Hey Don.. My F-18 is on the way I want to use the wicked 6000kv and wemo micro. What size esc would I need ? Also would a 3s 1350mah 25c give me at least a three min flight time?

You want a 40 amp. Flight time will depend on throttle usage. A 1350 @25C = 33.75 amps This setup pulls about 32 amps so that is 23.7C which is 60/23.7= 2.53 at full throttle. I went to the 3S1800 20C packs

Hey, Don-

I ordered up the 6000kv motor and Wemo fan to install in this F-18.

It looks like your exhaust ducts are optimized for speed but would leaving the outlets alone allow for greater thrust? Would it be close to 1:1 with the battery you suggested?

I like the sounds of 85-90mph but I'm more interested in climbing power.

I have the motor, 40A esc, 1800/25c packs from Hobbypartz... now I just need the damn airframe!! It's shipping... just slowly, I guess.

Smokescreen38,

I've been flying my wicked powered f18 down here in Corpus Christi tx over the past couple days and I must say you won't be disappointed with the climbing ability. I have Dons 5400 wemo combo with the 30a pentium and I put a rhino 2250 in this lil jet and even with the extra weight of the battery it had unlimited vertical!!! The only difference I noticed flying this larger battery was the landing. With the smaller batts it flares very nice at the very end of the landing so it just plops onto the ground with no sliding, with the larger batt it won't flare so the landings are a lil hotter.

I also am building a balanced wicked combo with 6000kv motor. I will be using 40A esc and 1800mAh 3S. I am considering adding 2 more servos to have traditional ailerons and elevator.

I am not sure if the nozzle reduction on the bifurcated is a good thing. I was thinking of removing the thrust tubes I installed and fly it stock size to see how it goes. I would leave stock size for now.

Great to hear... thanks for the insight. I hope the 6000kv motor with 3s performs that well.

Landing issues are to be expected.

Thanks... that's what I'll do. I will report back on how the maiden goes but I won't have a reference point for comparison except for a stock 50mm Jpower F-86.

Remember to use those strakes on the F18. They make landing really nice. You get low to the ground then pull up elevator and those strakes will slow you way down. Try it a few times at altitude, if you do it too high you may stall out when landing (but I land with power off), it takes a little practice to get the timing right but works great.

I flew the F18 with no thrust tubes and I think it is better this way. It seemed to me just as fast and had more vertical. One thing I did notice when I removed the tubes was that the plastic nozzles extend into the ducting so I used my dremel and sanded that sharp lip off. So I say do not bother install the thrust tubes in this one, leave as is.

Hi Don,

I am thinking of ordering a motor/fan combo for this F18. I am not sure if I should go 4S or stay 3S. I want to try not to order new batteries, but I think my 3S batteries won't be enough to power the new motor. I have a few 1300mah 20C. That's only a maximum 26A draw. So, I figured if I'm going to order a motor I minds well go 4S if the batteries I already have won't work ha-ha. If it's too much of a pain to find batteries for the 4S set-up, I'll just go with the 3S 6000kv motor.

I am ordering a 40A volcano series ESC from nitroplanes soon, which seems to be the same one as the hobbywing one you recommend on your website.

Do you have any recommendations on 4S batteries that work in the F18 for the 4800kv wicked combo without cutting any foam? If I HAVE to cut foam I will though. Also, how fast is this set-up? Will it be pushing 90-100mph?

For 4S I would probably use the 4S1800 pack which is what I used in my 50mm F86 that is a nice pack but would have to double check the pack width to make sure it fit. I would think the F18 on that will be close to 100 mph. Honestly thought the 3S and Wicked 6000 is a blast in this F-18!

I think I'm going with the 6000kv! Thanks Don. Unfortunately, I went to order one this morning, about 10 minutes ago, and it say's it out of stock . Early worm gets the worm, ha-ha. When will you get more Wicked Wemo 6000kv Combos in stock?
