Logging
Weather permitting, I may sneak out this afternoon and put in a couple of flights to log some data before I leave for Clint's

flight
The Evo conversion now has five flights on it. Motor draws 24 amps in hover and a max of 73 amps in aerobatics. Looks like the 80 amp speed control is going to be adequate.

Conversion
I have started practicing F3C with this model. I can easily get through an 8 1/2 minute flight and put back 3500 mah in a 5000mah battery. The model is very smooth and generates a lot of power to make big maneuvers, too big if you're not careful.

Hi Gordie,

Now that you have the model pretty much wormed out, can you feel the force taking over and the addiction setting in? I know that it is a lot more of a headache dealing with all the charging, but as you gain time on the system and see what a reduction there is in parts wearing out, maintenance time, cleaning time and so on, it is well worth it. Having the wind switch directions on you upstairs will no longer invoke panic as you have the power to handle whatever comes up.

As someone who has flown electric for a long time now--starting with the original Joker with nicads/nimh it is interesting to watch you guys finally embracing the pleasure of electric flight. Who says you can't teach a bunch of old dogs some new tricks.

Congrats with your enjoyment of the model.

Hi charles,

We would have probably made the switch a long time ago, but batteries just were not there yet. We need real high capacity batteries to get the run time needed and up until recently they either didn't exist or were very expensive.

Uh Oh!
Wayne,
I only have maybe 10 flights on this model and Monday at the field I was working through "P" schedule (yes, I suck!) and one of the local guys was flying his Velocity 50 with an OS 50 Hyper that badly needs a rear bearing. I got so annoyed with the noise coming from this thing and then realized, all my models before this made that same (not quite as ratty) sound. I can see getting spoiled with this.

I left the hobby for 7+ years and when I came back it was with electric airplanes. After a few years I got the bug to play with helis again so I dusted off my JR Superio and took it out the field and had a lot of fun. When I came home I asked Laura, my wife "what smells so bad?” When she said it was me I thought back to the Cool Power 30% fueled cloud I was playing in as she sent me back outside. I haven’t played with the wet stuff since.

Wayne,

I know, batteries were a problem until the last few years. Price has been the big change. They were so expensive early on it was difficult to accept.

Gordie,

I know what you mean and it is amazing, after you have flown electric for a while the nitro noise does start to get a little annoying. I guess what I enjoyed more than anything was the no clean up. You just have to get used to lubing things more than with nitro.

Not exactly the best weather for flying today (cold and trying to rain), but I got out long enough to put in a full contest round on 8.818 . I'm really liking this set up. With sensible collective mangement that asks only for the 4000+ watts it'll easily deliver just before maneuvers, it's just slightly less efficient than the 9.5 I had tried, BUT the headspeed is staying dead nuts constant across the whole flight, esp in the aeros. Power out on the ESC runs between about 88 and VERY narrow and brief spikes of 100%. IOW, little or no "flat topping" of the power out curve. For me, this is a far better set up than the shorter geared 9.5 because I have a ton of power when I need it and for headroom, yet with judicious use it costs me little runtime. Oh.....the thing runs REALLY, REALLY smoothly with this gearing.

Have I mentioned how cool this all is ??

gears
9.1 gear is in the model and will be flown soon. I am looking for a little more power with still enough run time to make it worthwhile. I know I can get run time with 9.3 and 9.5 but a little more power would be nice.

9.1
I flew the 9.1 gear ratio at the Daytona Fun Fly and was pretty pleased. I was turning the rotor head really hard 2100 rpm plus and was asking the ESC for lots of power most of the time. I never exceeded the safe limits of the batteries but found when I turned the head speed down, I had the same power and speed but the ESC was not WFO all the time. The biggest change I notice is that pulls on the downwind legs are easy and you have to be careful not to make stuff too big, like the second loop on the Cuban eight. I was going to try the "D" schedule aerobatics but, since they are new this year, I don't have them memorized and couldn't remember them. If I get a chance to go out during the week, I will concentrate on getting through them
One additional thing I noticed. I had to go to 105mm TR blades on my nitro model to get the tail to work effectively all the time. Since the rpm on the E model is so constant, the 95mm TR blades seem to be more than adequate and require less power. i wonder if I could use the other TR pinion and slow the TR down a little so it doesn't "howl" all the time?
Another cool thing, I can load the data logs on my laptop and email them to Dr Ben so he can look at them at his leisure and then email me back and recommend changes.

Gordie,

Your models being Evo's already have the 18T counter in them for 4.77. No slower to go... .

You refitted them on the nitros for 5:1? That's really cooking at 2K on the head.

Yup!
I really liked the higher TR speed in a 1400 rpm hover but it really howls when upstairs. Since I am hovering at a higher head speed with the E model, I can probably use the lower ratio.

Hi Gordie,

My calbier's have always been 5:1. If you are planning on putting the body back on then I would not recommend slowing down the tail rotor. Just make sure that it is balanced extremely well. These new backwards maneuvers with a body are going to require a lot of tail rotor power. The electric motor helps a ton as it does not sag like glow motors do when the tail rotor gets out of line, but you still need ample speed back there.

Ben, Gordie,

I have been reading all of your posts on this forum regarding the electric stuff and I am starting to get a little concerned as I am sensing too much joy and excitement when you two talk about the way your models are flying. If we as a community don't step in and intervene, I am afraid that we will see you both in "electrics anonymous" and that would be a real shame. I am going to start writing out a ten step program that will help you guys learn to control this addiction.
