Hand Launching

Would walking or jogging while initiating a throw help a little?

Thanks

G'day mate,
If I'm by myself, then I'll hand launch myself. With this model it is important to have a breeze of some sort to launch into.
The EDFs need airflow to provide thrust and lift. Also, The airflow from launching into the breeze provides flow over the control surfaces, ailerons and elevator, to allow you to have control.

Having someone else launch is better because you have both hands on the controls, BUT, make sure you have someone who has done it before, BECAUSE, I had someone throw one of my models straight into the ground who was not familiar with it.....P#**ed me right off.

Don't bother running, just give it a good shove, slightly upwards, but get it straight and level ASAP so you can build up some speed, and therefore, control.

Hope this helps.
Regards
Rob

Mate, I use the 2200 mAh batteries, I just shove them all the way forward, and adjust trims airborne. The model does float quite a bit on landing.
Are you keeping the wheels, or are you going to fly it as a belly lander?

If Belly, then you will need some protection for the Vertical Stabs.

Hey Rob,

How are you holding the battery in place? Velcro?

Also, are you pushing the battery all the way forward to where it touches the nose gear?

What brand battery are you having good luck with and what is the c rating? I've got 2200mah 3S 25C AND also 30c.
I cant wait to give her a go.

Should I pull the fans and static balance?

thanks and cheers!

The Battery is a tight fit, so, it stays in place (I will go down and check. I have 20 models so I can't remember exactly how the BTY stays in place)

Turnigy 2200mah, 20-30C.

Static balance, I didn't and have not struck any dramas as a result.
Have you replaced the ESC's? If not, history shows that they won't last long.
I got just 3 flights from mine before one failed so I replaced them both. Fortunately for me, the failure occured on the ground.

I'lll get back to you (boomerang theory) re the security of the battery.
Rob

Battery Security

I have a strip of Velcro on one side of the Battery and a corresponding strip on the floor of the fuse under the cockpit. (see pics)
The cockpit, once in place, secures it from above.

My HK A-10 arrived last week and between other duties I've been poking at it 5 minutes here and 5 minutes there to stick the pieces together. I know zilch about EDF except what I read here and the A-10 is only my second modern foamy after a life time of wood and fiberglass models, but the A-10 looked like a fun plane to plunge into EDF with.

Anyway, I've wondered about two things: What about spraying some sort of clear coat on the paint to make it a little less susceptable to scuff and scratch damage? Here in the desert we fly off of rocks and sand and the finish is going to take a beating even using the landing gear. Second, the vertical stabs seem a bit wobbly. Are you guys using glue with the screws or just the screws?

I am impressed at how nicely the various foam bits can fit together. The last foam plane I built was a Midwest Models "Attacker" in 1979 and the styrofoam was a bit less precise (and less durable) than modern foam.

G'day Doug,
Yes, clear coat it, I've also put glassing tape on the leading edges and all contact areas to protect mine a bit.
Yes, I have glued and screwed the fins. You'll still get some fishtailing in flight, but it will be OK.
Some advice, if you loop it, start at height and make them BIG loops. there is a lot of flex in the wings, if you loop too hard or turn too hard you'll snap a wing. Basically, fly scale. Use at lease a 2200 3 cell. ALSO, you may want to look at replacing the esc's, not a good track record with stock items.
The model flies well and floats in nicely for landings.
Rob
