Upside Variable

Pitch Prop System

Thank you for buying our revolutionary UPSIDEDOWN VP-Prop System! Experience a new dimension

in 3D performance. Assembly and installation is quite simple, but please read the instruction manual for

important safety notes and valuable hints to get the best results from your system. This unit can be

used with a variety of motors. We recommend using the German made motor (MAOUSDBLMOT) 33 g

1300KV motor for smaller airplanes around5-8oz.Forlarger models we recommend using the E-flite

Park 370 1360 KV (EFLM1205) up to 12 oz flying weight.

Prior to assembly we recommend identifying all individual

parts using the parts list. If you find any part to be not

acceptable for any reason or missing, please contact us

before you start.

1.1

Push the ring (part #2) onto part #1. Ensure that the

rounded sides of parts face each other and that the ring is

pushed all the way in. Secure the ring with a small amount

of 5-min Epoxy.The ring has to be exactly parralel to avoid

imbalance.

1. Assembly and setup:

1.1

use 5min-epoxy glue

Part # 2

Part # 1

1.2

Attach two ball bearings (2x5 mm) to each prop blade using the

supplied M2 x 12mm screw.

Attention: Don’t over tighten the screws. The ball bearings must

spin freely!

Insert the aluminum prop adapter (part #3) into the pitch

bridge and attach the blades as shown in the picture. Insert

the blade holder (part #4) und secure it with two M2 x 4mm

screws. Check for free movement of the mechanism. If

necessary, remove any flash and / or glue residues.

1.4 M1,5x6mm 1.4 17mm If you want to use an existing motor mount, you need to drill a 1.7 mm hole at a distance of 17mm away from the motor shaft. 1,5x4mm You can now attach the pitch lever to the motor mount. M2x4mm 1,7mm 1.5 The variable pitch prop unit is fastened to the motor shaft with one setscrew. The aluminum prop adapter needs to be positioned all the way towards the ball bearing of the motor (to prevent the motor shaft from moving during negative pitch phases).

2. Programming (Computer radio transmitter Set-Up): There are several possibilities to set up the mix of ESC (Electronic Speed Control) and variable pitch control. The following set-up describes the usage of a computer radio with a helicopter program: 2.1 Choose a helicopter set-up with a separate pitch servo and deactivate any pre-programmed mixing as “Revomix”. 2.2 Use two flight phases (Normal and Acro or Normal and Idle Up) where you can program two independent curves for throttle and pitch. 2.

3. System check. Select phase 1 and carefully open the throttle. The motor should accelerate as usual with a conventional prop set-up and provide positive thrust. Attention: For best performance it is recommended to measure the motor current and to adjust the maximum pitch setting to avoid exceeding battery / motor limits. To check phase 2, start your system in phase 1 and run it up to full throttle. Switching to phase 2 should not cause any changes.
