Funjet Fun !!!

[Crash Test Dummy]

DH,

Towers site says Mid November, however they didn't say what year in November!! Hey, I like you Stryker in your avatar, Looks just like one I did a while back, but i didn't do the center in yellow. Just the stripes on the wings. I love the Black and Yellow combo.

The question is; do i get a 16/15/3 mega or do i go with the 16/15/4 mega?

Is there a better brand out there besides mega that might do a better job?

[termite]

There are some better than Mega and a LOT that don't even compare!!!

Mega= Great bang for your buck:p

The great thing about the Funjet is the easy to change motor mount, the bad thing about the Funjet is the easy to change motor mount is so large.
I have run everything from a 400df to a 450th to HET 3w or HET 4w on 3 or 4 cells and even a 400xt with a 7x7 prop.
The large jet-like outlet just blocks a small prop somewhat.
The HET 4w or Mega 16/15/4 has performed best with a 6 inch prop, would also like to try a 16/15/5 with a larger prop on 4 cells just to see if the larger prop it would pull would show some advantage.
Also wanting to try a 16/25/3 on 4 cells with the largest prop it would pull, but that would probably require a heavy battery for any good flight time, decisions, decisions.

Like Randy said the Mega is a great motor, you can't go wrong with a Mega. I would get the 16-15-4 and run the tried and true 6X5.5 prop on 3S. Or you could upgrade to a 4S pack with a 5 inch to 5.5 inch prop to really heat things up.

Keep in mind that I haven't even see this plane in person so, it's hard to make a recommendation. My best guess is that a 16-15-4 would be good for this plane. Check here for Megas www.dynamoelectrics.com Randy [Dynamo owner] is good people and he knows E-Power systems, and he is a great resource, thanks Randy!!

Those numbers are closer to what i want to see. Do you think i can get away with a 25amp ESC?

[Crash Test Dummy]

DH,

With the winter temps you may be ok with the 25 Amp ESC. However I always run a beefy [10 to 20 AMPS over the motor rating just to be safe] ESC in all my planes. I have never had a ESC heat up and fail on me yet. Just make sure you have some air flow to the ESC and battery.

I checked the amp draw on my 16/15/4 using a 6x5.5 APC prop and a CC45 and showed 30 amps, this using a Craftsman ammeter. On 4 cells it drew 40 amps.
Maxamps 3000mah 15c batteries, 3 and 4 cell

I plugged some E-flite can motors into a motor calculator and found out that they dont do very well when used direct drive. Always seems to be exceeding the motors amp rating. Are there any can motors other than Mega that are around the magical 2000kv to run the small props on the Funjet? Mega motors are too expensive for me.

[Crash Test Dummy]

Sure, try a Little Screamers Park Jet motor. It is an outrunner that is 2800 KV and it is under 50 bucks.

It really makes my Micro Jet scream!!! Here is a video.........

The HET 4W is a 2200kv inrunner and they're 50 bucks including shipping, heavier than the LSPJ motor but will take more amps if you need to push it hard.

Was that test done with a static mount on a bench, because you will draw more amps if the plane isn't moving.

[Schlepp]

Yes that was a static test, how much amp draw would you get in the air?
Like CTD said, probably on the edge, better use throttle control or maybe a 6x4 for safety.

While waiting for my funjet to come in I browsed around the net and found a place claiming the following:

Funjet RR £160.00

Ready built with 2 x Nano-S servos, Himax 2825-2700 brushless motor, Speed control and prop - just requires reciever and 3 cell LiPo to go 130mph!


I wonder whether that Himax motor can really push the funjet that fast? Maybe on 4 cells but only 3? Seems pretty insane.

[DetroitHawk]

HMMMM.

[Schlepp]

If a Stryker C goes 80 with an 80mph pitch speed then why not 130 with a 130mph pitch speed ?
Going fast just got easier.

[Phoenex]

nevermind..........

[Moonwalker]

I did a little more searching and found a message from the Hitec guys in the US on their site which states as follows:

"The Fun Jet was tested with an on board telemetry system that clocked it at 100 mph with the recommended power system in straight and level flight. We don't have any hard data like this on the MJ so I can't comment on that."

[Crash Test Dummy]

Did they state what the recommended power system was? I should be able to get a radar gun for this weekend. I'll get some speeds on my MJ with the LSPJ motor.

Multiplex USA says:

BatteryPermax BL-480 5DESCBL-37 Servos2 HS-55 or 2 HS-65

They don't give the prop size but the British guys are saying for 130MPH:

FunJet Power Set £108.00

Himax HA2825-2700 brushless motor, 5 x 4.5"" APC prop, 3.2mm driver, BL37 speed controller (for 3 LiPo)

Kind of sucks that they discontinued the Microjet. I love flying it around my neighbourhood freaking out all onlookers. . . . I bet the Funjet will be easier to see though.

[Crash Test Dummy]

Thanks for the info Moonwalker. I bet my 2815-3000 KV Himax or my Mega 16-25-3 on 4S will be a blast on the FJ.

Randy, do you have an availability date from your supplier?

no doubt, i am sick of waiting already.

[Twizter68]

LHS said first week of December....

[Crash Test Dummy]

My LHS said he talked to his Rep and they said he should have them by the end of this month!! The LHS owner assured me that I get the 1st one he gets in stock. I've waited this long so I guess I can wait a couple of more weeks.
