I want to incorporate differential thrust on the P-38. Can anyone point me toward a good video or instructions on how to set this up on a Spektrum Dx8.
Thanks

Thanks, that helps a lot .. spot on.
Greatly appreciated.
missing crop marks on the leading edge of the wing I purchased the speed build kit for the P38 and its been an awesome experience thus far. I would say an easier build than the corsair. my question is ;
Was it just me or did others have the missing crop marks on the leading edge of the wing. I paid special attention to any crop marks on this kit after the corsair build. The only reference I found in the video was johns reference to "about 5 1/2 inches from the fuselage". Could anyone who has built the P38 already verify/measure this with their build.
Was this an oversight in the speed build kit or plans ? Are their revised plans that show this critical dimension when installing the booms as that will affect motor thrust angle.
Thanks

Finally any build where I can use Clear Gorilla tape in the build is way cool!

Yes, that’s an issue that all of who have built the P-38 have come across. I thought the sbk had the marks right but I guess not - the free plans definitly don’t have any marks. And the measurements John gives are NOT right in the build video. You’ll have to install the tail first then align the booms so they are the same distance from the fuse and don’t have a thrust angle. I’m goi to tag @SP0NZ and @Splinter189 to see if they can give a better answer.
Two more questions on this build. John refers to a power harness with Xt60 connectors and shows it at 2:24 in the build video I don't see that listed in the power pack c twin pack listed in the flite test store. I had spare escs matched from other eflite planes so did not order the power pack. I am also looking to source the CCW props which are not listed in the flite test site either
Any help would be much appreciated
thanks

I can say that the XT-60 wire harness does come in the Power Pack C Twin pack. Or can be purchased seperately here: https://store.flitetest.com/flite-test-xt60-power-yharness-flt-2075/p797115
As for props, they have HQ slow flyer props in CW and CCW:

https://store.flitetest.com/hq-prop-slow-flyer-prop-10x4.5-2-hq-p010110450/p694739
Or this set that looks like it includes two of each CW and CCW:

Well thats wonderful news. I searched for at least an hour this AM on flite test site and several others and could find them. parts are ordered This should help to contain my cabin fever. Spring is slow in coming here - snowed last night and melting as we speak
Thanks again
Thanks again
I'm working with @Splinter189 to get this resolved for you guys. I'll post a new version of the plans with the correction soon. Stay tuned. Thanks for your patience.
All, the plans for the Master Series P-38 have been updated to v1.1. The missing tail boom alignment marks on the wing panels have been added. Thanks @Splinter189 for providing me with the missing information.
Awesome!!
Yes the new plans show the missing tick marks on the leading edge. The magic measurement is 6.5 inches from the center edge where the left and right panel glue together. I was able to measure this even though the booms are mounted and the center fuselage is glued. I used a control wire mounted to a barbeque skewer cut to 6.5 inches.
the back trailing edge dimension at 7.5 inches is 4 mm off as noted previously. How do I know this - in order to mount the horizontal stabilizer you will need to widen out the booms towards the edge of the wings by 4 mm.
other than that the build has been amazing. Making foam bend far beyond what I thought possible. Alignment is much easier to measure then with the bent wing corsair.

Seems like for whatever reason this video is impossible to find. Not sure about a kit but i followed this to make mine.

Still can’t find the actual kit with the plywood pieces

Yeah I just approximated these pieces. For the forward gear you can basically just trace the former. If you would like I can post the stls i used since i printed mine.
