bass3587 thanks

futabafreak, your right

watch this one...

how could i compare ? i need a radar reading while flying slow !

--the plane run at 5oz loading per square foot

--it use the highest lift type of wing:

unless they hovering, i dont think that most of other type of
wing can compete with Deep Chamber-High Lift-Low Speed-Thin Wing Section-Good For Transport, Freighter and Bomber Planes ?

My e-flight Jenny is slower. In a small ammount of wind i can make it stand still. %to 7mph and i can make it go in reverse!

i agree ! didnt know this bird, same weight than mine (8oz)
http://www.amainhobbies.com/product_...ducts_id/20710
same wing configuration X2
E-Flight Jenny flies (6 min 25 sec)


i can also stand still with low wind when i use
my 2s700 lipo...but i let you win anyway

only one problem for us, AP guys (aerial photography),
its hard to find a good spot to locate a camera on your
biplane ?

Tis a good plane. I use a e-flight 800 mah pack in mine. with no wind i can fly her at 1/4 to 1/3 throttle for 18 to 22 minutes. I also added about 1/8 oz weight to the nose because at anything over 1/3 throttle she climbs straight up.

I mean I had a powered glider that would do like 9 mph and stay up it was so light and
than again its the slowest I have ever seen but there's got to be some one out there thats saying well Ive seen a plane slower than that, thats not a slow plane...you get the jest.

You might have a thrust angle problem. If the tail is dragging in slow speed, but not high speed I would imagine a CG issue. If the plane goes verticle with higher thrust it is probably a thrust angle/trim issue. I had the exact same problem with my SE5a by Tony65x55, once i corrected that she flew great.

yup, tail-heavy


could be a bit heavy in the tail...thrust angle maybe, also,if straight up at throttle. nice plane, trim that baby out,boy. Al
