Guillows Lancer Electric Conversion Build Thread

I'll be watching this with interest. I had the same idea knocking around in my head for a long time too. The Lancer RC conversion has been done many times. It's a good choice because the cabin style fuselage has more room for electronics than the Javelin. Look at what I did to convert the Contest Commercial rubber power free flight to RC. The Contest Commercial is like a scaled up Javelin. The elevator doesn't have to be the full width of the horizontal stabilizer. A half elevator simplifies the control surface construction and keeps the tail lighter. You'll want to keep the amount of additional ballast needed for the CG to a bare minimum. I've flown a couple of airplanes with a 1/2 elevator and it doesn't affect the stability at all.

PS - You won't need to add the fuselage reinforcement for the rubber motor mounts. They're extra weight.

Jon, I never noticed the 1/2 elevator setup on your Contest Commercial build. The frame out looks great, and if it flies well the only downside is the OCD / anti-symmetry spasms it creates in my brain :p
I know! It makes your brain hurt. You think, "Well that's not right. It can't fly straight". There's no difference between a full and half elevator in flight on models like this. I tried it first on a "Trainer One". Sonuvagun, it works just fine with half a tail. o_O

Also, as another odd-ball way of creating control surfaces, I did some weird balsa sheet extensions on my re-Run RC conversion. It looks weird, but flies great :D
That is a very cool looking little motor glider. I have to get an ultra-light Rx/brick that'll work with my Flysky FS-i6 transmitter. I love those micro indoor RC airplanes.

I think this little number might work for a UMX sized FlySky setup (like this Lancer build, to not hijack the thread too far :D )

For little servos there are these but watch out for the wiring patterns - not all teeny linear servos use center positive wiring, might need to switch the wires around in the plugs before powering up.

And I have used this receiver before, but it requires a WLToys compatible transmitter module or a multi-mode transmitter like the Jumper. And it also requires a rebinding cycle every time it's powered on, which is sort of a pain.

I still have the remote and everything relating to the guts of my poor wrecked radian. So I'm just gonna use those. I'm still new into receivers and radios, and the only "real" radio I have is a flysky i6. Plus the board contains linear servos already. I appreciate the input though 😉

I kinda want to only have the outer polyhedral on the wings. But I'm not sure how this will affect its flight characteristics. Any thoughts on that?

I might buy a WLtoys airplane and fly it until it wrecks just for the guts like you did. The Flysky radios use AFHDS protocol same as WLtoys and apparently UMX as well.

It has been my experience that it helps when turning to reduce the angle of dihedral or polyhedral when converting from free flight to RC. Because you'll have a rudder to control direction you don't need or want as much stability from the wing angles. I think your idea of keeping the outer polyhedral will work.

I'm thinking some version of monokote.
Just a suggestion, but with that light framework, I recommend the Coverite 21st Century Microlite. It adds less weight, Lower heat to seal and looks great especially in the clear red, yellow, green and blue. Check out my post under this heading, 36" Dumas Ercoupe. Use balsarite on your framework before you cover it, will go a lot easier. Welcome to our addiction!

Thanks. I've been looking for a decent brand. Also, your work looks very nice. I hope your flights go well 👍
