Hi guy’s
I have just completed a SAVEX L-39 EDF.
One of the things I have never flown with are flaps.
Is there a good book or detailed instruction that someone has on the flying of Jets that walks you through a maiden flight ?

Thanks for any help.

Flight simulator software like G3 would be the best suggestion I could make...

If you have a JR 10X, use flight modes... Mode 1 take off, Mode 2 flight, Mode three landing. The sweet thing about is that you can trim the bird for each mode.. Or, make sure CG is correct, take her up high and drop the flaps and see how it reacts at different power settings.

My 2 cents..

One tidbit of information I pass on to potential jet freeks, if you see enough value in building a turbine or high end airplane like that EDF you've got there, you are more than likely ready to fly such an animal.

Very rare does someone put together a good looking jet and then not have the skill to tackle it.

So run with the odds and have a blast!

I suggest that you fly it without flaps first. During your first few flights make the triming and get use to the plane. Then you start using the flaps etc... my 2 cents

How did your L-39 fly on edf.
I have one I'm converting right now. I ordered two and flew the first with a wren and now for edf.
What fan, batteries and intake did you use?

thanks in advance

What he said..........

you will be ok. just play with the flaps at a higher altitude and figure out that bird. Stall ect

That was 3 1/2 years ago. Hopefully he's flown it by now

I would use flaps.
I have hundreds of flights on Savex L39 and you should remember, it has a fairly high wing loading.

As EDF you do not have the advantage of landing ‘lighter’ than take off.
Use around 5 deg of flap for take off and around 45 deg for landing.
Combine the landing flap with around 1 to 2 mm of down trim.
When setting up the flaps, ensure each side move exactly the same.

As you decelerate to landing, on the downwind leg, deploy takeoff flap and continue to decelerate.
Make you cross wind turn and deploy main landing flap.
By doing this on the crosswind leg you can ‘read’ the rate of descent and speed.
Be prepared to add power, the landing flap ‘really’ slows her down.
Set your rate of descent with power, not elevator.

Make your final turn and adjust power to increase or decrease descent as required.

As has been said, check flaps at altitude first to ensure that they are balanced and to know what to expect!

wow....... how did it end up on the first page..... LOL yeah I hope it has flown by now.......... i was questioning the 3g remark....... cuz 4.5 is out.
