Ty I read through this entire thread Monday and I remember reading where guyz were modifying the mount to be able to slide the motor further forward. Would that be an option to help you out?

That's what I'm doing during my build. Just shaving off those little white tabs so it slides up a bit more.

Scatcat has a pic of what I am talking about with the motor mount.

I have some CF strip on hand that I am going to use to reinforce my Swift the same way.

That is just about the same as mine, I didn't cut the lower tabs all the way off though.. I did leave about 1/4" for support. The way that mine is adjusted, using an Emax 2805 and wobbly prop saver, the tips of the prop are lined up with the elevon hinge line.

Thanks for the link regarding moving the motor forward. That would definitely help the balance issue. Hopefully I can fly it after work today with the lead weight and then decide whether to go with a larger battery, move the motor, or some combination. Only moving the motor forward enough to be even with the hinges is a good idea.

I just maidened my retro yellow Swift II and I’m very happy with “light build” that Gene and others have advocated. First of all, I got lucky and nailed the balance and initial reflex (up elevator trim) pre-flight. A couple of clicks left aileron were all it took to get level flight at half throttle. Vertical is limited only by my ability to maintain orientation and it’s plenty fast. It slows right down to a crawl and glides well.

I was a bit worried that the lighter build wouldn’t handle the wind, but it easily handled sustained 8 to 10 mph winds with gusts to 12 to 14. Downwind passes were a blast.

I’m running the following power system:
- HXM2730-1500 from Hobby City
- APC 7x5e prop
- Turginy 18 amp ESC (overkill, but adaptable to my needs!)
- Hobby City Flightmax 3s 800mah lipo

Here are some thoughts on the build that worked well for me:
- Used the stock plastic motor mount in conjunction with the motor’s firewall mount per Gene’s recommendation; drilled out the metal firewall mount’s flange, removed one of the 4 tabs and mounted backwards on the back of the plastic mount. This does a nice job of pulling the motor in, leaving just enough room for the 7 inch prop. I did NOT shave the plastic tabs to move the entire mount further forward.
- Extended battery hole lengthwise towards the rear of the plane to accommodate the battery; added small triangle of EPP to the very point of the wing to protect the battery.
- Protected servo arms with by cutting a cheap poker chip in half and gluing in place
- Used 5 min epoxy to glue wing halves and tips
- Sparingly used hot glue for everything else
- Used 3M Scotch Extreme Tape for leading edges, bottom reinforcement and to tape in ESC & receiver. This tape sticks nicely to the EPP.
- COG right at spec; probably around 182mm from the nose

BTW, the EPP triangle and poker chips did a nice job of protecting everything during one particularly awkward launch.

Thanks to all for sharing your build notes/ideas.

Impressive skills, thanks for posting that.

Of course I fly like that all the time (in my dreams).

Thanks for the report, Dave. Glad the notes and pictures helped. I still love my Swift. It did better than the judges at the E-fest pylon race!

I have 2 swift II's one I was building as a heavy swift and the other as a light swift. so far All I have flying is my heavy swift. I built it with a 400xt hobby lobby motor, common sense 3s 1250 lipo and a 20 amp suppo esc,3.5 mm bullets, and deans ultras. I flew it a few times successfully, and quite a few times unsuccessfully, I tried different cg settings along with tx programing but I just couldn't get it setup to where I was comfortable flying it, I decided it was probably too heavy with the big lipo and the lead in the tail needed to ballance it..........so I decided to completely rebuild it. I now have in my posession a 1300 kv and 1700 kv blue wonder (they were out of the 1500 kv version), I put the 1700 kv on it with 2mm bullets and jst conectors, common sense 10 amp esc, and i can run 3 different 2c lipos from 800 mah to 1000 mah, and I have a couple of 3s 800mah and 1000 mah lipos. removed the lead from the tail. It's now quite a bit lighter but is tail heavy on all of the lipos that I tested. once balanced I sure hope the new setup flies alot better!!

any suggestions on prop size I should use with the 1700 kv blue wonder on 2s??

Also during testing with the old setup I broke the engine mount (not where it is glued on the wing surface)almost every time I took it out because I was running a collet prop adaptor and if the prop touched the ground under power, the mount broke. would I be better off with a prop saver type mount?

Gene, I wish I knew you were at efest, I went as a spectator, but I would have brought it with me to let you fly it and kinda get the setup right for me......
