I have never flown one of these but it looks like the Ventus should be a pretty good thermal soaring or slope soaring glider? What do you guys think? If it is, you might wnat to join in the fun in April as we are going to see which foam e-gliders are the best at thermal and slope soaring.

We have an all foam e-glider duration contest running in the electric sailplane forum to see which is the top foam e-glider for thermal and slope soaring. This is a contests being run exclusively on RC Groups in the electric sailplane forum.
https://www.rcgroups.com/forums/show....php?t=1413289

If you are good at thermal or slope soaring your Ventus then show us how good it is. Don't let the Radian and Easy Glider pilots have all the fun. And don't forget bragging rights!

Did manage to fly today and the live hinges are the way to go
On the second flight the 25amp ESC packed it in motor draws 17amps and the ESC was very hot ,may have to open up some breathing holes
conditions would have been good except for a few gusts to ~12mph.

I just got in the ventus RXR today. I think I have been ripped off. The wings are flimsy as hell, after rough fitting the plane I can see the CG is way nose heavy, the retract doesn't lock up or down and to top it all off there are no instructions where is the CG?

I guess I will have to start hacking at it, sure hope it will fly :-)

All the things you complain of have already been commented on in this thread. So if you had read all of the thread then you would have been warned about what to expect.

Youtube video is uploading, will post url later. Not the best quality, first video of my assistant, always trying to find the plane and the zoom button.
ok?

Wow did I offend you? I love people like you. You sure make people in this hobby feel welcome. I have a great idea if you don't have anything constructive to say don't speak.

I have been looking at the retracting wheel on the Ventus to see if any modification could be made to take the load off the retract servo on landing.

After a while I came to the conclusion that if the retract was mounted 180 degrees around then the landing load would be taken by the down stop.

Here is what I have done to my Ventus.

1 Remove the retract and retract box from the mounting plate.

2 Cut a new slot for tthe operating lever.

3 Rotate box 180 degrees and replace. Re-glue in place.

4 Cut a new slot for the mounting plate in the fuselage sides.

I now have a retrating wheel assembly that does not put loads on the retrct servo when landing.

Interesting approach, I like your mod. I wonder if somehow a strong enough spring could be incorporated into the landing gear with provisions for the servo and to also act as suspension? Of course swapping it 180 deg wouldn't work for this.

I plan to use a Dubro Servo Overide to allow the servo to not be loaded when the wheel is down. I have one that I purchased several years ago but they are listed in the latest Dubro catalogue under Cat No 120 in the car and truck section.

Could someone please make with pins and cotton a centre line down the fuselage side and measure up to the centre of the leading and trailing edges of the wing and tailplane, as my tail boom was cracked and repairedI am getting strange numbers like wing +4.5deg' and tailplane +2deg' the tailplane Im sure should be negative or at least level with the centre line.

Don't remember reading a previous post about this. Where on the tail boom did it crack and how did it happen? Is this an inherent weak point on the tail boom? And it cracked even with the carbon fibre mods you made to the boom?

I just ordered a ventus from HK a couple of days ago, and will have to consider whether there is an inherent weak point in the boom when I start building.

The tail skid puts pressure on the area under the front edge of the taifin, you can afford to put a decent size c/f (1/2'')tube right down to the end and the extra weight will work in your favour when getting the cg right.
I use canopy glue for all the jobs just perforate the skin it will hold like heck and you can use water to clean up while fresh.

I was thinking that it might be easier to use a servo saver like this:
