Hello Ron,
MRC has support and video tabs you can reference when you are checking out a certain airframe.
Pilot Ryan in his videos talks to your CG question.
Check it out.............     http://www.motionrc.com/dynam-supermarine-spitfire-1200mm-47-wingspan-pnp/#description
Good luck and best regards,

RE: Dynam Supermarine Spitfire

I have one. Cg at 70 to 75 mm back from leading edge at wing root. 1 oz lead behind the spinner using a 2600 admiral 3s or 2500 4s admiral all the way forward mine is a little nose heavy there. I also cut air vents on the bottom of the fuse under the nose and on the bottom behind the cockpit just in front of the inner brace you can see inside. Shim the landing gear forward and sand the fuse behind the spinner to allow the collet to bottom out. I also use a file to scuff the motor shaft to prevent the collet from working off. I have really enjoyed flying this plane I didn't install the flaps I don't think it needs them.

RE: Dynam Supermarine Spitfire

Ron the Dynam models are famous for gear problems in temperature under 50 . So your right about getting home and it working great . 

Not sure where your at but you may keep that in mind . I have 5 or 6 Dynams and enjoy them all . 

Keep us up on how it goes .......

RE: Dynam Supermarine Spitfire

Anybody know why the gears are sensitive to the cold? Is it that the grease gets too viscose at the lower temps adding drag to the gear train? Anybody run the retracts dry to see if reliability improves?

All the best,
Konrad

RE: Dynam Supermarine Spitfire

brian I am in dallas area so no way was it below 50 lol....I have a t28 that I had run with the gear switch up on the tx maybe when the spits was turned on the gear didn't like switch position because they went up but wouldn't come down...

RE: Dynam Supermarine Spitfire

why is the spits so darn slow? ive calabrated the the throttle but seems to be the slowest plane at the field...no need to slow down for those crowd pleasing fly byes lol...ordered a 45a esc today and will try a 4s setup later this month...anyone tried this lately?

[farmflyer]

RE: Dynam Supermarine Spitfire

If flown mine a few times on 4s with stock set up without any issues but I only use short bursts of full throttle. I cut vent holes in the underside of the nose and fuse with these I havent noticed any heating problems. The plane has a lot more speed on 4s. I used an admiral 2500 4s all the way forward with 1/2 oz lead behind the spinner balance seemed good. You will have to trim the sides of the battery compartment to get it in.

RE: Dynam Supermarine Spitfire

I just replaced the ESC to a Gecko 45 and have no issues using a 4-cell battery. There is noticeable difference in performance with a Master Air screw prop and 45 ESC.  I have all the speed I need now. By the way, I am using the Admiral 2200 45C battery.

[Ron1950]

RE: Dynam Supermarine Spitfire

.Pheonix are u still using 3s?

[Ron1950]

RE: Dynam Supermarine Spitfire

I am going to try the 45a esc and 3s first then maybe try the 4s batts if nothing changes with 3 cell

RE: Dynam Supermarine Spitfire

Ron when the gear is open I took my air hose and blew the screw mechanism real good then put some white grease on them . Then I worked them back n fourth . Seems to help some . I do know that MRC has asked them to look into it . 

As long as you have gear with no rotation Dynam offers a upgraded retract . It's in the upgrade tab and they seem to work pretty good also . 

Good luck and keep us up on your progress

RE: Dynam Supermarine Spitfire

just checked the up grade area for the spits OUT OF STOCK of course...I just bought a new set of stock gear maybe they will work for a few flights...

RE: Dynam Supermarine Spitfire

Well never was i so happy to crash and destroy beyond repair a plane. This pos fkew different every flight. Darn thing took off banked left touched down then launched up and over noseing in I was happy to see it go.

Greetings from the Pacific NW,  :cool:

Sorry to hear about your Spitty. I wish I would of ran across this post earlier. I may have been able to help. I have a few Dynam war birds in my inventory and just received this week the Dynam Spit Fire to add to my collection. From experience in owning the Dynam P51 Mustang I may have saved you a major headache. The P51 has the same set up as the Spitty. Not being fast enough I carved in a 4 cell and up graded the ESC. And your right, it was a different plane the whole 4 times I flew on the 4 cell set up, and ended just like your Spitty. WHY? The motor is not designed for the 4 cell pack causing power surges instead of consistent power, Making the plane unpredictable on take offs. I never knew what was going to happen next. Theres 2 ways I have found to increase speed and performance. With the stock 3 cell set up, just simply change the prop to a 12x12 apc single blade. I'm talking a night and day difference in speed and performance with out losing any flight time or over heating the ESC. It dont look as sexy when on the bench, but who can tell when its in the air. The second way is what I'm working on right now. Motor and ESC swap. I'm installing the Dynam SU26 KV650 4 cell motor and a 50 amp ESC. Its all plug and play. In theory my spitty will rip up the skys with long flight times to. I'm staying with the apc 12x12 single blade which combined with the higher out put motor thats designed for a 13x6 single blade, Will be plenty fast and stay very cool. Any longer prop may strike the ground during take offs and landings. Other wise I would use a 13x12 single blade. Hope this helps in the future.  Pacific NW Flyer  :cool:

RE: Dynam Supermarine Spitfire

I have the Spit and the P-51...

No ESC upgrade needed to go 4S.
Just carve foam for a 4S 3000 mah to fit and fly it.

A bit light and low powered on 3S 2000, but they come alive on 4S. They can carry 4S 4400... but performance starts suffering above 4S 3300 due to the weight.

Yea thats what I first thought to, Oh it handled it just fine when all was new. You just keep doing what ur doing. Dont take any advice from us old timers who've been doing it for years. When you burn out the ESC, or have a dead stick landing when the motor surges to screeching halt, I wont say I told ya so. Good luck and Happy flying.

Since its been working in the P-51 for 2 years...

I think you need to shut up.

I've only been flying RC for 40 years... electric replaced all of my glow stuff 9 years ago.
