EMAC - Electric ONLY IMAC Events

[Bigroger]

Now problem Jim.

By the way, I thought the 9.5 min IMAC sequences were only once you got up to the high levels? You don't just jump in at expert level and go fly 9.5 minutes right?

The other thing, I thought you can safely discharge good lipos to 85% under load rather than the 75% as above? Thats an extra 10% of the flight time right. So if you could get 8 minutes that an extra 48 seconds maybe if you run it down to 85%.

I would like to resurrect this thread.

1. Are there any EMAC events still scheduled?
2. Is anyone else flying electric in any IMAC/EMAC event?
3. There is talk of allowing single senquence flights/twice a round, will this generate some electric interest?
4. What are the current size planes and power systems being used (also flight times)?

I started with an EF 74" Edge last year on A60, 12S and ran 3300 up to 4000 mAh batteries. The power was good and was able to compete fairly well, even with the smaller plane. I flew Basic. This year I fly Sportsman.

Mid year last year I built up an AJ Laser 93", with a Motrolfly 5335. I run 12S and Castle 160HV w/Fan. I have run 10,000 mAh and 8,000 mAh batts. I am about 23-24 lbs loaded. She flies well, but I notice the weight on power elements. For example, I can do a big upwing loop with no issue, but this years Sportsman requires a downwind loop, with a roll at top. When we have a stiff wind, I notice I cannot power into the top of the loops like my gas brethren.

My plan is to start requesting an exemption at contests to allow me to fly a single sequence at a time and cut my batteries to 5000 - 6000 range and lighten my little piggie up. I have the batts coming and will do some flights to see where I can comfortably do one sequence and be as light as possible.

Future plans... I want to get a bigger airframe. But, not sure what. I waffle between getting a 100cc frame and going all out and trying to power a 40%'er. If I did that I would definitely only fly it at single sequence events.

I would love to get a dialogue going and see who all is into this. I love the electric power system and I like to try things. I love flying Aerobatic Competition and I must admit that Pattern has held a little of my interest lately, because of the electric options.

I will also post some stuff at the IMAC site. But, I think this forum would get more eyes and interest. Especially since you don't have to be flying IMAC/EMAC to be interested in bigger power systems!

Are you thinking of going electric on the 40%er?

 

[Krzy4RC]

I would certainly consider it. I need two things. It must have plenty power, so that I don't regret it. Also, I would need to see that we are going to be allowed to fly single sequence so that the battery weight is manageable.

Nice, I'm currently building a 40%er and I have thought about doing it as an electric.

Right now, I'm also considering converting my EF 88" Edge to electric.

Would anyone mind if I move this thread to the IMAC subforum?

 

[Krzy4RC]

Sounds good to me. Its a very old thread, just some new interest!

 

[Notorious B.E.N.]

I'm game.

Talk to the CD of the contest. One sequence rounds are at his discretion. There's a contest coming up in the SC at the end of July that would make for a good chance to try it. It works well at the CC events, and as long as the contestants get in the air quickly and on time you can get in pretty much the same amount of sequences. At the 2014 Worlds NC/SC fly-off we got in 9 known rounds and 2 unknowns in the standard 1 1/2 day contest.

Don't worry! I plan on putting the screws on Cam to get me an allowance to do that! But, before I build a 40% and electrify it, there will have to be a more permanent solution!
