Review: Tobe's MaxiPelle GG

Post by Pchristy »

Not really sure what to post this under, but since the label on the front says "GG", I'll plump for here!

As many of you will know, I was fortunate enough to win Tobe's MaxiPelle GG outfit, which he offered as a sweepstake prize following Ponty this year. A nicely packaged box arrived from Sweden a few days later, but on opening it up I was absolutely gob-smacked! Not only did it contain the MaxiPelle GG outfit, but a selection of receivers and servos - indeed enough bits to build a complete additional system!

Posting this initial review got delayed a little, as being keen to get it up and running (alright, have a good play with it! :lol: ) I powered it up and examined it with the spectrum analyzer. This revealed that it was transmitting a bit out-of-band, so everything else got put on hold whilst this situation was remedied (see the full story under "Projects"). The transmitter and receivers have now been re-programmed to run only on the legal frequencies - with some considerable help from Tobe - so I can now reveal what was in the box!

First up, a very nice looking transmitter:

I do love Swedish minimalist design! :D Not only does it look good, but the stick unit feels every bit as good as similar mass produced units, such as the Dunhams. It appears that like me, Tobe likes strong stick springs! I can never get modern transmitters set hard enough for my liking! I think it was Phil Kraft who said "Soft springs sell transmitters. Strong springs win competitions!". Probably explains why I've never been very good in competitions! (That's my excuse and I'm sticking to it!)

The transmitter appears to be 6 channel, but only four are connected at present. Channels 1 & 2 are rudder and elevator. Channel 3 is a progressive throttle, controlled by the two push buttons. Channel 4 is a proportional throttle channel (as an alternative) controlled by the "trim" slider nearest the on-off switch. Like me again, Tobe has put the elevator trim nearest the edge of the case, where it is much easier to reach with the right thumb!

The system came with three six channel and two four channel receivers:

Two of the six channel receivers came with wire whisker aerials, and one with a PCB type. One receiver has the servo connectors projecting from the end of the case, whilst the others are vertical. Similarly, the two four channel receivers have alternative connection configurations.

All the receivers are very small! Much smaller than the old "MiniMac" single channel receivers that many older modellers will remember with affection! (Still got mine, still works!)

Next there are the servos. First up is a GG servo, clearly inspired by the Rand actuator:

Very neat! It also contains a re-coder / amplifier enabling it to operate with any conventional receiver and provide flapping rudder and elevator controls (Galloping Ghost). It seems to be smaller than I recall the Rand device being.

Also in the box were some "Pulse" servos - a two servo "brick" and a single servo.

These are spring-centred, open-loop servos (no feedback pot) and come complete with the built in re-coder / amplifiers to enable them to work with any standard receiver. The servos "wiggle" in use. One of the most reliable of the early American proportional sets was the DB Quadruplex, which operated in just this manner, using Graupner Bellamatic servos. The Bellamatic was a spring centred servo, which made it ideal for early pulse proportional systems, and Tobe's servos operate in a very similar manner. With these servos it would be very easy to replicate a DB Quadruplex controlling aileron, elevator and rudder, with an ESC for throttle.

The final servo(s) is another two channel "brick", but this time fully proportional feedback servos of Tobe's own design. These are very neat and light - perfect for small models!

But there's more!

The box also contained a spare encoder and RF board:

Digging deeper into the packing I discovered this:

A complete triple-axis stick unit! Clearly something else for which Tobe and I share an affection! My aerobatic models are now flown exclusively with a single-stick transmitter, which I much prefer for that application over twin-sticks! Looks like I'll soon have another tranny to use for this!

There was also a bag containing an assortment of trim levers, auxiliary control levers, a voltmeter and the mounting plate for the nRF module. In short, enough bits to build another transmitter!

The amount of work that has gone into creating - and 3D printing - these parts is staggering. The quality is superb. If you close your eyes, the sticks feel like a professionally manufactured system, not a home-built. They look good, too!

Quite honestly, I feel completely overwhelmed by Tobe's generosity in offering this prize. It would have been excellent if it had just been the transmitter and receiver, but to get all these extras as well is beyond belief!

Thank you so much, Tobe!

Very nice, and typical Tobe, a very giving and generous individual! You are so lucky!
