Trex 500 Build Videos

[Finless]

MK1 this has been discussed before here and in the 500 forum. My kit was a FIRST KIT and thus based on my input and others, Align has changed the manual over what I used in my build!!! However, If you go to post #1 you will see I have made NOTES in RED that state these changes.

Thanks for pointing this out though,
Bob

Hi, OK sorry Master Bob.

Something else I'm noticing, is nothing to do with you, Is that on page 6 top diagram it shows a small capital 'A', which is now present in my manual on the inside of the radius arm.

Naturally 'A' is outside.!!!!!

The washout control arm and radius arm came pre attached and thread locked.

Can you confirm if this is an exception to the 'A' rule.

I trying not to look a fool again!

Hmmm that is screwed up I think... I looked at my page 6 and YES the A is shown on the INSIDE! My elbow arms had NO A on it!
Bottom line look at the elbow link and look at the diameter of the link hole on each side., It should be clear that one side has a larger RIM diameter that the other side. The larger rim goes onto the ball first....

I see we will have changes and possibly a couple rev's in the manual over time. I may have to do a "manual updates" video in the future.

GOOD CATCH MK1.....

Thanks master,


I've just checked with some digital calipers and believe the 'A' side is the widest side measuring 4.46mm. The opposite side measures slightly smaller.
To be honest I don't believe its as noticeable as looking at another type of link such as the ones that go on rods.

I obviously don't want the link to fly off and ruin my investment. Although the manual says 'A' to outside, in this instance and by measurement,although the measurements are nearly identical, i will follow the drawing A inside.

Well like I said my kit did not have an A on either side but if there is an A now then that would be against everything Align has done... So you got me confused...

Bob

[mk1spitfire]

I think you said you had 'B's labeled on yours and they went inside, now 'A's replace 'B's inside. Confusing.

Would be nice with some Align feedback on this.

Better I hope when metal arms appear.

Is it easy to edit parts of your video when you have uploaded?

Head now complete!

looks great the picture on the box but now complete out of the box with canopy on it looks awesome!

Thanks for videosBob

i believe my radius arms have different letters on the inside...one has "A" and the other has "B".

[j bomb]

The arms are probably made in a mold w/ multiple cavities so that more than 1 can be made at a time. Each mold cavity has a different letter so that any quality issues can be traced back to the one that the defective part came from. This is common practice w/ mass produced injection molded parts. The tail blades for the 450 are the same way.

Try this one. I had an A only on one and a B only on the other one. Here's the kicker. The B was on the outside on one and the A was on the outside of the other one. Calipered the id's of each to determine which way they went on.

Mine were both 'B' and went on the inside.

David

mine are exactly opposite: A on inside of one, B on inside of other *shrug*

Finless:

Just wanted to post a quick "thank you" for your videos. I had my new TREX 500 built and flying in one day thanks to your outstanding videos. They have made a world of difference!

Keep up the great work and I appreciate your contribution to this hobby.

Hey guys. I'm working on my build and on video 2 for page 6 making my links that go from the mixer arm balls to the swash. It is indicated in the vid. that we use the 31mm rod with an indside gap of 21mm instead of the 34mm rod with an inside gap of 24mm as indicated on page 6. Which are we using? Thanks..

[Finless]

Because I got a early kit... my manual was WRONG.... Use what it says in your manual and this will get you real close... Follow my setup vids after that...

Bob

[Moreflying]

Thank you for your commitment and help! Your videos make this great for us visual folks. A large part of my success in this hobby is linked to your help on this site. Much appreciated.

I'm not sure if this is the best place to ask, but after installing my blade grips, I feel a lot of resistance when moving them. I put plenty of grease on the thrust bearings. It this normal. I thought they were supposed to turn freely and almost fall around on their own weight. Thanks.

yes...they should turn like they're on...er...bearings.

maybe you didnt get the thrust bearings pressed all the way into the grips?

[highland flyer]

I think you will find the thrust races have not seated properly into there tracks causing them to pre-tension the grips.

Suggest you try slackning a spindle bolt then give the grips a good waggle to see if they will seat properly. If not you may have to dismantle and use the grease to hold the races in position whilst re-assembling.
