The harder part will be FINDING where to buy it.
eBay have a few sellers.
Plus there are a few car and boat places selling them. (Two in Aust)

How about the HET 3W-25? I using it on 5s for only 33A 650W with the CS10. Fly's the Lander Cougar very well. 6s should be easy

St.that setup work good with small lipo.? Is there away to use small low draw setups with good flight times? Say 800w 5s.1300/1800mah and lower kv 1300/1600 maybe?

fwiw, i would not go smaller than 2200 5's for 800 watts unless you want to fly like an old lady

i look at it from a realistic c rating stand point, 20 c continuous from a 40 +c rated battery is doable.

so 800 watts at 18.5volts is 43 amps . 2200 at 20c is 44 amps.

i have had setups that were well over this but have found that they only work well when the power to weight is massive and throttle use is limited factors other than my left thumb , like losing sight of the thing

Sure, if 800watts is all you're after the L2855 2100kv would be perfect. Very low amp draw and should be 100% reliable at that power level.

After 5750 posts I'm surprised there is anything left to say about any CS fan.

Huge difference, and why inrunners tend to be easier to set up. I'm yet to see a poorly balanced inrunner, even from HK.

Now to find an 1800kv inrunner to run this thing on 6s... anyone know of one?
agreed, i guess i have to stop being so cheap and by a inrunner i probably save at least 2 bucks an hour balancing these things

CS 10 blade in BAE Hawk converted to Control Line


Just when you thought there was nothing more to say about the CS 10 blade fan......

Some of you know about my project to convert the BAE Hawk from Hobby King to Control Line for my Dad, and use the CS 10 blade 70mm fan of course with the Turnigy L2855 2800 Kv motor on 4S. Dad only flies control line and really likes EDF's. He did a conversion himself with the F9F Panther from Hobby King, but it ended up to be a 3.5 pound brick. So I had to "show him how to do it". The Hawk is similar size and mine came in at 2.0 lbs AUW with 2.2 lbs thrust.

I shipped the Hawk up to him in PA, then visited last week to do final assembly and maiden flights. It was a great time!! Really - no kidding. Control Line of all things!

You gotta keep in mind that most guys who fly control line are "old school", so this was like bleeding edge technology. Here's the video from my visit.

The fan unit was not as balanced as I would like, but I was more concerned to just make it work !!

Derek - that was really fun to watch, great work with your innovation there. Even better, you did it for your Dad! Very cool!! The final par of the video with the helmet cam was great, but with the speed of EDF, you must have gotten dizzy. thumbs up!!

I've never spent more than 30mins on any fan, even the off center haoyes...

I could always get them to balance...

Make sure the rotor is static balanced too...

Thanks for the kind words. I'm gradually trying to make my videos more "interesting". The helmet cam was a GoPro on a headband. It worked fantastically. I also used the GoPro for all the "interviews". The 170 degree view of the lens makes it real easy to get everything in the shot.

For editing, I used Sony Vegas Pro 11. During the flights, I had 2 or 3 cameras running. The editing process to synch them up, then switch from one camera to another, is nearly impossible without a good editor that has "multi-camera" editing. I never tried the youtube editor. Each camera also has an audio track. Usually, I let the audio change with each camera view. At the end of the 4th Flight, when the Hawk landed, I kept the audio track running from the GoPro on my head, but switched only the camera views. It sounds like we are "mic'ed up" as I switch camera views. That's a new thing I tried on this video.

That was a big effort! Well done!
Maybe the only Control-Line CS10 in the world!

Gee... reminds me of the 'good old days'..... control-lines in the mid 70's....
Cox PT-19's..... and home-made flying wings etc.
