Why the new collet? I like the yellow spinner. I did that last week. Just put on a wooden 13x6 from Master Air Screw. Haven't flown yet but it should be nice. Good luck with maiden.

The collet I hat was all aluminum and the threaded part of the prop shaft was hollow and I guess I was over tightening it and it broke right off.
The hacker has a steel shaft and 4 slits on the part that is compressed onto the motor shaft.

I only had time this morning to go to the schoolyard a block from my house and fly 1 battery through her.
No surprises, she took to the sky easily and after a few trims was flying pretty good.
The 4s1p 2200 45C pack made her ZOOM to the clouds !
I was trying to feel it out and the breeze picked up a little.
She handled the breeze just fine, even with the 3 1/2 ounce weight loss.
But I really wanted to do the fine trimming in the calm winds that I slept through....
I was on the recommended CG and I agree that I will want to move it back a bit.
Also maybe tweak the thrust angles a bit.
There is a specific sequence of maneuvers that you must fly and observe and tweak in order to truly get the plane flying correct, not just good.
I think she really has the potential to fly as good as my bigun.

Also, when flying inverted I noticed that the down elevator (up) was not real responsive ???
Anyone else notice that ?

She will get better !

Remember Jim, it's still a foamie. I think there is a bit of flex in the tail no matter what you do. So, on "rails" may be a little too much to expect from this one but for the price it really is a nice addition to the hangar. When I think of the time and effort I put into my Art Tech Yak 54 for the same $ and nothing close to the results I've had with this model this Dynam really is a great value.

Very Nice! What kind of paint did you use? I wasn't real big on "Peaks" either and considered getting a set of Python stickers but that would have increased the price of this terrific value! So I settled, they are growing on me and I do like the yellow. I only wish Dynam and Nitro would kick us all a little commission since we all "sell" one of these each time someone new sees them fly!

Not noticeably! I was only kidding about that. The wooden prop will likely help sin e the Dynam prop was pretty flexible.

I used Min Wax Polyacrylic, it is water based will not hurt anything!
I used a foam brush to apply, dries fairly quick between coats, water evaporates and I do not believe it weighs enough on this size bird to change anything.

I do have some 4C in mail for the big Waco so will be sure and use them on next try.

Tim make sure you have a batt strap mounted and some Velcro in the batt compartment. You may have also had an aft shift of your batt on takeoff that would compound your pitch up after takeoff. The cg really shouldn't be that sensitive on this plane. I've run mine at book cg, fwd and aft. Pretty much all over that batt hatch and it still flies nice. Double check your control surfaces to make sure they are all neutral, if you have dual rates set up 50% low rates and throw some expo in if you have it. One last suggestion, have some runway space for the maiden and when you do your take off roll go easy on the elevator. If it wants to "jump" into the air or if you feel you have to "pull" it off the ground at proper flying speed abort your takeoff and double check all the above. Cg should be roughly 1/3 to 1/2 way back from leading edge of wing (top on this one) of any plane. About where a wing spar will be.
It's easy to over control and yank an unbalanced / unstable airplane into the air only to find out it is way out of balance when you "relax" the controls from takeoff. Go easy, rotate slowly and notice what it is doing. At full power with a 4 cell takeoff roll is 5-10 feet! Good luck.

Tnx, the crash was my problem for sure, I was flying T-28 and Albatros just before and they are different birds altogether. The battery was secured, I even use a balsa block behind battery as extra insurance and a velco strap.
Thinking back I probably gave it full throttle and had it on high rate, it just got ahead of my 66 yr old thumbs!
I have done some light reenforcing around wing and landing gear retainers also went to socket head #4 screws a bit longer than in kit for wing and landing gear.
The balsa block behind motor mount was a good addition as I see no damage from landing prop first!

I used Min Wax Polyacrylic,applied with a foam brush the red is a sharpie marker, the graphics are black sharpie marker .and i agree there are four members of my cub with this ship. i was the first to get one ,since i love biplanes. i got the red one first i gave it away to a member of the club . so now there are 3 yellow ones and a red one .
