    K&B 7.5 ducted fan

    Silly question. I acquired one of these. Does your carburetor have a rotating assembly in it like regular glow carbs normally do for throttle? Mine seems to be frozen. BTW this one is for sale. I have a complete fan for it too if anyone is interested, motor makes good compression.

    Finishing up an AJ ARS 300 86" . DLE55 on tap with a 23x8 Falcon, Hitec HSB-9381TH servos. Few more odds and ends to complete, but we're almost there. Waiting on a nice JTEC wrap around muffler.

    Painted up the Estes Big Daddy with the colors of FREEDOM!! Tamiya metallic red and blue, with primer white, and a gloss clear coat for added measure.

    The 'What did you do in your workshop tonight?' thread

    Picked up one of these today at the LHS I work at. Figured I'd dabble a little bit with rockets to keep myself from getting burned out on the airplanes... I get home and suddenly I'm down the rabbit hole doing research on how to get my level 1 cert for a Apogee Rocket's Zephyr o_O:rolleyes:

    Discussion The I’m Going/Went Flying Thread

    Picked up a Night Timber 1.2X the other day. Running Spektrum smart batteries with it for full telemetry. What a trip this thing is, the reverse thrust gets everyone every time. And she flies super rad, totally stable and gets down.

    Xpress builds a 115 AJ Laser - PICTURE HEAVY!

    That was flying at sea level with that prop. Otherwise, I ran a 32x12 and it would still rip it.

    A 31x10 is really too small, I'm spinning a 33x11W.

    I'm fine with an early exit. Don't have much to prove getting down on the ground anymore :cool:

    I've got one on order at the shop I work at. Definitely a need for me.

    Getting used to that 5000ft altitude density here in Tucson. Difficult to transition into when you're so used to 1500ft or less.

    Xpress builds a 115 AJ Laser - PICTURE HEAVY!

    Yes, because it's not a motor anybody is willing to give up. Special order is the only way to really get one now. Every bit as reliable as DA and Jason Doran at ZDZ USA can fully service them if any issues pop up.

    Xpress builds a 115 AJ Laser - PICTURE HEAVY!

    The 180 was the only engine in that class when I purchased it in 2016 (2017?), the 195 was not available at the time. There was an issue with the casting molds for the 180 so the 195 was produced, but it looks like they've cleared up the problems with the 180 molds. The 180 is the better of the...

    Help! Aura 8 setup questions

    Bounce back is basically just when the gyro overcompensates when you release the stick to stop whatever movement the airplane has. So for example, if you are applying full left aileron at high speed, and release the aileron stick suddenly, the gyro will apply a sharp and quick input of right...

    The 'What did you do in your workshop tonight?' thread

    Just giving my measly $0.02 since I know that's about all my opinion is worth, but I've actually had awesome luck using black RTV to make my exhaust gaskets. It's got different properties than the red RTV and holds up a lot better IMO. I've even used the black RTV to plug a smoke nipple hole and...

    New here and in this field. NEED HELP!!

    Why don't you reverse engineer some of the military UAV's out there? The Heron TP UAV is a design that can easily be replicated and individually stylized to suite your needs. That will basically give you a TON of options for payload capability if you use a large wingspan and big fuselage, and...

    The 'What did you do in your workshop tonight?' thread

    Depends on the generator, but most generators assuredly output more than 12 volts ;) The Predator 2000w unit from Harbor Freight is a good solid unit that a lot have been using, I liked the one I had purchased when I was with Hitec. 1800 running watts, the one at our club doesn't have an issue...

    The 'What did you do in your workshop tonight?' thread

    Well it's been al ong time since I posted, but I thought I should chime in. Doinked my AJ Aircraft 115" Laser 230Z in about 6 months ago. Broken prop, wingtip, pulled LG block, bent axle, and busted wheel pants were the extend of the damage. I already procured a new set of wings, and just this...
