Flight Trimming - Dime Scale Hemiptere (In Progress!)

First trim session of a dime scale Hemiptere from initial test glides, designed by Al Backstrom and built as a prototype for the short kit available at Volare Products. Kit and build notes are available at this link:

Powered by 2 loops of 3/32" FAI Tan Super Sport rubber with a 7" diameter Peck-Polymers propeller. Next time out with this model I will remove some washout from the left wing and install a Gizmo Geezer adjustable nose button for better precision in thrust adjustments.

I'm still watching the video and thank you very much for helping on how to trim these little planes

[@afxtjet]

Thanks for the vdo. I love flight trimming vdo's. Also thanks for showing the installation of a gurney flap and showing its effect. It will definitely up my game!

[@thomasmccracken9532]

Beautiful airplane buddy thank you so much

[@Colin399]

Nice bit of trimming 👍

[@truebalsamodeller5382]

Great work Sandfac, clearly upping your game - well done!

[@sandfac3427]

Thank you! I'll get this one flying better soon and more videos are in the works. Hope you are able to get out flying this season.

Penerbangan yang mulus dan model yang menarik....saya suka.

[@sandfac3427]

terima kasih!!

[@maciejjjj1]

beautiful flight and model

[@thomasmccracken9532]

I'm concentrate so hard on making my wings perfect I didn't realize how easy it is to fix it with just a little piece of balsa wood glued to the wing here and there

[@thomasmccracken9532]

Down and right thrust seems to be very important once you get your plane going

[@stevenhugh1785]

Thanks for your reply and insight, of course you know what will happen when it's flying perfectly, thermals!

[@PATZAWA]

Very Cool and informative trim session. Thanks for sharing !

[@aidanwelly]

Wow.. Karya anda sungguh mengagumkan..

[@sandfac3427]

Terima kasih. saya masih perlu memikirkan yang satu ini

[@jonathannunez2702]

Great little trim session and narration! Impressive how the plane seems to just hang on the prop and mush instead of stall, thinking it’s related to the tandem wings and washout. Pierre Mauboussin knew what he was doing!

[@sandfac3427]

Thanks! Maybe one day we’ll do a dimer MB mass launch.

Interesting trim session. Thanks for posting. When the wind finally subsides next week in Central Europe, I can finally try out the effects of the Gurney Flaps.

[@qiangqiangpan2362]

The small turning radius may have some relationship with the length of the fuselage

[@sandfac3427]

I think so too. The models I’ve built with longer fuse have larger turning radius

[@stevenhugh1785]

Why did you move the C.G back ? Not a criticism but I wondered what the thinking was behind it.

[@sandfac3427]

I think it was to improve the glide, since the model went slightly nose-down after power ran out on the flight before. Not sure if it was the right thing to do - next time I fly I will start with test glides again and try to adjust thrust more for trim

Did you braid the motor?

[@sandfac3427]

Yes! It is 30" of 3/16" rubber, forwarded braided with about 140 turns in each strand.
