Tailplane is now assembled with servos and linkages,
installed a 25amp esc and a 800 3sp as far back as the rudder servo will allow,I fitted a spare folder prop to check how the cg is going , not good about a 1/2'' forward of the carbon wing spar with no RX fitted

If you are building one I would advise to cut a new offset top deck for the wheel assembly with provisions for the servos to be mounted at the rear with the front of the deck shortened ,this would give more room for battery placement.
the hatch attachment is useless as the battery is in the way.
Of course its probably fine as a pure glider.

I got mine a couple of days ago and came with the prop, I am leaving the retract out all together, with 300sq inches I want to save all the weight I can, I may skip the wheel also. Did you notice how stiff ailerons and flaps are, the foam is way too thick in the hinge line and will need serious sanding. I am also afraid I will break those tips a lot, so thin! I am glad it was not that expensive, more like a novelty, I am not holding much hope for the tiny chord for any serious thermaling but may be fun on a slope with moderate to low winds, I expect fairly fast glide, but it looks cool.

I gather you are building it as a glider not power assist?
I also thought about the tips ,one could tape the bottom and the top tip surfaces which may help .

My cartons were damaged and I know from experience that if I want to claim that my prop was missing it is required that a series of photo's be taken and sent ,
here is an example of what they want when a part was missing.

Do you mean the item TR35-42-Shaft was missing from your order 2002036755 and you only received 1x TR35-42B-1250 in the parcel ?
Please kindly help to send us below picture so that we can open claim for you .


1: the pictures of all items and all packaged materials .


2: the picture that show the a kitchen scale for entire parcel

3: picture of the postage slip

Who keeps packaging ?

I will leave the tips alone for now and hope for the best.
No, I am building it power assist, but I like to climb and then glide, I do not fly any of my gliders as power planes. I also slope them with motors, I hate walking down the hill to get them.

I would not sweat it over the prop, nothing amazing there, wrong size for my planned motor anyway. I am considering one of my ducted fans on top, instead of prop for the jet assist look. This glider is just for fun anyway.

i think i will put some package tape for the tips because they are to fragile for my taste

Afew more pix ,I used transfer tape to hold the servo covers on.
you can see why I suggest making a new servo tray.

Went the hack on the battery tray ,removed it and the retract servo and cut back the retract tray,glued in a balsa floor direct to the foam, now the battery goes back further and cg is close.

Keep up the good work, you are saving me a lot of thinking power ,
I see about the battery tray, I am taking out the entire wheel mechanism so I will have more space to shuffle the battery to get proper cg. Huge space in that fuse! Any guess on the cg? I think I will start at 1/3 (33%) of the wing chord, 30% may be safer but I do not like nose heavy planes and most gliders, I am further back then that. The stab is small but so is the wing area and I do not think the last 10" of the wing is really contributing in any way to the lift on this plane. My build is going slow to non, since I have 3 other gliders to finish with a little higher importance then this one, at least in my mind

Dan we think alike on the tailplane area I think cg adjustment is going to be critical ,tho' I'd much rather have slightly forward for first flights.

When trial fitting the wings I noticed they are a very tight fit and I experienced some difficulty in getting the allum ends to line up with the locking collar, to overcome this I found a length of carbon tube that fits up the centre of the allum wing tubes and now use this as a guide.
I cut the servo wires and solder extension leads then coat with 2 coats of nail polish.
I had to cut a couple of mm out of the servo pockets so the pushrods line up perfect,I use gorilla fast cure to glue them in.

It looks as tho' I will tie the retract up for now as I had to remove its servo to get the cg right , I use rectangular magnet for the hatch ,the shape is better than round for carving into foam and added a foam block to the front edge to lock it in, I use gorilla fast cure and a touch of moisture to help the cure and a piece of nylon bag to stop pieces sticking together. Perhaps others might think to use a heavier servo at the tail end,it would have been better if both elevator and rudder servos were down there imho.

I have just purchased a Ventus that I plan to build as a glider, without a motor, to use for slope soaring. Could you please post a photo of the glider version nose cone.

Hi ken ,the nose cone is a simple vacumn formed white .018" wall thickness ABS cone that needs to have a skirt cut off, next series of pictures Ill slip it in.
