Best electric IMAC plane?

[eajohnson]

Well, it's been a while and I had been waiting for Extreme Flight 88" Extras to get back in stock (just cuz the 3DH isn't close enough to scale), when a good deal hit me on the head. Looks like I'll be converting a H9 35% Extra 260 to fly next year. 15S/10000mAh and a big Hacker or Plettenberg motor should do the trick.

I have flown basic in 4 contest this year and last with a Aw extra 300 100 cc with a hacker A100 196 kv running A123 9600 and Neu 6500 11 s2p for basic. i have timed several guys in Oklahoma in sportsman and the flights are about 8 1/2 min from start to landing . I have tried and the most i can get in the wind in oklahoma on sportsman is 1 .8 Seq about 7.45 min. my plane is about 32 pds AUW on 13500 ma 11s2p Neu. if I went to 12 s3p 15000 i would add about a pound so 33 pounds and add 10% flying time so about 75 sec would be close. I am using :

AW extra 300 lightened
Hacker A100 196 kv
Mezjlik 27*12 TH
Spinn 200
Neu 11s 2p 13500
FAST 2.4
a123 1100 RP
Hitec MG digital

The 3DHS 103" Extra 330 SC with a Hacker A80 and 12S 10,000 batt comes in at around 26-27 lbs. It has plenty of juice for sportsman for sure. Mine, with a DA85 and Pitts came in at just under 23 lbs without any mods required.

Under 23 lbs. on this size plane is very impressive. Must be a real floater!

Any suggestion for a YAK or Extra 260 between around 75-78" wing span under 11.5 lbs. I would like to get one electric in this range. I fly Intermidiate.

I don't think one exists that light . . . .

3DHS makes a 70" Slick that is bigger than the wingspan indicates, It's around 9 lbs AUW electric with 6S 5000.

As for Yaks and Extras, EF makes them in the 74-76" range, which comes in somewhere b/t 10-12 lbs with 10S 4000. That's probably the closest to what you're looking for.

Yep, at less than 23 lbs, the 103" SC is the easiest 3D airplane I've ever flown. When I first flew this (my first gasser in such a long time), the hardest maneuver was landing, since at barely above idle, the plane would continue to fly . Anyone wanting to convert a 35% for IMAC should seriously consider this airframe.

Yes, I know about this one. It is not available yet. Thanks,

Pilot RC has 73" Yak you could probably convert. http://www.pilot-rc.com/ProductShow.aspx?id=79

one thing to note is most of the giant scale electrics i see competing are flown by sponsored pilots. large electric set ups are very expensive and you need a lot of batteries to compete along with back ups. my feelings are that lipos have a shelf life and used have no value so it is a very expensive choice in an already expensive hobby.

This one looks good. Anyone has experience with this kit?

Thanks,

Last year I competed unsponsored in IMAC Basic using an electric Hangar 9 Sukhoi 33%. The cost for the power plant was:

Motor - Turnigy 80-100-130 $150.00
Speed Controller - Turnigy K-Force 120A $220.00
Batteries - FlighMax 3 sets of 6S-4000 $65.00 x 12 = $780.00

Total = $1150.00

What does a DA-85 cost with pipes?

I flew the entire season on 3 sets of batteries and they still have all of their original snap.
I also use these batteries in other planes so it shares the cost.

But due very soon.... the week of Thanksgiving.

i think you can recoup most of your investment with all but the batteries. if taken care of as you have, lipos will last, but id bet you would have a harder time selling them compared to a used da 85. im not bashing electrics, there are just some costs factors i see imho.
