I lauch mine with a underhand gentle toss. I make sure to toss it completely level and it seems to work fine. Try that?

We had a perfect 70 degree day with very little wind here in Connecticut, so I decided to maiden the little jet today. As you can tell from the pictures I didn't get very far. I used the 250 mah lipo that tower recommended for the jet and placed it all the way forward like I read on this forum. I launched the jet into a very light 2-3mph wind while holding the throttle at about 80%.....and the jet basically went nose straight up to the sky (about 10 feet) and then came right down nose first. It seemed like the weight of the lipo just tore right through the nose of the jet. I repaired it and went back out a couple of hours later and the same exact thing happened except this time I had more damage (pictures are after the second crash). Any suggestions on what may be causing this (I made sure that all servos were moving in the proper direction)? Also do you think my shotty repair work is going to make the jet unflyable?? (I have a micro t-28 and brushless p-51...never crashed either of them). I am off tomorrow and will make another attempt this time with a camera recording so that if the same thing happens it may be easier to point out what I'm doing wrong.

I would ck the cg. I have a penny in front of my 250 battery. May be a bit nose heavy. Nose heavy you will fly again, tail heavy you only fly once. I do use the runway to take off. I find hand launching you tend to get a bent nose.I usely get a bent nose form a dead battery having to much fun.

Sorry to hear about your crash, it sounds a lot like my experience, mine did the exact same thing on my first few outings. My fuselage looks much like yours. Solid velcro on the battery ensures that it doesn't slam forward in a crash. This will spare your fuselage. I have also added foam in the slot in front of the battery compartment to strengthen things up a bit up there in case the velcro lets go. Sure it adds a few milligrams of nose weight, but this thing needs it.

Good luck!

Also sorry to hear about your crash. Your repair doesn't look too bad and should be flyable. One trick though, if you dipped it in some hot water prior to repair you could have gotten out a lot of the creases, etc as the foam will expand back to its original shape. It's a great tool... hot water! I used it on mine already and it worked very well.

I had a similar set back on my maiden. However I added a dime underneath the battery and it flew flawlessly. The dime weighs 2.3gm for reference. I've flown it 4 times since without a problem but I found that the dime is just a BIT too heavy.
I've now gone to 6 BB's (as in BB gun) placed just in front of the battery. The 6 BB's weigh approx 2gm. I haven't had a chance to fly it yet with the change but I'm hoping this will get if flying very neutral. I'm also using Hyperion 240's which are approx 1.2gm less in weight than the stock 250mAh battery.

With the added weight in the nose (dime or BB's) my CG is NOT at 70mm. I would say it is more like 65-67mm from the leading edge. I have the 70mm marked on the bottom of the wings and it balances in front of this mark but I can't get the exact measurement. I'm using 2 pencils stuck in foam to balance.

I also found that moving the dime around even just a couple mm's makes a big difference. Of course on small airframes like this any change can be dramatic.

I glued the fuselage after getting the elevator linkage installed. Wish I'd taped it like was my original plan. Only one side of elevator wanted to work correctly. I'd glued in some pushrod guides and ripped the fuselage to shreds attempting to remove them. A total loss. Gonna use all the internals in another try at an He-162.

I still have a new wing/tail set so maybe I'll get another fuselage kit later and build another.

my hobbyking nanotech 300 2S arrived today, they weighed in at 16.85 grams and I reduced the length of the power leads, so that saved a bit. They fit well; I hope to try them tomorrow

Mine is flying great with a TP 2S 250 ma pack. Here are some pictures of mine. Stock fan/motor Hacker X-5 ESC 4 servos, 2 elevator, 1 aileron & 1 rudder. XPS Nano receiver

Buyer Beware! IMHO It ain't worth 40 bucks let alone 140.
Wasn't it WC Fields said there's a sucker born every minute?
Our LHS sent them back, wouldn't even carry them due to the disappointment when the box was opened....

Apex' - no offence but your post is not very constructive.

Have you flown one or do you own one? I couldn't see any posts by you of late referring to either.

If not - it doesn't even sound like you got to see inside the box as your LHS 'sent them back' and all you have to go on is his word?

He must of sent back every other UM model he has ever ordered in as they pretty much look the same when 'flipping the lid open and looking inside'....

Our LHS can't keep them in stock. Opinions vary. Guess I would ask "what is the reason for your statement?" The GP Tiger Moth was so bad in the durability department I had a similar opinion. However I own both and wouldn't change history in my experiance at all.

Has anyone tried installing a Spektrum Rx in the plane? It looks like it would be fairly easy. I just don't want to spend another 20 to purchase the anylink adapter so it works with my DX8. It would be cheaper to just get a 2.4 Spektrum compatible Rx and not have to deal with the anylink at all.

Same here.. My LHS is out again

has anyone gotten any real world MPH numbers on this little guy?
thanks

What the hell kind of post is this?

Sure makes me look like a fool with two of them doesn't it?? Funny that I think it's a wonderful plane as long as you use the correct CG location and not the one in the GP Sabre manual.

I only have my make believe world numbers..
