CMP C-160 Transall Electric Conversion
1 Attachment(s)
I have the CMP C-160 Transall Camouflage 2x25 - 72" ARF Nitro Gas Radio Remote Controlled RC Cargo Plane and would like to do an electric conversion. Nitro Models shows a picture of a Electric CMPro C160 in flight at the recent Swan Hill electric fly in. I would like to know what electric equipment was used for this conversion. Or if anyone else has converted this model to electric please let me in on your experiance (equipment used, flight performance, flight time etc.).

RE: CMP C-160 Transall Electric Conversion
Good Morning
I just saw your request for electric setup information for your Transal 160. I would be happy to give you all of the data I used successfully when I converted mine to electric. It flies great and only took a few changes to make everything work. Feel free to contact me to discuss the items. |
RE: CMP C-160 Transall Electric Conversion
Adrenaline1,
I'd also be interested in what all was involved in your Transal 160 conversion. Can you post your modifications along with what you went with to power it? Any pics would also be nice. Feel free to email me anything is you prefer that method. Thanks, |
RE: CMP C-160 Transall Electric Conversion
I will be happy to do it for you. It will take me a few days to get some pix and write everything down. The biggest problem was getting the motor mounted far enough forward to have the prop clear the cowling. I worked out a very simple way and it works great.
I will post something by next week. I am new to this forum and am not sure how all of this works but I will figure it out. |
RE: CMP C-160 Transall Electric Conversion
Thanks a million adrenaline1. I can hardly wait for your post.

To everyone who is looking for a successful electric conversion for the CMP Transal C-160 I am attaching the following data. Please feel free to contact me with questions
The following photos show the process I took to build my C-160 Transal with electric power. I was very happy with the results and the aircraft always gets great comments wherever I fly it. The sound of both engines in sync is sweet. Here is the parts list (2) Engines = AXI 2820/10 Gold Line part # 282010 (2) Motor Mounts = ACC3640 Motor Mount for 35mm Outrunner Order from www.maxxprod.com listed under Electric Plane Accessories page 4 of 4 (8) 6-32 x 1 ½” socket head screws to mount engine mounts to their bulk heads (8) 6-32 Blind Nuts (2) ESC = Castle Creations Phoenix-60 Brushless ESC (2) Batteries E-flite 3200mAh 3S 11.1V 20C LiPo, 13AWG EC3 part # EFLB32003S (2) APC Electric Propeller 10 x 5e (1) 6” x 6” x ½” plywood for motor mount extensions (1) 2” Diameter Hole Saw. Used to cut the motor mount extensions from the plywood. Note: The black wire tie around the wooden spacers simply holds the engine wires in place. (1) Small bottle of “Gorilla Glue” used to glue the 2 round plywood pieces together and glue that to the bulkhead. Only use a small amount of glue because it expands as it dries. (10) Small Rare earth magnets. Radio Shack carries them. They are used to hold the 2 lower engine cowlings in place (4) 1’ diameter metal flat washers. Used with rare earth magnets. (1) piece of ½ “ x 1” long sheet metal. Used to form the forward magnet base. (1) roll 1” mounting tape. Used to hold the magnets. One additional note; I suggest you re-glue and/or reinforce the forward bulkhead that the nose gear attaches to. The 1 in my kit was not glued properly and collapsed on my first landing. I hope the attached photos will be worth a thousand words. Good luck with your project. It is definitely worth the effort. PS: I am new to this and just found out my 11 photo files are too large for 1 upload. I am going to send the first 6 with this and then the last 5 in a follow up reply. I hope you get all 11. |

This is Part 2 of the Transal Electric Conversion.
The only thing attached to this reply is the last 5 photos I could not get into my last reply. Good luck everyone |
RE: CMP C-160 Transall Electric Conversion
adrenaline how bout a few pics of the whole plane. I really like this plane a have been thinking about making this my next build!! Thanks for all the info!!:D

RE: CMP C-160 Transall Electric Conversion
I will post some stills later but for the moment go to the youtube site below. You will see a 6 min. video of an electric conversion from 2006 which uses the same engines I did. The plane looks greatest when it is landing.

RE: CMP C-160 Transall Electric Conversion
Hi all,
I'm starting to build the CMP Transall / electric conversion. My set up: 2 x Turnigy 25-36 1300kv 2x 9x6 apc prop 2x Turnigy Plush 40a esc 2x 35-35 motor mounts The distance between the firewall and the tip of the nacelle is 10cm. Using the 35-36 motor mounts (5,5cm) is a perfect fit with the moto installed upside down (opposite side of the outgoing shaft). These motors sould develop about 37 amps WOT and nearly 400 watts each, for a total of 750 watts and a ratio of 130 watts per pound. I am confident it will be enough to have scale-flying fun with this plane. Philbel |
RE: CMP C-160 Transall Electric Conversion
I recently found your setup and that prompted me to go ahead to get the Transall C-160. Are there any more tips or tricks that you would wish to share before I begin my build? BTW I hope to build retracts and an opening rear cargo loading door. Any ideas there?

