Hello all,

Just finishing up a vel 90 build and found that my main blade bolts have way too short of shoulder area! This is definately not the normal for a high powered 90.

I replaced them with trex 700 blade bolts, they have a long shoulder that contacts the entire metal blade grip.

Align bolt on the left, Outrage on the right.

I'm finishing up a BeastX install, when finished I will comment on the areas of the kit that I made changes in.

I did the same and also changed the tail blade bolts to Align as the supplied Outrage bolt had a 70% threaded area which just eats into your blades...

Devens, the revised kit in this case wouldn't matter, Brian is talking about the 3x18mm bolt used to secure the tail blade.

Brian, I saw that as well and have been keeping an eye on it in both of ours, so far in 6 months with 70+ flights it hasn't been a problem, the bolts are hardened.

Velocity 90 build notes:
No, this FBL kit was from first batch. HD sent me new main gear, tail shaft,main shaft, tail rod guides, lower swashplate,...and a torque tube(it was drilled 4 times on one end).

Overall the fit and finish on metal parts was very nice, and there were some great design ideas, like pins included to align all the bellcranks, made for a super easy set up. Also I really liked how the tail rotor transmission is attached to boom, also pitch slider assy. is improved from vel 50. The rotor head is the largest, with axle support that I have ever seen. Super nice fitting cooling shroud, awesome landing gear struts,super large clutch with good pinion support,nice carbon frames-perfect alignment of holes, very nice muffler included, huge plastic links.

These were a few areas I had to address; hopefully Outrage will correct items quickly.

1) plastic cooling fan holes were slightly misaligned.
2) rotor head button head screw too long, cut 2mm off it.
3) clutch hub somewhat a looser fit on crankshaft, I was able to tighten it, but I think it should have a tighter initial fit.
4) engine mount inner edges super sharp, just sanded.
5) tail rod guide screws-heads strip easy, replaced with small phillips screws.
6) **tail boom supports need angled aluminum ends, else you will stress the attach bolts, breaking them in flight(saw it) I just used a file to add the proper angles so supports fit nicely front and back.
7) horizontal engine mount slots in carbon frames need to be slightly longer, to get the best gear fit.
8) tail bevel gears are very rough, I think they should be remolded for a better fit, others say they will break in(saw video of Lucas Riva in Orlando-tail gear failure) he does fly super aggressive.
9) supplied carbon tail blades, too wide-had to sand down in order to fit blade holders.
10) ball links, super tight fit. I installed balls into dremel, used 320 paper and oil to polish them. They are solid steel balls, so this is easy to do.
11)** main blade bolts need longer shoulders.
12) plastic links are super tight on rods. I used a 2.5mm screw to help tap them, heated and oiled them when installing on rods.

Outrage released this kit too early, but they are making changes. There's a V2 kit in Europe already.

I'll included some more pics when finished!

FOXDEN Razz is talking about the main blades AND the tail blades. I would hope the newer kits would have corrected the bolts. FYI With a helicopter every small detail matters.

Humm I didn't get a main shaft or rudder control rod guides.

Thanks for the info Razz!

rip off britain and no changing it

My Posts: All  Forum  Topic

there is no V2 kit. it is only 2nd batch with the updated parts (lower swash, tail spindle and main gear) which everyone can get FOC.

the only other difference is the went with some orange anodising on the clutch bell and engine mount.

hope that clears that up so people don't ask their LHS's for aV2 vel 90 because they will spend a while looking in the book for it.

cheers

Your welcome,

I asked for the new tail rotor pushrod guides, as I read that a few had trouble with them breaking. The new ones have much thicker plastic standoffs.

My main shaft had holes were drilled too large for the auto gear attach bolt. The new shaft I received still had 4 holes drilled into the bottom, one set was slightly smaller than the other, with a much better fit for the bolt. The package part# was R90N033-2.

Thanks for the V2 kit info.

