With light RXs (<1g), ESCs (<1g), servos (2.5 – 4g), and smaller 120 mah packs, getting below 100g is relatively easy with most of the modern coax systems that weigh ~15g or less with 13” CF props. The larger 15 and 16” props are lighter, more efficient, but more fragile, and actually are not stressed for thrust loads needed from planes more than maybe 75g.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>If you can find an older Kimmo system (2s, 2 motors, 2 escs, geared), it will have plenty of power for a 100g plane, and likely be fine up to 120g. I did forward your email to someone that might have a Kimmo for sale.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Here is a link for Lantsov coax systems – <o:p></o:p></p><p class=MsoNormal><a href="http://www.pauzuolis-rc.com/product-category/equipment/coaxial-thrust-systems">http://www.pauzuolis-rc.com/product-category/equipment/coaxial-thrust-systems</a><o:p></o:p></p><p class=MsoNormal>AL-16-120 2S with 13” props is a combination I have run (with cautious use at higher power settings) and it has excessive power for a 65g plane.<o:p></o:p></p><p class=MsoNormal>The Pauzuolis website is pretty good with email, and if you want to contact Alexey Lantsov directly, he is responsive on email <a href="mailto:alexeylan@mail.ru">alexeylan@mail.ru</a>, Facebook, and RCG.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><a href="https://www.glavak-rc.de/">https://www.glavak-rc.de/</a><o:p></o:p></p><p class=MsoNormal>SG CRE 04 17 0.40 is one of the original coax systems and will have plenty of power for a 120g plane.<o:p></o:p></p><p class=MsoNormal>Glavak recently posted a new pricelist this month.<o:p></o:p></p><p class=MsoNormal><a href="mailto:glavak@gmx.net">glavak@gmx.net</a> is the email address, and Alex Glavak is also very responsive on Facebook.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>There is a newer coax system from Russia that was used by Dmitri Starostov and it is for 1s or 2s, but I think 100g is pushing the upper limit for it.
