I will be building an L39 over the winter using my friend Jepe's Fast Foam techniques. I was able to buy an all white EPS version locally.
I weighed all the foam parts and they are a scant 27.4 ounces.

I thought I would add a photo showing the primer and sanding that has occured this past weekend. I flew all day sunday as the weather was fantastic.

I did a search and found a Urethane Acrylic primer called Stix. I had it tinted light Gray, so now the painting can begin.

I added the wire retainer to the ESC Hatch, servo boxes are complete.

I am very close to test flying the Raptor. Here are some photos I took this morning.
I put my Dremel® to good work with the router attachment and made the wheel well openings, Servo box openings, and slotted the ailerons for the control horns.

If anyone has a suggestion for a sprayable FOAM SAFE primer I would like to hear from you. My favorite K36 is solvent based and a NO NO for foam.

Hard to believe I started this project a year ago. Life gets in the way sometimes.
I have to catch up with photos but I have been working on the model recently.
I have run the wiring harness and wired up the fan.
I sprayed the first coat of gray acrylic inside the ducting and sanded the first coat too.

Well I finally started working on the the Raptor again last night.
I applied the fiberglass to the bottom of the stabs and the insides of the vertical fins.

I ordered and received my decals from Tailormade decals.
Ralf is great to work with and his product is top notch.

I glued in the pivot blocks for the Stabs and trimmed the base of the vertical fins.
Jepe re-profiles the fuselage aft section to bring the model back to more scale dimensions.
I'll post photos this weekend.

Been a while since I have posted. I have been moving my business and that is now behind me and we have settled in finally. Time to get the work bench clean and ready to continue the F22 build.

Guys I have been working at the Jet World Masters so I have had zero time to build for a week. Sorry for the delay.

I glassed the bottom of the wings last night. I'm using the glass cloth that Jepe sells and the HT2 epoxy resin system. This is the first time I have used the HT2 so I read the directions and mixed the components on a gram scale I bought at Harbor Freight for $10.00. I mixed a total of 14.8 grams of resin (10 of the resin and 4.8 of the hardener) this proved to be the perfect amount to do the bottom of both wing panels. The resin is water clear and very slow curing. Tonight I will do the top side of the wing panels and one side of the tail surfaces. Just to be clear I am doing the glass work prior to final assembly, that way I can fill and sand the individual components which makes them much easier to handle.
After I do the final assembly I will lay a 2 strips of glass of different widths across the wing to fuse joint to spread the load.

I spent the evening reshaping the flying surfaces. Simply mark the center line of surface with a Sharpie and block sand leading and trailing edges to a thinner section. I use an auto body rubber block one has 150 grit paper and the other 220. Make sure to check your work and keep your edges straight. The EPS foam sands easy but take your time. Keep the sand paper free of foam build-up and your surface will be very smooth when you are done.

Next I focused On the wings. Jepe cuts the wings back down to their scale plan form.
I reshaped the trailing edges and the tips, remember thin means fast. Then I drew the lines for cutting the hinge line. I will be creating a live hinge. I will first glue the very thin Fiber hinges (.15 mm) onto the top surface of the wing. Then I will glass the wing panels and then route out from the bottom the hinge gap.

I cut the flats on the stab linkage and fit shims to remove the end play. This was done on a mill to ensure the flat is in exactly the same position and angle on both. Next I will glue the linkage into the stab with slow drying epoxy and then add an end cap of 1/64th ply before glassing the stabs.

Had time to glue the hinges on with thirty minute epoxy. I also checked the nylon pivot boxes for stabs for the correct spacing of the stabs from the fuse when installed.

I have the F-22 sitting on the bench ready to build once I finish Carl's BVM Sabre.
I will use JePe's 8S fan and Eflight retracts. This is going to be a quick build as the flying season is here and I'm not ready!

I was able to attend Florida Jets and I had a great time too! I made over ten flights on my Electra. Of interest it took three cycles on each the packs to get the iR of the packs to where they were at the end of last season. I purposely made short flights and the charger indicated that I was under 10% of the rated capacity of the packs. However when the charge finished I had only discharged them about 60% of their rated capacity.

The EVF "2" looks very nice and I held the motor, very robust! They have gone back to a Carbon aft fairing and have shortened compared to the aft fairing on my EVF 5612.

The new "E" Bandit is well executed. The inlets were made deeper towards the C/L of the fuselage which added a nice character to the fuselage just ahead of the inlets.
If you were to see the "E" Bandit next a Bandit ARF you would be hard pressed to tell the difference unless you looked in the inlet. There is a lot of exciting happenings in the EDF world!

I have been talking with Bruce of Century Jet Models, they are working on a Hawker Hunter. I am supposed to visit his shop some time in April to size of the EDF situation.
Hopefully I'll have some good things to post soon after.

It is supposed to be 65 and sunny tomorrow so a trip to the "Field of Dreams" is planned for tomorrow. Carl Rich and I will make the short trip North that is if he gets a yard pass from Mama.

Till next time.

The first EDF I built was the JePe F-16. I first saw a photo of this model on the Aveox website while searching for a brushless motor for a heli. I had flown Glow ducted fans years ago but became tired of the mess and news. I spoke to my friend Jim Ryan and asked if he had heard of the man from Holland that goes by JePe, he knew very little.
A few months letter while looking through the ads in the back of RC Jet International I spied a very small add for JePe and the first email was sent! I did not recieve a response after a few weeks but my efforts were not to be daunted and I decided to call. I reached JePe and his english was poor at best but I was able to place my order. I knew then why he did not respond to my email. I was told it would take about 6 months to fill my order, and he would not take money until the order was ready to ship. As my 6 month wait was coming to an end I was starting to get impatient as I had hoped to receive an email from JePe by now.
I remember calling EAM that friday night. After looking at their web site and inquiring about the edf's they offered, I told the person I was talking to that I was waiting on a Jepe F16 but was interested in some of his offerings, I was told that I would never get the model from JePe! I sent an email that evening to JePe and Monday I received a response stating that my kit was just about ready for shipping and that I should wire the money.
Remember I really knew nothing about this kit or man but I was willing to take a chance and let me tell you I was not to be disappointed!



Model and fan details in my next posting.....................

After 8+ years in this forum I have decided to start building my blog. I plan to recap my history with electrics focusing on the years I have spent building and flying JePe Jet Models.
