Raptor 50 3d conversion
Hi, I'm considering converting my Raptor 50SE to electric. My only experience with electric helis is a T-rex SE. I'm looking for a setup that can handle pretty hard 3d. tic-toc, piroflips, funnels etc. I was thinking of ttpacks A50-12S/Conversion kit Combo for the Raptor 50 with Phoenix HV-85 regulator. I have a charger that can handle 10S lipo up to 5000 mah. Therefore I was thinking of the FlightPower EVO 20 10s1p 3700 battery. Would this setup be too weak for 3d, or would it work? About how long will the flight time be (assuming full headspeed the whole way)? Or do I have to move to 12S? I'm not thinking on converting to eCCPM or anything, just using the raptor default with mCCPS. As you understand, I'm pretty fresh on electro so it would be nice to get some help making my raptor go ballistic

The motor and ESC you mentioned will be up to the task. You may want to consider a 10S2P, configuration. I say this because the 50 conversion is a bit heavy, so you'll need some serious juice to do the tricks you are wanting to do and the 2P will help give a good flight time. I would reccommend the CCPM conversion. I did it and it saves A LOT of weight. On 10S2P 4200 prolites I get 6 min of very hard 3-D without overheating anything. That is with an Actro 24-4 and a Jazz 55-18-32 ESC. I fly with guys running the A50 and 85HV and the power is comparable to what I run, can't go wrong there, especially for the price. You'll be pretty amazed at the power you will have running your rappy on 10S. If you don't already have, make sure you get a metal head block, because the torque will split the plastic ones. I've seen it and it is not pretty.

Thanks. I was looking on batteries and lest say the TP4200-10S2PP PROLITE, is that really 8400 mah adding the 4200 * 2 packs? It weighs about the same (924 grams) compared to the EVO 3700mAh 10S1P(951 grams) with half the capacity. And how do you charge these 2P packs?
I got two chargers capable of 5000 mah 10S each. Could I charge each pack of the two individually, like one pack per charger(4200 10S per charger)?
And how about the balancing? I can see the TP balancer having a limit of 5S. Do you balance the pack four times (like 5S each time four times)?

No that is 4200 mah, two 2100 mah 10S1P in parallel to get 4200 mah. You would need to get the TP210V balancer, each 5S2P pack has a 6 pin balancing lead. If you get the A50 12S, you need to buy 2 - 5S2P packs because you can't fit 1 - 10S2P pack between the frame stiffner and the motor. You will need to make a "Y" connector to put these packs in series. The Hacker motor is an outrunner, so nothing can rub against it. You put one pack where the tank goes and one up front. Thats another good reason to buy the CCPM conversion, you get rid of the servo tray not only for weight but a place to fit one battery pack. Buy a boom mount for the tail servo. The heli will fly totally different with the eCCPM from the stock TT MCCPM. With the eCCPM conversion you can go + - 14 deg, if you so decided to go that much. The Raptor 50 with LiPo packs and CF boom and struts and a lite weight canopy, you can get it to at least the same weight as a stock Raptor 50. I have a set up just like you have described except I have a Jazz 55-10-32 esc, I have a HV85 on another R50 and there isn't much noticable weight difference between it and my nitro Raptor. I can get 10 to 12 minutes of flight time doing loops, roles, inverted and FFF. Like OC Dan says, you can expect around 6 to 7 minutes.

Good luck.

Thanks. The only reason I didn't want the eccpm was because it's pretty easy to destroy the gearset or even the servo if you are unlucky in a crash. I'm running 3*S9255 so it could get pretty expensive, but I guess that's the only way to go. How is it to fly with the eccpm vs mccpm? And considering batteries, I was really thinking of FlightPower since I got an excellent local supplier. Could I connect two EVO 4350mAh 5S1P in serial and use and charge them like a 10S, balancing each pack individually?

The eCCPM IMO is much better than MCCPM, less linkage and just more responsive. If you are refering to the boom mounted servo getting hit in a crash or taring up the gears, that could happen with the stock set up just as easy. You could charge any brand of LiPo and balance them with two balancers.

Okay, I'm starting to understand it a bit better now. But one thing i'm wondering is how you do it with the power to the RX. The CC 85HV doesn't have a BEC. How do you guys solve that problem?

I have been using either a small receiver pack (1700 mah) on my drag race machines and a Duralight setup (4000 mah lipo) on my 3D machine.

I feel a lot better with a separate receiver pack in the heli anyhow.

Adds weight? - Yup but not a lot.

I also use small 2S or 3S LiPo pack and a UBEC for the RX power. Buy the UBEC from TPPacks, its a switching regulator and has the amps necessary for the servos.

I run a UBEC HV rated at 45 volts. Plug and play baby!

When you run packs in series it does not double the MAH of the pack, only the cells and voltage gets doubled. Running parrallel will double your MAH.

My 5S packs have a 5 pin balancer, not 6. Never seen a 5S pack with 6. No need for it.

The EVO's are a great way to go if you have access. Run 2 of the 5S 3700's in series for wicked power. I'll get a pic of mine to show you how to set up the packs for excellent balance and a great roll axis.

You will have no problems with the outrunners in the Raptor frames...plenty of room without anything rubbing.

I would be glad to see a picture
I have ordered the A50-12S conversion kit with CC 85-hv, UBEC and eCCPM now, going to order batteries soon together with some accessories like connectors, rear servo mount etc.
I was considering buying a Watt's Up meter for monitoring the performance and battery capacity. Is it a good choice?

A WattsUp is good, you could also buy a Data Recorder from Eagletree and then you can add temperature and RPM if so desired. The Data Recorder is $70.00 with USB Cable and software, the temp sensor is around $10.00 and the RPM is somewhere in that range also.

OC Dan, I can say how many pins your balancing plugs have on your EVO20 cells but if you bought them from Gary they have TP plugs and TP plugs have six pins. The balancing plug has to start with a ground wire then a wire for the positive of each cell, so a 5S pack must have 6 wires in the balancing plug for it to work. If a plug had only 5 wires the most cells it could detect is 4 and Thunder Power balancers don't have 5 wire connectors, just 4 pin and 6 pin connectors.
