Many thanks - it's easy to get details now i know. I'll have to see how it goes David

I picked this up the other day. Anyone any ideas as to what it is? No visible manufacturers marks.

Hi - what dp are the Macnum pinions? and who also supplies this pitch? I have some old tamiya ones but they don't 'feel' right when I mesh them

The main battery was probably flat - I bet it went OK if you accelerated slowly or downhill - but not uphill. Good cars though - well impressed with our truggy - seems strong

I don't know about masks etc - but is the XT-Pro shell better than the one supplied with the Macnum? My boy punched some great holes in his shell after barrel rolling into some rocks - and he wants a new one now. Otherwise, can anyone suggest a strong replacement shell?

Hi there - my son has just punched a huge hole in his body shell after a huge roll - any advice on a nice strong replacement shell? Or would I better to pick up an XT-Pro which will give him better shocks (and body?) and some spares. Oh - and any advice on a motor with more zip than the standard one?

My son got a Macnum plus bearing kit off ebay for Christmas and I'm certainly impressed for the money and he loves it. It's a basic kit; I think they're missing a bit of a trick by not offering a hop up pack - say better shocks, different spur and pinions pack - but it is way better than the Tamiya stuff i used to use 20 years ago. Quite simple to work on too. Goes great on our local golf course. No idea how it compares generally with other up to date designs though or how it would race. The XT Pro is a pimped up version for those already in the RC game

One question on gearing - how much play should there be between the pinion and the spur? Having them with no 'play' surely leads to lots of wear - but too far apart would mean just the tips of the teeth touching - which would again give lots of wear - and possibly break the teeth of the spur gear if shock loaded? Any advice on this?

The Smacker and Flash are a bit tricky to build - Macnum looks good but there seem to be more Mad rats about. Our Macnum has been great fun to date. Much easier to change motors and gearing etc than the Smacker. We usually get about 15 minutes from a 3000mAH battery pack but the motor is quite mild although fast enough to get it off the ground on the local golf club. Macnum has good ground clearance.

Yes - my boy's car came with prebuilt plastic ones - trades descriptions act .... They are a bit weak and the top tends to pop off if you hit big bumps very hard - but otherwise it's a pretty nifty motor for the money. He's well pleased If you need spares get XT Pro ones - bit dearer but better

I took my flash out on the compacted snow etc on the road and it was great fun jumping off the kerbs etc. Probably about 15mins run time from a 3000maH battery - but I'm not sure how well charged it was and I'd barely used it before then. Three or four minutes is a bit poor - I'd reckon charger problem first, then battery, then internal car electrics. I'm hoping to compare it with my boy's macnum over the weekend with which I'm well impressed. We might be able to use the local skatepark.....otherwise back down the golf course to annoy people with strange dress sense....

If you've not yet bought one my son just got a Macnum and I'm quite impressed - the top of the shocks can pop off - but pretty fast and he is well impressed. Spares seem to be cheap too

Hi there; I've just aquired an old KA-1 speed controller for my Royal Flash- but no instructions :-( Can anyone assist? It's white body with gold heatsink but no visible set up buttons etc, cheers David

I took my son's new Macnum out on the icy old road outside earlier and it was great - until I broke a front suspension arm :-( Was I just unlucky - and does anyone do hop up parts for this car? I know the T piece at the back is supposed to be weak so i might as well get a few spares in in one go - any advice gratefully received - I need to get back in his good books.....

My son has just finished building his new Macnum - a Christmas present because he liked the 'bullet' graphics on the box - and he's taken it for a spin. He's well pleased! I thought I'd put my comments on here for others. As others have found, the manual is a little basic - there is no doubt the Tamiya manuals cover construction in greater depth and in a clearer order - but it was OK and does at least now show the size of screw etc (unlike the Royal Flash manual...). I had to help a little with some of the E clips that are used but basically he built it on his own, fitted some old radio gear and a Tamiya ESC101 and off he went. Other tricky parts were assembling the slipper clutch and getting gears to mesh smoothly. Most of the bolts are hex heads. Steering servo mount needed a bit of adjustment. I got some ball races for the car rather than the standard bushes. The use of a 3mm tap to cut decent threads in the plastic parts definitely helped and I'd pre thread all joints before assembly. He found popping the ball joints on to be difficult - but at least he did not use excessive force and break them. He did the ball diff on his own and it's well smooth. The dampers were pre assembled - we just had to add oil - and they work well. I've been told that the body shell protects them and the shock towers better than the Mad rat shell if you roll it. I think the springs are a bit soft personally. The drive shafts are pre-assembled. The body shell is quite thin. All the parts seem quite substantial and strong to me (although I've been out of this game for some years). It seemed very slow initially but a fresh battery gave a good turn of speed. The turning circle is good and it went really well off road down the local golf course with loads of grip on the bumpy bits round the greens. I'm very impressed for a 2 wheel drive car - way better than my old Tamiya Frog. The rear tyres are a sort of pin pattern with fronts a ribbed design. He's not taken it through the bunkers yet... but has got it well muddy in the back garden. No significant jumps with it yet. I might make up a basic front bumper before he hits something very hard. For the money I'm impressed and the box is big enough to hold the assembled car. Nice touches include the moulded on grips for the motor wires. Suggestions for others - make sure you have tools (none in the kit unlike Tamiya), take care with the E clips, there does not appear to be a location for the radio gear switch. There is no setup advice in the manual for spring tensions etc. I'm not sure I'd call this a starter car - you do really need access to some good tools but it's very good fun for the money. I'll compare it with my ebay sourced second hand Royal Flash in a week or two when I get it running.
