mph with no wind and from level flight (no dive). The fastest my C went was 74. My C does have a lot of lights on it though. I want to clock it with a radar gun with the GPS onboard to compare the numbers. Maybe this weekend.

Got a chance right before dark to test out the prop I modified, and it lived up to my hopes. MUCH better vertical, took about 3/4 throttle to maintain a climb, full throttle accelerated up briskly. Got only 3 good speed passes 1 minute into the battery, 85-90mph, about the same as the stock prop, perhaps a hair slower, but definitely worth the tradeoff in thrust. Everything came down acceptably cool, the battery after 6 minutes was at 3.75v per cell with fairly mild flying, so a bit more power hungry, but not by much, all in all it seems like a decent upgrade. That was till the last elevator/parachute landing, right before heading home, and the damn thing broke, must have ended up straight up and down, one blade stuck in the dirt and snapped. Luckily I made templates, so I'll be able to recreate it, but it is far more rigid than stock, so I guess this is to be expected. have some pics and video of the flight, a few hand launches, a few elevator landings, short vertical pulls, a couple speed passes, and throttle stabs from slow speeds to see what it did. I didn't fly fast for long, and didn't fly anything that impressive, it was about 15 minutes till dusk, so the plane was getting a bit hard to see.

I did multiple cross wind passes and got a consistent 96 MPH readings in level flight.

My FJ with Grayson Super Mega did multiple 102 MPH passes cross wind in level flight.

I did one pass in the Q with the wind and went 117 MPH!!
Great report...How many cells and prop?

CA on the rudders? Or you mean you CA'd the Rudder fins in the Fuse. Sorry im confused lol.
How are the rudders hinged anyways?

Which way does the plane torque and how much throttle do you recommend?

Live(thin foam) hinges on the rudders, CA fabric hinges(8 or so 1/4" wide strips) on the elevons.

The vert stabs/rudders have to be CA/epoxied into the fuse, unless you use the supplied double sided tape

it will roll and yaw to the left, right rudder corrects for it. I normally go about 1/2 throttle after launch, it doesn't need a whole lot as long as you throw it well, and get on it quick. The throttle off launches in my vid on the previous page probably aren't even 1/2 throttle, and dead sticked for a couple seconds after throttling up, flies off and climbs out very nicely once you get the magic blend of throw and throttle
