This special offer is for those speed guys who want to go seriously fast.
I would be willing to make a few of those kits during the next months. This speed plane, I just call it “Speedy”, is the result of several years of testing. For good speed numbers I recommend the best .40 sized competition engines such as MB .40 FAI and Nelson .40 FAI.
235 mph have been clocked in the past with an old style MB .40 RIRE engine.
Because I am no model hobby business man the kit comes with the basics: polyester-glass composite fuselage + engine/pipe cowl, glass reinforced styro-foam/obeche wings, styro-foam/obeche elevator unit
span is 43.3"
This is one of the fastest prop driven R/C speed planes made so far.
Its little brother - set up for 2.5 cc speed engines and pictured below – would also be available. Speeds will come close to 190 mph if powered appropriately...

HI DS! That's a beautiful looking plane! At the price you are selling these for, you aren't going to get rich, because you obviously must have to spend considerable time to make each kit! I have decided that polyester resin is good enough for me too, if I had enough money I would do my layups with super glue!
Here's the .40 sized version of the plane shown exemplarily with the MVVS .40 GRRT engine (this one's highly modded HeHe ).
Spinner diameter should be 1.5".
I never tested before, but I strongly believe this speed plane would also feel comfortable with a modified JETT FIRE .40 to .50 sized engine (with unmuffled tuned pipe). Maybe combined with the Nelson .40 FAI tuned pipe.
I guess bob27s could make a reasonable recommendation on that issue...

hey.... i have no doubt one of the high-timed BSE-.50 FIRE engines would make that move right along Easy enough to set that up with the FAI pipe or even the marine pipe. Having the throttle would be very handy.
one might be able to convice him to build a rear rotor F1/FAI type engine. I know he has .50 ducted fan engine parts.
beautiful airplane btw !

The one Chris Callow flies, for instance.
Sounds like the RC speed record for piston engined planes is ripe for the picking - the current record is only 214 mph, set back in the 1970s. Someone just needs to go do it.

I’ve received several emails asking for the price of the MVVS GRRT or GFRT pylon engine. These engines are the best 6.5 cc high performance engine in terms of cost-performance ratio IMHO. True 26.000 rpms.
Last but not least I’d like to emphasize that the 220 mph + speed plane kit comes with these items:
- custom aluminum engine mount already fitted to the fuselage
- carbon fiber speed prop capable of rpms above 30K

I a curious on the carbon fiber prop you mentioned. I also have the same engine and looking for a prop I can directly bolt without modifying to run up on pipe.
That carbon fiber prop is a true .40 speed prop meaning it develops its best degree of efficiency above 220 mph in our special case. Consequently this prop only will perform well in combination with an airframe enabling at least 220 mph.
Equipped with that particular speed prop you will notice a heavily unloading engine after the first powerdive. The rpms will jump from let's say 23 K static to 27 or 28K (or more) in the air
- if the airframe allows that.
DD and similar constructions unfortunately do not support aerodynamics clean enough for a 220 mph+ speed environment.
In other words: The single components of airframe/engine/pipe/prop should generate a 'harmonizing' unit in terms of speed performance.

you know, i have a little PRACTICE with these planes. the MB40 will set you back "after the bank transfer fees" around 600.00 US. a good FAI air frame around the same. then you can come to sunny ft lauderdale fl and try out for the USA F3D PYLON TEAM.
