Well, it's been almost 10 years since I made any progress on the 109 but I'm slowly get back in the saddle. I apologize to anyone who may have been following this build but I had some life changes which created a slight detour. It seems though that I left you in good hands as I've seen some great looking 109's here.

I left off with graphics and now I have in hand nomenclature graphics from Callie. I'm still working on another couple of projects but I hope to get back to work with the graphics in the next month or so.

Wow...talk about a blast from the past. Don't feel bad...I haven't built or flown a plane of any type in well over a decade. My Taylor 109 short kit has never even been laid out on the workbench and I've probably had it for 15 years.

Haha! That's funny. I know it has been a while and I debated whether to even continue the thread but in the end I want to finish what I started even if it is rather anti-climactic.

Always learn so much from your builds.

Thanks Clive! I only have the graphics left to do to finish it up but it will be my first time with these graphics so I'll be learning myself as I go.

My apologies once again. I don’t post much on RCU anymore because I find posting photos to be a little tedious. Anyway the model is pretty much up to maiden status, I had paint issues that had to be dealt with but unfortunately I couldn’t get the paint match that I needed when I repainted.

Here is what was done to complete the model. Go to the top. I gave up trying to post the photos within the post.

”Birdy” was painted.

And where she stands now.

Thanks for the kind remarks Greg, limodune and planekrazee.

I had wanted to use a RCV90SP for this model but after trying it in a Seagull 109, there just didn't seem to be enough power so I am considering changing to a Saito 125. Right now I'm a little on the fence about this and will wait for the Saito to arrive to see how it fits within the cowl before really making the decision.

The Saito 125 arrived and I did a quick prelim check to get an idea of cowl modifications and it was obvious that too much of the cowl would have to be removed for the engine to fit. So, I’ve decided to go ahead with the RCV for the initial flights and if I find the power to be unsatisfactory then I’ll make the engine change.

The RCV has been reinstalled in the model and a shake-down test with the engine and airframe was conducted. Found a few items that needed attention including a couple of loose cockpit pieces and some engine problems because of a new carb and intake manifold. Did another run today after some work on the carb and the engine is running better but not quite there yet. With any luck, the engine will be running well tomorrow. This photo was before the first test run.

Have spent quite a bit of time dealing with engine issues. I've had to rotate the cylinder 90 degrees in an effort to cure a sag as the engine decels from full power to idle. Still working this issue.

In the meantime, a Vanessa rig was built and I have been playing with it some with the 109. With 99% of the model assembled, she weighs in at 11 lbs (5 kg) and, in its current state, the cg sits 4.5" from the leading edge with the horizontal stab sitting level.

Finally got the engine problem sorted...it was a new carb that I had installed but is defective somehow so the original was reinstalled and engine runs great now. However a new problem has arisen with glue joints coming unglued after 10+ years. First, the throttle servo mount broke free from the balsa slab base and then today, while running the RCV, the left aileron hinge broke free and the flap mounting nut came loose.

Repairs to the aileron and flap hinging have commenced. The aileron hinge will just require a re-glue while the head of the flap hinging bolt pulled through the hinge hole so a washer has been added to prevent this in the future. The other wing half will have to be checked as well.

The problems that have arisen from the engine vibration have led me to the decision to replace the engine with an electric motor. I have no experience nor knowledge of electric motors so I am soliciting advice as to the proper combination of prop/motor/battery for this 11lb (5kg) model.

Cut a new aileron hinge, installed and painted it.



Have decided on the Eflite Power 90 motor using 6s 5000mah battery and probably an APC 18x12 prop. To prepare, the glow power accoutrements were removed and the some of the holes plugged.



The original firewall was removed and a new one was fabbed by laminating 1/8" balsa with 1/16" ply. Longer side wall supports were glued in account for the shorter electric motor and then the firewall was glued in using 3mm foamboard acting as the spinner backplate (will have to enlarge aluminum backplate to accept prop shaft and don't want to do that until happy with the P90).



Then, the tedious process of separating the lower half of the cowl from the upper to facilitate battery access was done using a razor saw and back of an exacto knife blade.





A half former added to front for support. Cowl will be attached using tongue-in-slot in the fore and magnets in the rear.

Hi looking for a bit of help,A friend of mine has a mold for the fuse of a bf 109e, We think its off a Brian Taylor 68",Can someone measure the chord of the wing from the edge of the fuse. If we get a match we can buy a set of plans,and make a couple. cheers Al

I came up with 15 3/4” but the trailing edge fairing makes this a little arbitrary because of the curvature. Still, it’s as close to the fuse as I could get.

The tongue-in-slot wouldn't work due to the wing getting in the way of the cowl moving fore/aft, so went with plan B of using 4 sets of magnets.

Lower cowl attached with the 8 total magnets in place.

Cleaned up the areas that had been damaged earlier. Did manage to get the fuel dot out with no damage and filled in the hole with my usual ca/baking soda.

At this point, the model is flyable. The spinner still needs to be addressed but I would like to try my hand at a homemade spinner that I've seen a few modelers create but that may take a while. If a good day presents itself, I will try to fly the model as is. Clean-up will include touching up the repaired areas on the cowl and I may add just a little to the exhaust staining to give more depth.

The last major effort to be completed was the weight/balance. Initially, a 6s 5200mah LiPo was strapped in and the cg came in about 1/2" behind the balance point shown on the plans of 3 7/8" from the leading edge. It took 276g (9.7oz or .6lb) to balance. So, a 6s 6000mah battery was swapped in and everything (battery, esc and 6v NiMH rx battery) was shoved as far forward as possible. Even so, 98g (3.5oz or .2lb) was required to balance. Once the spinner is completed the additional lead weight will probably be removed. The lead bar can be seen zip tied on the bottom front of the firewall below the motor. Total weight of 12 pounds (5443g)...a far cry from Brian Taylor's 10.5 lbs of his prototype. Now considering a 7s 5000mah battery which is close in weight to the 6s 6000mah.

The lower cowling flap was attached last. I wanted this to be movable to reduce the chances of it being broken off if it were rigidly mounted. It was attached using 1mm brass tube and an old guitar string. The string made it possible to conform to the curvature of the cowl. Both the tube and wire were bombed with thick ca. It appears robust enough at this point and I don't believe that wind blast will be strong enough to pull it off.

The lower cowl repaired area was touched up with Tamiya Yellow and a drop of black. Weathering will help to blend this in with the rest.
