Hey Salamander Friends!

This thing is back in supply again...in Hong Kong.
I've already ordered one from each of these sites: HobbyKing and RC-Castle. (That means I've ordered two, one for me and one for a friend.) I'm basically curious if both models come with the same components, particularly the ESC. There's a big price difference between the two sites, but once postage is calculated, this difference is only about $15.

Personally, I don't think the effect will be so bad to prevent flying the model, although it might yaw more in the turns. You may consider simply raising [what's left of] the vertical stabs and making them higher so, in effect, you don't have to cut off too much from below the horizontal stab.

In my opinion the vertical stabs are relatively high above the ground considering the horizontal stabs V-form. And if the verticals stabs are getting scraped off, then you may be landing the model too slow and possibly trying to plop it down from a high angle of attack. The 3 landings I made with mine—before it suffered some kind of uncontrolled roll and then downward spiral into the ground from about 30-meter height—were rather flat, albeit fast, and the tail boom (and stabs) never touched the ground.

Hi Rob, this is not an easy bird to fly. This is my 3rd EDF and I've flown the Kyosho F-16 and Art-Tech Mig-15. Both are lighter and flew straight off my hands (I can only do hand-launches where I fly).

Even with upgraded 4800kv outrunner motor with 6 blades in the same 64 EDF housing and 25C 2000 mah Lipo, it will dip (nose down) after a 15-20 degrees up handlaunch... if I manage to elevate in time, it will climb out at 40 degrees with power... otherwise... heheh, its dirt time... the upside is the EDF is mounted on top so no damage and no foreign objects sucked into the EDF. hahah.

Not discouraging you, this bird looks real good and unique in the air, just want to let you know what you'll experience and be prepared for that maiden.

Cheers!

Hi kamhw
thanks for your advise, i will be nervous about the maiden but excited at the same time, are you saying with the stock 4300kv motor and 5 blade fan it wont hand launch, or maybe very difficult?

thanks again
Rob

No, that is not what I meant. I got this as a kit only (plane plus EDF housing only) so I did not get the chance to try out the factory 4300kv motor.

PS: Adjust your aileron throws and put in some negative Expo (35% for mine)... this bird rolls like a low-wing warbird.

Han,

You might consider a bungee launch. If you look back through these posts I have a video of my model's last flight, which was its 2nd bungee launch.

Prior to that video of a successful bungee launch (and of its 4th flight attempt), I had flown it twice with the landing gear attached. My home club in the U.S. has a hard surface runway so I had thought the landing gear would be practical.

Well, it wasn't. To avoid the risk of stalling on landing I landed it fast (power on about 1/4-throttle) and this worked fine. But it also used up more runway than was available, about 300 feet—and that bugger was too squirrelly on the ground.

So the following flights I used a bungee; the 3rd flight landed on the green grass parallel the runway that extended much longer. Easy. Smooth. And even though I still landed it fast, the model stopped much sooner. I'm sure this would work on a dirt surface as well.

Thanks James, I found the post (#145) but do not see any video attachments or links. Are you able to provide the link so I can see how you bungee launch the salamander? Thanks

Did you guys ever see the Video of the Review I did on the model? I think a Bungee is overkill IMO.

I disagree. It's simply an issue of a failsafe launch. Additionally, Tom Hunt threw your model on its first flight. And he is no EDF novice. He also didn't have a transmitter in his other hand. Therefore why not, as pilot, didn't you throw it?

Of course after you re-powered the model with a beefier setup a PIC hand-launch became a no-brainer. But I suspect a majority of EDF fliers don't do that with this model—and mine was plenty fast enough on the stock setup.

Another no-crash-option may be to simply let it do a belly-slide takeoff from smooth grass.

both threads leads one to ask - has anyone flown this without crashing it?

someone mentioned that the gear tracks well, so isn't rog the safest way to get tthis edf off the ground?

He threw the model with one hand, while holding the TX in his other. I'm not so sure I understand what you typed/are asking.

If this was a HEAVY underpowered EDF model, sure I would have tossed it for him. We did not figure on having a problem hand launching it, and we didn't.

That included both stock and non.

I do have to disagree with you RE Bungee being a failsafe launch. We have a fair number of models <Prop and EDF> that go up with a Bungee. That said one more then one occassion I have seen a muffed launch.

Bottom line is do what YOU want. We hand launched and had no trouble.
