Sebart Apollo s
Hi I have just got the new Sebart Apollo s 50e here in the UK.
The quality is excellent and everything fits perfectly, it's almost ready to maiden, but it needed 300 grams of weight in the front of the cowling to achieve the CG of 15 centimetres, which is a lot, I used 15 gram servos for elevator and 25 gram servo for rudder, motor is a Turnigy 5055 430 and weights 380 grams, battery is 5200 6s at 580 grams pushed up to the firewall.
Hope to fly it soon when it finally stops raining!!

Joe,
Congrats on getting the ApolloS.
Battery weight seems unusually light. When I flew 50 sized Sebart planes on 6S 5000's they were 700+ grams for 25C - I use Hacker Eco X batteries for my 2M planes and they have great durability and are light, even a 6S Eco X-5000 weights 653g and the 6100mA version weighs 766g. Once you get to fly the plane and can fully determine the best CG for you then you can determine what options are available to eliminate the nose weight - bigger capacity batteries and changing the ruder servo to closed loop are 2 options that come to mind.

Sebart Apollo S 50e
Hi Joe,
I have almost finished assembling one of these.
It appears that I am going to have to put a boat load of lead up front to achieve the balance point !!!
Have you flown yours yet, is the balance point conservative or spot on, in which case I'm going to have to add a lot of weight up front line you've had to do.
I look forward to hearing what your flying experiences were like.
