Chris,

I'll shoot a picture of the wiring on my X50 tonight. It's totally different than yours, and is not currently using an S.Bus receiver (it will be soon ). Just a different way of doing the install.

Steve

Cool, I'm curious to see how you did it.

I finally made up all the ball links, and used a few extra parts to make up a push/pull link for the throttle. I've programmed the swash and levelled it all out, and all that is left is to program the governor/gyro, pitch and throttle curves. I ended up choosing a Hobbico Life Source (PO4) 2100mah 10C battery, which fit perfectly into the receiver tray. I use a couple of these batteries in a 100cc extra 300, and they work great.

I also added some KBDD tail blades, but the stock blades were just as stiff as the replacements. So the build is complete, and once the programming is done I'll be moving on to breaking in the motor and getting some initial testing completed. Once I've completed the review I will post a link up here for you to follow, and it will also be featured on the home page.

The Life PO4 2100mah Battery.




Push/pull pushrods installed (swash level on the head).






120 degree swash level tool.


The completed heli!

It is a very nice machine, super high quality and very well made! I'm very impressed so far, and can't wait to get it in the air.

Thanks Steve, unfortunately the weather didn't cooperate over the weekend. I'll probably do a little hovering at the house to tune the motor and then take it to the field this weekend for the maiden.

Alright, after a little back and forth setting up the push/pull linkages and some programming on the gyro/governor, I've got everything charged up and ready for tomorrow morning (err...at this point I guess it's later this morning ). I'll report back and let you know how it goes!

Okay, so Saturday didn't go quite according to plan...

Since I've been flying electric for the past couple of years, my nitro starting equipment kinda got neglected. I was using dual nicad packs on my starter (a sullivan dynatron), and after I dug the starter out I discovered that the 8 year old battery packs were totally dead.

So no problem, I'll just use my buddies starter out at the field - right?

Well, we get out to the field and my buddies starter (which was pretty old too), decided that rather than turn over my motor it would rather just burn out some contacts. Three times! We kept taking the starter apart, repairing the damage, and kept trying again. Unfortunately we couldn't get it to run long enough to start anything, so we had to call it quits.

Cut to today, and I'm back from the hobby shop with some fresh batteries. I solder on some new connectors, and now I have a little over 16 volts . In my driveway the Redline .56 started right up, and after a few tweaks on the throttle trim I had it in the air! I couldn't really do too much because, A) it was in my driveway surrounded by neighbors, and B) there was no wind, so I was asphyxiating myself. So I got a quarter tank of gas through and had to call it quits. I took the time to dial in the gyro gain a little, and plan on taking it to the field tomorrow.

In the mean time, here are some pics from the "failure to launch" day....

Great pics...Especially the one of the Raptor 50 with the flames canopy! LOL! Kidding aside really nice close-ups. I hate that I am probably not going to make it to the field during the week to see its official maiden. Interested to see what you'll do with the extended flight times compared to your electrics!

CSpaced it would be gr8 if you could give us the $$$ spent on your build for both the 720 & X50 so we guys can also get an idea of the hit we r gonna take when wife sees the cc invoice. Mostly looking for why did you choose these components & r there any better options. Honestly I get very confused when buying heli goods due to the upgrades available.

I'll have all the details in the upcoming review, but you can pull up most of the info at www.towerhobbies.com. I picked the 701 because I am a long time user and fan of Futaba Gyro's and the GV-1 governor, the 701 was just the next logical step for me as it combines the best of both worlds, plus it integrates extremely well with the 8FG transmitter. As for the servos, again I already use Futaba servos in other helis - plus I really wanted to try brushless!

As for upgrades, no need to worry about them - you don't need any with the X50 .

Thanks for asnwering here in area we get the kit with 4 diff engines tt53 /56 or os 50/55 + two mufflers & not to mention the aluminum & bearing upgrades for the kits I planning to take the plunge but JR Vibe 50NEX is also looking very tempting especialy with the flybarless sytem.

What does he mean by saying "extended flight times compared to electric"? Do you really get more than 10~12 minutes? <G>
