I have a problem


The plane is lazertoy Tumble Bee http://www.lazertoyz.com/Tumble-Bee-Kit_p_155.html
17" wingspan 16" fuselage

The Mini Mite-15 motor http://www.rchobbyintl.com/index.php...mart&Itemid=69
btw I like the motor!


I am trying to find the right prop for it on 3s lipo
The is my auw is 8.9 oz(252 gr)
2s lipo with 09x47 GWS prop throws just over 10oz thrust at 9.5 amp WOT
That great but since I could not get it balance at the right CG (plane is still TAIL heavy)! Every thing is as forward (ESC, Battery, receiver and LG) I decided rather just add nose weight I put on some lights all front of the CG.the lightening built to use 3s lipo bright and at 2s lipo they work but not to bright. AND yes I probably could of used DIY lightening to work better on 2s lipo but I wanted a just bit more thrust for that AUW

NOW the problem
3s lipo
5x5 prop great low amp but no thrust
7x6 Thrust 14 oz at 14 amp to much amps
08x43 Thrust 15 oz 13.5 amp WOT

Can some on just off the top of their head which way to go saying the props is the same style what length and pitch that might fall in to around 12 to 14oz thrust at 9 to 10 amp. BTW all the 3s lipo was at storage voltage the wind so bad here and no inside venue for me! All my lipos is at storage voltage.

Start with a gws 7x3.5 prop and trim the tips a bit at a time to drop the amps to what you want, or what is best for the motor..
It quotes 100W and a 10A esc so you need to keep it below 10A at 3 cells ...

an alternative choice would have been the 1300kv blue wonder with an 8x4 prop on 3 cells this gives 13-14oz thrust..
your higher kv will need a smaller prop ...

Love it Jose. The panel lines and weathering really make it. Really enjoyed the vid of your previous jetball. Looking forward to seeing the next one.

That reminds me back in the 70's I launched a hot air balloon made out of a dry cleaning bag with 4 birthday cake candles mounted on a balsa cross to keep it aloft. Launched at dusk on a summers evening it sparked numerous UFO sightings. I kept a low profile in fact this is the first time I've fessed up.

Jose that looks amazing!!! Great detail work.
I hope it escapes the RC law and never crashes...

Now I'm day-dreaming about it with same-color LEDs... (pink and green )
