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...

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.
