Hi John!

I am assuming this is the large 55 inch wing span model and if you visit Hozion Hobby Web Site they provide a very good recommendation:

Thumbs up Very Good Power System (Himax HC3516-0840)

According to the Fun Cub User manual it shows in the mid 20's for AMP Draw:



I used an on-line (P-Calc) estimator using the Himax HC3516-0840 Motor parameters and it comes very close to what the Fun Cub's User Manual indicated while swinging the 13 X 4 Prop and using 3-Cell Li-POLYs!

Thanks guys,

I was hoping to buy the motor and ESC at my local hobby store. I am going to bring the specs to that they can help find a close match. I am only familiar with Eflite motors so this is a new venture for me. I sincerely appreciate all your help.

John,

I am familar with E-Flite motors as well and to get an Outrunner Brushless in the size of 35mm diameter and 16mm long with 840Kv (high Torque) will be hard at best because the one that comes close is the E-Flite power 32 but, it tips the scale at 7.0 oz.

Himax motors are very good but, I am sure your local hobby shop will set you well.

The price for the "Power Pack Set" that Horizon Hobby is selling is a very good price

Best of Luck!
Carlos

Default Someone left one Review!

John,

Over in the Horizon Hobby web site, someone left one review of your model and this person used HACKER motor and you can read up on it at:

http://www.horizonhobby.com/Products...243#reviewsTab

If you have trouble seeing this review then, here it is:
================================================== =

Not just a trainer, more advanced pilots will love this kit. It builds easy flys great...loops, rolls, inverted, hover and knife edge. The Fun Cub can do it all if built with the right power plant. I used a Hacker A30-12L with a 55A esc. and 13x6.5 Prop. Be sure to add the flap option for super slow flight, take-offs and landings. I have used it for light aerial photography and fun video. Can't wait to get the float kit and fly it off water. This is my new workhorse!

Default Hacker Power A30-12L with 13 X 4 and 3-Cell Li-POLYs

HACKER A30-12L power with 54-AMP ESC and swinging the 13 X 4 prop using 3-Cells.

Lots of Static Thrust!!

AMP Draw is up there as well....

Your choice, depending on what you are looking for in Flight Characteristics / Performance!

I was thinking a Park 480 or Turnigy 3530 motor.

I am sure it is a proven power system assuming you can have a correct Center-Of-Gravity using such a light Motor.

Looks very good!

Default fun cub power

I have a Turnigy C3542B 1250 kv outrunner laying around that I would like to put in my fun cub when it gets here. Is this motor a little big or should I stick to a lower kv one?

I also want to use a Turnigy Plush 40+ esc I wish to use. Is a 2200 mah 20 lipo the wrong one to use also.

Does anyone see any problems with this setup.

Default fun cub power setup

A good combo for the Multiplex Fun Cub is listed below.

A couple of the guys where I fly are using this set up including myself as I just got my fun cub finished.

1. E-Flite Power 10 1100kv outrunner. You will have to take the motor apart and push the shaft thru till it comes out the back side. Take your time doing this and do not use a hammer. The hole spacing is 25mm and that is what the mount on the fun cub has.

2. Turnigy Plush 40+ bec esc.

3. APC 11x5.5e propeller.

4. Two of us are using the Zippy Flitemax 3 cell 11.1 volt 2200 lipos. These come with the XT60 yellow connections. You may have to solder this type female connections on this battery if you use this one. The choice of battery is up to you.

Remember this is not a hotrod plane. It is meant for easy slow flying. Its your call ok. Just my opinion here.
