Is any one doing or flying the new Hangar 9 1/4th Piper J-3 Cub ARF -- Wing Span- 106 in?

There is a thread on one but I think not here in giant scale---try elec conversions

hermperez · Oct 05, 2007, 09:35 PM

That setup from BP with the 10s2p A123 pack should work well, probably with a 19"-22" prop.

Most of these large 1/4 scale Cubs are seldom flown at full throttle.. 1200 watts of power would be fine for them.. you can save some weight by going with a 4130 class motor and 8s2p A123 pack. An 8S A123 pack is about equivalent to a 7s lipo pack. In terms of gas, about a zenoah g26..

This motor:

with a 16*8 prop, plenty of power.

The lighter you keep the Cub the slower it will fly.. more fun.

If you do a search in the conversion area i did one a month ago..plus onboard video

Thanks for the reminder of the other thread: http://www.rcgroups.com/forums/showthread.php?t=752795 .

I'm currently flying the older H9 80"/5th Cub on A123-5S2P & AXI 4130/16 via a 16x8 -- pulls less than 30amps; so nice long flights and very fast recharge!

I've previuosly had 16xIB4200 w/15x8; would fly inverted out of site.

Shed nearly 3/4# going to A123s! Now RTF is 9#.

I like to do big props @ 30amps WOT; that's why I was looking at the lower Kv & hence larger motor.

8S would save the wieght of 4 cells since I'll do 2P; was likely going to use two DeWalt bricks straight ot of their plastic shell.

My Mastech 5020 will give me a 20amp recharge; we have AC at the feild.

TIA,

Jim

But it flies very scale and has no problem taking off thick grass .

Please confrim the size prop you are using w/7S and the E-Flite 110 BL?

Jim,

You have me interested too. Have you made any decisions about gear? What is the street price of this plane?

Rich

jrb · Oct 13, 2007, 10:51 AM

Hi Rich!

Haven't seen you in while, nice to connect up here.

Sky/Warehouse has it for $489; that's a really good deal considering all you get! It was $100 to put Robart like mains on my 1/5 H9 Cub -- the 1/4 come with them.

Worked of the list in the manual and added a Spektum module w/7ch RX for my 9303 and that's another $480.

$200 for two DeWalt packs; and still haven't settled on a motor.

Seems "cheap" to get a Tower Pro/Balsa Pro for $100 when you consider all the above?

Quality & efficeincy speak to me for this project; but not at $400, still haven't found a Neu or other that I like either.

Do you have an idea for a motor?

Jim

PS: plan to go to TVRC mid pm; will have my 1/5 Cub on A123s there, FreeStyle on A123s, and not sure what else.

hermperez · Oct 13, 2007, 11:24 AM

A Cub does not need a lot of power unless you are flying from water or towing sailplanes.. an Axi 5330 series would be a nice motor for this plane, efficiency in the mid 80s and nice european quality. With two dewalt packs you would get 16 minutes of aerobatics and much longer just put-putting around. Prop it for around 1400watts.

You could also get a 5330 clone from UH for about $45.. in looks, functionality and build quality it is the same.

AEROLIPE · Oct 13, 2007, 02:53 PM

how much you pay for all?!

jrb · Oct 15, 2007, 09:02 PM

Got one from Hobbytown in Brooklyn Park today Rich; $460.

Jim

Ron · Oct 16, 2007, 03:09 PM

I see Axi has redesigned one of their 5320 motors for 6 lithium cells, and it looks like it will fly this model with ease.
check with Richard at www.pacificmodels.ca
it shows in the axi motor finder on their site, but doesn't come up when you ask to see the setup. I do know that they have one or two in stock for " testing" so a call to him might clear it up for you. I think it's what I am going to try on this model.

jrb · Oct 16, 2007, 04:04 PM

The HiMaxx 6332-230 ( www.maxxprod.com ) is at the top of my list of motors – has anybody used one?

jrb · Oct 18, 2007, 02:51 PM

Have finalized my set-up; all big ticket items are on there way: two DeWalts via eBay & motor via EFM, one of local good guys. The RX, extensions, & long arms should be here soon too.

So here what the list on items not in the manual:
RX: JR R700
ESC: Kontronik 3SL40-14-32 (40amps & up to 32NiCd)
HV UBEC
Pack: A123-10S- two so fly either 1P or 2P
Motor: HC6332-230 from HiMaxx/Maxx Products
Prop: APCE 16x10

I extended the HiMaxx motor performance chart to my area of interest as shown below; have included their data sheet too.

Rather than more normal “loom” I’m thinking about adding a regular Sermos/Power Pole set of connectors to the fuse holder, all wired with 13ga.

This will let me go to 20amps for recharge via my Mastech 5020; my 1/5 Cub loom is limited to a 10amp recharge with the 16ga wire.

Don’t know when I’ll crack the box open; will likely be worked on through the TG/weekend – maybe fly 1st part of December – my Mustang was maidened in December!

Below are some statisitics on the new AXI 5320/18 motor from their website (www.modelmotors.cz)

No. of Lipol, Properler, RPM, Volt [V], Curr [A], Power [W], Effic [%]
6s APC-E 16"x8" 6900 21,6 46 994 85
6s APC-E 16"x10" 6800 21,6 48 1037 85
6s APC-E 17"x10" 6600 21,6 56 1210 83
6s APC-E 18"x8" 6550 21,6 58,5 1264 83
6s APC-E 18"x10" 6350 21,6 69 1490 80
6s APC-E 18"x12" 6200 21,6 78 1685 77

I have Hyperion 6S 5000 packs (20C). Any opinions on this motor and battery combination on the 1/4 scale Cub?
