Default FuntanaX 50

Hey Sal,

I am strongly considering converting a Hanger9 FuntanaX 50 to electric. Can you tell me if this setup sounds like it would provide 3D power? What prop should I start with? Any guesses on expected runtimes? Should I go with 6000mah?

FuntanaX 50 using the E-flite Power 60 motor.
CC Phonix 125 esc (I know its overkill but would it hurt anything? I may go bigger later if this works out.)
6S2P 4200mah lipo pack.


Specs
Wing Span: 56 in (1422mm)
Overall Length: 56.75 in (1441mm)
Wing Area: 714 sq in (46.1 sq dm)
Flying Weight: 4-4.5 lbs (1.8kg-2.5kg)
Engine Size: .32–.46 2-stroke; .40–.82 4-stroke
Motor Size: Motor (for electric conversion) E-flite Power 60 brushless outrunner (EFLM4060A)

Thanks

The Funtana X 50 should do fine with this motor and battery Combo. The Phoenix 125 will work fine with this system. It is overkill but the only downside is that it weighs more than say a Phoenix 60 which will work in this system.

Based on a 20 c 4200 mah Li-Poly battery pack I figure that the aircraft will weigh somewhere between 68-75 ounces.

I get this:

Power 60
Kv 400
Prop: 16 x 8 APC E
amps: 48
thrust: 140 oz
Prop speed 50 mph

This gives you plenty of power for 3D flight...around 2-1. The prop speed is good and the amps at full power is very reasonable.

Here is another example:
HiMaxx 5030-380
Kv 380
Prop 16 x 8 APC E
Amps: 50 amps
Thrust: 154 oz
Prop speed: 52 mph

I would go with good 20-25 C batteries. Typically Interland built batteries would be the ones I would choose. The distributors here would be PolyQuest, Poly RC., Tanic, Hyperion, TP, etec.

Since the 25 and 30C batteries are just coming out, I would try to find these for sale. If you are buying a 20C, I would wait a little bit if possible as the price on 20C batteries should be dropping.

Thanks for the valuable info. Any comment on expected runtimes if most was done at 3/4 throttle just sport flying.

That would depend on the battery. The capacity and manufacturer affects this. I would say that with a 4200 and an airplane of 70 ounces the cruise time is about 24 minutes. figuring in aerobatics and proper discharge to a maximum of 75% of the capacity. You should be able to work with 12-15 minutes.

The best way to determine the flying time for the model is to NOT RELY ON THE CUTOFF! This is too hard on the battery. You want to only go to a max of 75% of the capacity. So fly it for 10 minutes forst with a good broken in battery and see how much you put back in when you charge it.

Let's say you have a 4000 mah battery pack. The max you want to take out of the battery for best care and longest life is 3000 mah. So you fly for 10 minutes and for example, you take 2500 mah out of the battery. Assuming that you fly pretty much the same way everytime, I might go to 12 minutes and see how much you take out then.
