Few question for knowledgeable persons

Hello everybody,
I fall in love in the F3P flight style. it probably because i am flying an F3A models.
I have dug a little bit and finally ordered Symmetric by DD.
also i ordered the next setup:
-Motor: AXI 2203/52 Motor
-Servos: JR290G, JR 188, Hitec 5035HD - they all digital...
- ESC: Castle Creations Thunderbird-6 Brushless Speed Controller (TB-6)
-Battery: ZIPPY Flightmax 180mAh 2S 15C

I need a feedback to this setup- does it enought and wil give me good aerobatics quality?

Few question to you:
1. Which battery capacity should i need? where can i buy it? there is a specific battery to F3P plane? (It's actually three questions)
2. which propeller will give me the best performance: 8X4 or 9X3 ? and where can i buy a light carbon prop that match to AXI 2203/52 Motor?
3.15c battery anought for AXI 2203/52 Motor?
4. what is mean "Static Thrust"?

thank's

Question #1a, b
a.Thunder Power(aka TP) 350 25c, or TP 325 65c. b. Horizon Hobby
Question #2a, b
a. The 8x4 would probably give more thrust, but the 9x3 would be better for F3P. b. See the attachment
Question #3
Unless you can find a really light(10-14 gram) 350mah battery, I would go with a 25-65c TP.
Question #4
Static thrust=The measured thrust produced when movement is prevented.

Hope this helps,

Nadav a Hyperion 180 pack is more then enough for F3P flying and the AXI setup, and the easiest way of saving weight. Have a look her for Indoor props http://foamtoair.f3ascore.com/glavak...24.10.2011.pdf

I use the 2203/52 in my current F3P league plane. 2s 180's more than enough. I can fly the schedule twice and a bit. Better to have more short flights than less long ones as weight is your enemy. Packs are cheap enough.

I use a Glavak 9x3. You will be flying on the prop. Big low pitch prop giving you the thrust you need at slow speeds and maximising your downline braking. Unlike indoor freestyle or even F3A you will have very little momentum.

I fly F3A but love F3P even more. Andy is one of the top UK indoor aircraft designers as well as organising the Indoor Masters. I think he must have tried almost every motor, prop and servo on the planet as well :-)

Remember that the DD Symmetric is a big plane and is not 3.5 oz RTF, from what I have heard something like 4-4.3oz. So a 180 might not be enough? BTW, which 180's do you use? Eflite? HK?

Thanks,

I use the Hyperions as well. Small, light and no balance leads. Easy to reduce weight a little as well.

Donatas uses 180's for practice and 130's for competition from what I remember.

Mejzlik do 9.5x3 which Gernot uses. Paul at Electricwingman has listed them. I might give one a go when we start indoor again.

The Mejzlick Indoor props are very good Dave. I used the 8x4 a few years ago on the axi race. There not as light as the Glavaks though but well worth a try especially if your a little tail heavy

thank's for answering...
more question.. :
1. what is the diffrent between propeller with slim blade and normal blade? in Symettric aircraft with Axi 2203/52 Motor what should i choose- 9X3 slim blade or 9X3 normal blade?
2. How do you connect the Servo to the plane that still remain stable : with Epoxy glue?, CA glue?, hot melt adhesive?
3. which adapter i need to buy that the Glavak carbon propeller will match to my motor (Axi 2203/52)?

To attach servos on my foamies, I use Hot glue and Foam safe CA.

I'm not sure which I had 'slim' or 'normal' :-)

There should be a 2203 adaptor available. Fits on the stepped Axi front end and is domed to fit in the back of the Glavak prop.

A lot of people use hotglue for some reason. I wouldn't on an F3P plane though as you need to save weight. Hot glue is far to heavy, only benefit is that it is quick.

I would never use hot glue on an F3P model either. Unfortunatley (for the sake of the servo case) for me the best way is to use Foam safe CA. Its the only way you get a truly rigid mounting for the servo without a weight penalty. UHU por holds the servos really well but not rigid.

The axi 2203-52 will easily cope with the 9x3 Wide blade. In actual fact it will happily turn a GWS 10x4.7. I experimented with a GWS 11" prop with some of the pitch twisted off but decided the extra weight of the prop negated the gain in breaking effect over the Glavaks
