Great job. I'm thinking of picking up the latest iteration of this plane and have really enjoyed this series of reviews. Any chance you'd revisit the Dynam Spitfire since they've made some tweaks (I think paint for sure) and the plane in the videos is no more? Either way, thanks for the great content.
Thanks for watching. I don’t see a Dynam Spitfire in my future again unless Bitgo wants to sponsor one for me which is possible. I don’t think they change the fundamental aerodynamics in the revisions so most of what you see here should apply on v2. Maybe motor/ESC upgrades.
Wheel axles need to be in line with wing leading edge (as much as possible) , hard to do because of wing/gear mount geometry. Need to take off with elevator up at start of takeoff then release to let tail rise and let speed build until scale-like lift off. Yes, must have cooling air flow past motor and ESC and exhaust. Land with some power on, do wheel landing and raise elevator to keep tail down during roll out. My Tower P51 must have up elevator to keep tail down during takeoff then release and accelerate gradually until lift off. Smallish wheels struggle with grass. Use 4S and experiment with props and CG.
I would cut out some small holes on the sides right behind the prop, and glue some kind of scoops to ram the air into where the ESC & receiver is. I don't think there is any kind of ventilation in the back either, but it wouldn't be too hard to add some vent holes in the rear. That should get enough air in there to keep stuff cool. From what I have read on several sites, they have a tendency to nose over a lot, so they use some elevator to keep it from nosing over. If I find anything, I will definitely let you know. I'm going to change the ESC to a 50A or higher to be able to use a 4S LiPo battery pack. I'm going to play with the stock motor, and if it acts up, I will change it out.
Ive owned this plane for several years and it has remained hanging - until I purchased the 1600mm Flightline. Before my Flightline maiden I wanted to hone my spitfire skills. Ive been modifying the darn thing to make it flyable for weeks now.
@@RCVideoReviews I added a bunch of weight to get the CG where it needs to be. I carved out the battery compartment to accommodate a larger battery and added lead strips to the underside of the nose. I also opened up the front end for ventilation and did exactly as you did with the exit hole in the rear (looks identical to yours before I watched your video). Im not a fan of how the prop collet attaches so I had to roughen up the motor shaft a bit. She's balanced perfectly and passed the run up test at 9 minutes - now its just a matter of finding some time to maiden her. I could have saved some brain time if I had seen your video a month ago.
Great video man, I have the Dynam 1200mm BF109, they have put very nice air openings in it. I have a tough time with the narrow track landing gear, it could also use flaps for landing, very fast landing speed. Other than that though I love the BF109, highly recommend it. - I used to live in Chanlder, AZ., I understand the heat.
Thanks for sharing, Great informative vid, Your nose overs seem to me (partly) because your giving too much power without enough ground speed, build the speed more gradually, the prop is trying too hard to drag the plane behind it in such a short distance, build the speed up over a longer distance, I've found by holding the elevator up it begs for problems when a gust of wind catch's the plane, causing an instant UP situation, (as I have experienced) as for the 4s, running the 3s esc on 4s was always going to be a high risk situation with heating problems, I have around 20 3s battery's and one of the reasons I'm looking at this plane is solely to run on 3s, I already have many HIGH speed foamy's I'm not interested at all in making mine a fast 4s spit, maybe the heading should be, "my Modified dynam 1200mm spitfire on 4s maiden" have a great day :-D
These Spitfire vids have been very helpful thank you, I’m glad I watched them before I build mine
Awesome! I'm glad you found them helpful.

@@RCVideoReviews I'm sure that's true, just wouldn't mind seeing more videos of the plane. :) Thanks so much for responding.

Good informative video! Did you do any mods to the stock motor/ esc to use a 4S?
Stock motor and upgraded to a 50a esc.

It flies great--it's the ground handling and heat management that are the issues I found. What changes have you made?

Good luck with the maiden. Be careful on the ground--it's tippy.

have you thought about using a esc with a reverse so you will be able to reverse prop to avoid ropll over.
somebody else mentioned that too. unfortunately this plane didn’t survive so I can’t test the concept. Good suggestion though.
@@RCVideoReviews buy the Flightline 1600mm version.
what about having a reverse on your spitfire . When it starts to go over on landing simply reverse ptop for breaking.
That might work. Unfortunately this plane didn’t survive so I can’t test it.

fly on a paved runway
Didn’t help.
