Well I was wondering what those who have gotten and installed the BH upgrade are thinking about the new blade CP? I installed mine lastnight and I'm gonna have to probably put the flybar weights back on to keep it a little steadier in a hover. Talk about responsive. I just wanted to know what more skilled pilots are saying because I can see deffinite advantages in 3D but it makes hoverin a bit trickier.

I flew mine to night and im going to have to detune it a bit.I run 2600 plus head speed and it's a hand full,I will prob put the weights back on and maybe a little D/R and slower head speed untill I get used to it.

I tried mine yesterday. It sure seems a lot quicker but I had a wicked wobble problem so I was not able to get a good read on it. I am hoping the wobble was from having the blades too tight but this snowstorm we are having is keeping me from checking it out after I loosened them up. I guess I'll have to wait till later and keep my fingers crossed.

At first mine was very unstable and very sensitive to cyclic inputs.Also the cyclic trim settings seemed to off a little. I had installed all 4 of the dampner washer ( 2 on each side . I have removed 1 washer from each side and it is now more controllable. The cyclics are still fast and it has a good feel now.The trim setting are also back to near neutral as well. Be ready to use less cyclic inputs with this setup. After this I installed a set of carbon blades and I really like the way it flies now. Currently I am using the stock battery and stock motor and the flight times have come down to about 5 minutes before the battery looses power enough to lower the head speed. I will be getting the AEK and lipo's next to get the longer flight times back. For those wondering I would not recommend BH upgrade for a beginner. To fast control equals slower leaning curve with no doubt more crashes. Chuck

That is incredibly odd that your flight time changed because of the B/H upgrade. It should not effect that at all.

cwright flight times dropped because I think he went from flats to CF blades and if still using the stock motor the head speed would kill the flight time with the 9V PACK.

I flew mine outdoors this weekend with the BH head,after a few circuits took the F/B weights off and set the head speed at 2450
(tacked) at hover,what a kick!!Watch the FF turns it will roll fast. almost full rudder(DDTail)to get the back to follow the front on the exit

rand1960 you are right my flight times went down because I went to the carbon blades from flat bottom blades. I have on order a TP 1200 pack that will be here on Wednesday. I will be picking the AEK also at that time to get the flight times back up. Chuck

Looking forward to this upgrade but LHS still didnt have it in stock. I needed a spindle bad and he was out of that too. So next week Horizon Hobby online will grace me with a box-o-goodies so I can play too.

Really wanted to get a futaba 7channel but that will have to wait just a tad longer since I spent my allowance split between teh LHS and online <g>

Watchthe electronics for sale sometimes the 7CHP is listed for $100.

Good Luck

I just got done flying off a pack on the upgrade and while I've not yet had the chance to do any acrobatics with it (snow on the ground... Cold... Windy...) I was able to hover it in the house and get a good feel for it.

First impressions of the upgrade kit...
It's very nice. I really like the fact that everything is together and comes with 6 ball bearings, 4 shims, 2 blade grips fully put together, and the spindle. The only thing that was missing that I thought was kinda odd was the hex nuts that the screw goes into that holds the blades on. Other than that it's very nicely put together.

Installation was easy. Just remove the old one and it litterally pops on in a matter of minutes.

Here's where the quality of the components comes in. With the old 2bb grips that I had on it with my woodies. Once I had them both set to 0 degrees at mid stick in idle 1 I would have to add about 1 full turn of pitch on one of the blades to get them to track. Not this time. I set both to 0 pitch with the new setup and then spooled it up to track. It tracks perfectly with both blades at 0 degrees in idle up pretty much through the whole gamut of stick movement. I was litterally shocked.

So how does it fly. Wow I am glad I didn't have this on the heli when I was learning. I would never have been able to hold a stable hover. I had to add in about -65% expo on the aileron and elevator to get the heli to respond as it did before the upgrade. The slightest stick movements without the expo just jerk it around. It's very precise. I can't wait to take it out to the field and turn off the expo and yank it around. This thing will be rockin. For indoor hovering though I STRONGLY recommend (if you have a computer radio) that you tune it to around -60% to -65% expo.

I'm jazzed. A lot of the slop went away that I had in the head as well but the flybar slop still remains. I really need to replace the rotor head and center hub to get rid of that slop. It's in the mounts for the bearings in the rotor head. Those things wear out SO quickly.

Overall for those that are ready to move into acrobatics I give this upgrade a 10 out of 10. Amazing. Not for newbies...

herm...
after reading L0stS0ul's last post seems I should have saved my money for a computer radio first. Ah well, I have the upgrade ordered and the extra B/H grips and I will wait to install until I either break the non B/H grips or update th'radio

now, if I wasnt so confused about freqs,, I would really like to get a channel unused by local flyers but the only way to swap channels is a 9c - then again thats in another thread <g>

tinner ,if you're worried just double up the flybar weights

Setup is everything, All my heli's can fly far better than I can pilot them

Also I have read here of guys saying how touchy the Blade is to fly. After the first flight I pulled off the the weights completely and still think it's a dog in the cyclic area.
It's all relative to a persons experience with heli's. I'm personally used to a Raptor 50 with the fastest/lightest paddles with 15% expo and the the stock Blade isn't that LOL!!!

Good point,

I am really anxious to upgrade to a better radio but I mention it to the wife and her eyes glass over…

One step at a time,, eh? <g> at least I am getting the repair inventory up

wish I would have thought to increase the expo. I just had my first wall contact with the BH upgrade and that tinly little shaft that holds the mixer to the blade grip snaped fery easily. I've got a spare upgrade on its way but its not here so for the night I'm grounded unless I magically produce a Gyro and a new battery for the Revo. I can deffinately say that flybar weights will have to go back on for this mod because for my newbie thumbs its just way too touchy with the BH upgrade.

I set my Blade up with a Airtronics RD 8000 computer radio and frankly wasn't too impressed with my results. It flew fine and all but not much better than my setup with the stock TX once I set it up correctly. From the factory even though they are test flown [and I believe them]. Just cause they fly don't mean they fly really well.
I would use the computer radio if I went to a BL motor etc but we are talking of very finite power here with the Brushed motor.

I set up my heli and posted my setup here http://runryder.com/t224578p1/

The post starts with "well hear goes,," It describes my findings and my final setup.

I figured for 10 bucks for a Futaba Xtal it would be worth a shot. I just went back to the stock TX with my setup and am happy with what it is. Except for the Bell-Hiller upgrade for 25 bucks I'm not doing anymore to it.
It is what it is, a really fun cheap heli that you can fly in your driveway etc. and if setup correctly will perform good.
It is one of my favorites though just the way it is.

For those of use that dont have a computer radio to be able to change the expo's, I would assume you could get almost the same results by moving the linkages in on the servo horns. Just a suggest worth a try.

Yes you could but for most with little to no experience I would suggest adding extra flybar weights instead. The cyclic is poor on the Blade CP as is and most problems of touchy control are because of too much pitch along with too little head speed,which makes it very unstable or,,,twitchy
