Bazz Bomb (oz3156)
About this Plan
Bazz Bomb. Bazzbomb. A 3-1/2 in span single channel R/C aerobatic model, from Aeromodeller October 1964.
Quote: "37-1/2 in Wingspan Single Channel Radio Control Aerobatic Model. Bazz Bomb, by Basil Murley
ABOUT TWO YEARS ago the author decided that some serious reconsideration was required concerning the type of rudder-only R/C aircraft that was needed to eliminate those frustrating delays on the ground through damage or unsuitable weather. The result was Bazz Bomb, A highly manoeuvrable design was required to facilitate landing approaches and also for the sheer fun of being able to throw it around the sky.
On the basis that the undecarriage was merely a tripping-tip device, introducing extra weight and drag - it was eliminated from the project, a move that has not been regretted. Bazz Bomb will make a good landing on any soft surface from mown grass to a ploughed field without overturning or damaging the under-surface. Designed to have maximum longevity and crash resistance (the author does not like building aeroplanes!) - weight became a secondary consideration.
As the designer is a radio enthusiast first, and aeromodeller second, great attention was paid to the 'innards' - nothing less than 100 percent reliability was the aim, and so far this has been achieved as no failures have been experienced in over 3,000 flights spread over two years. Of many receivers of all types made and tested one was really outstanding - this was the UK (RCME June, 1961) adapted to relayless, it scored on all points: range, reliability, selectivity, freedom from inter-ference and swamping. Only drawback for some modellers may be the slightly more complex battery supply, but as large capacity batteries have been used, they were wired in and virtually forgotten for months.
It was felt that Buzz Bomb could not be flown with a compound escapement as they are usually a trifle slow in operation and in any case it will be found that after a turn, opposite rudder is required to straighten the model. With a sequential escapement it is there waiting for you - no thinking required about which is left or right! Therefore, the actuator used was the Elmic Conquest. This was given a thorough inspection to ensure that everything was functioning before and after installation, also that it would pull in when the rubber was fully wound when using only a 3 volt battery supply..."

Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsThe Bazz Bomb was a big part of my early years in aerobatics. Rolls and loops were possible with this 'bang bang' single ch model with a Cox TD 09 singing away up front ... bliss :)

I well remember watching these fly on Wanstead Flats back in the early sixties. I was just a teenager and was in awe as all I had was a free flight Veron Cardinal. Fond memories ...

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
