Nic, you are an absolutely brilliant designer! I'm almost apologetic about not building your Mig 3, and now I have a P-39 to build as well. Both these designs should be in my squadron very soon!

Great plane, the plans are just a work of art, the effort you (and sponz) put into your plans

is very awe inspiring and very professional looking.


DETAILS

Hi friends.



The P-39 was suggested to me by John Zach after the FMS 980mm version was announced a few months back. I thought it looked cool and I liked the longer fuse and large hstab design. jayz and I both immediately commented that this plane could be a more advanced version of the nnMiG 3. A more stable flyer and potentially more aerobatic. I've been playing around with some new design concepts lately and wanted to incorporate them into this new build.



Here are some of the highlights:



NEW v2 nnSpeedWing

Stronger! Cleaner! True wing taper!

NEW Built in hatch

No more need to mod in a hatch, this design was heavily influenced by jayz's popular hatch mod.

NEW True airfoil tail feathers

The nnA-10 style speed tail feathers will now be a standard on my builds moving forward.

NEW Flaps

My first attempt at designing flaps worked out beautifully with my SpeedWing design.



If you like this design then perhaps youíll like some of my others as well.

Beginner Ė Youíve never flown a plane before, let alone done a scratch build

Novice Ė Youíve flown a plane but have no experience with scratch building

Intermediate Ė Youíve flown and built a few FT style planes before

Advanced Ė Youíve mastered the standard FT build style and are looking for a new challenge

Expert Ė Youíve mastered all build techniques and aren't afraid to improvise or tackle tedious builds



The nnP-39 is an advanced build.



PILOT SKILL

Strong intermediate

FAQ

Is the nnP-39 a swappable?

Yes.


How scale is the nnP-39?

All proportions are scale except the vstab. I increased it by about 10% for stability.



Is the nnP-39 a good plane for a beginner to fly?

No. It is an advanced build and requires an intermediate pilot to fly.



I only see a speed wing in the plans, will there be a basic wing also?

No.



Do I have to add flaps?

Nope, they are fully optional.



There is a plane I want you to design, whatís the best way to suggest it to you?

REVIEW

STALLS

Tips stalls at slow speed will occur. They arenít very bad and with very little effort you can recover.



WIND

Wind performance is great. There are no issues in the wind at all.



LAUNCHING/LANDING

Youíll need about half throttle to launch and landing is not bad on the basic electronics. If youíre running the Tacon motor launch and land with flaps.



ACROBATICS

Rolls, loops, and inverted are solid.



SLOW SPEED PERFORMANCE

On the basic electronics slow speed is good. With flaps, itís great. With the Tacon.. heck, why are you flying slow with the Tacon setup?



LOOK AND FEEL

The nnP-39 has a unique look with the aft intake. Iíve gotten many compliments about how smoothly it tracks and gently it lands. The wing root fairings add a nice scale touch and help with aerodynamics. Like my nnMiG 3, the feel of the speedwing is like no other DTFB plane Iíve flown. You can really feel the weight of the plane. It doesnít feel floaty or impacted by wind. It just does what you control it to do. The controls are responsive and crisp and the plane has follow through. Inputs carry weight and you can feel it as you fly. Itís not something youíll encounter flying other DTFB planes.



FINAL COMMENTS



The nnP-39 is a super sleek, extremely fast, and exciting plane to fly. Flight characteristics are solid but donít expect a floaty trainer experience. This is an advanced build and will take a strong intermediate pilot to fly safely and well. The basic electronics provide very good performance and for those daring enough the Tacon setup will let you rip it at 120mph.



Thanks for checking out the nnP-39! If you built a nnP-39 and enjoyed it please consider donating a few bucks so I can buy more supplies to make more great planes.

Hey Nic, what do you think is the best plane you have designed for a beginner scratch builder. I have built a few FT planes but not from scratch, and am not a beginner flyer. I want to eventually build this plane after I get a few builds done. Great job, keep it up.

Nic,

I'm anxiously awaiting your MiG-3 release from Flite Test...

Are there any plans afoot on FT doing a version of this superlative design

My nnChipmunk would be a great build. The belly has a little bevel that can be a little tricky but it's not hard. It's a great flyer and uses the same build techniques as FT planes.

As of now only my MiG has made its way to the FT sphere. I'm looking into the possibility of making my own kits.. So stay tuned for that :-)

Sort of. I have the pod in the nnMig 3 now but the nnP39 is still in one piece. (I know late answer, but just saw this)

Just to clarify, the Brooklyn Bum wasn't my build but rather someone from the community!
