New Toys at the Field 🙂
With the advancement of technology in our hobby new items are coming up all of the time. I thought it would be interesting to see who’s using them at our field and how they like them.
One of the newest toys to show up at the field is the big Carbon Z T28. We have been having a lot of fun with them so far. They are very stable (has a gyro) and will land at a walk. With all of the components being equally matched from plane to plane they make a great plane to fly formation with. We’ve had as many as 5 in the air flying together! If you’re interested in one. Ask any of the guys to check it out.
I’ve been using a new charger. With more planes going electric and higher voltage and mah batteries required to run them I needed a charger with a higher charge rate. After looking and considering price/value and revues I decided on the Hobbyking Reaktor Charger. It will do 2 packs at a time or 4 packs if you charge 2 in parallel. It will charge at 20amps as well. So far it is working great. You just need to be sure and use a power supply which is able to supply enough amps to power it… Here’s some info from the HobbyKing site.
With 2.4 it is advised to switch away from the 4.8v receiver packs so most have gone to either life for lipo technology. Advantage of life is you don’t need a regulator, is stable and wont blow up, has a high C output, charges fast and it wont burn out regular servos. Advantage of lipo is quick charging and high output and with the right servos it is very fast. That being said I’ve chosen the life or A123 and have been running them for a long time now. The charging technology is different and can be a little intimidating for someone only familiar with nicad or nimh batteries. I’ve been using a VERY simple and reasonably cheap solution that i really like and even noticed some of the jets guys using the same setup at Miss Jets. FMA which I think partnered with revolectrix http://www.revolectrix.com/ makes a simple, safe, fast but versatile charger. I have an earlier version called the cellpro but they’ve updated it now to be the cellpro multi4. I use 2, 1 set for lipos and 1 set for life batteries. You simply plug in the battery, walk away and wait for it to beep telling you it’s charged. It automatically goes into balancing the pack and the end of the charge. VERY nice and easy! But it’s much more versatile if you want to take a little time. Even configurable with your pc PLUS it’s very small! If you want to check it out, get in touch with me and I’ll show you how easy it is. Here’s some info from the site
