Title: Classic Russian Stunter - Klemenow's 'Davidan'
Post by: Kevin Wright on November 21, 2012, 11:28:39 PM
Hi,
I'm trying to locate a copy of a plan for A Klemenow's stunter of 1967 vintage.
The aircraft is shown on page 113 of the PAMPA Classics Design book from
a small line drawing produced in the October 1967 Aeromodeller. A near
identical model was produced by the Spanish Modelhob company and called
Davidan.

See accompanying scan and photo's from http://www.miliamperios.com/foro/vuelo-circular-f29/por-fin-t199560.html
Regards,
Kevin

   Kinda looks like a cross between a Space Hound and a squared off Shark.  Some of the Euro designs from back then were pretty cool!
   HAPPY THANKSGIVING!!!!

Hi Kevin,

I would check the metric measurements against the kit plans and see how close it is to the Aeromodeler drawing.  The kit plans may be all you can get.

If you email Yuryi Yatsenko, he may be able to help.

HAPPY THANKSGIVING!

I took a close look at the published, small, drawing, that is posted on top of the photos, and the full sized set,from the Spanish company, called the Davidian.

It seems obvious that the Davidian is based on, and is a close relative, but, , there are deference's that barring a full, original plan set, or a set of measurements taken from the real original design, that I would have to voice concerns if a plane built from the Davidian plans were presented as Klemenow's classic design.

By your post, I believe you already aware of what I am talking about. Please take no offense, as none is intended by my remarks.

A very thin, and poor looking airfoil is shown on the Aeromodelor drawing. it is shown to be very thin at the tips. The Davidian has a good looking much thicker airfoil, and though it also would appear to taper at the tips, it's more like a modern stunter.

The other problem is with the fuse starting at mid chord under the fuselage, rib cut out. It appears that Klemenow's fuselage, under the wing, does not have the starved Guppy look of the Dravidian's fuselage.

When was the Davidian kitted, or published It would b e the better one to build without a reliable, rib set from the Russian design.

Thanks for the reply's folks.

I suspect that unless I can get a set of plans 'authorised' by Klemenow, both the Aeromodeller and Modelhob plans
must be deemed suspect.

Worst case, I'll take the styling from the Aeromodeller plan, moments and airfoils from Ted Fancher's Imitation
and jump into Turbocad.

It wont be Classic legal but it will look nice!

Regards,
Kevin

It's very similar in style to Sirotkin's 1969 Russian Nats model, except his had an elliptical wing.
This had 2 wheels in-line with wire out-riggers.
The red one was made by Chris Padham in the US. (Over 10 years ago).

Saw this one at the VSC a few years ago.  Forgot the modeler's name.

Haven't seen him in a few years, but I'm thinking that the guy shown above at VSC in Allen's pictures is Igor Panchenko.  Contacting him might be a good idea, and he's a member here. Look under "I" for Igor. Another thought, maybe Steve Yampolsky could help on finding info on Klemenow's model?

Don't forget that those were the days of the Soviet Union. Some of those guys on the teams were definitely not "Russian". I believe the brothers Yatsenko and Igor Panchenko are Ukrainians, anyway.

I have some doubts as to the trustworthyness of the small 3 view, but if it's right and there is one main wheel, the Davidan plan clearly shows two main wheels, a problem. Though the Classic rules in Oz are probably different than ours here in the USA, the Davidan would be legal (enough) for Classic here if you simply proclaimed it to be the Klemenow design, since there is no rule that allows DQ.  H^^ Steve

FWIW: Igor flew at the GSSC in Oct. There is a picture of his beautiful plane in the"GSSC" results report.

Klemenow and Sirotkin have been mentioned before, as having experimented with mono or tandem wheel designs. Sirotkin also had one with a more angular wing (1966, I believe):

Folks,
Thanks for all the replies.

I've sent an e-mail to the owners of the historical Modelhob website requesting any information they may have on the Davidan - no reply as yet.

I'll also follow up with your suggested Russian contacts,
Rgds,
Kevin
