My Ascot - F3B (16/05/2007)

Before Sinsheim show (March 2007) I got my new Ascot. Took me quite long time to finish it (3 weeks) but I don't like building my models in hurry and in Ascot there were many points which I decided to solve with big care. Seems to me all this effort payed off.

First of all Vaclav Vojtisek (designer and producers of Ascot) made huge step forward in wing construction. New main spar construction lowered weight but increased stiffness, sandwich (carbon-rohacell-carbon) ribs make wing again much stiffer than in Viking (did you anytime experienced soft wings at Viking? Me never...), new V-tail inner layout change (full carbon on request), complete carbon fuselage and many other details changed comparing to very successful Viking. Its needless to talk about famous quality of VV model craftsmanship.

Detail which I really like is removable ballast tube. Took me more than week thinking how to keep tube removable. Lets see if my effort will pay off. My Ascot is a bit special F3B version and flying weight with CG 102-103mm is about 2140g incl. altitude logger. I essey to build light. Lets look bellow at some details of my Ascot building.

Using templates of JR DS3781 high speed servos I was trying to find best way to position them and still keep ballast tube removable...
...at the end its working
Using robust plywood rib and some carbon rovings I made platform for V tail servos

In F3X toy there is never enough space. Main switch is from top fuse side, under servos; you will spare space and don't have to search switch rotating whole glider to switch ON/OFF
I used GP 1300mAh NiMh batteries as Rx source. They are small, very hard, but have no big capacity. Forget on whole day F3F flying on slope. This is reason while pack is removable-using HQ gold connectors
Inner cabling
Im using voltspy with LED scale. As I said, GP1300 are good but voltage drop at the end is deadly steep. When 3-rd LED is on full crow blinking I charge or replace pack
LED is even visible from top side. Very often even using voltspy didnt saved model while nobody was checking voltage rotating whole glider
Full equipped nose
Volz WingMaxx HP, using for years and no reason to switch over
WingMaxxes are glued in wings using UHU Acrylit Plus. Within 20 minutes is glue rock hard
Wing connectors are in front of wing joiner. No hassle with cables and wing joiner
No balsa spar on wing, full carbon
Setting up flap position...
...and result
