brand new 5-cylinder Penta 52 from Calibur-Moteurs

On ModelFlight #15 we saw a nice collection of models belonging to a group of visitors who had visited Bob Nicol's club, High Peak Model Aero Club, UK. There was one other interesting item which they brought with them and that I said would 5_cylinder_engine.jpg (16329 bytes)be shown on this update, and it is this superb 5-cylinder engine that was hand-built by one of the visitors from Holland. This beautiful and very compact  engine was developed by Dick van der  Veldt to fit into any 1:6 scale model. Dick - a highly-skilled model pilot - used all his expertise to make this state-of-the-art engine. The prototype passed an extensive test programme with great success. A few minor modifications have been made to optimize performance and series production will start with the Mark II version.

The technical specification of the prototype is as follows:

  • 220 mm diameter
  • 145 mm inboard length
  • 23·4 mm bore
  • 24·0 mm stroke
  • 51·6 cc
  • 3 HP
  • 2650 grams
  • Operates at 1500 - 7000 rpm
  • Runs 7000 rpm with a Menz prop 20x8 or 18x12
  • Separate oil chamber for valve distribution
  • Complete with exhaust ring

 The Mark II series will have a 24 mm bore, resulting in an exact 'square' engine of 54·3 cc.

Currently, Calibur_Moteurs does not have an Internet site of its own, but is in process of going online in the near future. If you are interested in purchasing this engine, you can contact Calibur-Moteurs by fax or phone:

a trip of a lifetime for Steven and Joanne

A few weeks ago, Steve Bolin had what he has described as 'a thrill of a lifetime' when he and his wife "First Lady" Joanne had a flight in this restored B-17 WWII bomber, "909". The trip will have had an added interest for Steven as he is building a large-scale B-17 - a project we are following on ModelFlight. 

The B-17, together with a B-24, flew into Bellingham International near Steve's home town of Kent, Washington, USA on a touring schedule, which they seem to do on an annual basis. The planes, owned and operated by The Collings Foundation, are on tour for ten and a half months out of the year and all donations arising from the trips go to support the aircraft.

Steve and Joanne's flight lasted for about an hour whilst they flew over Puget Sound and the city of Seattle. Steven says, "It was a thrill of a life time. All this while the sun was setting too. Magnificent!"

The aircraft takes eight passengers at a time plus three crew. Steve says that sitting in the glass nose was truly an experience to be had. There was also a section on the top that was removed, so passengers could stick their head out into the slip stream to take their photographs.

B17-3.jpg (16717 bytes)This shot was taken in the nose of the B-17 - Joanne's head just in view and Puget Sound not more than 100 feet below. Access to the nose was gained by crawling down between the pilot and co-pilot! Steven says, "The sight of the Puget Sound at dusk . . . with people running out of their houses to stare up and wave as we flew overhead was overwhelming! You could see their faces."

B17-4.jpg (10877 bytes)Steven stuck the camera out the top here. Mount Rainier, dormant for a while now, can be seen on the horizon. Steve got so excited, he didn't think to retain the camera strap which flapped across his field of view as he pressed the shutter - hence the bit of rough touching up to get rid of it! 

B17-2.jpg (32080 bytes)The section in which these two are standing is where the radio operator would normally reside. The top had been removed for viewing pleasure and it was also where Steven sat for take-off and landing.

 

And finally, this moody shot taken shortly after take-off at 8.13 p.m.

Biography of "909"

After hostilities ceased, the original 909 with its 600 holes flew back to the States and succumbed to the scrapper's guillotine. She had successfully completed no less than 140 combat missions.

The B-17G 44-83575, now restored as "909", was built in Long Beach, California and commissioned April 5th, 1945. Too late for war service, 575 did serve with Air/Sea 1st Rescue Squadron and later with the Military Air Transport Service.

April of 1952, 575 was subjected to 3 different nuclear explosions with instrumentation on board to measure effects. After a 13-year cool-down period, 575 was sold as part of an 800-ton scrap pile, and Aircraft Specialties Company began restoration.

For the next twenty years the plane served as a fire bomber and was then sold in January 1986. Restored by Tom Reilly Vintage Aircraft back to her wartime configuration and renamed "909", she represented one of the finest B-17 restorations, having won several awards. Then, in August 1987, 575 - now 909 - was caught by a severe crosswind after touchdown. Crashing through a chain link fence, she sheared off a power pole and roared down a 100-foot ravine. No fatalities, but the aircraft sustained major damage.

Landing gear was sheared off and the chin turret was pushed into the nose. The plexiglass nose was shattered and bomb bay doors, fuselage, ball turret, wing and nacelles all took a tremendous beating. Engines and their props were torn from their mounts as well.

Again, this B-17 has arisen from the ashes. With nacelles from the "Shoo Shoo Baby", thousands of volunteer hours, support from the folks of Beaver Falls and donations from individuals and corporations, she flies yet again! She requires $2000 an hour to operate.

My thanks to Steven for details and photographs of his trip and biographical information and acknowledgements to The Collings Foundation.
