Hi guy's

Just completed a Hobby King Skyfun, ready for test flight, but i am concerned about the prop hitting a hand.

I have been working on a dolly for the last couple of days, tried it in the back yard ( very bumpy) and found it left the dolly to easily, though the field at NMAA club (Rosebud Vic) is a lot smoother.

I wondered if anyone has got a design that works ?

Modified with a EDF 2816 4600Kva with a 5.47 x5.47 prop SS 40amp ESC pulls 30 amps on 3S 2200 if i go to 4s jumps to 70 amps so will have to change ESC :-) but that's in the future.

Getting on a bit in years now and not quite so fast on the sticks, and a solo hand launch is scary.

My HK JetTiger ( modified motor ) flies well on 1500 3s even though it's a short time in the air.

Currently using the ASSAN 2.4 modules on JR388s X 4 of the blighters,
that's 32 model memory available and i am still ripping out receivers for new projects.

New box on the lounge floor ( HK 1.6 meter J3 clipped wing Cub the $114 version)at least i have all the stuff to complete it :-)

Reason for the post is to get some suggestions for a dolly or find out if someone has a working prototype.

Cheers TBBW

I haven't actually built a dolly setup yet for the a bumpy ground as i hand launch mine and i understand your concern as you need to be a little quick on your fingers if your doing it your self.

I was Toying on the idea on paper and not sure if i have heard someone talk about it before too.
But using three pen like rods off the dolly that go into the planes belly via larger hole size and goes in quite a bit so it plane does not bounce out but hole bigger enough so once it leaves the ground the dolly falls out.
Pen like rods will required to be on some forward angle and dolly needs to be quite heavy so it does fall off plane.

I can try to sketch something up if need be if my wording is confusing.

Heh i may end up Building one as our Field is Bumpy and would be a bit of fun taking off from ground.

Only issues i can see is Steering which may have to be some sort of easy unplug with a front dolly wheel thats servo steerable and have to be some distance from ground as prop may hit ground on incline.

Or Do This
