tailboom stretch - What does it really do, does it allow you to run with longer main blades?

What is the purpose of this mod?

I have my VE running very nice with an Eco8 alum aftermarket head and carbon fiber frame and Hacker B40-8L.

What will the tailboom stretch give me?

thanks

Yes, the stretch will let you use longer blade 463mm or 470mm. You will feel the heli more lighter and more respone, not mention about the look of it. It become a new Heli for you.

Vu!

To do the stretch, you will need...

A Venture 30 tailboom (cut down to 22 1/4 inches), an ECO 16 tailbelt,
and blades (blade size can be up to 475mm), a replacement T/R pushrod ( I used a CF rod and linkages...just reverse the servo so that the arm sits between the frames and connect the rod....straight, strong and simple). You might want to consider a set of CF tail fins to lighten up the rear end and help shift the CG forward a bit more.

Very simple to do and the result is a much nicer flying heli.

The ideal combo is a brushless motor (Hacker C40-8L) and a 3s3p LiPO battery of approximately 6000mah.

Libellule,

Tailboom on the stretch is substantially longer than the stock unit. As a result, you need to increase the length of the tail rootr push rod. Some folks have worked up extensions to the stock pushrod, others have made new longer pushrods from wire stock. I chose to go a slightly different route and made a carbon fiber pushrod.

The problem (if you call it a problem) is that the C/F rod isn't going to work with the stock servo location.since there is no flexability in the c/f rod. The fix is easy...just reverse your T/R servo so that the head of the servo is between the frames instead of on the outside. Get a c/f pushrod kit from your favorite supplier and cut it to the apropriate length then attach to the ball on the servo arm and T/R control arm.

This allows the pushrod to run straight down the underside of the tail boom and there is now no issue with the rod binding in any way. I've been flying mine like this for 2 plus years and have had zero problems with it.

Hope that helps,

Ralph W.

thank you Ralphw

I like your idea. How do you fix the link on the c/f pushrod ?
(Not directly on the balls ?)

All retailers sell this carbon fiber pushrod ? Mine not sell it

Did you have a picture from your tail c/f rod ?

Many thanks

The pushrod can be purchased through Rick's RC or HeliProz or almost any online retailer. The set will have a pair of threaded fittings that you glue into each end of the pushrod (I use JB Weld to secure it) and the ball link goes on that then connects to the ball on the servo arm and the t/r control arm.

I don't have any pictures right now as the tail is off mine for maintenance. Sorry.
