Everyone please let me know if something here is not right. *edit* would i need the pheonix hv 45 or is the standard able to handle 9s? thx #2 Outrunner Himax HC5030-390, pheonix 60A ESC, 6s2p lipo for a total of 4200 mAh. This setup would be about 260 without the battery, which would be 33% more than the inrunner. It looks like they would be about the same price, outrunner would be a bit heavier, inrunner would have a little more thrust??? As far as flight times, I have now clue so any help would be greatly appreciated. Once again, let me know what you guys think about these setups. Thanks a ton for your help.

In option 1 above you will need the Phoenix HV 45 (hi voltage) in order to run 9S - not the standard P45 which is limited to 5S max.

The P60 and P80 standard esc's can run at 6S if you reduce the max amps by 20%.

ANY of the combos mentioned so far (and dozens of others) will fly the plane just fine and will do 3D - BUT - once again - weight is your enemy, so I recomend the lightest set up.

Long flight times and good 3D are contradicting requirements. The longer the flight time, the worse the 3D (because you will be heavier) and vice versa.

Option 1 will give you a LOT more thrust at a BIG weight savings. Thats an unbeatable combo if you want to do 3D. The outrunner motor AND the packs are both heavier. That adds up fast.

I'm not sure how you would go about making a pack.... I bought mine off the shelf. After 7 mins of solid aeros I am putting about 3000Mah into the pack. Weighty? My Fliton came in at 2.81Kg ready to go..... thats light by e-conversion standards.

I doubt the abilities of a 6S 2100 pack to provide the necessary 1kW... You are asking upwards of 50A (24C) from those cells...... IMO thats really pushing them..... Plus I doubt your duration would be flash.
Prove me wrong!

Well, i am planning on using a 9s pack, not a 6s, and I am also considering 3000mAh...I'll have to see. However, I want to keep it really light.

Your correct. The 6S TP 2100's are only good to about 850 watt peaks.

9S is a whole lot better

Ah 9S now we are talking.... you'd only need to draw 24A from those cell to get 1kW. Good stuff.

[Larry3215]

What ever setup you end up with - keep us posted.

There is a guy in my club flying one on an 80 4 stroke and it flys very well. A real floater too.

I definately will. I have Apex 3s 2200 packs almost brand new, so I think I'll get a third and make a 9s 1p 2200 battery. I think I am going to go with the option #1 listed above, and the all up weight should be in the same rough range as a .80+ sized four stroke and fuel tank, and the power should be better. Now i'm just tring to find a speed controller that will work with 9s because the Pheonix is out of stock. Maybe i;ll just wait until there back. I'll let you know when i get it going. Later

Ok, i just got the Pheonix HV-45 in, and now i have had a possible change of plans. I am thinking about going with a 12s 1p 2200 pack, the HV-45, and a funtana 90 or X100. Not sure on the motor, but Castle Creations claims that the HV-45 can handle the power necessary to 3D an 11 pound funtana. Any ideas about a motor? Thanks!

[Larry3215]

Any of the better inrunners will work fine a slong as they have a Kv around the 1000 range or a bit less.

12S you will see about 42 volts or so under load. If you motor has a Kv in the 1000 range that means its spinning at 42000 rpm.

A Hacker C50 16XL or a Neu 1515 2Y geared 6.7/1 will both do very well on 12S.

Im pushing my 1515 2Y to over 3100 watts flying my 15 lb GP Ultimate with a 22x12 prop. However Im pulling over 71 amps. You would need to prop down for the HV45 to be safe.

Medusa has a nice line of large inrunners and there is also Mega and several others.

I think i'll go with the ACn 22/45/3 (100ok/v) or 22/45/3E(800k/v)? Would this be good? I like mega motors because they seem pretty simple and they arent too pricey. Thx

[p sme]

And I assume that this one would be too small 22/30/4? Thanks again

[Larry3215]

If you go with a Mega Id chose the 22/45/3 - not the 3E. Your going to be pushing the mega pretty hard.

The Medusa 36-50-1000-5 is an even batter price and a little more efficient.

Your still going to be pushing the motor so cooling airflow is going to be important. Id even add some cooling fins if you can find them.

wow, the medusa does look very inviting, especially with the price. What sort of gearbox would i get with the MR-036-050-1000-5? I owe you bigtime Larry...Thanks!

[p sme]

also i see that the sell a heat sink for that motor...that would probably help with cooling...

[p sme]

Well I just got a deal on a really nice recovered funtana 90 with SFGs built in, and I'm picking it up this weekend. So it looks like its going to be the HV-45(I already have it), 12S1P lipo, either 2200 or 3000 mAh, not sure...any advice would be appreciated, and the Medusa MR-036-050-1000-5. Any comments before I take the plunge? Thanks!
