Gazz, i guess the reason why i have taken so long with this build is because i have been yessing and noing myself about lots of things in regards to the build.
As Simple as it looks it reality there are a lot of decisions i guess in the way you build it, which you and rob will realize, unless I'm just looking too deeply into the build and should just throw it together as is.
But with a lot of reading up on it, main Issues was COG, Tip Stalling, elevator controls failing,
1.
I had concerns with weight, cog etc as lot of people say keep it light or you will have grief as it will tip stall very very easy.
So motor weight and lipo weight was a consideration i had to work on.
This is the reason you see on my Viper belly opening is longer than standard. as i pushed my motor to the rear 4 inches more so the lipo weight will balance out the cog a lot better with the lipos I'm using.
which i hope i have worked out OK and give me good flight time.
2.
My other issue which stop my build basically was i could not decide to fit retracts and Flaps or just maiden without and see how it flies First and then add them in later. Will it be easy to add later ? but if i install all of it will it add extra weight that isn't wanted ? and affect flight ?
Are Flaps really necessary to use on the viper as you have to come in hot any way, is going to help a whole lot ?
With all the discussions i read there is no mention of any one using flaps on landing, a couple have mentioned they use it for take off but doesn't really need it. especially if you bun geeing.
and the weight of the flaps, 50gms including wiring, fixins etc is not much but adds up in the whole scheme of things
Retracts could be good in help slowing down viper on the grass and good for area 51 and take off from grass, but extra weight which would be approx 250gms installed is a bit considering thats half my lipo weight.
But in saying all this should i just throw all the bells and whistles in the build and just fly it ?
Has that confused you all or am i just confusing the matter
