I did use 300mAh 2S ... and I'm quite sure that you can fit also the 460mAh .. just push it as back as possible ...

Anyhow ... more heavy you get your bird ... and less pleasure will be to fly it ..

Outside it fly perfectly ... it is inside that can be challenging ... it is not very slow ... ... (or maybe it is just me that I can't fly slow )

Would the micro stryker brick be a good candidate for a transplant as i have a couple lying around.

In case you are still looking for tx settings, I use an old JR XP9303 TX and my D/R settings for the RadJet 420 are elevator low rate 35% and high rate 50%; aileron low rate 45% and high rate 75%.


btw, I wanted to share with everyone that the Turnigy B1230-4100 motor started stuttering after about 20 flights of running on the 3S setup. No surprise given that I was really pushing the motor well beyond its rated limits. This is the same stuttering that the AP05 in my Critical Mass started doing after running on 3S setup for 8 flights. The good news is that all 3 of my Plush 6A ESCs still work great, and never had a problem with 3S setups so far. I ordered one of those new BL1230-4200kv motors from HK to see if it will survive 3S using a less aggressive prop such as the GWS 2510.
I have this motor NTM Prop Drive 13-12 2600KV / 42W
And put the esc on high eff.
Then you get more power on 3S because the 2600kv is lower then the 3000kv from AP05.
My radjet flies still very good after 30 flights without smoke the motor.

Maybe helps this late post!

Keep to the 2s 180mAh as this little model flies best when kept light. I've even removed the decals off the lower surfaces to save a few Grammes in weight. The endurance is long enough with the recommended battery without having the penalty of extra weight.

OH BOY!!!!!! I finally ordered a 420! been drooling over it ever since it came out. I went ahead and ordered an extra body "kit" to go with it. I ordered the recommended 2cell 180's, and one 3cell 180 to fly with. have any of you noticed those new turnigy micro motors they've recently came out with? they look very nice, and their specs say they can handle 3-4 cell batteries? I don't plan to run the 420 on 4cell, but those motors look really nice.

my multiplex funjet is without a doubt my favorite airplane!! ive had 2 original funjets, 1 funjet ultra, and 4 flyjet x-830's. funjet ultra was heavy & didn't fly as well as the original funjet, so I sold it. but it is my favorite, and im looking forward to this one. ill be able to carry it pretty much everywhere. and fly it just about anywhere.
