e-JR Voyager E > voyager E - advice

This is my first heli (Voyager E) . As you all probably know it comes with the 540 sport motor and speed controller. I want to get advice on getting it ready to fly. What do you recommend as far as :
1. battery packs
2. Gyro
3. Stay with sport motor or upgrade to brushless if so which one?
4. Servos
5. Receiver and transmitter
(I want to go with a JR radio and considering the XP 6102 vs the XP8103 - I do want something that I can use later as I get further into the hobby, is this too much radio for now)

Am I forgetting anything?
I would appreciate any help

For now

I would stick with the stock motror and ESC until you decide what you plan to do with the Heli.

Don't waste your time with the 7-cell packs that JR recommends. I'm using the 8-Cell 3300 NIMH packs and am getting 8 minutes or so. If you end up switching to a brushless setup later, you will still be able to use these packs. I'm happy with the stock setup, although, I'm not flying the VE aerobatically.

I have a GY401/9253 - Some would say it's overkill, but I disagree - It works very well with this heli - Just be sure that you don't mount it where the book suggests - I got lots of drift and twitching until I relocated it to the front. Tail response is extremely crisp and accurate.

For servos, I used Hitec Mini Metal Gear digitals- Very fast response, and very light too.

If you plan to stick with the stock setup, set the throttle and pitch according to the JR manual - Since you are planning to go with a JR radio, this will be a breeze since the Voyager manual outlines programming steps for both the 662 and 8103.

I would recommend the 8103 (I'm biased) for your TX, and would think that a slimline R700 RX would be the way to go here.

Good luck.

I general, I agree with Greg. There are a couple of areas that I disagree with a little bit though (just a little nothing major at all).

First, while I agree totally with the Gyro (and his warning about location..mine is mounted aft of the main mast on top of the frame), I would give serious consideration to a much lighter servo. I use, and I know a very large group of VE flyers use the Hitec HS 81 on the tail(MG or nylon gear...your choice). These are light weight and reasonably fast (.11 sec @ 4.8v). I've not tried the Digitals, so they may be good all the way around (again, I use Hitecs on the swash...this time the HS 85's). The VE tends to be tail heavy in stock trim so anything you can do limit the weight aft will be an improvement.

For batt's, Greg is right...go with 8 cells and I would also use the 3300 NiMH's. As he said, they'll work for the forseeable future and are a good starting point with a brushless.

On the pitch and throttle curves...for pitch, go with the manual. For throttle, use a curve that puts the motor at the high end of it's rpm range for all your flying. For example, I use 0-20-90-90-100 in Normal and a straight 90% on all points in Idle-Up 1 & 2. The normal mode is used to spool up the blades and I fly using Idle-Up 1 or 2 (depending on type of flying). The higher value will allow the motor to operate at it's most efficient levels, giving the most flight time for a given battery type.

As for TX and RX, take a look at the new 6102 from JR. This is the follow-up to the 662. It has 5 point curves and some additional features the 662 didn't. The 8103 is great (again it's what I use) and if you don't mind the extra bucks, it will serve you well for a LONG time. For the RX, the R700 is in both my helis and in my one plank.

One other consideration. When I bought my VE, I picked up a set of Carbon frames right from the start. Not for the "cool" value, but for the weight savings and strength. I still use them today and they have been through some serious crunches . The Hitec servos fit right in and the weight savings will pay off with increased flight time.

The heli WILL fly on the stock motor if you keep it light and use 8 cells. Once you've worn a few sets of brushes, then start looking at the brushless option.

Thanks for the advice. Things are starting to make more sense now.
Just a couple of follow questions.
As far as the radio goes I noticed that the 8103 comes in a various forms including FM and PCM. Which way to go ?
(XP8103 DT FM Heli MD2 with 537 servos or XP8103 DT PCM heli MD2 with 811 servos)
Also would I not be able to use the servos including in these systems , i believe the 537 is a standard servo and the 811 is digital?
Would the HS 81 and Hs 85 servos be much better and lighter? If so, can you give me anymore info as to the complete model and name as I search for them online?

It sounds like the GY 401 Gyro is the way to go. Are there any close seconds?
Any recommendations for chargers?

Once again, Thanks for the help

Hi,

I absolutely agree with the gyro recommendations (Futaba 401) ... Do mount it on the frame top aft of the mainshaft/swashplate ... Works great there... I'm using mine with a standard servo ... If you go that route be sure to turn "DS" to OFF!

For a charger I use the FMA SuperNova 250S with my 8 cell 3300mAH Cermark NIMH batteries. I ordered it from Hobby-Lobby.com. Easily programmable and works great.

Cheers ... Dean

8103 options

Couple things to consider -

There are great package deals on the 8103 flight packs that include different servo sets, etc. They are really only worth the money if you plan to use the servos that come in the deal. I've had pretty good experiences with the DS811's, They are a fairly decent value. The 537's are relatively slow, and I've never been happy with them for a heli application, but many RR users have had favorable things to say, particularly about their longevity.

At the minimum, you will want the Heli version of the 8103 with digital trims (DT). The modulation is actually selectable via software in the radio (PPM or SPCM, ZPCM), so there is no differences in the transmitter in this regard. If you buy the PPM(FM) flightpack, you will get a RX that is PPM (R700) and with the PCM flightpack, I assume that you will get a PCM receiver. Either way, you will be left with 2 extra servos as the Voyager E does not require a throttle servo (obviously), and you will want to get a dedicated high-speed digital for your gyro (Futaba 9253) I believe that Heliproz has an 8103 package that is configured with a 401/9253 and 4 DS811's.

The choice is yours - If you decide that you want to use the servos included in the radio package, go for it - Otherwise buy the TX and servos seperately.

There are MANY other options that you could consider for your Gyro (GY240 perhaps), but I strongly feel that the 401/9253 combo is the most bang for the buck that I've seen.

On the TX, Greg is right the PPM (sometimes listed as FM) comes with the R700 slimline RX (which is great on the VE). I believe the PCM version may now come with the R770 which is the PCM version of the R700. In any case check with whoever you buy from and verify, because I'm going from memory here (often fails ).

Regarding the Hitec servos, they are much lighter than either the DS811 (PCM Pkg) or the 537 (PPM Pkg). I get mine from Servo City. They consistantly have the best pricing on Hitec's I've found. The models I used where the HS85BB (3 for the swashplate) and the HS81 (1 for the tailrotor). The primary reason I went that route was weight saving since the total weight of the 4 Hitec is approx 2.9 oz vs 6.3 oz for the other combos. If you decide to go the Hitec route, one thing to note...they won't fit the standard opening as they are too small. Two ways to fix that...1) use carbon frames or 2) make a set of adapters. All the carbon frames I've seen for the VE came pre-cut for the smaller servos, so the Hitecs drop right in (and the carbons save additional weight while adding strength).

The other servo option that is very popular for the VE is the GY240. It's basically the little brother to the 401, without remote selection of HH/Rate modes. Good holding power and easy to use.

On the charger, you might want to think long term. If you think you might use LiPO technology at some point, make sure you get a charger capable of properly charging LiPO cells. I've tried a couple and found that the Schulze 6-330d is excellent. Another possiblity would be the Orbit chargers. Astro makes a nice charger but the 109 is limited to ONLY lithium and the others don't do lithiums.

Just my two cents worth (again . )
