Hi guys, so I've got a Trueblood leveler for my Trex 600N, I would like to know if I can use it if I build a JR Vibe 50. If I can't, would someone know of a tool which is just as good? I have a leveler with the bubble guages, but I find them not as acurate as the Trueblood when trying to level out the interactions.

Thanks

Ben

Not "just as good", but BETTER

90 degree angle at the servo linkage from the horn to the bell crank.
and 90 degree angle from the belcrank to the linkage to the swash.

That will get your swash as close and as perfect as it will ever get on the bench. The rest needs to be tested and sorted out at the field.
but I find them not as acurate as the Trueblood when trying to level out the interactions.
Im afraid no "leveler" will help sort out interactions, it will just tell you when your swashplate isnt level.
Instead,
Try holding on to a flybar paddle loosely with just your fingertips while working the cyclic. You'll know it when you feel it. THAT is an indicator of CCPM interaction.

Thanks, but with the Trueblood leveler, I can get a perfectly flat swash setup without all the trail and error at the field, that's why I love'em.

Cheers

who cares about a perfectly flat swash? It only looks good on bench, but doesnt help the helicopter much in the air.

The real test is a climbout both upright and inverted.

I though the closest you could have to a trimmed heli, was a level swash. Yaw the heli at all and the wind may try to make it roll in a different direction - and so can't be trimmed. I also like the idea that you could see tiny interactions on the bench.

I want a swash leveler for a 12m mast.

I don't see how you can rely on a heli tool that uses bubble levels. - You'd have to spend a good bit of time making sure the chassis was level, and then if the skids give at all...

Thank you for your contribution, but no one has yet answered the original question. I agree with Cam, as in my experience it is much better to get the swashplate leveled in all pitch ranges with a reliable tool on the bench, rather then spending tank after tank of fuel and batteries just to get the thing leveled. Could someone who have a Trueblood leveler, and worked with both the Trex 600 and Vibe 50 please just tell me whether the tool works for both.

Thank you

Ben

I don't believe it will work by itself. I have a similar leveler and had to use some bar stock across the swashplate to get the leveler to hit the swashplate because the prongs on the leveler and swashplate just miss aligning with each other.

Cam this will work with all mast sizes.

The 600 leveler works, but not well. It will only touch 2 of the tops on the swash at one time so you have to level 2 of them, then rotate the tool to check the third.

I hope Trueblood makes a dedicated leveler for it eventually

To finally answer the original question:

Can a Trueblood swash leveler tool for Trex 600 be used on a Vibe 50

No, it can't.

1) Two of the "claws" won't sit on the vibe swash arms making it impossible to align anything (just as mentioned by Funky Trex)

2) even if they would align, the leveler doesn't even fit the Vibe 50 mainshaft. The JR mainshaft is 10.02, the align mainshaft is 9.86 and the leveler was made to around 9.95mm so you would need to enlarge the center hole to make the leveler fit the mainshaft (I did and then I discovered issue #1)

3) I already asked at Trueblood for a new swash leveler specific for the Vibe 50 over four months ago. I was told that they would make it... still waiting.

4) Alternatively, I decided to use the dial gauge method which works suprisingly well:

Wow - good idea Tony! ROI on the swash, a bit more complex than the L wrench and zip ties but very accurate.

I did try a Trex-600 swash leveler on my Predator last weekend - it worked but was resting on the ball links rather than the arms of the swash. Worked to get me a lot closer than I was before.

Very precise indeed. Each mark represents a 0.01mm deviation (like 0.0002 inches or something like that). I managed to get everything lined up perfectly without the needle moving

I use the DI method as well, except I use digital. It also helps for making your elevator and aileron inputs symmetrical as well. Pretty much required for 140 CCPM.

will wash your heli for a quarter

i completely disagree with that staement Dood.

for a perfect setup you need these 3 things

1. a perfect balanced heli both directions
2. a level swash with no interactions
3. no trims used at all on ail or elev.

if you take the time to balance the heli you will have a really nice flying heli most people dont take the time to do it.

the minite you use any trims you just wasted your time leveling it in the first place

when i setup my heli i disable all the trims.

do you completely disagree or just partially disagree?
I know you said "completely", but I don't think you mean it.

"the minite you use any trims you just wasted your time leveling it in the first place"

I agree with that. but what I say is, 'when you use trim, you just wasted your time setting up linkage geometry"

You think header tanks "are for pussies"
I think swash tools are a waste of $30.

I don't believe you "completely disagree" with me,
is because I don't disagree with the above..

What I'm saying is that, you don't need a tool to get it there.
There is no substitute to a perfectly set up heli, everything at EXACTLY 90...
