How much forward you will be placing the engine?

Mugu

I guessed it when i see your wing tubes that you will be placing it in the rear.
This is how the first generation CARF Mig-15 had the engine...it makes very big problem in balancing.
It needed more than 3kg in nose to balance correct . Maybe you would like to do a google search about it...it was big problem

They changed the design and move engine forward:

MiG-15 Fagot 1:5

" The turbine has been moved forward by considerable 30 cm (12"). This gurantees that less balance lead is required to obtain the correct CG. ."

Now many owners including me we are moving even more forward the engine to eliminate the use of balancing lead.
I flew some Mig15's and the ones with this modification fly 100% better..lighter and less stress to the landing gear..

I can send you photos of the engine frames i made if u r interesting .
Again congratulations to your amazing skills and mig!

Mugu

and you tubes from the wings how go in the fuselage ?
i will fly like this now and i will see how much balancing need in nouse ,next ones i will change for good balancing😊.thank you

Here is my design for the CARF MIG-15.
Maybe one day i will brake out the frond frame and make new following the - - - - - - - - - - lines.
For two reasons. It allows room for bigger turbine like p160 ,the ideal engine for the CARF size as the p100 cant loop it.
It allows room to raise the engine to have "neutral thrust" as the normal mounting gives "up thrust".

made out of multiple sheets of 3mm ply




Closing the pocket.Its oversized as seen in the draw to give room for alingment .In there you put the fibreglass tubes u have already made and fill all pocket with epoxy

Mugu

thank you ! 😊 i'm very curios how will fly this bird .

My Feedback: (23)

last photo is the carbon wing tubes... if you ever need to make this modification ,it would be good to cut a small line across the the tube so the air can come out while you inserting it.
Or while resin is still fresh you risk to pump air in the pocket when inserting or vacuum resin in the fibreglass tube while you remove it.

sorry for the poor english ..good luck!

Mugu the Flytechnique Mig have the turbine forward than yours and need some lead on the nose. About 300g.

Mugu

aha 👍

gapellegrini

You will need a lot more than 300. Flytechnique turbine is 12 inches ahead than yours.

Mugu

i think 600 or more ! 😬

Mugu

after i fly the prototipe i will make changes

I have fly quite a few jet models .I guaranty your. mig will fly absolutely amazing .The wing is just huge.
Just keep it light and use a p160 engine.

You might want to look also the last frame supporting the fin that goes all the way in fuselage.

and here is internal wing support of carf as suggestion



goodluck