Maiden flight!
Well the WX in Louisville was 53f. today, so I decided to make a maiden flight, for the Velocity 90. I built this heli for a friend, and it has the following equipment:

Align 610's for cyclic, 8900G tail, Duralite 6v regulator-4000 ma Li-ion(will be going to 5200 Fromeco), OSHZ91, Outrage 90 muffler, BeastX FBL V2, Fut GV1, Futaba T10CHG, Radix 710 FBL, stock 105 carbon tail blades. Bellcranks set at 30mm spacing, servo wheels set at 12.5mm, tail servo wheel at 15mm, main blade balls at furthest position outward, normal pitch +- 10.5, idle 1+- 11, idle 2 +- 12, head damper 'gray medium'.

BeastX cyclic rates controlled through transmitter, elv and ail. ATV 85% to start, tail gain 45% with heading lock gain set 'high'.

Just running a head speed of 1750 for hover, 1830 idle 1, 1920 idle 2.

I was very impressed on how smooth and lock-in the heli felt, with these long 710 FBL blades the heli tracked extremely well, felt super solid in hover and forward flight, collective smooth but punchy! With the ATV settings at 85, the roll and pitch are very smooth and intermediate in speed, very predictable, even with 1830 HS. I was most impressed by the tail feel and authority, crisp stops, just solid response. All this right off the work bench with no extra tuning. This tail responds better than my Furion 6 with Vbar 5.0Pro(I'll have to go back and play with the tail settings).

Overall this heli tracks and responds well, very confidence inspiring.

Issues I do have:

1) main gear noisy, getting too much main gear plastic, even after 3 flights. I have too much backlash for sure. Will have to slot carbon frames so I can move engine closer to pinion and see how this works. I may have to 'slightly grease the main gear' we'll see.

2) main shaft has up and down play. I'm not able to remove it with bottom bearing block-it holds the auto gear spacer tight, but the main shaft is moving up and down 1.5mm through the bolt hole in main shaft I believe. May have to add a main shaft collar to top bearing block.

That's it for now!

Brian,

Does your current main shaft have 2 holes drilled in the lower end of the shaft? one hole was the stock and drilled a bit too big and the temp fix was a new hole drilled 90 degrees at the same point but with a much tighter tolerance, I ordered a spare pack and they showed up this week from HD and had the 2nd hole drilled, I used a spare Jesus bolt and the hole tolerance is much tighter, I think this is what you are seeing with the up and down play.

Yes, my main shaft has 4 holes drilled into the bottom...I understand why there is 4 holes now. One set was tighter, I thought I used these tighter holes, but with the play I have, I may have choosen the larger holes....I will check on it. If I remember correctly, the tighter holes were still a bit shaped strangely, longer from top to bottom than the width...not sure why this occurred. If the hole was correct in size, I would not have this up and down play.

Why am I getting all this main gear wear?

The gears are aligned perfectly, but I do have too much backlash, this may be causing the gear wear. I'm going to lengthen the horizontal slots in the frames 2 mm, so I can get a better gear mesh. Then I will see how the gear wear is.

Hopefully the new frames have longer slots cut. My engine mount is pushed rearward as far as it can go, and there still is a slight gap between the carbon frame edge and aluminum engine mount surface. I read that the new kits with orange aluminum eng. mounts and clutch bell were able to close this gap completely. This would make the gear backlash perfect.

I had to slot the frames on my 90 also. It is pretty easy to do and will get rid of the backlash problem. I also flipped the top bearing block and added a split collar underneath to get zero play in my main shaft. This was initially down because of the issue with the holes being too large but after I purchased the updated main shaft I decided to keep using the collar to better utilize the top bearing block to take some of the load off of the bottom two. Plus I do not have to worry about the hole in the autohub eventually being egged out and developing more play in the future.

good idea! I have heard of guys using a top collar but didn't know the flip the bearing block over trick.

Ts8103 thanks, that's a great idea. Who makes a good 12mm split collar?

The ENV 90 and the vibe both have 12mm collars. They were out of stock when I needed them so I had a friend make me some. I do believe that they are back in stock at Helidirect of Heliproz.
