Dynam F4F Hellcat

Cool Voodoo
That's what I get with the 3000. The 2500 l have 1/2 once actually taped to the battery end and am actually a tad nose heavy. Dose this sounds right to you. I know everyone says it dosnt need flaps but I would really love to do this mod. I'm not experienced with things like this since I've only been in foam for around a year and half now. Came back to flying after 20 years a little over a couple of years ago. Started back with nitro. Do you have any ideas on this. If so it would be appreciated.

I have 2 of the DYNAM F6Fs, one new with the retracts, and one I bought" well used "with no landing gear. Interestingly, they both balance perfectly with Admiral 4S 4000 pushed full forward, and no lead. The no landing gear one is the better flyer, because of its lighter weight. The 4000mah gives me 10 minute flights with 3.8 residual voltage.

[Dewey H Lee]

Hey Ryan. Did you have to add much weight on the F6f the you had in the video. Both farmflyer and myself are coming up with a wide spread. Any information would be helpful.

[Dewey H Lee]

Cool. They installed what appears to be 1/8th inch carbon or plastic strip in mine. I was impressed. Even on the Corsair there was nothing and I had to put in a strip to correct a cupping in it. Came cupped out of the box. Nice to see the strip on what's considered on an entry level plane.

My mistake the groove was on the horizontal stab nothing in the groove so I'll put a rod in. I wish you good luck on your flying today!

[Dewey H Lee]

Farmflyer. No I didn't have anything there. On the horizontal there's a slot that they installed a flat strip there. On the vertical though I did drill straight down from the center of the stab to the back edge of last hard point and install 1/16 carbon fiber rod. The only reason for this is I like running out on the mains during tradeoff and when landing. I fly off of grass at our club. The rake on the mains for this bird does not look like it's going to like landing on grass to well. So I put in a little protection in case of nose overs. My HZ Corsair had a little trouble with grass even after bending the gear forward. Finally I ended up cracking the vertical one day and done the same operation 😷on it for added protection other than just glueing it back. I had decided to do this afternoon konrad mentioning how straight up the rake is. I also added a little more elevator to help. Hope to get to the field today and find out😨. Man I want to get it up. Field opens at one. Plan to be there around 2:30. Forecast calls for the winds 9 to 12 mph. Should be GREAT.😎

One other thing on the cg I'm coming up with the 70to75mm to be just behind the panel line right behind the retract mount plate with the plane inverted wheels up.

Dewey, The differences in weight to balance the same plane kinda baffle me I can see small differences due to many causes,slight difference in foam density,modifications, different batteries, or just how it's placed on the balancer even the size of the finger it set on. What I don't understand is the large differences you see in some models like this 1/2oz to 2.5 oz is a lot. Maybe someone from MRC or someone else out there can give some insight on this. On the flight stabilizers I have not used one so I can't help much there. I'm hoping to get a maiden soon weather is a beast this time of year here winds 25to35 gusting over 40 is forcast for the next few days so I don't see it happening this week. The build was easier than my other Dynams this one is a better quality kit. I also have to reset the motor timing it's got the good old low rpm surge. Dewey did your vertical stab have some type of brace installed mine had a groove cut for one but wasn't installed I'll get a carbon fiber rod to install in the future.

Mine falls so close to dead in the middle with a 3000 admiral. The 2500 all the way shows 1/2 to 3/4 of an ounce needed. My hands and eyes are so bad I have trouble getting my planes on my great plains balancer. Most of the time I have to get a little help😳. Had a hard life and a lot of injuries. Lost a 1/2 inch off my right hand middle finger last month to a table saw. Anyhow only other thing in the hatch are my tactic 826 and a3l gyro. I fly both spektrum and tactic. Never had a problem with my spectrum but my dx6 limited me on options I want to use. So needing more channels the price and functions of the tactic 850 was to hard to beat. I have noticed that in other post you fly tactic also. I was wondering if you have talked with anyone using one of the 2 slider switches on the side to set the gains on the a3l. I have not done this with my tactic yet but planning to with the hellcat. Have been unable to with the spektum due to the lack of channels and still get all the functions on my planes to work. Anyhow I don't know why all the difference with the added ballist. Sure seems like a lot. Hey if that's what it takes for your way of flying. Got me worried if I've made a misstake. I'll definitely go back and check mine on the great planes and fingers. I have found a difference in the past. Hope your maiden goes well. Hope to get the flight review soon.

It's looking like 2.5 to 3 oz lead in the nose to balance at 70mm with a 2500 4s admiral. Could probably get by with 1oz less if I had the 3000. Is this close to what the rest of you are using?

[Dewey H Lee]

Exactly what I done. Great move

[farmflyer]

I've also heard this. I asked Ryan about the one they reviewed he said they had no problems with it. After I get cg set I'm going to put a little foam tac on the magnets so maybe if I have to remove it there will be less damage.

[Dewey H Lee]

Hey Farmflyer
I just remembered about someone talking about the cowl coming loose. I don't know if maybe they haven't balanced the prop setting up excessive vibration causeing it to vibrate forward or just not seated good. Mine fits snug but the magnets really don't seem to be holding well. I have used a couple drops of foam tack to be safe.

[Dewey H Lee]

Shoot, was hoping for a blooper😁 . Does anything ever happen during a review. If so it would be cool to have review on that. Been a lot on YouTube showing misshaps but not with anyone you admirer.

Hey Ryan
Just out of curiosity. The video for the the 1400 mm corsair. Was that the wheel falling off on takeoff. First time I noticed it and then I heard in the background hurry hurry??????? 😏😏😏😏

lol No, it was a clump of grass.

My corsairs the Parkzone and Flyzone getting the Dynam next.

[Dewey H Lee]

By the way. 2 corsairs also. Hobby Zone F4F S and the 1450 AIRFIELD F4F. Going to get the 1700mm FMS soon. Just been so many problems with them though. The AIRFIELDs been a good plane except the retracts and parts availability. NP did send me a new wing though when the retract collapsed on maiden take off.

[Dewey H Lee]

I know man. That's definitely a man's plane. Just matches our egos😁.

[farmflyer]

I've only got one mustang the dynam. My only multiple the Corsair I have 2 soon to be 3. The hellcat appears to be a little better quality than my other Dynams I'm hoping to get it built and do the maiden flight in the next week. I was a little suprised how big the fuse is I can't get the grin off my face.
