No Sir,
I do not believe that you are trying to fight me. I believe that you are just trying to verify (from your perspective) what the video claims. I also believe that if you now go to that link, you will see the real-time timeline that happened after I read your comment from U-TUBE.

NICEwebpage you got there !!!!!!!

I am not too sure. You see, that video was supposed to be for the zip start launch. I dont remember which motor/prop/battery it was as I flew a whole bunch and got them on video. Stroke of luck it went over 150, thought it was more like 140 while I was flying. I guess I need to re-calibrate my internal speedometer.

Anyway, I will get another video that is set-up better within a few weeks. I am a little occupied right now with a few other projects.

ya back to the funjets
I have good news I got my move done and a new shop set up. I all most got my molds done for my carbon fiber funjet hopefully late summer I'll have the first on done and flying

Gryphon

theb1bman ,

Please clarify about the molds for Carbon Fiber Funjet . Sounds interesting.

Congrats on finishing a move...I never look forward to those.

about 6 mouths I had posted the starting of it. Heres some pic of what I had post here. I will post more of it as I get it done tomorrow I'll be down at the shop and take some new ones.
I'll keep them comeing

hello everyone! Since i am going to be entering into the funjet craze i was wondering what setupi should use to get my plane flying (what servos, esc, motor battery ect...). Im really looking to get long flight times as i am going to use the plane for FPV. any suggestions will be greatly helpful in my final decision.

Hi theb1bman I like the Idea of a carbon FJ ,what are you using to cast the mold with is that plaster or a rubber/silicone product. Will you be making a plug first using the mold in the pic's in order to make a more detailed production mold? Blanik213

theb1bman

blanik213

theb1bman if this works out to the best of your expectations you are going to be making alot of FJ's,Good luck with this project .I am concidering making a mold of my modified TJ but I will first make a number of test flights to check that the mods are sufficent and on target then mod another one that I will make the mold of.

theb1bman

TJ ? tam jet

blanik213

Twin Jet that almost forgotten plane .The Fun Jet is the new version of the TJ with improved airframe less drag and cheaper to go fast with only one of everthing but I believe with the right mods the TJ can be very fast and easer to see at lets say "160+" and yes manny will say that will never happen, I think other wise.Here are a few pics you might find interesting the build threads on rcgroups under pusher prop jets/twin jet build tips and talk I know this is a funjet thread but the mods I've done can be done on the fun jet or any foamy for that matter.

theb1bman

da I sould of known that!!!!!!!! I did have one of those and wish I still did
I think you should turn it into a plug mold they dont make that one any more for what I heard
I do still have a couple mico jet that I will mold after the funjet is done and flying

If you want some good Ideas on mold makeing out of fiber glass have a look at this guys videos I will be doing them that way from now onhttp://www.youtube.com/user/hornitpilotthere are 33 videos of how to plus the plane is bad - it's a 20 footlong B1B with 4 45 pound thrust jets man it is sweet I have a video dose not show as mush as his. It's on my youtube page look for The Birth Of a B1B http://www.youtube.com/user/b1bman

is this too big a battery pack to use for a fj?
Great Planes ElectriFly LiPo 11.1V 3350mAh 25C Power Sr

gotboostedvr6

It will fit but you can pick much higher quality lipos for half the price..

panzertank

could you give a reccomendation as to what battery i should get? im using this http://www3.towerhobbies.com/cgi-bin...?&I=LXPVK6&P=7for a motor and esc.

theb1bman

I would not go over a 2500 a 3300 is to big and heavy
It will fly real nice on a 30c 2200 pack

Gryphon

theb1bman ,

You do great work. I am very impressed.

Looks like you may be able make a DREAM Funjet airframe.

_____________________

On the high side of battery packs, the following have been previously used in Funjets by various people:
4S-5000, 5S-3700, 6S-3300
5S-3850 and 5S-5000 are in the works too.

No doubt low speed flying capabilities go out the window and launching them takes some practice.
But that is how 160-175+MPHcan be achieved.

My new Custom MEGA16/35/1.5 was tested to near 2500W on 5S-5000, I am 100% sure it can lay down above 175 MPHpasses even though it is 28mm motor, 56.5mm long, 160 grams, 5mm shaft.<o></o>

500W per cell….yes<o></o>

Below is screen shot of APC Pylon 6.5X6.5 on TP 4S-5000 30C at 25% discharged pack (ground testing).

Other pic shows the custom motor next to regular 480 sized 110 gram MEGA16/25/2 2650KV3.2mm shaft.

Note: Given Funjet’s limited cooling airflow to the motor, there would have to be some throttle management.

My Feedback: (121)

Hi guys,

I've read pretty much this entire thread. Good stuff. I used to chat with Gryphon and CP on the Stryker threads. I wore out my Stryker and got into a 50CC electric Extra for a while. 2 6S 5000 packs at a 100 amps is some juice

Anyways, here is what I have left over from my Stryker. What would this do in a Funjet?

Mega 16/25/3
CC 45
4S 2200 packs
HS 82 MG servos

In my Stryker I think I remember getting about 95 mph at 40ish amps on a 7x7 apc. The verticle was great and overall flying was enjoyable. For that speed range I liked the low amps and thrust. I thought about building another but want to try something different.

I also previously ran an HET 2w-25 on a 6x4 but the amps were way higher. The speed was a little better and the verticle was awesome but it was crying out for larger packs.

Are my Mega and servos to heavy for the Funjet? I would like decent flying with a top speed of 110 to 120 mph. I could sell the mega and go to a higher kv if needed but I don't want to waste money if I don't have to. If I wanted to do 170 I would just buy a ducted fan jet.

I am also looking for the mods I would have to do to fly in this speed range.

Thx

Rino

Hey all, I've been messing around with homebuilt combat wings with my brother, but am getting back into high speed stuff again. Finally got my FJ back flying again! Wanted to say hi to you all, missed you guys!
