- Freewing F 22 Raptor Build Part 2. Benefits to Switching to LIHV 4s Batteries. This is supplemental part 2 video to the build video I did two years ago. I decided to change to LIHV batteries to complement the high powered X-Fly 64mm EDF in this build.
UPDATE 8/5/2024
Flew the F22 with the LIHV battery setup and on the second flight the 64mm XFLY EDF bearings went out or it fried. It didn't smell but it made a terrible sound in the air and the outrunner is difficult to spin by hand. I just replaced it with another 64mm XFLY EDF and will lower the timing back down to the default of 18 degrees from 30 degrees. I don't know if that is the problem or not. The XFLYS are already pushed with their high KV ratings so maybe the high timing and the high amps or rpm is too much for it. Or it was a motor with questionable bearings. I don't know.
At 18 degrees the peak amps is now down to 59 from 67 and the peak watts is down to 898 watts from 1067. Hopefully this will keep the new motor from being damaged.
Here is the link to my initial build video Part 1

Going to try and put a autopilot on a few of these and have them fly in automated formation 😂 i know it’s gonna need some ballast in the rear
If you cant be bothered with LiHV batteries or the SMC USA only brand as you live outside USA and this being an international forum and want even better performance from your 64mm and your 80A esc... just use a 5S 2200. Im at 5° not 30° and my thrust gains are about 40%. 75A and over 1500W. Quite a few brands do 5s. My personal recommendation is internationally available CNHL 2200 5s 70c for all my 64mm jets. 3.5min timer.
I see they sell the batteries on Ebay but I see only 6s not 5s lipos. Are you talking about CHNL 2200 6s 70c lipos?
Does you charger support the LiHV packs? If not, they charge to 2000 and the lower voltages similar to stock. I've got the same setup :) Fantastic plane, I'm on my 3rd one ;0) I finally took the gear off and do belly landings with it too. It took me a few years as well to fly mine. The last time I had messed with RC as a hobby was 1985 lol.
Good job btw, and the plane looks awesome.
@@cybersecuritydeclassified4793 Yup it supports all formats. 85? Old timer!
I flew it yesterday on the LIHV setup with full advanced timing set to the highest (30 degrees) and I fried the XFLY motor. Or the bearings went out. I think it may have been the bearing because it doesn't smell burnt. I'm putting in another XFLY 4s but this time I am going with the default timing of 18 degrees. The peak amps drop from 67.4 down to 59.4 and the peak watts down from 1067 to 878. Hopefully I won't fry the next motor.
@@RKIVIDS Nice! I've got the shaky hands right now. About to re-maiden (3rd) my 90mm F-22. The 64 however is my favorite so far. Easy to transport .
