Tiny problems (part 1)

[Buddly6]

Hello all,

long story short (very) my tiny doesn't fly. It has a lack of power. It weighs in at 5.0 oz and uses a dc1717 on 8 cells. It also uses a GWS 8 by 4.3 prop. I am in desparate need of help.

i had the exact same problem with my tiny. the motor sky hooks and rigging gave me (dc 1717) was of very poor quality. if i were to get the dc 1524, i would need a new wes. prop as well as lithium batteries because when flying a high power motor on 8 50 mah cells, you will be able to tell that half the juice is gone as soon as you fly it to the other side of the gym. i had just ordered a lite stick as well so took the motor off the lite stick and the lithium batteries as well and it will climb veritcally.

Actually Mitch, I figured it out. I was WAY under-proped. Now she flies like a champ!!!

My Tiny was a slug @ 4 ounces with either a 1717 or A 1524. Used several different gear ratios and props including the expensive CF ones. I tried 9 cells and even 10 but then it would only fly for about 2 min. Not long enough to be any fun. Mine has the conventional tail.

So like the other fellow I strapped on a GWS motor/gearbox combo and use 6 or 7 270mah NiMH cells. In a word, IT ROCKS!!

Use a GWS 10 prop to hover or an 8 for duration. Heck even with the 10 prop I still can fly for over 5 min.. And it will do everything my bigger 3_D planes will but in my backyard.

I use an MPI receiver with the cases removed, the servo wires are soldered directly to the PC board. The servos are HS-50s with the cases cut away and all the wires inside reduced to the size wire that comes on the HST connectors. The ESC is a
JMP HF9 60 MHZ MOS-FET CONTROLLER which is connected to both the battery pack and the receiver with JST connectors.

You would be surprised just how much weight you can eliminate by removing cases and switching to JST connectors with the smaller diameter wire. But you had better be good at soldering and have steady hands.

BTW: Because of the added motor power and all the other weight savings I made I decided to install a servo for each aileron.

Now I have flaperons, airbrakes and mix the flaperons with the elevator. I also use a rudder servo.

I have not weighed it in this configuration but would venture to guess it must weigh all of 5 1/2 ounces.

SLOWFLYER, you problibally had the 12V version of the 1717. Just a theory......
