Indoor Competition Rules

BMFA Pussycat 2026

The rules will include three duration and three precision flights however you may build and use two Pussycat models (one with trike undercarriage and the other with tail dragger two wheel version).

A single motor must be used in each version for all competition flights.

It is not essential to build two models if you prefer to use a single model for all your competition flights — however a tip from the Norwind indoor group is the trike undercarriage version is better for precision flights while the two wheel version comes out top for duration flights.

The times of the precision flights will be provided on the day of the competition.

If you wish to be in front of the game Brian Lever has plans and full building instructions for the Pussycat (which is a great indoor flyer in either configuration).

If you send your full address details to Brian at [email protected] he will send you a plan free of charge and you can commence building to be ready for the first Bushfield Indoor competition on the 17th October 2026.

As usual there will be cash prizes for the overall winners and laminated certificates for 1st, 2nd and 3rd places at each individual meeting.

Hangar Rat

The competition is for the ever popular and superb flying Hangar Rat.

This came about when BML was talking to the Chairman of the Nottingham club, Richard Granger and Richard mentioned that they run a Hangar Rat competition at their Indoor meetings. Brian thought this a splendid idea and put it forward. I too thought it a splendid idea and agreed.

So.......The Rules.......as Andy Sephton reminds us...First. READ THE RULES...... here they are. (Richard, forgive me for pinching your rules, but they are so good, it seemed unchivalrous not to use them.) If I have got any wrong, I apologise beforehand and I promise I will fix and announce the corrected versions immediately.

THE RULES

  • It is a standard size Hangar Rat, built to the plan.
  • It will be paper (tissue) covered, no films allowed. (I assume this can include condenser tissue?)
  • It will use a commercially available plastic propeller. (further clarification below.)
  • It will be rubber powered. (just in case you thought you'd get away with it Ian)

All scoring flights will R.O.G. (This is a must…hand launched models will score ZERO) The undercarriage will be exactly as per plan…this includes the wheels (no exceptions, there will be a height gauged check on the high scoring models.)

There is no weight limit on the rubber.

It may be balanced by adding weight to the light blade.

It may have the hole for the propeller bushed with suitable tube with a view to re-aligning the shaft hole. (so it's straight)

Flashing on the blade edges may be removed, but no sanding of the blades allowed. Balance is by adding weight. Now, you will notice that there is no weight or size limit to the propeller. This allows the flyer to make the best choice for his or her model, and the diameter will be governed by the need for the model to ROG. (this also excludes thin floppy lightweight guitar string U/C's, they will have to be strong enough to support the model as it ROG's) No Bamboo u/c's either… as…per…plan.

No limit to the number of flights.

Plans & Instructions

Both A Rat and B Rat plans print out full size, 2 pages each — join with clear tape. Choose one, or both.

Bernie's Gyminie Cricket Rules: Regular and Unlimited

Regular:
Models to be built as per plan including the use of the propeller/nose bearing assembly: tissue covered with a minimum weight of 9 grams excluding rubber motor. Models will be weighed, and ballast may be used. The prop must be the one supplied with the kit & can be balanced by adding weight to the lighter blade. (I will get a supply of prop assemblies, at 40p each.) The rubber motor is at the flyer's discretion, using as much or as little as you wish. The only exceptions I will allow are: a piano wire prop shaft, as the original bends too easily. You may choose to bush the nose bearing. Also, a better rear hook may be substituted.

Unlimited:
The model must conform to the plan outline (i.e. no big tailplanes.) And that's it! Everything else is allowable. Wing posts instead of a sheet pylon. The best indoor prop assembly that you can make, curved ribs, film covering, condenser tissue if you prefer & the best wood you can find. No weight limit. As an example, I made one that weighed a fraction under 3 grams, which did 1m 57sec under the eight foot ceiling at Peakirk, and nearly four minutes at Oundle. Should folk be interested in trying this class I will do a building demo at Peakirk to give some ideas to use as a starting point. My best one used a prop based on a plastic yoghurt carton and guitar string shaft — it's much easier to do than it might seem. Easier than an EZB, for instance. Contests to take place at Bushfield, dates to be announced.
