I must say Tony, taking a basket case as you have and transformed it into what you have now is remarkable. Your workmanship is outstanding and you will wind up with a great AC when you are finished. Your posts show what can be done to correct problems for people who buy unfinished projects ,which maybe have some quality build problems. Keep up the good work.

My E Racer has the full carbon legs with the Berkut lower talons on. I installed the lower talons because I pulled into my hanger a few years ago and my right main had about 15o of negative camber, the lower axle bolts were almost pulled through the leg caused from heat. I made my trunions from 1/4 in angle with self aligning 3/8 bearings.

Really shaping up nicely Tony. Be great to have another Berkut in the air, keep up the great restoration project.

I lucked out on my (ears) as you say, the builder let me exchange the ones I traded in for the ones that were on the A1D5 engine. Maybe Lynn has a reference sheet on what mounting brackets go with what engine /Air Frame combination, then find out exactly what brackets are on the mount the Girrls are making and go accordingly.

Jack

I made my mount on the E Racer for the 0540 C4B5 but the engine I purchased had some problems so I traded the 0540 C4B5 in for a 0540 A1D5 and guess what, the mounts were different and would not match the mount I made. All you have to do is change the mounting brackets on the engine, worked for me. These little problems will drive you crazy.

Lynn is absolutely correct about the wing. I would in no way give up the glide quality and safety of the canard wing, I have been in a Lancair with power pulled bach and they drop like a rock. I have seen 59 in mp at sea level (about 448 hp) and my best speed at 10k is 291 mph with a fixed pitch prop. 66/103 at 3000 rpm. Above 250 mph is very difficult to achieve without a larg increase in fuel burn. At 250 mph cruise, 2450 rpm, I burn 19.6 to 20.3. That gives me about 2.4 hr cruise before I will need fuel.

Most of my testing was done at 170 kts and above and all comparisons were a +10-11 kts from 170 kts T to 220 kts T. I did not find too many comparisons at the lower speeds but I did find some. From 150 ktsT to 170kts T were identical increases as the higher speeds, either with the 103 prop or the 113 prop. The 113 prop was 10 kts faster than the 103 prop at the same rpm. My 113 prop will give me a true airspeed of 200 - 202 kts at 2150 rpm. The reason I do not have many comparisons at the lower speds is that I usually clmb out at 150-160 kts ind at 3000 fpm with the 103 prop. I did a lot of research before I decided to go with the blended winglets. I know Mark says the winglet moved behind the leading edge reduces drag in comparison to the E racers flush wing to winglet, but I have never found any solid evidence on how much improvement moving the winglet back has as on the LE or Cozy. I do know that moving the winglet forward and blending the intersection is by far less drag than the winglet arrangement on theLE and Cozy. I do not recall the exact numbers in the improvement between the two designs but I recall about 30% improvement with the blended design. Dont quote me on that , its been a while since I went through the info. I will say that of all the modifications I have made and tried on the E Racer, this was by far the most significant. I would like to thank Mark for all his professional help on the proper and safe layup schedules for this modification, I would never had attemped this without his input. To answer your question on the trailing edge fences. If you fly your canard without lower winglets as the E Racer is designed, trailing edge fences will lower your landing speed by 10 kts. They work great, however they are unnecessary with the blended winglet. I flew without and with on the blended winglet and could not tell any

noticable difference. Low speed handling with the blended winglet is identical as the standard winglet.

I have been really busy getting my E Racer ready for the last race in Taylor TX this week end. I'll try to get all the photos together for you and Tony when I return. They are quite detailed and the process is no more difficult than the original winglet to wing junction, in my opinion it is easier, stronger and 10 kts faster.

I had the same throttle setup in my E Racer during high speed taxi testing and it failed (froze) on returning to my hanger, only in the idle position. Needless to say, it was trashed the next day and replaced with an aviation quality cable and system.

Shirl had that system on the proto type E Racer for many years.

I had a similar situation on my E Racer. There were spots of my spar caps just above the skin height, I left them and filled accordingly, did not take that much to correct.

James Redmond turned in I beleive 242-243 mph this year at the cup race. That about 210 kts in a 420 mile race, darn good for a 360 with a passenger.

What do you project the weight of the 20B with cooling and all accessories?

The vacuum bagging is the way to go, I dont know why more builders do not use it. Your progress is looking very good.

The E Racer canard is exactly the same as the LZ except for two changes. There is an added center core 17'' long to compensate for the wider fuselage and the shear web has 25% more bid added. Spar caps are rhe same according to my manual. The overall length of my canard is 147 inches not including the end tips. Hope this helps.

Jack

Rick is correct. The planform is the same as the long except the depth of the top and bottom spar caps. The E racer has more spar cap plys on top and bottom than the long EZ. The vne on the E Racer is 300 mph. I have not seen the plans on the Berkut so I cannot compare their layups. The Berkut vne is 350 mph. I believe the E Racer ailerons are also longer than the Long and the trailing edge is straight.

Try- mreracer@tabletoptelephone.com Not sure if Shirl is still making them but worth a try.

Peel ply also works good on wet micro to keep it from sagging.

One other thing you might do is run a fan on the parts you are working on directed at the exhaust fan, it will remove any fumes and sanding dust from reaching your face and also will help keep you cooler. This works great also when sanding under the strakes or bottom of the fuselage, blows all the dust away.

Looking good Rick, I went through that a few years ago. Have fun in Italy.

I put the wilhelmson NG6A kit on my E Racer and it made a world of difference, took all the sideplay out. Have had it in for 3 years now and still solid. Highly recomment the product.

Did you ever start your E Racer project? From the threads, I wasn't sure. I never had internet access until 1999. All my communication with the E racer was with Shirl and he flew first flight in 1996. Let me know if you are having a get together in your neck of the woods and I'll fly down.

Go to Shirl Dickey Secret Project - Go to the thread index and all the info is still there. It looks like it just went away in 2001. Let me know if I can be of any assistance. Jack Morrison - E Racer 113, flying with 300 + hrs. My email address is n345jm@comcast.net. Good luck

Looking great John. I also like your proposed paint scheme. Time sure goes by in a hurry when your having fun. Keep up the excellent web site, your expertise and knowledge is appreciated by all.

I tested the wastegate controller tonight on static runup and it worked as expected. I am hoping I will see about a 25% reduction in fuel burn at low cruise, 230 mph. That should increase my range considerably, testing at altitude will verify that. In regard to the foam post, I was just being concerned. If the 1.6 is good to go, go for it.
