Could it be the bearing sleve? They do wear out. I'm starting to see mine show similar signs, and that's my guess. I'll just upgrade to ball bearings this time.

Time Out. I'm butting in here....


I'm now the proud owner of a gws tiger moth 3D. It's in the mail and rather than try to read kazillion threads (i've read some before buying), I've got a couple quick Questions. Great huh?

I've got an extra 400xt (approx 1000kv) and some 1250 2s batts. Is this a suitable power system? prop range?

Can someone reccommend a good build thread or site? Maybe with some basic needed mods? I know from experience with my Beaver that the GWS instructions may be a little lacking lol.

Thanks,
Ralph

LOL! Yeah, there have been a fair share of strange flights too. I was so excited about getting my Aero Ace up at least 400ft, I forgot that I needed to get it back. My wife said, "Isn't that kind of high up there? Can you get it back down?" "Uhhhhh.... no. At least not around here". So we watched it climb as it blew over the horizon. That was it's maiden!

Buzz, DOH!!! Don't do that to your Lama now! LOL

So updates on Moth 2.0 (or is it 1.5 since I am using the original main wing). Thrust angles & CG were right on the moth, the problem was in the CDRom motor being over propped (just like you all told me).

Tonight was beautiful (1-2mph winds), and I was out with the Moth for dusk patrol. I am quite happy and it is also a lot quieter. I was flying at almost walking speeds, really great! It works a lot better now with that 8x4HD prop and prop saver. The wife was rather amazed with the flight and after about 10 mins it was time to run some errands.

Thanks again everyone for the help!

Prop Wash?

OK, I'll demonstrate my ignorance again (I'm very good at it!), and ask what I know has been asked before. What is the difference between the HD props for the Tiger Moth, and the other aforementioned props? My knowledge is of the orange colored ones. I have always run the 9x7 orange prop, on a stock IPS/"A" gearbox arrangement, never had any problems. However, I will be going to a Feigao on TM #2 and probably should be considering a different prop/gearbox arrangement. As the Forengi would say, "I'm all ears!"

Doug,
The HD props are an enyirely different shape than the slo-flyer prop. They were ment for direct drive. They are a lot stronger at the base of the blades. ie. They don't break as easily. The HD props are available in most sizes. BTW I believe all of the GWS props are available in 3 colors now, Orange(of course), black and grey,when you can find them. I always ask for any color but orange.

Yup what Travler said, also the HD props draw less amps than the Slow Fly ones.

I was using the Feigao motor suggested for the IPS replacement on A gearing with a 9050HD prop on 3s740 Etec pack. It had tons of power, and I will use it again, for now it is going to sit in the old fuse I need to locate a few items to fix that fuse up. I just like how quiet this setup is.

Ok, just this once! I didn't know the difference either!

Should be a lot of fun around here the next couple of days. That hurricane/tropical storm is forecast to pass right over us. I'll have to make a raincoat for the moth!

When I used the Feigao I just removed the IPS motor and slid the Feigao in it's place.
Used the same exact gearbox, heatsink, prop (9x7 SF) and batteries (2 cell 830).

Worked great, more power and longer flights.

Doug, I remember you said you liked the gear noise and there is nothing wrong with that.

The only reason I switched to CDROM direct drive is I personally prefer the almost silent flight of the direct drive.

Yes, there is a lot to be said for that. I also like the quietness of a direct drive. However, slipping a Feiago into an existing GWS IPS gearbox is appealing, might try it on TM #1, and I do believe that "buzz" (gee, can't get away from this guy! ) is part of the unique Mothness feature of the Pico Tiger Moth. Yep, I am hooked on the sound.

Will I be going the right direction with an orange prop, 9x7, using the Feiago motor? Or, should I be looking at the HD version? Lastly, are the HD props listed separately from the orange ones on GWS product sites, such as Balsa Products? If I can lower the amp draw on the Feiago power train with an HD prop, it would be in my best interests to do so. I have just had such good luck with the stock IPS, "A" gearing, 9x7, orange prop combination that I am somewhat spoiled. It has been sufficient for 970+ feet altitudes (...sorry Buzz, ) so I may need some direction here.

Hi Doug, I believe using a HD prop will give a lower amp draw than the closest size SF prop. Even with the stock gear ratio there is plenty of power, so lower amps will translate to longer flights.

As far as props from BP Hobbies, there's good news and bad news.
The good news: They have both 9x7 SF and 9x7.5 HD props for $1.38 each, so it shouldn't hurt to pick up both and compare them for yourself.
Now the bad news: they're all out of orange and only have black in both types.

The feigo ####25L has oodles of power on an 8X6 SF prop in an "A" box

on a 2 cells 830mah, it will achieve sustained inverted and do outside loops

at 3.7 amps static...

it was the only plane i got to fly last Sunday between raindrops but it was a blast...so much so I've even considered breaking down and installing flying wires just so i don't pew the scrooch.

but maybe not

Chuck

P.S. i know i said it before, but I am really impressed with this set up...I'll have to get Wayne to get Video next weekend (barring storms)
