Default Trex 450 Pro build videos

OK.... so many have asked if I was going to do a 450 Pro build and to be honest I had not heard from Align on this heli so I was not sure.... I knew I would eventually go buy one but was not in a rush. Then I got a PM from Helifreak user Helismith who works for Helihobby.com and he asked if I wanted to do a build video on the 450 Pro sponsored by Helihobby... Well heck yea!

Helihobby has come a long way in the last year and is now one of the best online retailers out there! When they asked me I was honored and am glad to be doing this build series for them. Major props Helihobby.com and thanks Helismith for asking man!

UPDATE! 2/1/2011 - Servo Installation warning! You can bind up the servos if you are not careful when mounting them. Especially with the Hitec 65MG or 5065MG.

Video Link ->Servo installation issues and warning (44 Megs)



Anyway on with the show!

Video Link ->What's in the box!! (46 Megs)


Folks.... CHECK your head for grease and Locktite!
Video Link ->Head Build Part 1 - Head, Grips, etc (66 Megs)

Video Link ->Head Build Part 2 - Flybar, links, etc (47 Megs)

Video Link ->Servo Install and Setup Part 1 (76 Megs)

Video Link ->Servo Install and Setup Part 2 (42 Megs)

Video Link ->Tail Assembly Part 1 (50 Megs)

PIN the boom! I was easily able to pull the boom out of the heli with the boom block tight. See it in my video.
Video Link ->Tail Assembly Part 2 (53 Megs)

Video Link ->Main Gear & Shaft Install and Head Setup (82 Megs)

OK on with more vids.

Video Link ->Tail servo install and initial GP750 gyro settings for servo type (40 Megs)

First up is how to setup the tail and GP750 gyro STOCK per the manual.

Video Link ->Setting up the tail and GP750 Gyro stock per the manual (100 Megs)

OK as I said while trying to get the tail setup there was something I just did not like about the tail geometry. We all know it flys STOCK but I think things can be improved especially for guys wanting to setup rate mode flying. So with that I did a bunch of vids to explain what I mean, show other helis tail geometry, and finally my mod with a flying testimonial.

OK so here is a little discussion on tail geometry and why things should be 90/90 etc.
Video Link -> Tail geometry and what it's about and why do I care? (61 Megs)

OK with that basics, what do other helis look like? I went to the field and looked an MANY other helis and will show you.
Video Link -> The proof... what do other helis look like and why is the tail odd with the Pro? (50 Megs)

OK so here is my mod to fix it. You don't have to do this as we all know the heli flys stock but for rate mode flying setup I see NO other way! As far as I can tell it is impossible to setup rate mode without binding. Well I found a solution.
Video Link -> Simple Tail mod! Flip the grips! (70 Megs)

Finally since my heli is not flying yet, Kevin (Fireup) tested the mod this last weekend. Looked good to me!
Video Link -> Fireup testing the mod! (51 Megs)

OK now that all the tail stuff is out of the way, here are the fianl videos!

Video Link -> Electronics Placement (63 Megs)

THE ATD!!!!
Video Link -> First After Market upgrade for the 450 Pro - Fireup's ATD (25 Megs)

Video Link -> My final radio settings before the Maiden Flight (36 Megs)


Video Link -> Flight Review (60 Megs)


Video Link -> REVIEW - KDEDirect's 450 Pro Upgrade kit (11 Megs)

Ok, I'll be patiently waiting for the build videos and especially your flight report and personal views on the Pro vs SE V2.

The build looks pretty straightforward, so this should be an easy one for you.

Thank you Bob and a BIG THANKS to helihobby.com! I'll have to add that to my list of online stores.

yeah I am very interested in the flight test, it looks pretty easy to put together, but the wiring so far has been a nightmare... With all the trex 450 se v2's going on sale, the flight test will be the deciding factor for me. Although after watching Kevin... this thing looks like it can take some serious abuse.

Underneath that piece of yellow plastic is the landing gear, unless your kit didn't come with any.

Naw, Kevin's way better than I am, I was just amazed that the heli took those crashes as well as it did, I've never seen anybody crash like that and just take off again.

We at HeliHobby are the honored ones Finless thank you for the kind words and the really nice plugs. Can't wait to see your videos on this heli I personally don't miss any of them for any heli and I am sure that it is true with all of us here. What you do is amazing and HeliFreak is the best forum on earth. Being able to contribute to that is truly our honor.

We all watched it today we could tell how excited you were. This heli just makes me want a 450 again, well one I wanna fly I mean.. I am definitely going to get me one of these soon.

Glad to see they fixed the torque tube.

Bob,
are you going to do a parts comparison between the SEv2 and the Pro? I saw a torque tube upgrade for the v2 and wondered if parts are going to be compatable enough that I can upgrade my v2 to a v3 or if it's even worth while (performance wise and price wise). I don't really want 2 450's and I really like the SEv2 as is right now . . .

thanks

I wont really be doing much there. There are very few parts that are compatible from what I has seen so far. Main gear set is the same. Boom should be the same from what I have been told. Other than that... NADA.... I also don't have the TT upgrade for the V2 so I cant compare that to the Pro....

Bob

This must be one of the best 450's to date.
At least in the top 3.
Looking forward to the build.
Bob as always keeps me glued.

Does anyone know how far the tail should slide into to the tail holder. I think i'm not set seeding my torque tube far enought. I works but looks like the push rod for the tail servo is a little short now.
