I've read many things about the correct or optimum head speed on the VE. I have a Astrp 020 upgrade in mine and with a very good Kokam 3S pack, I have a meter that's reading 1620rpms at fulll throttle and 44amps Static. This Astro which is Astro's upgrade for the VE is only good for about 45 amps max. I'm using a 16T pinion.

The most common recommentdatio that I see is for a head speed of around 1850rpm's. Does anyone else have this setup?
What size pinion do you recommend.
Is this Astro just too whimpy for what you need ei. C40T or A30-10xl?
I'm trying to stick with 3S but it's looking like that may be difficult. Anyone have experience with this?

Thanks

That's probably the optimum and max speed for a stock voyager head without upgrades to thrust bearings or to a completely new head. I'm running a Voyager E on 4S with a calculated headspeed of 2000rpm and it has a Quick Japan all aluminum head.

Once again I agree with ScaleCrazy. 1800 or so is the sweet spot for the stock head. 3s and 16 tooth is also right for that set-up. I also run the Quick of Japan head (makes it a totaly new machine), but I also did the stretch and run 470mm blades with a hacker C40 with 17 tooth Pinion, and 3s3p 6000 TP packs. Been flying this same machine over 3 years now, and for what I do, it's just fine.

Hey Thank you very much guys.
do you think its safe to fly this at the speed I'm getting now which is just over 1600rpms? I'm just training on it, not doing anything more advanced yet.
DWOEL:
Are you using the Astro 20 setup? That's what I am using but as I said am seeing 44amos static and only about 1600RPMs.

Is there a thread on the stretch of this?
Anybody have a pic or two?
I conicidentally tried to get hold of the Quick Distributor yesterday to talk about a new motor and upgrades.

I think that I would upgrade to the C40(or something like it). By the way do you know the difference between the C40T and C40H? I think it means more than just Heli or whatever.

Thaks again guys

I think you'l be OK hovering a bit and learning to handle the VE at that speed. I will caution that as your battery begins to drain and the headspeed drops you will get dangerously close to the infamous VE wobble.You don't hear much about this anymore with all the mods and higher headspeeds. At approximately 1300 to 1350 rpm headspeed the VE begins to wobble and oscillate. This will increase until it becomes uncontrollable and you will crash. If you see tha wobble start, LAND immediately. It seems to be an internal resonance thing. About the stretch, I searched and the original post is gone.There's still abunch there if you search this forum under stretch. I wouldn't suggest it with a stock head (The quick head is a direct drop in), but basically you get a JR Venture tailboom and cut it to 22 1/8 inch. The diameter is the same, and be sure to cut the correct end (Must leave the end to match the tail mount). Get an ECO 16 belt and 470 blades (MS blades require that spacers be made for the grips to fit. You must also extend the tail control rod. I used a carbon rod. The stretch will make your VE more stable in a hover (Larger disc) and at the same time more responsive. Not sure how that's possible, but it does. Be careful in selecting those Hacker motors. I don't know what the KV rating is on them. The outrunners have a lower KV and you won't have enough hreadspeed with the VEs two stage gear set-up. The C40 8l is still available from FXAero I believe. It seems odd that a lot of manufacturers are now rushing to get a ship quite close to the VE and VE stretch size. With the cost of a new head and motor and Lipos and stretch for the VE you might want to fly as is and get some experience then decide which way to go. I love my VE, but be aware that one of the reasons I stayed with the older design was how much I had invested in it. Once you plunk down $ 170.00 or so for the Hacker, and $ 200.00 for the Lipos there isn't much else you can do with them other than the VE (just an observation. Sorry this is so long, I don't post all that often. Keep us informed on your progress.

Hey DWOEL,
Thanks so much for the info. I will post a few pics of mine tonight as I think you will see why I want to get her right. You are right to suggest to keep it the same for now. I will fly it the way it is for now, but will probably just upgrade the motor to the C40.
By the way I fly hotliners and other toys with a buddy in or near Chatham on an old farm every now and then on Sundays, but I see your way down by the shore.

Be as wordy as you like, I really appreciate all the description. I will look at the stretch but should probably fly her first and maybe break the blades thata I have before buying new ones.

Thanks Again,
Myles

Mylehigh....Glad to see you are on your way. I haven't kept up with the new Hacker designations but like I said, I have the C40-8l. That motor with a 16 tooth pinion and 3s lipos and Phoenix 45 is a good set-up. I still have some old stock parts if you get in trouble. If you PM me an address, I'll send you a set of stock wooden blades that are balanced. You can have em for free. They just decorate my shop wall anyway. Hah!!! Another tip is to be careful with the tail blades as they get chewed up easily on the ground and in tough grass. It's wise to have a set or two extra. Be sure your links on the head are not sloppy. If they are, you could have trouble tracking the main blades. Do you have the manual for your VE? Comes in handy for ordering those parts you need from Horizon. By the way, I also fly sailpanes both electric and pure. Have an Omega e 1.8 that will go almost straight up until gone from site. More of a warmliner but tons of fun.
