NitroPlanes' Dynam Spitfire Revisited.. Try try again!

The NitroPlanes' Dynam Spitfire proved troublesome for me in my last video with 2 crashes! Here are the mods I had to make and the results of my efforts, as I don't give up easily.
The Vertical tail was too small, the nose is too short, the landing gear is too far back, and the bottom of the wing is "dirty". Balancing this plane is essential.




I usually can fly anything, but this Dynam Spitfire has me perplexed. Reducing throws as far as possible, trying to balance it, and being delicate on the controls was futile in my first video.
The slightest up elevator causes an immediate tip stall and the plane flies really "Pitchy" with the extra nose weight in or not.
The motor is stout and the plane is beautiful. Here is the price and availability link

I have not heard from Nitroplanes since I made the last video, so did all these mods and replaced the speed controller on my own.

this is the same problem as the HBK2 and has the same solution :) use the same size lipo as the manufacturers were using when they made this plane :) rather than put in 11oz of dead weight and lower run times put in a bigger lipo further forward and increase flight times :) simples :D

The bigger lipo, I tried on the last flight in the other video and it is as far forward as it can go. It is a really short nose if you look. First it barely fit in and then there was no room for the clay. The bigger Battery only weighed 5 ounces. Definitely not enough.

I,ve been saying it for years Dave, They make it,we make it better.

As far as I am concerned, when you buy a PNP, you shouldn't make any mod to improve upon its flying ability, when you have to do so, those guys making the planes are not doing their job, since this vid is almost 2 yrs old, I hope Dynam has since improved on their products , awesome job on the mods!

Good job on this one, very impressive!

[toolbaggers]

it looks kinda like a p40 now

[fishstick0071]

love your stuff!

[SlyDawg951]

Wow Nitroplanes should start to send you All the New models to you to be TESTED from Now On! That was Great, what is that rule besides the Lemon law, I think what is going wrong will go wrong, i think?

Dave. Again good video on this 1. thanks for the heads up on CG. I personnaly dont like Dynam plans. cheap and very unflyable with out a lot of mods. My latest from them and NP was the SR trainer. very poor out the box. Now wing support ie: Spar that i could see, just a thin white straw, so i had to reinforce with 2 carbon rod's 1 on the leading edge 1 on the trailing edge, Oh and a new motor as the shaft on the stock broke easly on landing, and they dont carry a spare.

ugly but it works! i rebuilt the front of a micro mustang with a styrofoam cup just so my friend could fly with me!