Are these pictures the same C-160 from nitroplanes for sale 134.99, it is CMPPro C-160 EP-Powered Twin-Engine RC Scale Plane Almost-Ready-to-Fly? Here is the link: http://www.nitroplanes.com/c-160-rc-plane.html I just ordered this plane yesterday. I may need help alot from you since there is no instruction how to build this bird. Thanks Jason |
RE: CMP C-160 Transall Electric Conversion
Nope different plane.
The CMPPro 160 is a perfect candidate for a pair of Monster Power .25 electric motors, Volcano ( or other ) 60A ESC's, a separate BEC, a pair of 3800mAh 14.8v 4S LiPo's, and a pair of 12x6E or 12x7E props ( preferablly one pusher prop to permit you to set up counter rotating props! ). |

RE: CMP C-160 Transall Electric Conversion
Battery Eliminators on MOST ESCs are "analog", not switching mode.
That means that the higher the voltage the LESS current output they can sustain before blowing out. That is why most analog on board BECs are rated for NO MORE than 2-3 servos at 11.1v!!!!! By the time you up the voltage to 14.8, the on board BECs are all but worthless if not dangerous! A few more expensive ESC's feature switching mode BECs, which can take higher voltages. But normally a premium is charged for these ESCs. Most manufacturers forgo the BEC's altogether for the higher voltages and only provide the ESC function. Standalone BECs are fairly cheap ( $9.00 - $18.00 ea ). I normally will either power the servos off a NiMH pack directly or I'll use a seperate switching mode BEC. At times I've also taken smaller LiPo packs that don't sustain the draw I want ( say that they don't produce 20C, and instead 12C when tested ), put a BEC on them, and use that to power the electronics via a BEC. This is normally very reliable, as if either of the ESC's ( or both! ) burn up, or get shorted, I still have control of the plane. |
RE: CMP C-160 Transall Electric Conversion
BTW: the Advertizement lists 25A ESC's...
There is no way you are going to get adecuate power for this plane if your max draw is only 25A!!!! |
RE: CMP C-160 Transall Electric Conversion
Thanks opjose,
Have you take a look at nitroplanes website. They also have a video of this plane and they put down their set up on the video as well. So, you are saying their setup is not right. Thanks Jason |
RE: CMP C-160 Transall Electric Conversion
It's easy to do the math...
11.1v x 20A = 222 watts at max throttle. 222 x 2 = 444 watts for both engines The stated weight of the plane ( always OPTIMISTIC! ) is 2.6kg, so 3kg is a more realistic weight... So 3kg = 106oz = 6.625 lbs 444 watts / 6.625 lbs = 68 watts per pound! This thing will BARELY be able to ROG at MAX throttle.... The plane in the video took off very quickly... So either they were overheating their ESC's ( and NOT allowing 20-25% overhead as you MUST DO! ), which will end up blowing them, or they mistated the specs in the video... My figures above are OPTIMISTIC as 3S LiPo packs typically only produce about 10.6v under load.! |

They are listed Hyperion HP 2213/16 and I have problem to find them. They are discontinue. Very appreciate for your feedback. Jason |
RE: CMP C-160 Transall Electric Conversion
Hi guys,
I'm building this Transall and I will be using 2 x Turnigy 35-48 1100kv with 2 x 60a esc. Plenty of powerwith this setup. Philbel |

RE: CMP C-160 Transall Electric Conversion
It's the CMP transall c-160 that's been on Nitroplanes for some years now: about 5,5 lb weight. I've got the militray camo version
Wingspan: 72 inches Length: 53.5 inches All built Fiberglass Fuse Recommended engine size: 20~25-2c 26-4c Wing Area: 581.25 in?br> Fuel Tank: 100~150cc Propeller: 9X6 - 10X6 X 2 Spinners: 1 3/4" X 2 Wheels: 50mm or 2" X 10 |
RE: CMP C-160 Transall Electric Conversion
Jason,
I'm sorry... The plane you bought is the new MP electric version of the c-160... I bought it last week for 134 $ and I'm waiting for delivery. For this plane I will be using 2 x Turnigy 35-36 1100kv and 2 x 40a esc with 10x7 3-blade Master Airscrew props. These motors will deliver more than 350 watts each so it will be almost ovewrpower for the EP Transall. But better a little more power than not enough. Philbel |
RE: CMP C-160 Transall Electric Conversion
ORIGINAL: whatala Thanks very much again opjose. So, what do you recommend for the motor for this plane? They are listed Hyperion HP 2213/16 and I have problem to find them. They are discontinue. Very appreciate for your feedback. Jason I would use this motor: [link=http://www.nitroplanes.com/mo258brmo.html]Click me![/link] Though Nitro is out of them at the moment, they seem to frequently restock them. I purchased 2 of them and 2 of the Monster Power 32's a couple of weeks ago. I would run two 14.8v 3850mAh LiPo packs one for each ESC. I would install two 45A+ ESC's. Why 45? As you increase the voltage to 14.8v, the total current capacity drops, so purchasing a 45A+ ESC assures you will not blow up the ESC. Then prop the system to pull about 37-40 full throttle. That will give you about 550 watts per motor. That's 166 watts/lb so you have plenty of power and great flight times! |
