"I used an MVVS .77 engine with a full length tuned
pipe. This is
an
outstanding engine that really gets up and goes when it is "on the
pipe." The engine starts nicely and idles very low. Transition is
awesome.
It appears to produce plenty of power for anything I know how to do. I
initially
mounted the engine sideways to put the pipe on top but experienced
loading up as
the excess oil in the pipe ran back down into the engine. So,
subsequent the
picture, I mounted it upright and the pipe is now about 3" right of
centerline. The good part is the cowl now fits nicely and looks great.
"I mounted the 1100 Ma 6 volt battery in the rear
compartment with
the
receiver, switch (on bottom with in being on), and nosewheel steering
servo. I
put a 16 oz. Dubro gas tank in the front and mounted the throttle servo
sideways
against the back of the forward compartment. With the minor servo
shifting mods
I made and the fact that the MVVS .77 is a light weight powerhouse, I
did not
have to add any weight for a perfect CG balance at the forward CG limit
(22").
"For servos, I used Hitec 605's for elevons and JR 537
elsewere. I
used
dual rudder servos and programmed the plane for rudder speed brakes
with my JR
8103.
"The Delta flies great. The is no pitching moment
cause by
deployment of
the air brakes and it really slows down nicely. In fact, I need to keep
a little
throttle on until touch down. When landing without speed brakes, I
usually just
flair hard at about 2-3" off the ground and it creates a soft landing
that
looks cool. Because I fly off grass that is thick and often a little
long, I
cannot use a 14" prop and instead use a 13x8 which work great for the
engine. Also, I find that I need to pull back about a quarter stick
after
gaining some speed on takeoff just to lighten the drag the grass creats
on the
nosewheel.
"Check out my hold backs made with: 2x4 wood, broom
handle, 2 long (6")
aluminum nails used for hanging roof gutters, and some kids swimming
pool noodle
foam thingy. They work great and comply with my club's rules for hold
backs."
