I have a UCD 60 that I want to convert to ele. Has anyone done this? I have a Actro 24-5 that I'm told will work, but I would like more opinions from other people.

The UCD:
Wing Span 65"
Wing Area 1024 Sq In
Weight 7-7.75 Lbs

Actro 24-5 Motor Specs:
16-28 Cells
Resistance mOhm 62
Rpm's/V 435
Max Eff. 91%
Max Current 40-60 A

What Lypo battery pack is needed?

I'm not good at 3D, but I want enough power to learn more.

I converted a UCD 46 some years back on a Mega 22/30/2 geared. Times have sure changed in technology.

What about using an E-flite 90? Rated at 1800 watts. That would be over 200w/lb and great performance. Pluse the ease of using an outrunner.

Hi Mike,..................Yea I've already got a motor,....an AXI 4120/18. And 6 Lipo cells comprising of a 3.7amp 4 cell and a 3.7amp 2cell pack. I've been using this gear in a Cesnna trainer. (I'm new to this game of rc flying machines!)

I'm wondering if the above gear will be suitable for a UCD 60 and also how easy would it be to arrange the batteries vis CoG and for their easy removal/replacement.

Do you have any thoughts on the idea???

I have the 4120 Axi that is a lightly highr kv than yours, and it's a good motor, but can only put out around 7-8 pounds of thrust. This will definitely fly the UCD 60, but you aren't going to have enough power for good 3-D work. The bare minimum I would say is something equivilent to a 4130/16(E-flite Power 60). On 6 cells and a 16-17 inch prop you'll get a lot better performance. Ideally you'd want to go with something closer to the Eflite 90. Most of the guys I know fly the UCD with Saito 100-125's, and the Power 90 has similar performance. There are plenty of chinese knock-offs of the 90 size electric outrunner, you'd just have to compare sizes and kv ratings.

As for the CG, you'll probably come up nose heavy. Again, every one I've seen at the field with a Saito has at least an ounce of wieght stuck on the tail.

Well that's very interesting info. Thank You very much.
I've already fitted the 4120 motor. I'll see how it goes and bare in mind your coments.

Once again Thanks.
