hello

cool model, is it Hacker made?

mine is Hacker made, with 1900mm wing span so in Inch it wouls be 74.8~in.

untill now, all my work on the model was on hold as i suffered CRAZY back pain and spinal disk issues...so it is very difficult to work on my models
i feel better now and will continue the work hoping this week by installing the engine->cowl followed ny the rear servos as i want it to be perfectly balanced
so all the rest interior EG fuel tank, radio, Batt ...etc will be after that while making sure the CG is on the spot at all times.
CG is 90mm beyong leading edge of the wing acording to the manual
BUT, you never know till you get it up to the air...

my rule is , to keep it by the book, than make just a bit, nose heavey, go up...and than move the battery Fw<_>Bw to get the perfect CG per the model performances.


i want to use a basic prop 23X10 for my JC60cc engine - that will get me up to 200KMh...
if i will use the racing props EG 19X16 - it will get me up to 250Kmh and each landing would be with engine cut as must, as it wont slow down.

what prop do you use on the G80?
did you convert the G80 to nitro? i know that at the time , modelers use to convert a bog GAS engines such as the Zenoha 80 to Nitro , which produces much more power with less weight , no ignition or magneto...

i'm adding the PDF here so you can get you impressions

happy landings
Gadi
