Eflite Power 32 vs Rimfire & Dualsky 4250 vs Motocalc

Ive been looking at a motor for my 3.5lb 3D plane, and originally started by looking at the hackers, axi's etc. I noticed the eflite 32 was also popular for this size. After just a little bit of...

RE: To All ThunderBird ESC are Bad?

I run the same esc and 1320 3s on an axi 2212 / 2212 clone and it works fine. The power is a little lacking right now (0 degrees C ) compared to the summer though!

RE: Geared outrunners?

For any given prop diameter, using a gearbox and upping the pitch to make the current draw the same can be more efficient since the prop speed is lower so you get less frictional losses.

Geared outrunners?

I don't see many people gearing outrunners these days, though I see a fair number of setups like this from a few years ago.

I want to convert my saito 72 3d model (laser 3d) to electric. It is...

RE: Laser 3D Conversion

My wild guess:

AXI 4120/lots of turns
4s A123 2300 battery (enough for a 9-10 min flight, a 4600 is too big and heavy IMO)

Im not too sure about ESC, I would like a basic one like a...

Laser 3D Conversion

I am interested in converting my Laser 3D to electric. It weighs 4lb 6 oz, with a saito .72. Removing the motor, Rx battery, servo and full tank would save about 27 oz. Currently it uses a 13x4...

RE: Any reasons not to use a prop saver?

I think I will always be crash landing on grass :)

Also, my ESC will be set with no brake, so that the prop can flip out of the way.

RE: Triton Jr. false peaking

I have heard the Triton series deliberately undercharges a small amount as a 'bonus' safety feature, though it sounds like in your case something else is wrong.

Cellpro 4S Charge time vs. others

I am in the market for a lipo charger and balancer, and have heard great things about the cellpro 4S. I like that it includes a balancer, and I also really like that it can charge a lipo in 50...

Any reasons not to use a prop saver?

I've read all the threads about prop savers, but didn't find anybody giving a good reason not to use them. Several people said they were not required with the correct landing technique, but didn't...

RE: Brushless Outrunner Radial Mount vs. Conventional

I am pretty sure foam is strong enough to bend a prop shaft, even if the motor also comes off in the process.

The X-piece would be used in this case since I was planning on reinforcing behind...

Hi,

I am trying to decide whether to use the radial mount (top) or the conventional mount (bottom) for my AXI 2212. This is being installed on a 3D flat foamy (no landing gear.) My 2 concerns...

RE: Im on the fence, TP1320 vs Dualsky 1320

I guess not too many people use the Dualsky...

My final decision was Lipower Prolites from zebrahobby.ca. Apparently they are the same cells as TP but are a very good price.

Im trying to decide between these two batteries. I am getting a pair for a ~13 oz 3D parkflyer, with an AXI 2212/34 drawing 10A max.

Both have a 13C continuous rating (~17A). The TP pack...

RE: ESC Choice: CC25 vs Eflite 20

The motor is rated for 10A / 60 seconds, so I am also not sure why everybody on the www.3dbatix.com forum swears by the CC25 speed control, it seems like its overkill. They are all running 12x6...
