That is what killed mine! So how do you overcome that? I never have a problem hand launching other planes...just the FJ

No offense taken, Ben - you're right, it's a pretty terrible launch. My friend was insistent that I let him try. His first attempt was equally bad and he wanted a chance to redeem himself. I also throw right handed but have no problem keeping it straight. Just takes some practice I guess.

Are you keeping your arm straight and smoothly thrusting the plane forward like a javelin, concentrating on avoiding any twist? Here's another good video demonstration. Not sure I agree with launching with the motor off though.

That video is a perfect illustration of how to launch almost any small plane. Good post fishboy! I think launching motor 'off' is ok as long as you have a low AUW, but I have never had problems launching my regular weight Funjets #1 and #2 with full power on. Still got all 3 fingers and thumb on my right hand to prove it!

Just wanted to share something one shouldn't do.

I flew my funjet yesterday with a 6S setup (2x 3S in series). I canopy popped off and so my 500mah rx battery and one of the 3S batteries fell out. The second 3S battery was held down with velcro, so that was good. I couldn't find the two batteries that fell out But other than that, the plane's still good to go. I just gotta find a better way to keep the latch on as well as velcro ALL batteries down in the canopy.

Big fat rubber band.
Several STRONG magnets.
Those MX latches are a JOKE! Don't EVER rely on those things.

Three batteries in a funjet?

Why not use a BEC?

I've forced myself to learn the left-handed launch, keeping my right hand on the stick. Saved my FJ countless times Im sure.

Where do you get those rare earth magnets that everybody raves about?

I am another Righty that taught myself to launch left handed. In the beginning having my hand on the stick saved it many times. I always launch 3/4-WOT and haven't recieved so much as a scratch. I also tend to launch at a bit of an excessive angle but my FJ has more than enough thrust to compinsate and is well above its stall speed when it leaves my hand. I let go straight from my launch about 10'-15' then straight up.

The video launch was lousy, up and a distinct tilt to the left.
Most of it is just throwing it hard, flat, and not freaking while you reach for the sticks.

RE-Magnets:
My ACE hardware had the magnets, 10 for like $4.

You can order them at GoBrushless.com for a prompt delivery or
from http://www.dealextreme.com/details.dx/sku.10305 (China).
Do a search on magnets, they have a bunch.

Cheapest place I found is --

http://www.rare-earth-magnets.com/Se...goryID-28.html

The ones I use most are Product ID: NSN0601

They're 50 for $8.99....and V-E-R-Y strong....they have a Pull Force of - 2.14lb/971g. There are other larger/more powerful magnets...but I found them too large for most of my RC Plane applications (ie. To large in diameter to use for a cockpit, etc.). Maybe if I get into the Large Scale planes...but for planes with 20-50" wingspans...these do me just fine.

If you're REALLY cheap...and have a dead motor laying around....strip out the magnets. Brushless motors all use (I think) Rare Earth magnets. At least, the cheap one's I've torn apart all did.

Hope this helps...

-Eric

Michael's Craft stores are another good source locally. Very strong and you get 6-8 of them depending on size for arouns $2-$4.
