I was flying at a local airshow sunday and they had me and another heli pilot do speed runs. my trex 600 got 56 mph. The other heli pilot got like 66 i think on his trex 700. I was in shock when i heard this. I think i will try it again one day but put more pitch to the heli just to see what happens. what you guys think? By the way i think im running 10* of pitch.

What is your setup? ( If it's electric)

Try 13 or 14 degrees, if your machine is up to it, also try increasing the Rotor RPM

If you go up real high and dive with around 0 degree pitch then slowly bring the pitch in, everything needs to be smooth. My Furion Six did 75-80mph pretty easily. Even without a canopy

You need more head speed, and pitch as well. Before you add more pitch make sure your motor is up to the task. If not, it'll bog or you'll have retreating blades. My stock trex 550e went 78 mph in stock form.

Parasistic drag
People will be quite supprised when they see how difficult it is to get up to speed with a helicopter under the FAI format.

Most of the time a top speed is taken at the bottom of a dive with a radar gun and is only momentary. An average speed over a 200 meter course is compeltely something else.

Want to go fast?

I would have never thought 78MPH with a stock 550E would happen!

What i did was go up and dive the heli straight down at the ground to pick up speed then add collective to go arcoss the runway.I am going to raise my head speed and see what it does.

I go to a fun fly where we do speed run regularly, and believe it or not the fastest, over 100 on 700N with normal setup) is doing hurricanes, and when you come out of them you just get slung around fast.

+1 on Povern's comment. I get that 700n moving during hurricanes, I've been wanting to clock how fast it really goes.

really?

Will like to see it hold 100mph over a 200m horizontal speed trap.

My friend and me are going to try it this weekend. he's going to bring out his radar gun see what we get.

he has an he has a 700e and I have a 700n. I know the e will be faster but I'll report back here. (if weather permits)

if its windy from the storm coming this way I will try it and use it to my advantage.

I cant wait to here what you get out of it. Shoot i should find someone out here with a radar gun and do several passes. Do the 450, a 500, 600, and a 700.

well I can do the 450 fbl stock. I'll see if he will let me try it on a 500 stock as well.
I just sold my 600n but I will get to fly it this weekend after he sets it up on the new owners radio. maybe I can convinse him to let me try it for a speed run as well.

last OHB Nick Maxwell coached me on getting the hurricanes really moving. When he grabbed hold of my old 600n I thought it was going to rip in peaces. Then I got the High speed hurricane bug.

Just be prepared to take any radar gun results with a grain of salt. I've been radar'd a few times and the numbers were wildly different. At one fun fly a was radar'd at 56mph and everyone knew the run was far faster than that. Then just a couple of weekends ago another guy radar'd my Logo 600SE. I know it was cookin' but no way it was 150mph. I think that for some radar guns our helis can be difficult to get an actual reading on. Unlike an airplane there are parts of our heli traveling at the radar gun faster than other parts at any given time. I think the spinning blades may cause false readings many times.

Regardless it's all fun and a blast flying fast.

I can see where that is possible. I would do several passes and report each result.
I will also have him try with the Heli on the ground and the blades spinning. If i get anything other than 0mph we know the results won't be true.

Radar guns are really only accurate when held still...
