Default Any 3DHS 49" Sukhoi Owners Out There?

Just picked up one from Ben at 3DHS - it was a display model he had left over in his shop already built, and I got it for a steal.

Just looking to see if there are any other owners out there, tips, tricks, etc.

Thanks!

GRU

It's the Shell Oil scheme: that tells you how long it has lived in the box!

trying to figure out HOW IN THE WORLD you can have such a great plane in a box for so long. I have bought 5 3dhs planes and had to tear them open the day I got them

Yeah I'll snap a few shots this afternoon - I still have to build a battery tray and mount the cowl, but I'm off today so hopefully I'll get it done so I can maiden it on Friday or Saturday. (woot)

It is a beautiful plane, man. I can't wait to get it up to air it out!

Red face Sukhoi Blues

Well, I took it out yesterday for a maiden - things did not go as well as they should have.

I got it up and it was acting VERY tail-heavy even though I set the CG to be slightly nose-heavy at 10cm.

It had plenty of power, but as I brought it down to the ground for an emergency landing, it stalled sharply and the wheel pants cause on the grass and snapped out the rather flimsy bit where the gear mounts. The wheel pant also punched a hole in the covering on the bottom of the wing.

It was not cool. Worst part is I checked and double checked everything - tightened all the screws, set the control surface deflection to EXACTLY what is recommended.... Oh well, live and learn. I shall repair this damage and soldier on.

Viva la Guerre! She will fly again!

Really sorry to hear about your misfortune.

And am sure you will fix her up, better than before, then have a smooth flight.

Dump the wheel pants and wrap the gear legs with thread (I use spectra 15 lb test fishing line) secured with flex CA.
Balance is critical with these planes, make a balance stand and take your time to get it right. I used modeling clay pressed into the back of the cowl nose ring.
Check your elevator throw with a guage, the plane will snap with around 30-35 degree throw depending on finished weight. Your low rate throw should be 25 degree max. High (3D) rate must be 40 degreee min. Use your radio's expo settings. Mine are -12 on low -45 on high (Futaba)
Also check lateral balance as a heavy wing will make the snap deeper.
Keep some throttle on during landing it's not a glow motor so pulling the stick all the way down kills all power.
Good luck on the re-maiden.
