Raptor 50 Electric conversion

Just a few questions about the conversion.

1. How much do the conversion kits cost?
2. Is it an easy process to underake?
3. Is the the Hacker AS-50 Motor, Castle Creations HV-45 with USB link a good option to go for?

If anybody has done it themselves or know a little about it could you please let me know what you think?

Many Thanks in Advance

I think you should try http://www.tppacks.com, they have great combos for the raptor!

Are you on about the standard sort of conversion using the R50 frames, or going down the XeroG conversion ?

XeroG:

Have a look at http://www.realraptors.co.uk for more info on the 600ep from XeroG.(some more pics in my gallery)

Thanks, I am looking for Just the stadard conversion with the R50 frames,does it work out a little on the heavy side if i dont go for the Xero G conversion?
Many Thanks

Gary Goodrum has been testing his Raptor conversion kit with a new Hacker 50 motor. He said even without any weight reduction is was fully 3D capable. Not sure if that was with the Emoli cells or a standard 10s lipo. He posted several ways to save almost a pound using the stock frame and config.

Wakeboarder2342 has an electric conversion on his Raptor 50. I believe it is a hacker motor and cc speed controller. You should give him a holler. That thing has scarey power

flying ..... work .... sleep (pick any two)

the best place for the conversions is http://www.tppacks.com

i am running the following setup on my raptor50 conversion.


Hacker c50 19xl motor
Shultz 32.55 ESC
The box conversion which reduces the gearing 2to1
CCPM conversion, this saves weight and removes the servo tray
fiberglass canopy
mavrikk 600mm carbon blades
i am currently running either a 9s 3700's or 10s 3000's for batterys my headspeed is calculated as follows.


on 9s i get (855*33.3)/8.5/2 so i get about 1675 onthe head, when i go up to 10s i get the following (855*37)/8.5/2 so 1860 headspeed.


to be honest even thought it calculates at only around 1600 on 9s it climbs like a rocket and feels much more then just that!

i will be testing it on some emolis probably 10s in the near future just gotta sell some other batterys first!!

after having both electric and nitro raptor 50's i would say the electric is hands down better IMO. more power less noise and mess!

everything else is stock

the raptor that gary was trying out was using the A50-12s with 10s-2p and stock 85/10 gearing. here is the thread:
http://www.rcgroups.com/forums/showthread.php?t=493632

there are two nice videos that give a good idea of what you can expect from the setup. The batteries are not the emoli's. They are the Thunder Power Lipo's.

Gary's on top of his stuff!! Don't be afraid to deal with TPPacks. I have the Hacker A50-12S in my E-rap and it's great!!! not to mention more affordable as the motor is $150 and CC45HV $130. The ECCPM conversion and motor mount conversion is there as well for another $110 or so. The most expensive part is the batteries, as they usually are. Even the pricing on TPs has come down as well. Once you have the setup it won't be long and there will be new cells right around the corner that will be cheaper and better!!

If you skip me I can't play!

After studying these boards for some time, I decided to build an eRaptor from scratch - my first heli. I got a pretty good deal on a new 50 V2 kit from a going out of business hobby shop. Then I shopped around for a Neu 1912/1.5Y motor and CC Phoenix HV-45 ESC. I'll use NiMH packs (24 cells) until I get proficient flying. I have a mini-lathe and drill press, so I decided to make the mount and shaft adapter myself. The most difficult part was finding an M8 x .75 tap for threading the adapter (think bicycle tools). After all was said and done, it looked a lot like the TTPacks kit, which for $45, is a real deal. Unless you just like the satisfaction of doing things yourself, I recommend getting the kit. Installation is a breeze, although tightening the motor screws gets a little tedious in the confined space you have. Also, it would be nice if the motors came with flats for setscrews already machined on the shafts.

I'll let you know how it flys after I learn how!

The NiMH batteries are going to be a lot heavier. What motor did you use?

Stanc,

Thanks for the input. The batteries will be heavier, but I don't want to invest in the LiPos just yet. Ultimately, this will be a photo bird and I'll lose the NiMH packs when I add the camera equipment. I don't plan on any 3D flying, just heavy lifting.

I'm using the Neu 1912-1.5Y motor with a home brew conversion kit.

What kind of flight times do you guys get with these electric conversions? How long does it take to charge a lipo?

I have my timer set to 8 minutes and use approximately 75% to 80% of the pack.

The packs will charge to 90% to 95% capacity in about an hour at 1C. I always charge mine at 1/2C and it takes awhile longer, but I have several pack that I keep in rotation on the charger at the field.

What is the lowest voltage you run your packs down to and how many mah is used? Say a 10S5P 4200 mah pack, the voltage was at a little over 37 with no load and it took a 3300 mah charge. I have a micropower data recorder and it said the lowest voltage was 34 and the average was 37. Does it look like I took to much out of the pack for it to take a 3300 mah charge? I'll post the graft later.

stanc,

Even though the voltage you run your packs down to is a critical factor, I pay more attention to the mah that I use out of the pack. I try to aim for 75% to 80% mah used. I would fly for five minutes and recharge the pack to see how much I used. Then I fly it again, but this time I fly it for 6 min, recharge, then 7 and so on until I find out how long I can fly and only use 75% to 80% of the total packs mah with my flying style. Everyone has a different flying style, so this time will be different for most, so you will need to figure out what your average time per flight will be.

Doing it this way will increase the number of cycles you can get out of the pack over time. These packs are expensive, and I want them to last a long time. It's the same story when I recharge. I use a balancer and only recharge at 1/2C. The less stress you put on a lipo, the longer it will last.

If you used 3300 mah out of your 4200 mah pack your right in the perfect range. (3300 divided by 4200 = 78%)

Even if you don't use the 75%-80% rule as I do, these larger eHelis will always tell you when you've reached that dangerous low voltage area because your heli will loose power fast. LAND IMMEDIATELY. Lipos are great at maintaining constant power to the end. And then the power drops off like a rock. And even then, you will still find the voltage well above the danger zone. Personally, I don't recommend doing it this way, but some pilots do fly their lipos to the end of the power cycle.

Thanks for the info. I've not been using enough mah until yesterday, most of the time they take a 2000 to 2200 mah charge. So the voltage is somewhat critical but pay more attention to the mah.

You'll like the A50-12S Lithiumstatic. It's very close to a nitro 50 setup powerwise. I set my timer to 8min just like Chuck. You might want to check out the ECCPM setup Gary sells(TPPacks.com) for $70, it allows you to put your batteries up front.

If you skip me I can't play!

I think a few of the guys on the other forum are running 12S eMolis on the A50 with loads of power. And if the new firmware for the CC 85HV ESC is any good then the price to put an eRaptor together will be pretty reasonable. (Reasonable being defined as to what it cost me to put my other eRaptors together using lipos and expensive ESC's and motors.)
