The high performance connector of choice

Voodoo looks to be using 4mm long style bullets though. I dont see the point of expensive hard to get connectors (ie kontroniks in NZ )
How's the 6mm diameter do for fitting in the fuse.

Henke,
Check out the headline of this forum:

Aircraft Electric Airplanes High Performance


You claim to be the fastest?

Well, its hard to believe as your electric power hardly would exceed 100 watts.

I checked it, the official fastest in this category is this one:

http://www.rc-network.de/forum/showt...=1#post2505024

Its slightly larger than the swist, and i am pretty sure its got less than triple carbon, and i guess David got to solve larger problems than dremeling a fuse to get it at that speed!
Sure it is not out of the shelf but its actually the fastest,no question.

It scored 275 mph average in both directions at the official FAI 400m track,with calibrated measurement equipment under the eyes of official FAI sport witnesses.

I think there is a small difference to a simple gps or doppler reading shown above your avatar.

Its up to you to challange the worldrecord,get your swist into regulation and join the WR- trials this year!

@all
I would not judge a F5d airframe about how a wing fits to a fuse , the possibility to carry a turbine, a single radargun speedpeak or the amount of carbon layers in the wing.

If you want to compare airframes you have to watch only that part of the job which seperates the airframe-performance.

So take several airframes,add the same weight and power and compare speed, corner-performance and laptime.

I only saw the swist flying once (with a turbine), it was crazy fast but cornerperformance seemed to be a little poor(maybe for safety reasons) compared to the common f5d competition planes.
I never saw a swist in competition(why?)if i had the choice i think at the moment there would be several other planes ahead at the list but sure not because of fuse -wing alignement!

Regards
Yello

Thanks.

Two questions.

Is your ESC sitting on top of the 2S pack?
Are those 30C packs?

Yes,the ESC is wired so it almost stays up top on it's own,then the 2 cell goes under all the way up to the firewall almost (2700mah touches the firewall).....and another yes,those are 30C packs.

You say up against the firewall, I am guessing you mean up against the motor?

I am worried about cg.

He has a outrunner, so there is a firewall between the motor and the battery

Cool, that's my main concern. Don''t want to get two batteries to run in series unless I know it's going to balance. Seeing there is no room to move that batts

I didn't know you were currently running an outrunner on the outside.

If you use 1800mah 6s there is a lot of room to move them around cause the packs are small and it keeps the plane light (that is what I used in that July 4th video you liked).2200 still can move around a bit.2700mah my plane is a bit nose heavy but not bad,just makes it land a little hotter....at that point the plane is also getting heavy.....

What was your timer set for with the 1800mah?

About how many amps are you pulling on these inrunner/6s setups?

I would think 30C is really pushing it.

Good 1800 cells are able to handle much more than 30C continuous:

http://www.rc-network.de/forum/showt...=1#post2584469

The example shows average voltage of 3,42 V at 99 Amps, this is more than 2000Watt at 6S continuous without prewarming the cells.

With cell start temp of 45 even more would be possible.
A questionmark about the reliability!

My 1800's are 65C,they work great with the inrunner,but the outrunner sure likes the 2200's much better...C rating is bunk if you ask me.
