We were aiming reduce the weight of the Protos 500 and it realy worked.
The prototypes now have been over a great number of flights an one single crash (nobody is perfect and even a trained pilot sometimes makes a mistake) and it surpassed all our expectations. The completely constructed machine´s weight without accu amounts 1000g (with original YGE controller, V-Stabi, Savöx SH-1257MG for heckrotor, 3x Savöx SH-1250 MG for swash plate, 2 Spectrum Satelites).
The akku which we used was an SLS ALP 1800-45C with 6S (weight 400g) The smaller accu doesn´t reduce the flying time essentially, because the machine has a lower energy demand due to the lower weight.
All parts for upgrade the Protos 500 are available.
You can order this parts from the list on this page.
For reaching the low weight of 1000g without accu you have to use the following tuning parts from MSH and the given RC components.

MSH Mainshaft holow (MSH51004) 28,8g
