Jato Guinea?

[SEEBO]

I just got my FT Guinea SBK cause after building several of the more advanced kits like the Twin Otter and Legacy, I started getting an itch to REALLY test the limits of foam board models and what better plane than the Guinea Pig? As I type this I have shock absorbing landing gear and nacelles printing along with some other small bits to enhance the plane a bit. With the nearly endless possibilities of the Guinea I turned to youtube and the forums for ideas for airborne shenanigans, with a big one being Estes "jato" rocket assist. I was curious as to how folks have been able to ignite them remotely? I've seen some of David's smoke bomb devices but they seem to require a bit more electronics than I'm competent in. One of my experiments is going to be seeing how much weight I can take off with by both engine power alone and with Jato assist. Also plan to do some RC car drops and maybe some bomb drops as well as my own personal attempt at a water drop firefighting plane. So to reiterate after my ramblings... how do I remotely ignite some Estes rockets from a TX signal?

Don’t tell anyone that I told you this, but brushed esc’s…


just kidding you can tell 🤣

Why not? 😂

I used this method for my Bell X1. It is fired by using the gear switch(or any 2 position switch) so power is off until you flip the switch, then the servo arm moves down to complete the circuit.

1) Used only 1 cell of the 3 cell battery for powering the igniter thru the balancing plug.
2) Use a 2 position switch(used gear switch) and a channel to hook up the servo that is hot wired to the igniter so when switch is flipped the servo arm closes the circuit. One small metal clip is fasted to electrical wire and stationary on moving arm and other metal clip and electrical wire on fixed spot on airframe. Adjustment of pressure of 2 metal clips when closed is done by setting the end adjustment in the transmitter.

Use Estes' D12-0 with no parachute charge so doesn't melt your foam. Got 7 lbs max thrust. Have video.

What I mean is, is there something wrong with using a brushed ESC?

Oh no, just a joke about people hunting me out. (Wouldn’t really happen lol 😂)

Ah okay 😂

I need to MAKE estes-ish igniters for smoke bombs in the air.

FYI, inside all those broken servos you have is a brushed ESC......

Hmmmm...I have a few broken servos

 

[Houndpup Rc]

I wonder if it's powerful enough...

If you use the coated igniter, maybe. Last time I used one, they fired on a single "C" cell, your servo wiring is about 1/4 that even though it is higher voltage. Hmmm fire engine, plane catches fire after cooking radio equipment. What could go wrong?

Motor esc is better bet

Seperate BEC at a minimum...... Maybe heavier wires.

Couldn't you just isolate an igniter circuit with relay and it's own tiny battery?

i e used one of these with power from the balance plug. i tied it to the bind button because its the only momentary switch on my radio. press until it fires and then let go. that way if remnants of the igniter touch you don't get a short. also doesn't use receiver power for ignition.

You kinda want to isolate high power stuff from your flight control stuff. The motor on the plane uses the most power (in watts) but is designed to not interfere with the control systems via the ESC. Suck up too much power and your airborne radio should go into restart mode which takes a bit of time that you don't have low and slow.... Bad juju close to the ground to have servos full deflect then center. Worse juju to have the jato motor light off with the nose pointing down, unless you need a hole in the flying field full of slightly used airplane
