Working on getting everything together for my winter build. Is there any must have upgrades for this kit? Was thinking of getting the aluminum main bearing blocks (not to keen on plastic ones. Also what servos would be good for this heli. Was thinking some high end MKS or Torq but not sure it would be money well spend as I fly only light 3D. Have aligns on my other birds and have had good luck with them but keep reading about slop in servos and I don't want to throw money away either. Thank for any input. Here is what I have so far.
Rave 90 FBL kit
OS 91 Hz-R speed w/ powerboost pipe
Silverline Vbar
Push to glow

This will be my first nitro build.

Also what mains and tail? Thanks

I may be biased, , but I think you are going to love this build and this heli!

No upgrades are required. If you want or prefer the aluminum bearing blocks go for it, but it's not necessary. I have two ENVs, one electric and one nitro, and both still have the plastic bearing blocks and they work well.

I have one with the Torqs and one with Savox HV servos and I like them both. Super high end servos are not necessary, in fact I think you would be happy with any middle of the road digital servos... Align 610s or something similar would be fine. It's whatever you can afford or prefer. I've had a lot of luck with the Savox/Align servos and have yet to be disappointed in their performance. They can be a great value!

Stock tail blades are fine, I also have used the Radix 110mm with good results. Main blades... I have a YS120 in mine, running Radix V2 710s and just love the feel. 690s might give you a wider envelope, and I think that's what most people prefer on the nitros. I like to do autos and I really like the 'float' and the energy of the larger blade. Just personal preference.

I have a Silverline on my electric and it flies really, REALLY, well. I'm not a whiz on Vbars, but if you need any info on settings I can dig that up for you.

Have fun with the build! Kinda wish I had another one on the bench to build now...

The Aluminum bearing blocks are nice, not expensive and are NOT required. What I did notice is that they allowed for a EASIER alignment when tightening down the main frame bolts while testing the main shaft alignment.
When building with the plastic blocks most builders will over tighten the blocks causing an alignment issue.

Servos are more of a personal preference. I had the Align 610 servos and they were ok. I had 2 fail on me that were on the throttle, so vibrations may be an issue when used in that area. Currently I am running the Futaba S3051HV on throttle and it is working very good.
Currently I run the JR8917 on my ENV Nitro and they are great but expensive. I run the Futaba BLS253 on my Ballistic and they are just as good. If your budget is not an issue then go for your choicees mentioned.
As ExFokkerFlyer mentioned the tail blades in the kit are great and I would also reccomend the 710 blades.

If anything comes up in your build reach out here and you will get the help you need.

Your gonna love this heli!! I'm running the Futaba bls HV's, and love them, but I agree with ExFokkerFlyer on servo's.
Any good quality digital servo will work well on this machine.

I also use 710 v2 Radix mains, and 110 Radix tails. They work really good on this heli. I've tried many other brands of blades, and keep putting the Radix mains back on. I just like the feel of them better, and they auto great.

I run the metal bearing blocks. Thats the only upgrade I've done. I heard the plastic ones can get a little play after some hard use, so I opted for the metal ones. Keep in mind that I never even installed the platic ones, so they may work fine.

I run the same engine/pipe combo that you have, and it rocks!!

The build goes quick, and easy.

Enjoy!!!!

Tom:

Thanks for the reply. I was thinking of the Radix 690 or 710 blades for mine. I guess my feeling on servos is that if your not doing smack or any other type of hardcore flying, you won't notice a difference in servos. I may just go for align 615's for cyclic and 650 for tail. They have served me well in the past. I fly mostly inverted and upright circuits and am just learing how to fly backwards inverted. Would love to be able to bang the sticks like some of these guys can but my head just can't keep up with it. LOL Think smooth aerobatics is more my thing. being that you said you had no probs i'll just run the nylon bearing blocks. Got a nice deal on everything for this build so I don't want to go crazy but I do want a nice flying bird. Tom also did you use JB weld to mount the bearing blocks to the frame and possibly the outer race to the inside of the nylon mount?

Thanks again
Dan

All great info guys. Maybe I will just save up to get some better servo's then. I found a few sets for sale on here and HF for a decent deal. I've got all winter so not really in a hurry, would just like to have everything to do the build before I get started on it. Right now its just mains and servos. Already have a throttle servo so i'm good there.

I like having everything sitting in front of me when I start a build too. Just about any decent digital servo will work, but whats really important is that YOU like the servos you put in it. In my case I think the Savox HV servos I have are probably better than the Torqs I have... but for some reason I like the Torqs better. Just feels better to me. So whatever you like, you should go with. It is a hobby right? Supposed to be fun!

I did not use JB Weld for the bearing blocks. There is a trick to use a little piece of paper between the plastic block and the outer race of the bearing to reduce the play. On one ENV I did this and the shaft lined up well... on the electric ENV, I ended up not doing this and the bearings lined up better for that model.

Congrats! You will love the ENV

With this being your first nitro build, feel free to ask if you have any other questions. I run YS, but know several guys running OS on here.
