Indoor Jedi Star Fighter

Hello guys, not pics yet but the las saturday I tried to fly the new plane in the fleet, a styrofoam JSF, 9" w.s with JMP receiver and std. actuators, powered by M20 7:1 geared, 10 cm blue prop, but the plane is some hard to fly, it has camber and reflex in the delta wing, and is unpowered, once I got the correct trib, only flew half circle.... do you can tell me an advice to get more power?

The JSF weighs 26.2 grams and have a WL of 2.6 oz/sq. ft. I thought to replace the motor, to use the N20 with DD u80 prop.

Thanks.

Alf

Maybe to omcuh drag in the airframe. Also, the Jedi Starfighter lacks proper vertical stabalization. Is this the new starfighter or the older one, IE does it have a TIE-fighter canopy in the middle, or is it a long triangle?
I believe all the trim you put on it added too much drag, so you need an alternate form of stability; adding a clear plastic v-stab underneath/on top will help stability.

Very interesting. I have heard of other larger (cd rom brushless i think) jedi starfighter projects in RC groups, one had some success, profile body/depron. It is basically a delta and should be easy to 'make' it fly. I can't help you with the power system but i'd like to wish you luck. I had built some sp400 powered Millenium falcons, had some success but still in the process of finishing my new one, hopefully to fly better with some brushless urge. Thanks, you have encouraged me to get back on my millenium falcon project. Good luck with yours!!

Is the older one, profile fuselage and delta wing, the stability is not problem, the profile cockpit serves as a rudder, the foamy is 3mm, so the drag is small, the real rpoblem is the low power, it can not mantain the flight.

Thanks.

I see. You may need a geared n20 or even a small brushless :-)

I think in N20, as the receiver is the JMP with one 145 mah cell I can not to use the brushless

Cheers

I use the Blue 10cm prop with the kenway gearbox which is 4.2-1 and I think it produces more thrust than the N-20 geared or direct drive. Make sure you put a small drop of oil on the bushings of the gearbox and on the motor bushings. This has to be done about every 8 or ten flights. You also need a fresh 250 ma battery to get max power from this set up. I don't think the 170ma or smaller can maintain enough current to give you maximum output.

sorta-x-wing

i built this when the plantraco equipment first came out. i loved the X-Wing look of star wars, but thought i'd give it my own twist, and this is what came out. i wanted it to have some unconventional looking wings, even if that meant sacrificing total wing area, so i put on 4 wings instead. i put on a penny for a glide test, not knowing how it would really fly, but surprisingly it glided rather well, much further than i expected. i know the standard micro equipment will be too heavy, but the .38g plantraco rx, with .6 gram actuators, 4mm or 6mm DD motor and 30mah lipo, the AUW should be low enough to not make uncontrollably fast. unfortunately, i dont have the plantraco equipment yet, so it's still just a glider, but someday...

Hi guys, I changed the M20 motor for an N20 with the same 7:1 gear and the 12 cm blue prop, not fly yet but the power "sense" more, I hope to get the flight now
Dan thanks for the oil advice I going to do it
Micro, nice glider, complex and unexpected design it is, maybe in a near future flight RC it will... I love the Joda style

In june 18 and 19 will be the SW Guadalajara convention, I wish to build a lot of gliders for the kids, I think in the A wing, JSF from E2 and E3 and to get the flight handle in the RC small version, in next days the report

Actually, there is two threads on the millenium falcon in the Parkflyer section, all progress is there. I am not the only one who has built one, but the thread starter has had the most successful flying so far.

From my flights, it handled rather well, but trimming it up is rather hard and i had a fair few crashes. I hope to return with #2 and a Brushless motor someday, it has a larger wing area which will help.

Yesterday, i tried a micro falcon with a 1 channel rx to imitate the JMP, flew fine and glided nicely, i installed some actuators but the contol surface were too small, but i think rudder will be alot easier to make and will work much better. Obviously, the verticle stabilzer/rudder shows clearly, but some clear plastic will do next time.
Just someday...she'll fly..

Hey Alfredo- Do you have plans for the FF A-wing? Or a good 3-view?
